# Health Endpoints Guide

## Overview

PraisonAIUI provides multiple health endpoints optimized for different use cases:

- **`/health/live`** - Fast liveness check (<500ms)
- **`/health/ready`** - Readiness check with optional deep checks
- **`/health`** - Legacy endpoint (backward compatibility)

## Endpoints

### Liveness Check: `/health/live`

Fast endpoint to verify the server is running. Returns immediately with minimal processing.

**Use for:**
- Load balancer health probes
- Kubernetes liveness probes
- High-frequency monitoring

**Response time:** <500ms (typically <100ms)

**Example:**
```bash
curl http://localhost:8082/health/live
```

**Response:**
```json
{
  "status": "ok",
  "timestamp": "2024-01-20T10:30:00.000Z"
}
```

### Readiness Check: `/health/ready`

Verifies the server is ready to handle requests. Performs parallel health checks on all features with timeout protection.

**Use for:**
- Kubernetes readiness probes
- Pre-deployment validation
- Detailed diagnostics

**Query parameters:**
- `?deep=false` - Skip feature checks for faster response

**Response time:** 
- With deep checks: <1s (parallel execution)
- Without deep checks: <200ms

**Example:**
```bash
# Full readiness check
curl http://localhost:8082/health/ready

# Basic readiness (no feature checks)
curl http://localhost:8082/health/ready?deep=false
```

**Response with deep checks:**
```json
{
  "status": "ok",
  "timestamp": "2024-01-20T10:30:00.000Z",
  "provider": {
    "name": "PraisonAIProvider",
    "status": "ok"
  },
  "features": {
    "agents": {"status": "ok", "feature": "agents"},
    "chat": {"status": "ok", "feature": "chat"},
    "memory": {"healthy": false, "detail": "timeout"}
  }
}
```

### API Health: `/api/health`

Cached version of readiness check for dashboard polling. 30-second TTL to reduce load.

**Use for:**
- Dashboard health indicators
- Frequent client polling
- Status pages

**Response:** Same as `/health/ready` but cached for 30 seconds

## Deployment Configurations

### Kubernetes

```yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: praisonaiui
spec:
  template:
    spec:
      containers:
      - name: praisonaiui
        image: praisonaiui:latest
        livenessProbe:
          httpGet:
            path: /health/live
            port: 8082
          initialDelaySeconds: 10
          periodSeconds: 10
          timeoutSeconds: 2
        readinessProbe:
          httpGet:
            path: /health/ready?deep=false
            port: 8082
          initialDelaySeconds: 5
          periodSeconds: 5
          timeoutSeconds: 3
```

### AWS ALB/ELB

```terraform
resource "aws_lb_target_group" "praisonaiui" {
  health_check {
    enabled             = true
    path                = "/health/live"
    interval            = 30
    timeout             = 5
    healthy_threshold   = 2
    unhealthy_threshold = 2
  }
}
```

### Docker Compose

```yaml
services:
  praisonaiui:
    image: praisonaiui:latest
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:8082/health/live"]
      interval: 30s
      timeout: 5s
      retries: 3
      start_period: 10s
```

### Nginx

```nginx
upstream praisonaiui {
    server backend1:8082 max_fails=2 fail_timeout=5s;
    server backend2:8082 max_fails=2 fail_timeout=5s;
    
    # Health check configuration
    check interval=5000 rise=2 fall=3 timeout=2000 type=http;
    check_http_send "GET /health/live HTTP/1.0\r\n\r\n";
    check_http_expect_alive http_2xx;
}
```

## Migration Guide

If you're upgrading from a version using only `/health`:

1. **Update monitoring:** Change health checks to use `/health/live` for liveness
2. **Update readiness:** Use `/health/ready?deep=false` for readiness probes
3. **Update dashboards:** Point status indicators to `/api/health` (cached)
4. **Backward compatibility:** The `/health` endpoint remains available but may be slow

## Performance Characteristics

| Endpoint | Cold Start | Warm (p50) | Warm (p95) | Use Case |
|----------|------------|------------|------------|----------|
| `/health/live` | <100ms | <20ms | <50ms | Liveness probes |
| `/health/ready?deep=false` | <200ms | <50ms | <100ms | Basic readiness |
| `/health/ready` | <1s | <500ms | <800ms | Full diagnostics |
| `/api/health` (cached) | <1s* | <20ms | <50ms | Dashboard polling |

*First request only, then cached for 30s

## Troubleshooting

### Slow `/health` responses

If you're seeing slow responses on the legacy `/health` endpoint:
- Switch to `/health/live` for fast checks
- Use `/health/ready?deep=false` if you don't need feature health
- Enable caching with `/api/health` for frequent polling

### Feature timeouts

Features that timeout in `/health/ready` will show:
```json
{
  "feature_name": {
    "healthy": false,
    "detail": "timeout"
  }
}
```

This indicates the feature took longer than 500ms to respond. The server is still operational, but that specific feature may be experiencing issues.

### High latency under load

Under high load, use `/health/live` exclusively for monitoring. It has minimal overhead and won't impact performance.

## Composition

Components are designed to compose. Use `columns()` for horizontal layout within a `layout()`:

```python
@aiui.page("overview", title="Overview", icon="📊")
async def overview():
    return aiui.layout([
        # Row of KPI cards
        aiui.columns([
            aiui.metric("Users", value=142, delta="+12%"),
            aiui.metric("Revenue", value="$1.5k", delta="+8%"),
            aiui.metric("Uptime", value="99.9%"),
        ]),
        # Tabbed data
        aiui.tabs([
            {"label": "Table", "children": [
                aiui.table(
                    headers=["Agent", "Tasks", "Status"],
                    rows=[["Researcher", 15, "Active"]],
                ),
            ]},
            {"label": "Chart", "children": [
                aiui.chart("Tasks", data=[{"name": "Researcher", "value": 15}]),
            ]},
        ]),
        # Footer
        aiui.text("Data refreshes every 30 seconds."),
    ])
```

## Component Count Summary

| Category | Components | Count |
|----------|-----------|-------|
| Core | `layout`, `card`, `columns`, `table`, `text`, `chart` | 6 |
| Essential | `metric`, `progress_bar`, `alert`, `badge`, `separator`, `tabs`, `accordion`, `image_display`, `code_block`, `json_view` | 10 |
| Form Inputs | `text_input`, `number_input`, `select_input`, `slider_input`, `checkbox_input`, `switch_input`, `radio_input`, `textarea_input`, `multiselect_input`, `date_input`, `time_input`, `color_picker_input` | 12 |
| Layout & Advanced | `container`, `expander`, `divider`, `header`, `markdown_text`, `link`, `button_group`, `stat_group`, `avatar`, `callout`, `empty`, `spinner` | 12 |
| Media | `audio_player`, `video_player`, `file_download`, `gallery` | 4 |
| Dashboard | `toast`, `dialog`, `caption`, `html_embed`, `skeleton`, `tooltip_wrap` | 6 |
| Navigation | `breadcrumb`, `pagination`, `key_value_list`, `popover` | 4 |
| **Total** | | **54** |

## Custom Component Types

The `dashboard.js` renderer supports any dict with a `type` key. Unknown types render as formatted JSON, making it safe to experiment:

```python
# Custom component — renders as JSON until frontend support is added
{"type": "timeline", "events": [{"time": "10:00", "label": "Deploy"}]}
```

---

## Component Render Protocol

Understanding how components flow from Python to the browser.

### Data Flow

```
Python                    Server                     Frontend
──────                    ──────                     ────────
aiui.card("X", value=42)  →  {"type":"card",...}    →  renderComponent()
                             ↓                          ↓
@aiui.page() handler      →  /api/pages/{id}/data   →  renderCard()
                             ↓                          ↓
aiui.layout([...])        →  {"_components":[...]}  →  DOM elements
```

### Step-by-Step

1. **Python**: Call `aiui.card("Revenue", value="$1,500")` — returns a dict:
   ```python
   {"type": "card", "title": "Revenue", "value": "$1,500"}
   ```

2. **Server**: `@aiui.page()` handler returns `aiui.layout([...])`:
   ```python
   {"_components": [{"type": "card", ...}, {"type": "table", ...}]}
   ```

3. **API**: `GET /api/pages/{id}/data` returns the JSON

4. **Frontend**: `dashboard.js` detects `_components` key and calls `renderComponents()`:
   ```javascript
   function renderComponents(data, container) {
       if (data && data._components) {
           data._components.forEach(comp => {
               container.appendChild(renderComponent(comp));
           });
       }
   }
   ```

5. **Renderer**: `renderComponent(comp)` dispatches on `comp.type`:
   ```javascript
   function renderComponent(comp) {
       switch (comp.type) {
           case 'card': return renderCard(comp);
           case 'table': return renderTable(comp);
           // ... 48 component types
           default: return renderAsJSON(comp);
       }
   }
   ```

6. **DOM**: Each renderer creates HTML elements with `db-*` CSS classes

### The `_components` Key

The magic key that triggers structured rendering:

```python
# With _components — renders as UI elements
return {"_components": [aiui.card("X"), aiui.table(...)]}

# Without _components — renders as raw JSON
return {"status": "ok", "data": [...]}
```

`aiui.layout(children)` automatically wraps children in `{"_components": [...]}`.

### Component Dict Protocol

Every component function returns a dict with:

| Key | Required | Description |
|-----|----------|-------------|
| `type` | ✅ | Component type name (e.g. `"card"`, `"table"`) |
| Other keys | Varies | Component-specific properties |

```python
# Card component
{"type": "card", "title": "Revenue", "value": "$1,500", "footer": "+8%"}

# Table component
{"type": "table", "headers": ["A", "B"], "rows": [["x", "y"]]}

# Nested components
{"type": "columns", "children": [
    {"type": "card", "title": "A"},
    {"type": "card", "title": "B"},
]}
```

### CSS Classes

All components use `db-*` prefixed CSS classes:

| Component | CSS Class |
|-----------|-----------|
| Card | `.db-card`, `.db-card-title`, `.db-card-value`, `.db-card-footer` |
| Table | `.db-viewer table` |
| Alert | `.db-alert`, `.db-alert-info`, `.db-alert-success`, etc. |
| Badge | `.db-badge`, `.db-badge-secondary`, `.db-badge-destructive` |
| Tabs | `.db-tabs`, `.db-tab-list`, `.db-tab-btn`, `.db-tab-panel` |

### Extending with Custom Components

To add a new component type:

1. **Python**: Add function to `ui.py`:
   ```python
   def timeline(events: list[dict]) -> dict:
       return {"type": "timeline", "events": events}
   ```

2. **Frontend**: Add renderer to `dashboard.js`:
   ```javascript
   function renderTimeline(comp) {
       const el = document.createElement('div');
       el.className = 'db-timeline';
       // ... render events
       return el;
   }
   
   // Add to switch statement in renderComponent()
   case 'timeline': return renderTimeline(comp);
   ```

3. **CSS**: Add styles for `.db-timeline`

Until the frontend renderer is added, unknown types render as formatted JSON.

# Health API Reference

Source: https://ui.praison.ai/docs/api/health

# Health API Reference

The AIUI health API provides endpoints to monitor server and provider health status.

## Health Status Values

The following status values are used throughout the health API:

| Status | Meaning | Color Code |
|--------|---------|------------|
| `"ok"` | Service is functioning normally | Green |
| `"healthy"` | Service is functioning normally (legacy) | Green |
| `"degraded"` | Service is partially functional | Yellow |
| `"error"` | Service has errors | Red |
| `"unknown"` | Status cannot be determined | Yellow |

> **Note:** Both `"ok"` and `"healthy"` indicate successful operation. The system accepts either value for backward compatibility.

## Endpoints

### GET /health

Returns the overall server health status.

**Response:**
```json
{
  "status": "ok",
  "timestamp": "2026-06-23T10:00:00Z",
  "integrated": true,
  "sdk_gaps": []
}
```

### GET /api/provider

Returns information about the active AI provider.

**Response:**
```json
{
  "name": "PraisonAIProvider",
  "module": "praisonaiui.providers",
  "status": "ok",
  "agents": []
}
```

### GET /api/provider/health

Returns detailed JSON health information from the provider gateway. Always
responds with `Content-Type: application/json`. The base fields from the
provider's `health()` payload are merged with the normalised fields below.

**Response:**
```json
{
  "status": "ok",
  "provider": "PraisonAIProvider",
  "type": "PraisonAIProvider",
  "agents": 5,
  "detail": "ok"
}
```

| Field | Type | Description |
|-------|------|-------------|
| `status` | string | One of the health status values above. |
| `type` | string | Provider type (from `provider` field, falls back to class name). |
| `agents` | integer | Count of agents reported by the provider. |
| `detail` | string | Human-readable detail; `"ok"` for healthy providers. |

> **Note:** Any unmatched `/api/*` path returns a JSON `404` (never the SPA
> HTML shell), so API clients can rely on parsing the response body.

## CLI Commands

### health-check

Check server health status:

```bash
aiui health-check --server http://127.0.0.1:8000
```

The command displays:
- Green panel for `"ok"` or `"healthy"` status
- Yellow panel for other statuses
- Red error message if server is unreachable

### doctor

Run comprehensive diagnostics:

```bash
aiui doctor --server http://127.0.0.1:8000
```

The doctor command checks:
1. Server Health
2. Provider Status
3. Gateway Status
4. Features Loaded
5. Config Store
6. Datastore
7. Channels

### provider status

Check provider health:

```bash
aiui provider status --server http://127.0.0.1:8000
```

## Python API

```python
from praisonaiui.health_utils import is_success_status

# Check if a status indicates success
if is_success_status("ok"):
    print("Service is healthy")

# Available success statuses
from praisonaiui.health_utils import SUCCESS_STATUSES
# frozenset({'ok', 'healthy'})
```

## JavaScript/Dashboard

The dashboard automatically accepts both `"ok"` and `"healthy"` as success statuses:

```javascript
const ok = d && (d.status === 'ok' || d.status === 'healthy');
```

---

### `aiui.set_custom_js(path)`

Inject a local JavaScript file into the UI. Reads the file at `path` and
serves it at `/custom.js`. A `<script src="/custom.js">` tag is injected
into the host HTML **after** the plugin loader, so `window.aiui` and all
registry APIs (`registerView`, `registerComponent`) are ready when your
code runs.

| Parameter | Type | Description |
|-----------|------|-------------|
| `path` | `str \| Path` | Local filesystem path to a `.js` file |

Raises `FileNotFoundError` if the path does not exist.

```python
import praisonaiui as aiui

aiui.set_custom_js("plugin.js")
```

Where `plugin.js` uses the client-side extension APIs:

```javascript
// plugin.js
window.aiui.registerComponent('timeline', function(comp) {
    const el = document.createElement('div');
    (comp.events || []).forEach(ev => {
        const row = document.createElement('div');
        row.textContent = `${ev.time} — ${ev.label}`;
        el.appendChild(row);
    });
    return el;
});
```

---

### `aiui.register_component_schema(component_type, schema)`

Register a JSON Schema contract for a component dict. Built-in schemas
are auto-derived from every `aiui.ui.*` builder at startup; user schemas
take priority and are merged on top.

| Parameter | Type | Description |
|-----------|------|-------------|
| `component_type` | `str` | Component type string (e.g. `"timeline"`) |
| `schema` | `dict` | JSON Schema dict (Draft 2020-12 compatible) |

```python
import praisonaiui as aiui

aiui.register_component_schema("timeline", {
    "type": "object",
    "required": ["type", "events"],
    "properties": {
        "type": {"const": "timeline"},
        "events": {"type": "array"},
    },
})
```

### `aiui.get_component_schemas()`

Returns the merged registry as a `dict[str, dict]`. Also available as a
JSON endpoint: `GET /api/components/schemas`.

```python
schemas = aiui.get_component_schemas()
print(sorted(schemas))   # ['accordion', 'alert', ..., 'timeline', ...]
```

---

### `aiui.prompt(question, *, options=None, timeout=300.0)`

Pause the agent and wait for the user to answer. Preferred entry point
for interactive agent flows — supersedes the legacy `AskUserMessage`
class.

| Parameter | Type | Description |
|-----------|------|-------------|
| `question` | `str` | Text shown to the user. |
| `options`  | `list[str] \| None` | Optional list of choices. When given, the user picks one; otherwise they type free text. |
| `timeout`  | `float` | Seconds to wait before giving up. Default 300 (5 min). |

Returns a `PromptResult` dataclass (`text`, `choice`, `message_id`).
The result is truthy when the user answered, falsy on timeout.

```python
import praisonaiui as aiui

@aiui.reply
async def on_message(msg: str):
    name = await aiui.prompt("What's your name?")
    if name:
        await aiui.say(f"Hi {name.text}!")

    pick = await aiui.prompt("Pick a colour", options=["red", "blue"])
    if pick:
        await aiui.say(f"You picked {pick.choice}")
```

---

### `aiui.error(content, *, details=None)`

Emit an error message to the chat. A thin helper around `Message` with
`metadata={"kind": "error"}` — keeps the public surface small.

```python
try:
    data = await fetch()
except Exception as exc:
    await aiui.error("Couldn't load data", details=str(exc))
```

---

### `aiui.configure(*, datastore=None, branding=None, theme=None, chat=None, custom_css=None, custom_js=None, style=None)`

One-stop configuration function. Every keyword is optional, so you only
set what you need. Replaces the dozen individual `set_*` setters for
most common cases (the `set_*` functions remain for advanced control).

| Parameter | Type | Description |
|-----------|------|-------------|
| `datastore` | `str` | Storage backend: `"memory"`, `"json"`, `"json:/path"`, `"sdk"`, `"sdk:/path"`. |
| `branding`  | `dict` | Forwarded to `set_branding(...)`. Keys: `title`, `logo`, `subtitle`. |
| `theme`     | `dict` | Forwarded to `set_theme(...)`. Keys: `preset`, `dark`/`dark_mode`, `radius`, `brand_color`. |
| `chat`      | `dict` | Forwarded to `set_chat_features(...)`. Keys: `feedback`, `mode`, plus any chat-feature flag. |
| `custom_css`| `str \| Path` | Path to a CSS file; same as `set_custom_css`. |
| `custom_js` | `str \| Path` | Path to a JS file; same as `set_custom_js`. |
| `style`     | `str` | UI style — `"chat"`, `"dashboard"`, etc. |

```python
import praisonaiui as aiui

aiui.configure(
    branding={"title": "My App", "logo": "🎨"},
    theme={"preset": "ocean", "dark": True, "radius": "md"},
    chat={"feedback": True, "mode": "single"},
    datastore="json",
    custom_css="styles.css",
    custom_js="plugin.js",
)
```

```python
import praisonaiui as aiui

# In-memory (default, volatile)
aiui.configure(datastore="memory")

# JSON files at ~/.praisonaiui/sessions/
aiui.configure(datastore="json")

# JSON files at custom path
aiui.configure(datastore="json:/tmp/my-sessions")

# SDK-backed store (unifies with praisonai-agents)
aiui.configure(datastore="sdk")
```

---

## Callback Decorators

### `@aiui.reply`

Handle incoming chat messages. This is the core callback.

```python
@aiui.reply
async def on_reply(message):
    await aiui.stream("Thinking...")
    # Process message.content
    await aiui.say("Here's the answer!")
```

The `message` object has:
- `message.content` — user's text
- `message.session_id` — session identifier
- `message.images` — attached images (if any)

---

### `@aiui.welcome`

Send a welcome message when a user connects.

```python
@aiui.welcome
async def on_welcome():
    await aiui.say("Welcome! How can I help you today?")

### `@aiui.goodbye`

Cleanup when a user disconnects.

```python
@aiui.goodbye
async def on_goodbye():
    await aiui.say("Goodbye! Your session has been saved.")
```

---

### `@aiui.starters`

Define conversation starters shown to new users.

```python
@aiui.starters
async def on_starters():
    return [
        {"label": "What can you do?", "message": "Tell me about your capabilities"},
        {"label": "Help me write", "message": "Help me draft an email"},
    ]
```

---

### `@aiui.profiles`

Define chat profiles (agent personas users can choose).

```python
@aiui.profiles
async def on_profiles():
    return [
        {"name": "Expert", "description": "Expert mode", "icon": "🎓"},
        {"name": "Creative", "description": "Creative writer", "icon": "✍️"},
    ]
```

---

### `@aiui.page(slug, title, icon, group, order)`

`aiui test`. These run against a live server and verify chat, memory, sessions,
and API endpoint health.

### Quick Start

```bash
# Start the server
aiui run app.py --port 8082

# In another terminal, run all tests
aiui test all --server http://127.0.0.1:8082
```

# Architecture: AG-UI Protocol vs Gateway Integration

Source: https://ui.praison.ai/docs/concepts/architecture

# Architecture: AG-UI Protocol vs Gateway Integration

PraisonAIUI has **two complementary integration layers** with the praisonai backend. They solve different problems and run side-by-side.

## Protocol Stack

```mermaid
graph TD
    subgraph "PraisonAIUI Frontend (React SPA)"
        CHAT["Chat Panel"]
        DASH["Admin Dashboard"]
    end

    subgraph "praisonai-package Backend"
        AGUI["AGUI Class<br/>POST /agui<br/>SSE streaming"]
        GW["WebSocketGateway<br/>REST + WebSocket<br/>Bot management"]
    end

    CHAT -->|"WebSocket / SSE<br/>(RunEvent protocol)"| GW
    CHAT -.->|"AG-UI (optional)<br/>POST /agui"| AGUI
    DASH -->|"REST API<br/>(/api/channels, /api/nodes)"| GW
```

AG-UI sits alongside MCP and A2A in the agentic protocol stack:

| Protocol | Purpose |
|----------|---------|
| **MCP** | Gives agents tools |
| **A2A** | Agent-to-agent communication |
| **AG-UI** | Agent-to-user-interface (streaming) |
| **Gateway** | Infrastructure management (channels, nodes, instances) |

## AG-UI — The Conversation Layer

[AG-UI](https://ag-ui.com/) is an **open, event-based protocol** by CopilotKit that standardizes how agent backends stream events to frontends. PraisonAI implements it at `praisonaiagents/ui/agui/`.

**What it does:** Streams ~16 standard event types (text deltas, tool calls, state sync, generative UI) over SSE.

**Who uses it:** LangGraph, CrewAI, Google ADK, Microsoft Agent Framework, AWS Strands, Mastra, Pydantic AI, LlamaIndex, AG2, and PraisonAI.

### Usage

```python
from praisonaiagents import Agent
from praisonaiagents.ui.agui import AGUI
from fastapi import FastAPI

agent = Agent(name="Assistant", role="Helper", goal="Help users")
agui = AGUI(agent=agent)

app = FastAPI()
app.include_router(agui.get_router())
# → POST /agui  (SSE streaming, AG-UI protocol)
# → GET  /status (agent availability)
```

**Frontend compatibility:** CopilotKit, or any AG-UI-compatible client.

## Gateway Integration — The Operations Layer

The gateway integration connects PraisonAIUI's dashboard features to the live `WebSocketGateway` backend for infrastructure management.

**What it does:** CRUD for channels, nodes, instances; live bot status; heartbeat monitoring.

### How It Works

```mermaid
sequenceDiagram
    participant S as AIUIGateway.start()
    participant R as _gateway_ref singleton
    participant C as channels.py
    participant N as nodes.py
    participant G as WebSocketGateway

    S->>R: set_gateway(ws_gateway)
    C->>R: get_gateway()
    R-->>C: returns WebSocketGateway
    C->>G: health()
    G-->>C: Live bot status
    N->>R: get_gateway()
    R-->>N: returns WebSocketGateway
    N->>G: health()
    G-->>N: Agent/session counts
```

### Key Files

| File | Purpose |
|------|---------|
| `features/_gateway_ref.py` | Thread-safe singleton holding reference to the live gateway |
| `features/channels.py` | Channel CRUD + live status enrichment from gateway |
| `features/nodes.py` | Node CRUD + gateway health enrichment |
| `integration.py` | Calls `set_gateway()` on start, clears on stop |
| `config_store.py` | Unified `~/.praisonaiui/config.yaml` — single source of truth for all feature state |

### API Endpoints

| Endpoint | Methods | Description |
|----------|---------|-------------|
| `/api/channels` | GET, POST | List/create channels |
| `/api/channels/{id}` | GET, PUT, DELETE | Channel CRUD |
| `/api/channels/{id}/toggle` | POST | Enable/disable |
| `/api/channels/{id}/status` | GET | Live running status |
| `/api/channels/platforms` | GET | Supported platforms |
| `/api/nodes` | GET, POST | List/register nodes |
| `/api/nodes/{id}` | GET, PUT, DELETE | Node CRUD |
| `/api/nodes/{id}/status` | GET | Node status + gateway enrichment |
| `/api/nodes/{id}/agents` | GET, PUT | Agent bindings |
| `/api/instances` | GET | Connected instances |
| `/api/instances/heartbeat` | POST | Presence heartbeat |

## Using Both Together

`AIUIGateway.start()` in `integration.py` mounts the gateway and dashboard REST API on one server. Chat uses the built-in WebSocket/SSE `RunEvent` protocol; AG-UI is mounted separately via `AguiFeature` when enabled:

```python
from praisonaiui.integration import AIUIGateway
from praisonaiagents import Agent

gateway = AIUIGateway(port=8080, static_dir="./dist")
agent = Agent(name="assistant", instructions="You are helpful.")
gateway.register_agent(agent)

await gateway.start()
# Chat:  POST /run, WS /api/chat/ws  → RunEvent streaming (built-in)
# AG-UI: POST /agui, GET /agui/status → CopilotKit-compatible SSE (AguiFeature)
# Admin: GET  /api/channels            → Gateway REST API
# Admin: GET  /api/nodes               → Gateway REST API
# WS:    /ws                           → Legacy gateway WebSocket
# A2UI:  GET/POST /api/surfaces/*      → Agent-driven surfaces (SurfaceFeature)
```

## Summary

| | AG-UI (`/agui`) | Gateway (`/api/*`) |
|---|---|---|
| **Layer** | Conversation | Operations |
| **Transport** | SSE (server-sent events) | REST + WebSocket |
| **Purpose** | Stream agent responses to users | Manage channels, nodes, instances |
| **Frontend** | CopilotKit / AG-UI clients | PraisonAIUI React dashboard |
| **Protocol** | Open standard (~16 event types) | Internal REST API |

# YAML Configuration

Complete guide to the `aiui.template.yaml` configuration schema.

## Overview

PraisonAIUI uses a single YAML file to configure your entire site. This file defines:

- **Site metadata** - Title, description, theme
- **Content sources** - Where to find your docs
- **Components** - Reusable UI elements
- **Templates** - Page layouts with slots
- **Routes** - URL patterns to template mappings

## Schema Version

Always specify the schema version:

```yaml
schemaVersion: 1
```

## Site Configuration

```yaml
site:
  title: "My Documentation"          # Required
  description: "Site description"    # Optional
  routeBaseDocs: "/docs"             # Default: /docs
  ui: "shadcn"                       # Theming hint (shadcn | mui | chakra)
  theme:
    preset: "zinc"                   # Any Tailwind color (22 options)
    radius: "md"                     # none | sm | md | lg | xl
    darkMode: true
```

> **Note**: The `ui` field is a theming hint. Components are UI-agnostic and use CSS classes you can style with any framework.

## Component Dependencies

Auto-install shadcn components at build time:

```yaml
dependencies:
  shadcn:
    - accordion
    - tabs
    - dialog
```

When you run `aiui build`, any missing components are automatically installed via `npx shadcn add`.

## Content Sources

```yaml
content:
  docs:
    dir: "./docs"                    # Path to docs folder
    include:                         # Glob patterns
      - "**/*.md"
      - "**/*.mdx"
    exclude:                         # Excluded patterns
      - "**/drafts/**"
    indexFiles:
      - "index.md"
      - "README.md"
    nav:
      mode: "auto"                   # auto | manual
      sort: "filesystem"             # filesystem | alpha | date
      collapsible: true
      maxDepth: 4
```

## Components

Define reusable components:

```yaml
components:
  my_header:
    type: "Header"
    props:
      logoText: "My Site"
      cta:
        label: "Get Started"
        href: "/docs"

  my_footer:
    type: "Footer"
    props:
      text: "© 2024"
```

### Built-in Component Types

| Type | Description |
|------|-------------|
| `Header` | Site header with logo, nav, CTA |
| `Footer` | Site footer |
| `DocsSidebar` | Documentation sidebar navigation |
| `Toc` | Table of contents |
| `DocContent` | Rendered markdown content |

## Templates

Templates combine a layout with slot assignments:

```yaml
templates:
  docs:
    layout: "ThreeColumnLayout"
    slots:
      header: { ref: "my_header" }     # Reference a component
      left: { ref: "sidebar_docs" }
      main: { type: "DocContent" }     # Direct type assignment
      right: { type: "Toc" }
      footer: { ref: "my_footer" }
```

### Layouts

| Layout | Description |
|--------|-------------|
| `ThreeColumnLayout` | Sidebar + Content + TOC |
| `TwoColumnLayout` | Sidebar + Content |
| `CenteredLayout` | Centered content, no sidebar |
| `FullWidthLayout` | Full width content |
| `FlexibleLayout` | WordPress-style widget zones |

## Widget Zones

Place widgets in layout zones without modifying markdown:

```yaml
templates:
  docs:
    layout: "FlexibleLayout"
    zones:
      rightSidebar:
        - type: "Toc"
        - type: "StatsCard"
          props:
            title: "Users"
            value: "15,231"
            change: "+20%"
      footer:
        - type: "Newsletter"
        - type: "Copyright"
          props:
            text: "© 2024"
```

### Available Zones

| Zone | Description |
|------|-------------|
| `header` | Top header |
| `topNav` | Below header nav |
| `hero` | Hero banners |
| `leftSidebar` | Left column |
| `main` | Main content |
| `rightSidebar` | Right column |
| `bottomNav` | Pagination area |
| `footer` | Footer widgets |

### Built-in Widgets

| Widget | Description |
|--------|-------------|
| `StatsCard` | Metrics display |
| `QuickLinks` | Navigation links |
| `Newsletter` | Email signup |
| `HeroBanner` | Hero section |
| `SocialLinks` | Social icons |
| `Copyright` | Copyright text |

See [Widget Zones](../features/widget-zones.md) for full documentation.

## Routes

Map URL patterns to templates:

```yaml
routes:
  - match: "/docs/**"
    template: "docs"

  - match: "/docs/changelog"
    template: "docs"
    slots:
      right: null                      # Override: hide TOC
```

Route matching uses glob patterns:
- `*` - Single segment
- `**` - Multiple segments

## Complete Example

```yaml
schemaVersion: 1

site:
  title: "PraisonAI Docs"
  ui: "shadcn"
  theme:
    darkMode: true

content:
  docs:
    dir: "./docs"

components:
  header:
    type: "Header"
    props:
      logoText: "PraisonAI"

  footer:
    type: "Footer"
    props:
      text: "© 2024 Praison Limited"

  sidebar:
    type: "DocsSidebar"
    props:
      source: "docs-nav"

templates:
  docs:
    layout: "ThreeColumnLayout"
    slots:
      header: { ref: "header" }
      left: { ref: "sidebar" }
      main: { type: "DocContent" }
      right: { type: "Toc" }
      footer: { ref: "footer" }

routes:
  - match: "/docs/**"
    template: "docs"
```

## Runtime Persistence (`config.yaml`)

> **Single source of truth** for all runtime feature state.

In addition to `aiui.template.yaml` (which drives static site generation), PraisonAIUI uses a **unified runtime config file** at `~/.praisonaiui/config.yaml`. This file stores all feature state — agents, channels, guardrails, schedules, and runtime settings — in a single YAML file that persists across server restarts.

This is compatible with the `gateway.yaml` schema used by `praisonai gateway start --config`.

### Schema

```yaml
# ~/.praisonaiui/config.yaml (auto-generated)
schemaVersion: 2

server:
  host: "127.0.0.1"
  port: 8003

provider:
  name: "openai"
  model: "gpt-4o-mini"

gateway:
  host: "127.0.0.1"
  port: 8765

# Agent definitions (same schema as gateway.yaml)
agents:
  personal:
    name: "Personal Assistant"
    instructions: "You are a friendly personal assistant."
    model: "gpt-4o-mini"
    tools: ["internet_search"]

# Messaging channels
channels:
  telegram_bot:
    name: "My Bot"
    platform: "telegram"
    config:
      bot_token: "${TELEGRAM_BOT_TOKEN}"

# Runtime configuration (set via /api/config/runtime)
runtime_config:
  model: "gpt-4o"
  temperature: 0.7

# Guardrail definitions
guardrails:
  registry:
    polite_check:
      description: "Output must be polite"

# Scheduled jobs
schedules:
  jobs:
    daily_report:
      name: "Daily Report"
      schedule:
        kind: every
        every_seconds: 86400
```

### How It Works

All CRUD operations (dashboard, REST API, CLI) **automatically write back** to this file:

| Feature | Section | Written On |
|---------|---------|------------|
| Config Runtime | `runtime_config` | PATCH, PUT, DELETE, apply |
| Guardrails | `guardrails` | Register |
| Channels | `channels` | Add, update, delete |
| Schedules | `schedules` | Add, remove, update |
| Agents | `agents` | Create, update, delete |

- **Atomic writes**: Uses `tempfile` + `os.rename()` to prevent corruption.
- **Hot reload**: The [Config Hot-Reload](../features/config-hot-reload.md) feature watches this file for external changes.
- **Environment variables**: Use `${ENV_VAR}` syntax for secrets (never stored in plaintext).

#### Environment Variable vs Config File

| | Env Variable | Config File |
|---|---|---|
| **Security** | ✅ Not in source control | ⚠️ Risk of committing secrets to git |
| **12-Factor App** | ✅ Standard practice | ❌ Violates config-as-env principle |
| **CI/CD** | ✅ Easy to inject per environment | ❌ Needs file management |
| **Docker/K8s** | ✅ Native secret support | ❌ Requires volume mounts |
| **Multiple envs** | ✅ Different key per env (dev/staging/prod) | ⚠️ Need separate config files |

**Rule of thumb**: Secrets (API keys, tokens) → environment variables. Preferences (model, theme, branding) → config file.

- **Custom path**: Set `PRAISONAIUI_CONFIG_PATH` to use a different file location.

### Relationship to `aiui.template.yaml`

| File | Purpose | Used By |
|------|---------|---------|
| `aiui.template.yaml` | Static site layout, components, routes | `aiui build`, `aiui dev` |
| `~/.praisonaiui/config.yaml` | Runtime feature state (agents, channels, config) | `aiui run`, dashboard API |
| `gateway.yaml` | Subset of `config.yaml` (legacy compatibility) | `praisonai gateway start` |

# Providers

Source: https://ui.praison.ai/docs/concepts/providers

# Providers

PraisonAIUI uses a **provider protocol** — a simple abstraction that lets you plug in any AI backend.

## Architecture

```mermaid
graph TD
    subgraph "Frontend (React)"
        UI["Dashboard / Chat / Agents"]
        SSE["SSE Stream Consumer"]
        API["REST API Client"]
    end

    subgraph "Server (server.py)"
        Routes["/run, /agents, /sessions, /api/*"]
        Provider["get_provider()"]
    end

    subgraph "Provider Protocol (BaseProvider)"
        direction LR
        Run["run() → AsyncIterator[RunEvent]"]
        List["list_agents() → List[dict]"]
        Health["health() → dict"]
    end

    subgraph "Pluggable Backends"
        P1["PraisonAIProvider (default)"]
        P2["OpenClawProvider"]
        P3["LangChainProvider"]
        P4["Custom Provider"]
    end

    UI --> API --> Routes --> Provider
    SSE --> Routes
    Provider --> Run
    Provider --> List
    Provider --> Health
    Run --> P1 & P2 & P3 & P4
```

The provider protocol is the **only contract** between the frontend and any AI backend. All dashboard pages (`/api/overview`, `/api/config`, `/api/logs`, etc.) are provider-agnostic — they always work regardless of which backend is active. The provider only handles agent execution (`run()`), agent listing (`list_agents()`), and health checks (`health()`).

## How It Works

1. User sends a message → `POST /run`
2. Server calls `provider.run(message)` on the active provider
3. Provider yields `RunEvent` objects (start, content, tool calls, reasoning, completion)
4. Server serialises each `RunEvent` to an SSE `data:` frame
5. Frontend `useSSE.ts` parses events and renders components

## Built-in Provider: PraisonAI

PraisonAI is the default provider. It wraps the `@aiui.reply` callback system:

```python
import praisonaiui as aiui

@aiui.reply
async def on_message(message: str):
    # Your AI logic here — PraisonAIProvider handles the rest
    await aiui.say("Hello!")
```

No extra config needed — `PraisonAIProvider` is used automatically.

### Agent Tools and Reflection

The default provider resolves tools for agents using `ToolResolver` from the `praisonai` package. Agents created via the CRUD API or `~/.praisonaiui/config.yaml` get their tool names (strings) automatically resolved to callable Python functions:

```python
# Agent definition with tools (via CRUD API or YAML):
# tools: ["internet_search", "wikipedia_search"]
#
# ToolResolver resolves these names from 4 sources:
# 1. Local tools.py file
# 2. praisonaiagents.tools.TOOL_MAPPINGS (built-in)
# 3. praisonai_tools package (community)
# 4. Tool registry (programmatic)
```

When no tools are configured, the provider gives agents sensible defaults (`internet_search`).

Agents also support `reflection: true` (default) for self-reflection mode, where the agent evaluates its own response quality before returning.

## Swapping Providers

```python
import praisonaiui as aiui

# Use a custom provider:
aiui.set_provider(MyCustomProvider())
```

## Writing a Custom Provider

Implement `BaseProvider.run()` — that's it:

```python
from praisonaiui.provider import BaseProvider, RunEvent, RunEventType

class EchoProvider(BaseProvider):
    """Echoes messages back — minimal example."""

    async def run(self, message, *, session_id=None, agent_name=None, **kw):
        yield RunEvent(type=RunEventType.RUN_STARTED)
        yield RunEvent(type=RunEventType.RUN_CONTENT, token=f"Echo: {message}")
        yield RunEvent(type=RunEventType.RUN_COMPLETED, content=f"Echo: {message}")
```

### Inline media (images, video, files)

Any provider can attach rich media to chat messages using ``MESSAGE_ELEMENT``
events. The UI renders them inline and persists them in session history.

```python
class ImageProvider(BaseProvider):
    async def run(self, message, *, session_id=None, agent_name=None, **kw):
        yield RunEvent(type=RunEventType.RUN_STARTED)
        # ... call your image API (OpenAI, Stability, custom, etc.) ...
        image_url = "https://example.com/generated.png"
        yield BaseProvider.message_element_event({
            "type": "image",
            "url": image_url,
            "alt": "Generated image",
        })
        yield RunEvent(type=RunEventType.RUN_COMPLETED, content="Here is your image.")
```

Tool results from PraisonAI agents are also detected automatically when they
match OpenAI image shapes (``{"data": [{"url": "..."}]}``) or explicit element
dicts — no provider code required.

Callback handlers can use ``Message.add_image()`` or ``await aiui.image(url)``
and the default ``PraisonAIProvider`` maps those to ``MESSAGE_ELEMENT`` events.

Full architecture, data flows, and tests: [Image Preview in Chat](../features/image-preview-chat.md).

### With Tool Calls and Reasoning

```python
class SmartProvider(BaseProvider):
    async def run(self, message, **kw):
        yield RunEvent(type=RunEventType.RUN_STARTED)

        # Emit reasoning steps (shown in ThinkingSteps component)
        yield RunEvent(type=RunEventType.REASONING_STARTED)
        yield RunEvent(type=RunEventType.REASONING_STEP, step="Analyzing the question...")
        yield RunEvent(type=RunEventType.REASONING_STEP, step="Searching knowledge base...")
        yield RunEvent(type=RunEventType.REASONING_COMPLETED)

        # Emit tool calls (shown in ToolCallDisplay component)
        yield RunEvent(
            type=RunEventType.TOOL_CALL_STARTED,
            name="web_search",
            args={"query": message},
        )
        yield RunEvent(
            type=RunEventType.TOOL_CALL_COMPLETED,
            name="web_search",
            result={"results": ["Found relevant info"]},
        )

        # Stream the response token by token
        for word in "Here is the answer".split():
            yield RunEvent(type=RunEventType.RUN_CONTENT, token=word + " ")

        yield RunEvent(type=RunEventType.RUN_COMPLETED, content="Here is the answer")
```

## RunEvent Reference

Every event has a `type` field and optional payload fields:

| Field | Type | Used By |
|-------|------|---------|
| `type` | `RunEventType` | All events |
| `content` | `str` | `RUN_COMPLETED`, `RUN_CONTENT` |
| `token` | `str` | `RUN_CONTENT` (streaming) |
| `name` | `str` | `TOOL_CALL_*` |
| `args` | `dict` | `TOOL_CALL_STARTED` |
| `result` | `any` | `TOOL_CALL_COMPLETED` |
| `step` | `str` | `REASONING_STEP` |
| `error` | `str` | `RUN_ERROR` |
| `agent_name` | `str` | Multi-agent events |
| `extra_data` | `dict` | Custom payload (includes `element` for `message_element`) |

# Slots & Components

Source: https://ui.praison.ai/docs/concepts/slots

# Slots & Components

Understanding the slot system and built-in components.

## Slot System

Slots are named insertion points in layouts. Each template assigns components to slots:

```yaml
templates:
  docs:
    layout: "ThreeColumnLayout"
    slots:
      header: { ref: "main_header" }
      left: { type: "DocsSidebar" }
      main: { type: "DocContent" }
      right: { type: "Toc" }
      footer: { ref: "main_footer" }
```

## Built-in Components

### Header

Site header with logo, navigation, and CTA.

```yaml
components:
  my_header:
    type: "Header"
    props:
      logoText: "My Site"
      logoHref: "/"
      links:
        - label: "Docs"
          href: "/docs"
        - label: "Blog"
          href: "/blog"
      cta:
        label: "Get Started"
        href: "/docs/quickstart"
```

### Footer

Site footer with links and copyright.

```yaml
components:
  my_footer:
    type: "Footer"
    props:
      text: "© 2024 My Company"
      links:
        - label: "GitHub"
          href: "https://github.com"
```

### DocsSidebar

Documentation navigation sidebar.

```yaml
components:
  sidebar:
    type: "DocsSidebar"
    props:
      source: "docs-nav"    # Uses generated navigation
      collapsible: true
      searchable: true
```

### Toc

Table of contents for the current page.

```yaml
slots:
  right: { type: "Toc" }
```

### DocContent

Renders the markdown content for the current page.

```yaml
slots:
  main: { type: "DocContent" }
```

## Custom Components

Override built-in components using the TypeScript SDK:

```typescript
import { SlotRegistry } from 'praisonaiui/runtime';

SlotRegistry.register('Header', MyCustomHeader);
```

# Templates & Layouts

Source: https://ui.praison.ai/docs/concepts/templates

# Templates & Layouts

Learn how templates and layouts work in PraisonAIUI.

## Overview

Templates define the structure of your pages by combining:
- A **layout** - The structural container
- **Slots** - Pluggable content areas

## Layouts

PraisonAIUI provides four layouts:

| Layout | Description |
|--------|-------------|
| `ThreeColumnLayout` | Sidebar + Content + TOC (classic docs) |
| `TwoColumnLayout` | Sidebar + Content (no TOC) |
| `CenteredLayout` | Centered content, no sidebar |
| `FullWidthLayout` | Full-width content |

### ThreeColumnLayout

The classic documentation layout with sidebar and TOC.

## Defining Templates

```yaml
templates:
  docs:
    layout: "ThreeColumnLayout"
    slots:
      header: { ref: "my_header" }
      left: { ref: "sidebar" }
      main: { type: "DocContent" }
      right: { type: "Toc" }
      footer: { ref: "my_footer" }
```

## Slot Assignment

Slots can be assigned in two ways:

### Reference (ref)
Point to a component defined in the `components` section:
```yaml
slots:
  header: { ref: "my_header" }
```

### Direct Type
Use a component type directly:
```yaml
slots:
  main: { type: "DocContent" }
```

### Null (hide)
Remove a slot entirely:
```yaml
slots:
  right: null
```

# Advanced Examples

Complex configurations and customization patterns.

## Multiple Templates

Different layouts for different sections:

```yaml
templates:
  docs:
    layout: "ThreeColumnLayout"
    slots:
      header: { ref: "header" }
      left: { type: "DocsSidebar" }
      main: { type: "DocContent" }
      right: { type: "Toc" }
      footer: { ref: "footer" }

  marketing:
    layout: "DefaultLayout"
    slots:
      header: { ref: "header" }
      hero: { type: "Hero" }
      main: { type: "PageContent" }
      footer: { ref: "footer" }

routes:
  - match: "/docs/**"
    template: "docs"

  - match: "/"
    template: "marketing"

  - match: "/pricing"
    template: "marketing"
```

## Route-Level Overrides

Override slots for specific pages:

```yaml
routes:
  - match: "/docs/**"
    template: "docs"

  - match: "/docs/changelog"
    template: "docs"
    slots:
      right: null  # Hide TOC on changelog

  - match: "/docs/api/**"
    template: "docs"
    slots:
      left: { type: "ApiSidebar" }  # Different sidebar
```

## Custom Components

Register custom components in TypeScript:

```typescript
// components/CustomHeader.tsx
import { SlotRegistry } from 'praisonaiui/runtime';

function CustomHeader({ logoText, links }) {
  return (
    <header className="custom-header">
      <h1>{logoText}</h1>
      <nav>
        {links.map(link => (
          <a key={link.href} href={link.href}>{link.label}</a>
        ))}
      </nav>
    </header>
  );
}

// Register to override default Header
SlotRegistry.register('Header', CustomHeader);
```

## Dark Mode with Custom Colors

```yaml
site:
  theme:
    darkMode: true
    brandColor: "emerald"
    radius: "lg"
```

```css
/* styles/globals.css */
:root {
  --brand-primary: #10b981;
  --brand-secondary: #34d399;
}

[data-theme="dark"] {
  --brand-primary: #34d399;
  --brand-secondary: #6ee7b7;
}
```

# A2UI canvas — agent-driven UI

Source: https://ui.praison.ai/docs/features/a2ui-canvas

# A2UI canvas — agent-driven UI

PraisonAIUI hosts **A2UI v0.9** surfaces: agents push structured UI messages to a live canvas while users chat in the same window or on a full-page workspace.

For dashboard extension patterns (views, plugins, layout JSON), see [Agent UI host](agent-ui-host.md).

## Quick start

```python
import praisonaiui as aiui

aiui.set_style("dashboard")
aiui.set_chat_preview(enabled=True, surface_id="main", width="38%")
aiui.set_pages(["chat-canvas", "chat", "canvas"])

@aiui.page("agent-canvas", title="Agent Canvas", icon="🖼️")
async def agent_canvas():
    return {"_surface": {"id": "main", "messages": []}}

@aiui.surface_action("main")
async def on_surface_action(action: dict):
    return {"received": action}
```

Run the full example: [`examples/python/30-a2ui-canvas/app.py`](../../examples/python/30-a2ui-canvas/app.py).

## Dashboard pages

| Page id | Route | Purpose |
|---------|-------|---------|
| `chat-canvas` | `/chat-canvas` | Split view — chat left, live A2UI preview right |
| `chat` | `/chat` | Vanilla chat (unchanged) |
| `canvas` | `/canvas` | Full-page surface workspace |

Enable the split preview with [`set_chat_preview`](../api/python.md#set_chat_previewenabled-surface_id-width). Settings appear in `/ui-config.json` as `chat.preview: { enabled, surfaceId, width }`.

## Agent integration

Agents should call **`send_a2ui_messages`** (from `praisonaiagents.tools.a2ui_tools`) with A2UI message dicts:

```python
send_a2ui_messages(messages=[
    {"createSurface": {"surfaceId": "main", "catalogId": "basic"}},
    {"updateComponents": {"components": [
        {"component": "Text", "text": {"literal": "Hello"}},
        {"component": "Button", "text": {"literal": "Submit"},
         "action": {"name": "handleSubmit"}},
    ]}},
])
```

Wrap the tool with **`coerce_a2ui_tool_messages`** so common LLM argument shapes still work:

```python
from praisonaiui.a2ui_utils import coerce_a2ui_tool_messages

@tool
def send_a2ui_messages(messages):
    coerced = coerce_a2ui_tool_messages(messages, surface_id="main")
    return sdk_send_a2ui(messages=coerced)
```

`coerce_a2ui_tool_messages` accepts:

- A JSON string or list of message dicts
- A dict with a `messages` key
- A bare `components` list (wrapped in `updateComponents`)
- A single component dict (wrapped in `updateComponents`)
- Missing `createSurface` (inserted automatically for the given `surface_id`)

Tool results are detected by [`a2ui_utils`](../../src/praisonaiui/a2ui_utils.py) and ingested into the surface store; connected clients receive WebSocket `a2ui_surface` events.

## HTTP API

| Method | Path | Behaviour |
|--------|------|-----------|
| `GET` | `/api/surfaces` | List surfaces and message counts |
| `GET` | `/api/surfaces/{id}` | Surface state; **200 with `{ messages: [] }`** if not created yet (empty canvas is normal) |
| `POST` | `/api/surfaces/{id}/messages` | Append or replace messages (`replace: true` in body) |
| `POST` | `/api/surfaces/{id}/actions` | User action from a button/component |
| `DELETE` | `/api/surfaces/{id}` | Clear surface |

Realtime updates use the existing dashboard WebSocket (`a2ui_surface` payload).

## CLI

Manage surfaces against a running server (`--server` / `AIUI_SERVER`, default `http://127.0.0.1:8000`):

```bash
aiui surface list
aiui surface get main
aiui surface get main --json
aiui surface push main --file messages.json
aiui surface push main --file messages.json --replace
aiui surface clear main
aiui surface status
```

`messages.json` must contain `{ "messages": [ ... ] }`.

## Frontend modules

Shared dashboard JS (lazy-loaded with `chat-canvas`):

| Module | Role |
|--------|------|
| `surface-utils.js` | Load surface, WebSocket sync, post actions |
| `canvas-preview.js` | Right-hand preview panel |
| `a2ui-mapper.js` | Default DOM mapper (Text, Button, Column, Row, Card, …) |
| `plugins/views/chat-canvas.js` | Composes chat + preview without modifying `chat.js` |

Override rendering: `window.aiui.registerSurfaceRenderer("main", fn)`.

## Troubleshooting

| Symptom | Likely cause | Fix |
|---------|--------------|-----|
| Chat works but canvas stays empty | Agent did not call `send_a2ui_messages` | Strengthen instructions; wrap tool with `coerce_a2ui_tool_messages` |
| Tool error / invalid JSON | LLM passed wrong shape | Use coercion wrapper; include schema prompt from `praisonaiagents.ui.a2ui.adapter` |
| Preview shows raw JSON | Component type not in `a2ui-mapper` | Extend mapper or use supported components |
| `GET /api/surfaces/main` empty | Normal before first push | Push via agent or `aiui surface push` |
| Button click does nothing | No `@aiui.surface_action` handler | Register handler for that `surface_id` |

# Agent UI host — modular dashboard shell

# Agent UI host — modular dashboard shell

PraisonAIUI can host any AI agent backend behind a **modular dashboard shell**: pages, views, layout components, optional plugins, and branding — without forking the frontend.

## Architecture

```text
YAML / Python config → server (pages API, plugins.json) → dashboard.js shell
                              ↓
         registerView / BUILTIN_VIEWS / layout JSON / registerComponent
                              ↓
                    renderComponent() + theme (--db-*)
```

**Extension priority** (first match wins):

1. `window.aiui.registerView(pageId, …)`
2. Dashboard manifest plugins (`dashboard-plugins/*/manifest.json`)
3. Built-in view modules (`plugins/views/*.js` via `BUILTIN_VIEWS`)
4. Server `aiui.layout()` JSON from `@aiui.page()`
5. `window.aiui.registerComponent(type, …)` inside `renderComponent`
6. Generic JSON fallback viewer

## Video Studio

For YAML scene authoring with an external PraisonAI Video engine, see [Video Studio](video-studio.md).

## Quick start (external agent)

```python
import praisonaiui as aiui
from praisonaiui.server import create_app

aiui.set_style("dashboard")
aiui.set_branding(title="Acme Agents", logo="A")
aiui.set_pages(["chat", "tasks", "sessions", "config"])
aiui.set_dashboard(modules=["jobs"], sidebar=True, page_header=True)

@aiui.page("tasks", title="Tasks", icon="📋", group="Work")
async def tasks_page():
    return aiui.layout([
        aiui.board(columns=[
            {"id": "todo", "title": "Todo", "cards": [aiui.card("Review PR", footer="agent-a")]},
            {"id": "done", "title": "Done", "cards": [aiui.card("Ship feature")]},
        ]),
    ])

app = create_app()
```

See [`examples/python/external-agent-dashboard/app.py`](../../examples/python/external-agent-dashboard/app.py).

## `window.aiui` extension API

| API | Purpose |
|-----|---------|
| `version` | Shell protocol version (`'1'`) |
| `registerView(pageId, renderFn, cleanup?)` | Replace or add a full page renderer |
| `registerComponent(type, renderFn)` | Override a layout component type |
| `registerSurfaceRenderer(surfaceId, renderFn)` | Custom A2UI surface renderer |
| `selectPage(pageId)` | Navigate programmatically (e.g. open full canvas) |
| `registerSlot(name, renderFn)` | Inject DOM into named slots |
| `sdk.fetchJSON(url, opts?)` | Authenticated fetch helper |
| `sdk.el(tag, attrs?, children?)` | Small DOM builder |
| `sdk.themeVar('--db-*', fallback?)` | Read theme CSS variables |
| `sdk.createBoard(root, { fetch, pollMs? })` | Live board with optional polling |

### Slots

| Slot id | Where it renders |
|---------|------------------|
| `shell:sidebar:footer` | Bottom of sidebar (default: health hint) |
| `page:{pageId}:toolbar` | Right side of page header |

Register only what you need; omit slots you do not use.

## Layout components (Python → JS)

Define pages with `@aiui.page()` returning `aiui.layout([...])`. Types are implemented once in [`ui.py`](../../src/praisonaiui/ui.py) and [`dashboard.js`](../../src/praisonaiui/templates/frontend/plugins/dashboard.js).

**Kanban / board:** use `aiui.board(columns=[...])`. Columns contain `id`, `title`, and `cards` (from `aiui.card()` or dicts). The shell renders via `renderBoard`, composing existing card renderers (DRY).

## A2UI surfaces (agent-driven UI)

Three tiers work together:

| Tier | Mechanism | Use case |
|------|-----------|----------|
| Dashboard | `aiui.layout()` → `_components` | Python-authored pages |
| A2UI | `send_a2ui_messages` → `SurfaceHost` | Agent-generated UI in chat/canvas |
| AG-UI | `POST /agui` SSE | CopilotKit / external clients |

Register an empty canvas page:

```python
@aiui.page("agent-canvas", title="Agent Canvas", icon="🖼️")
async def agent_canvas():
    return {"_surface": {"id": "main", "messages": []}}
```

Or use `@aiui.surface_action("main")` for button callbacks.

**Full guide:** [A2UI canvas](a2ui-canvas.md) — chat-canvas split view, `send_a2ui_messages`, HTTP/CLI, `coerce_a2ui_tool_messages`, troubleshooting. Example: [`examples/python/30-a2ui-canvas/`](../../examples/python/30-a2ui-canvas/app.py).

## Optional dashboard modules

Load heavy built-ins only when listed:

```python
aiui.set_dashboard(modules=["jobs", "auth", "api"])
```

```yaml
dashboard:
  modules: [jobs]
```

This adds `jobs.js`, `auth.js`, or `api.js` to the plugin chain and maps them in `BUILTIN_VIEWS`. `feedback` is always available as a built-in view when the page is enabled.

## Third-party dashboard plugins

Place folders under:

- `~/.praisonai/dashboard-plugins/{name}/`
- Or `src/praisonaiui/templates/frontend/dashboard-plugins/{name}/` (shipped examples)

Each plugin needs `manifest.json` + `index.js` (optional `styles.css`):

```json
{
  "name": "my-board",
  "label": "My board",
  "icon": "📋",
  "tab": { "path": "/my-board" },
  "entry": "index.js"
}
```

The server exposes:

- `GET /api/dashboard/plugins` — manifest list
- `GET /dashboard-plugins/{name}/{path}` — static assets

Plugins register views in `index.js`:

```javascript
window.aiui.registerView('my-board', async (container) => {
  window.aiui.sdk.createBoard(container, {
    fetch: async () => ({ columns: [...] }),
  });
});
```

Sample: [`sample-board`](../../src/praisonaiui/templates/frontend/dashboard-plugins/sample-board/).

## Agent plugins vs dashboard plugins

| System | Location | Purpose |
|--------|----------|---------|
| Agent plugins | `~/.praisonai/plugins/` | Python agent extensions |
| Dashboard plugins | `~/.praisonai/dashboard-plugins/` | JS UI tabs |

See [PraisonAI package integration](praisonai-package-integration.md) for backend wiring, jobs API, and deployment.

## Granular control — opt-in / opt-out

| What you control | How | Example |
|------------------|-----|---------|
| UI mode | `aiui.set_style(...)` | `"dashboard"`, `"chat"`, `"docs"` |
| Sidebar pages | `aiui.set_pages([ids])` whitelist | `["chat", "sessions"]` |
| Hide built-ins | YAML `pages.disabled: [...]` | Blacklist in server |
| Sidebar on/off | `set_dashboard(sidebar=False)` | Chat-only full width |
| Page title bar | `set_dashboard(page_header=False)` | Cleaner surface |
| Optional modules | `set_dashboard(modules=[...])` | `["jobs"]` only |
| Third-party tabs | Install chosen `dashboard-plugins/` folders | Manifest per plugin |
| Shell chrome | `registerSlot` | Header/footer widgets |
| Look only | `set_theme`, `set_branding`, `set_custom_css` | White-label |
| Replace one page | `registerView(pageId, ...)` | Override built-in |
| Board UI | `aiui.board()` or plugin | Not in default nav |

**Note:** `@aiui.page()` custom pages are **not** filtered by `set_pages()` — only built-in dashboard pages are. Remove custom pages from code to hide them.

### Example profiles

```python
# Chat-only
aiui.set_style("dashboard")
aiui.set_pages(["chat"])
aiui.set_dashboard(sidebar=False, page_header=False)

# Ops console — no chat
aiui.set_pages(["sessions", "agents", "logs", "config", "usage", "approvals"])
```

```yaml
style: dashboard
pages:
  enabled: [chat, agents, memory, sessions]
dashboard:
  sidebar: true
  pageHeader: true
  modules: [jobs]
  plugin_dirs: [/opt/my-agent/plugins]
```

CLI: `aiui pages ids` lists built-in page ids for whitelists.

## DRY rules for contributors

1. Add new layout types in **`ui.py`** and one `case` in **`dashboard.js`**.
2. Page-specific UI belongs in **`plugins/views/*.js`**, delegating to shared modules (`jobs.js`, etc.) via thin wrappers.
3. Reuse **`_helpers.js`** (`pageToolbar`, `filterChips`, `searchInput`, `modalShell`, `toast`).
4. Boards compose **`card`** / **`columns`** — do not duplicate card markup in plugins.

# Chat Attachments

Source: https://ui.praison.ai/docs/features/attachments

# Chat Attachments

Upload files to include with chat messages — PDFs, CSVs, images, and text files up to 50 MB per file. Uploaded files are **automatically processed** and their content is injected into the agent's prompt.

![Attachments Panel](../images/attachments-panel.png)

## Quick Start

```bash
# 1. Upload a file
RESP=$(curl -s -X POST http://localhost:8083/api/chat/attachments \
  -F "file=@report.pdf" \
  -F "session_id=my-session")

# 2. Send chat with the attachment
ATT_ID=$(echo $RESP | python3 -c "import sys,json; print(json.load(sys.stdin)['id'])")
curl -X POST http://localhost:8083/api/chat/send \
  -H "Content-Type: application/json" \
  -d "{\"content\":\"Summarize this document\",\"session_id\":\"my-session\",\"attachment_ids\":[\"$ATT_ID\"]}"
```

The agent will receive the extracted PDF text prepended to the user message and can answer questions about the document's content.

## How It Works

    A["File Upload"] --> B["AttachmentManager"]

```

## File Processing by Type

When you send a chat message with `attachment_ids`, each attachment is processed based on its type:

| File Type | Processing | What the Agent Sees |
|-----------|-----------|-------------------|
| **PDF** (`.pdf`) | Text extracted via `pypdf` | Full text content prepended to prompt |
| **Images** (`.png`, `.jpg`, etc.) | Passed to SDK multimodal handler | Image sent as base64 to vision-capable LLMs |
| **Text/Code** (`.txt`, `.py`, `.csv`, etc.) | File contents read directly | Full file content prepended to prompt |

!!! note "PDF Dependency"
    PDF text extraction requires the `pypdf` package (`pip install pypdf`). If `pypdf` is not installed, a fallback message is shown instead of the extracted text. `pypdf` is included in PraisonAIUI's dependencies by default.

## Supported File Types

| Category | Extensions |
|----------|-----------|
| Documents | `.pdf`, `.doc`, `.docx`, `.txt`, `.md` |
| Data | `.csv`, `.json`, `.xml`, `.yaml`, `.yml` |
| Images | `.png`, `.jpg`, `.jpeg`, `.gif`, `.webp`, `.svg` |
| Code | `.py`, `.js`, `.ts`, `.html`, `.css` |

!!! warning "Blocked Types"
    Executable files (`.exe`, `.sh`, `.bat`, `.cmd`, `.com`) are rejected by default.

## Configuration

```python
from praisonaiui.features.attachments import AttachmentManager

# Custom limits
mgr = AttachmentManager(
    max_size_mb=100,          # Max file size in MB (default: 50)
    allowed_types={"text/*", "image/*", "application/pdf"},
)
```

## REST API

| Endpoint | Method | Description |
|----------|--------|-------------|
| `/api/chat/attachments` | POST | Upload a file |
| `/api/chat/attachments` | GET | List attachments for a session |
| `/api/chat/attachments/{id}` | DELETE | Delete an attachment |

### Upload

```bash
curl -X POST http://localhost:8083/api/chat/attachments \
  -F "file=@data.csv" \
  -F "session_id=abc-123"
```

Response:
```json
{
  "id": "att_a1b2c3d4",
  "filename": "data.csv",
  "content_type": "text/csv",
  "size": 34800,
  "session_id": "abc-123"
}
```

### Send Chat with Attachments

```bash
curl -X POST http://localhost:8083/api/chat/send \
  -H "Content-Type: application/json" \
  -d '{
    "content": "What does this document say?",
    "session_id": "abc-123",
    "attachment_ids": ["att_a1b2c3d4"]
  }'
```

The `attachment_ids` array links uploaded files to the chat message. The server extracts content from each attachment and prepends it to the user's message before sending to the agent.

### List

```bash
curl http://localhost:8083/api/chat/attachments?session_id=abc-123
```

## WebSocket

When sending messages via WebSocket, include `attachment_ids` in the message payload:

```json
{
  "type": "chat",
  "content": "Analyze this PDF",
  "session_id": "abc-123",
  "attachment_ids": ["att_a1b2c3d4"]
}
```

# Backend Integration Contract

Source: https://ui.praison.ai/docs/features/backend-integration

# Backend Integration Contract

PraisonAIUI supports a four-layer integration model so standalone mode and SDK-integrated mode can share the same feature APIs.

## Four Layers

1. **Feature API layer**  
   Endpoints live in feature modules and expose stable HTTP/CLI behaviour.
2. **Feature manager layer**  
   Each feature manager keeps local fallback logic for standalone operation.
3. **Backend factory layer**  
   `praisonaiui.backends` provides optional injected factories (`get_workflow_runner()`, `get_hooks_lister()`, `get_usage_query()`, etc.).
4. **SDK/runtime layer**  
   PraisonAI or praisonaiagents implementations are used when injected or importable.

## Injection Contract

- Injected backends are optional and must be callable.
- Features must keep local fallbacks when injected backends are absent or fail.
- Backend call signatures should remain minimal and dict/list based.
- Integration should not introduce hard imports in feature modules when a fallback already exists.

## Operational Rule

When integrated, wrappers should inject backend callables at startup; when standalone, features should run without any backend injection.

# BeautifulUI Integration Strategy

Source: https://ui.praison.ai/docs/features/beautifului-integration

# BeautifulUI Integration Strategy

> **Epic:** [#292](https://github.com/MervinPraison/PraisonAIUI/issues/292) — BeautifulUI integration strategy for AI-native dashboard UX.
> This is the durable, agreed strategy that the linked child issues execute against.

[BeautifulUI](https://www.beautifului.dev/) (MIT, Shane Levine / Turbo) is a **copy-paste / shadcn-registry** library of React primitives for AI-native interfaces: thinking traces, streaming answers with inline sources, HITL approval cards, tool chips, task rows, context chunks, diff/records tables, prompt bars, and a reference chat harness.

There is **no published npm package** named `beautiful-ui`. It ships only as source consumed via the shadcn registry or manual copy.

## 1. Strategic decision

BeautifulUI is adopted as **vendored source**, not a runtime dependency, and is exposed to dashboard plugins **only through the existing `@praisonaiui/react` package** — never by importing upstream file paths directly. Rollout is **phased behind a feature flag**, keeping the current vanilla dashboard as the fallback until parity is proven.

Upstream stack (Next.js 15 · React 19 · Tailwind v4 · TypeScript) is closely aligned with PraisonAIUI's `src/frontend` (Vite · React 19 · Tailwind v4 · shadcn/Radix), so primitives port with adapter work rather than a runtime bridge.

## 2. Pillars

| # | Pillar | Decision |
|---|--------|----------|
| 1 | **Vendoring model** | Add primitives into `src/frontend` via `npx shadcn add https://www.beautifului.dev/r/<component>.json`, or manual copy from [github.com/slev12397/beautiful-ui](https://github.com/slev12397/beautiful-ui). Pin via lockfile plus a recorded registry URL / git SHA. No `beautiful-ui` npm dependency in production builds. |
| 2 | **Adapter layer** | Map PraisonAIUI chat / approval / trace **protocol events** to stable internal props. Primitives sit behind `@praisonaiui/react` exports; dashboard plugins consume those exports, not upstream paths. See [#294](https://github.com/MervinPraison/PraisonAIUI/issues/294). |
| 3 | **Hybrid rollout** | Mount React **islands** (or expand `@praisonaiui/react`) for high-value surfaces first — chat streaming/thinking/tools, then approvals. Vanilla chat (`templates/frontend/plugins/views/chat.js`) stays as the flag-gated fallback until parity is proven. |
| 4 | **Token strategy** | Merge BeautifulUI foundation CSS **selectively** into the existing shadcn theme generation (`praisonaiui/themes.py`). One design system per page — avoid two competing token sets. |
| 5 | **Icon licence** | Upstream `SidebarNav` uses the paid `@central-icons-react`. Port nav patterns with **lucide-react** (already in PraisonAIUI) instead. |

## 3. Phasing

1. **Spike** — evaluate primitives in the dev environment, confirm React 19 / Tailwind v4 alignment. [#293](https://github.com/MervinPraison/PraisonAIUI/issues/293)
2. **Architecture** — adapter layer + upstream pin policy. [#294](https://github.com/MervinPraison/PraisonAIUI/issues/294)
3. **CI gate** — frontend build + BeautifulUI compatibility check (no frontend build gate exists today). [#295](https://github.com/MervinPraison/PraisonAIUI/issues/295)
4. **Migrations** — chat streaming / thinking / tool chips ([#296](https://github.com/MervinPraison/PraisonAIUI/issues/296)), then the approval card ([#297](https://github.com/MervinPraison/PraisonAIUI/issues/297)).
5. **Docs** — upgrade playbook + MIT attribution. [#298](https://github.com/MervinPraison/PraisonAIUI/issues/298)

## 4. Risks

| Risk | Mitigation |
|------|------------|
| No semver npm package | Vendor the source; pin to a recorded registry URL / git SHA in the lockfile. |
| Upstream breaking registry JSON | Vendoring decouples builds from live registry; re-sync is a deliberate, reviewed step. |
| Icon licence (`@central-icons-react` is paid) | Use lucide-react for ported nav patterns; never vendor the paid package. |
| Two competing design systems on one page | Selective CSS token merge into `themes.py`; adapter-only prop surface. |
| React / Tailwind drift | Upstream (React 19 / Tailwind v4) already matches `src/frontend`; the CI gate catches drift. |

## 5. Out of scope

- Replacing the entire dashboard shell in one PR.
- PyPI packaging of BeautifulUI.
- iframe embedding of beautifului.dev.
- Depending on any unpublished npm package for production builds.

## 6. Acceptance criteria status

- [x] Written integration strategy agreed (vendoring + adapter + phased rollout) — this document.
- [x] Risks documented — section 4.
- [x] Child issues filed and prioritised — [#293](https://github.com/MervinPraison/PraisonAIUI/issues/293)–[#298](https://github.com/MervinPraison/PraisonAIUI/issues/298).
- [x] No requirement to depend on unpublished npm packages for production builds — pillar 1, out of scope.

# Browser Automation

Source: https://ui.praison.ai/docs/features/browser-automation

# Browser Automation

Expose **browser agent capabilities** (CDP, Playwright) through the dashboard — run browser tasks from the UI.

## Quick Start

```bash
# Check browser automation status
curl http://localhost:8083/api/browser/status

# Run a browser task
curl -X POST http://localhost:8083/api/browser/run \
  -H "Content-Type: application/json" \
  -d '{"task": "Go to example.com and extract the page title", "url": "https://example.com"}'
```

## How It Works

```mermaid
graph TD
    A["Dashboard UI"] --> B["POST /api/browser/run"]
    B --> C["BrowserAutomationManager"]
    C --> D{"Backend Available?"}
    D -->|Playwright| E["Playwright Browser"]
    D -->|CDP| F["Chrome DevTools Protocol"]
    D -->|None| G["Error: Install praisonai[browser]"]
    E --> H["Execute Task"]
    F --> H
    H --> I["Return Result"]
```

## Prerequisites

Browser automation requires `praisonai[browser]`:

```bash
pip install praisonai[browser]
```

This installs the Playwright and/or CDP backends.

## Status

The status endpoint reports which backends are available:

```bash
curl http://localhost:8083/api/browser/status
```

```json
{
  "available": true,
  "tasks_run": 5,
  "backends": ["playwright", "cdp"]
}
```

## REST API

| Endpoint | Method | Description |
|----------|--------|-------------|
| `/api/browser/status` | GET | Check availability and stats |
| `/api/browser/run` | POST | Execute a browser task |

### Run Task

```bash
curl -X POST http://localhost:8083/api/browser/run \
  -H "Content-Type: application/json" \
  -d '{
    "task": "Search for PraisonAI on Google",
    "url": "https://google.com"
  }'
```

```json
{
  "status": "completed",
  "result": "Found 10 results for PraisonAI..."
}
```

# Channel-to-Chat Bridge

Source: https://ui.praison.ai/docs/features/channel-chat-bridge

# Channel-to-Chat Bridge

Bridge channel bot conversations (Slack, Discord, Telegram) into the Chat UI in real-time.

## Architecture

```mermaid
sequenceDiagram
    participant PU as Platform User
    participant Bot as SlackBot / DiscordBot / TelegramBot
    participant Bridge as _attach_chat_bridge()
    participant CM as ChatManager.broadcast()
    participant WS as Chat WebSocket (/api/chat/ws)
    participant UI as chat.js (Chat View)

    Note over Bridge: Attached BEFORE bot.start()
    Note over Bridge: All broadcasts via asyncio.create_task<br/>(fire-and-forget, zero perf impact)

    PU->>Bot: "Hello" (platform message)
    Bot->>Bridge: on_message hook fires
    Bridge->>CM: broadcast({type: "channel_message", ...})
    CM->>WS: send to connected clients
    WS->>UI: _handleChannelMessage() renders with platform badge

    Bot->>Bot: agent processes message
    Bot->>Bridge: _wrapped_chat() returns response
    Bridge->>CM: broadcast({type: "channel_response", ...})
    CM->>WS: send to connected clients
    WS->>UI: _handleChannelResponse() renders as assistant
```

## How It Works

### Backend (`channels.py`)

`_attach_chat_bridge(channel_id, bot, platform)` is called in `_start_channel_bot()` right before the bot task is launched:

1. **`on_message` hook** — Captures incoming platform messages and broadcasts `channel_message` events with sender name, platform, and icon
2. **`_session.chat()` wrapper** — Wraps the agent's chat method so responses are also broadcast as `channel_response` events
3. **Persistence** — All messages saved to the datastore under session `channel-{channel_id}` for history on reload

### Frontend (`chat.js`)

| Function | Purpose |
|---|---|
| `_handleChannelMessage(data)` | Renders incoming platform user messages; auto-switches to channel session if on fresh chat |
| `_handleChannelResponse(data)` | Renders agent responses from channel bots |
| `_appendChannelMsg(role, data)` | Creates message DOM with platform badge, icon, sender name |
| `_markSessionUnread(sessionId)` | Adds unread dot to sidebar for inactive channel sessions |

## Performance

Every broadcast is dispatched via `asyncio.create_task()` — the original bot message handling is **never blocked**. Errors in broadcasting are logged at `debug` level and swallowed — the bot continues normally even with zero Chat UI clients connected.

## Session Naming

Each channel gets a dedicated session: `channel-{channel_id}`. Platform icons:

| Platform | Icon |
|---|---|
| Slack | 💬 |
| Discord | 🎮 |
| Telegram | ✈️ |
| WhatsApp | 📱 |

## WebSocket Events

### `channel_message`

```json
{
  "type": "channel_message",
  "session_id": "channel-abc123",
  "channel_id": "abc123",
  "platform": "slack",
  "icon": "💬",
  "content": "Hello from Slack!",
  "sender": "john.doe",
  "timestamp": 1773033464.37
}
```

### `channel_response`

```json
{
  "type": "channel_response",
  "session_id": "channel-abc123",
  "channel_id": "abc123",
  "platform": "slack",
  "icon": "💬",
  "content": "Hi! How can I help?",
  "agent_name": "assistant",
  "timestamp": 1773033465.12
}
```

# Code Execution

Source: https://ui.praison.ai/docs/features/code-execution

# Code Execution

**Sandboxed code execution** with language allowlists and SDK integration. Wraps `praisonaiagents.tools.code.execute_code` when available, falls back to safe simulation mode.

## Quick Start

```bash
# List supported languages
curl http://localhost:8083/api/code/languages

# Execute code
curl -X POST http://localhost:8083/api/code/execute \
  -H "Content-Type: application/json" \
  -d '{"code":"print(\"Hello World\")","language":"python"}'
```

## How It Works

```mermaid
graph TD
    A["Code Submission"] --> B{"SandboxExecutionManager"}
    B --> C{"SDK Available?"}
    C -->|Yes| D["praisonaiagents\nexecute_code()"]
    C -->|No| E["Simulated Mode\n(safe, no execution)"]
    B --> F{"Language Allowed?"}
    F -->|No| G["400 Error\n+ allowed list"]
```

1. Code is submitted with a target language
2. The manager checks if the language is in the **allowlist** (default: python, javascript, bash)
3. If `praisonaiagents` is installed, delegates to `execute_code` for real execution
4. Otherwise returns a simulation response with the code size

## Configuration

```python
from praisonaiui.features.code_execution import SandboxExecutionManager, set_execution_manager

# Custom configuration
mgr = SandboxExecutionManager(
    sandbox=True,                              # Enable sandbox mode
    timeout=60,                                # Execution timeout
    allowed_languages=["python", "javascript"] # Only allow these languages
)
set_execution_manager(mgr)
```

## REST API

| Endpoint | Method | Description |
|----------|--------|-------------|
| `/api/code/languages` | GET | List supported languages |
| `/api/code/execute` | POST | Execute code in sandbox |

### POST /api/code/execute

```json
// Request
{"code": "print('hello')", "language": "python", "timeout": 30}

// Response (simulated mode)
{"language": "python", "status": "simulated",
 "output": "[Sandbox] Code received (15 chars, python)",
 "sandbox": true, "note": "Install praisonaiagents for real execution"}

// Response (disallowed language → 400)
{"status": "error", "error": "Language 'ruby' not allowed",
 "allowed": ["python", "bash", "javascript"]}
```

# Config Hot-Reload

Source: https://ui.praison.ai/docs/features/config-hot-reload

# Config Hot-Reload

Live configuration reloading — watch YAML config files for changes and apply updates **without restarting the server**.

## Quick Start

```bash
# Start the watcher
curl -X POST http://localhost:8083/api/config/watcher \
  -H "Content-Type: application/json" \
  -d '{"action": "start"}'

# Edit your YAML config file — changes apply automatically

# Check watcher status
curl http://localhost:8083/api/config/watcher
```

## How It Works

```mermaid
graph LR
    A["config.yaml"] --> B["ConfigWatcher"]
    B --> C{"File hash changed?"}
    C -->|Yes| D["Trigger callbacks"]
    C -->|No| E["Wait poll_interval"]
    D --> F["Reload configuration"]
    D --> G["Notify connected clients"]
    E --> C
```

1. **ConfigWatcher** polls the config file at a configurable interval (default: 2 seconds)
2. On each poll, it computes the file's SHA-256 hash
3. If the hash differs from the previous check, it triggers all registered reload callbacks
4. Callbacks can update feature settings, re-register agents, or reload themes

## Configuration

```python
from praisonaiui.features.config_hot_reload import ConfigWatcher

watcher = ConfigWatcher(
    config_path=Path("./config.yaml"),  # File to watch
    poll_interval=2.0,                   # Seconds between polls
)

# Register a callback
@watcher.on_reload
def handle_reload(new_config):
    print(f"Config reloaded: {new_config}")

# Start watching
watcher.start()
```

## REST API

| Endpoint | Method | Description |
|----------|--------|-------------|
| `/api/config/watcher` | GET | Get watcher status |
| `/api/config/watcher` | POST | Start/stop the watcher |
| `/api/config/reload` | POST | Force a manual reload |

### Watcher Status

```bash
curl http://localhost:8083/api/config/watcher
```

```json
{
  "watching": true,
  "config_path": "/path/to/config.yaml",
  "poll_interval": 2.0,
  "last_reload": 1709734400.0,
  "reload_count": 3
}
```

### Force Reload

```bash
curl -X POST http://localhost:8083/api/config/reload
```

# How the UI Looks Are Built

Source: https://ui.praison.ai/docs/features/css-architecture

# How the UI Looks Are Built

A beginner-friendly guide to how PraisonAIUI creates its visual appearance — what controls the colors, fonts, and layout you see on screen.

## The Big Picture

PraisonAIUI's appearance comes from **three layers** working together:

```
┌─────────────────────────────────────────┐
│ Layer 3: Your Config (YAML or Python)   │
│   theme preset / darkMode / radius /    │
│   custom CSS                            │
├─────────────────────────────────────────┤
│ Layer 2: Theme Engine                   │
│   Turns your config into CSS variables  │
│   (automatic, behind the scenes)        │
├─────────────────────────────────────────┤
│ Layer 1: CSS Foundation                 │
│   Tailwind CSS + shadcn/ui tokens       │
│   (built-in, you rarely touch this)     │
└─────────────────────────────────────────┘
```

**In plain English:**

1. You choose a theme preset (like "zinc" or "blue") in your config
2. The system translates that into CSS variables (color codes)
3. Every button, text, and background reads those variables to know what color to be

---

## Configuring from Python (`app.py`)

### Theme (colors, dark mode, radius)

```python
import praisonaiui as aiui

# Set the color palette, dark mode, and corner roundness
aiui.set_theme(preset="blue", dark_mode=True, radius="lg")
```

### Branding (title and logo)

```python
aiui.set_branding(title="MyApp", logo="🚀")
```

### Custom CSS (override any style)

```python
aiui.set_custom_css('''
    :root {
        --db-accent: #22c55e;          /* Change accent to green */
        --db-bg: #000000;              /* Pure black background */
        --db-sidebar-bg: #0a0a0a;      /* Darker sidebar */
    }
    .chat-msg-user .chat-msg-content {
        background: #22c55e;           /* Green user bubbles */
    }
''')
```

### Style (layout mode)

```python
aiui.set_style("dashboard")  # chat | agents | playground | dashboard | docs
```

### Complete Example

```python
import praisonaiui as aiui

# Appearance
aiui.set_theme(preset="emerald", dark_mode=True, radius="md")
aiui.set_branding(title="GreenBot", logo="🌿")

# Custom tweaks
aiui.set_custom_css('''
    .db-sidebar-header { font-size: 18px; }
''')

@aiui.reply
async def on_message(message):
    await aiui.say(f"Echo: {message}")
```

---

## Configuring from YAML

### Theme

```yaml
site:
  title: "MyApp"
  logo: "🚀"
  theme:
    preset: "blue"        # Color palette (22 options)
    darkMode: true         # true = dark, false = light
    radius: "lg"           # none | sm | md | lg | xl

style: dashboard
```

### Custom CSS

```yaml
site:
  title: "MyApp"
  customCss: |
    :root {
      --db-accent: #22c55e;
      --db-bg: #000000;
    }
    .chat-msg-user .chat-msg-content {
      background: #22c55e;
    }
```

---

## What You Can Control

### Theme Presets

The preset sets your **color palette** — it changes the accent color used for buttons, active states, and highlights across the entire UI.

| Category | Options |
|----------|---------|
| **Neutral** | zinc (default), slate, stone, gray, neutral |
| **Warm** | red, orange, amber, yellow |
| **Cool** | blue, indigo, violet, purple, cyan, sky, teal |
| **Nature** | green, emerald, lime |
| **Vibrant** | pink, rose, fuchsia |

### Dark Mode

```yaml
site:
  theme:
    darkMode: true      # true = dark background, false = light
```

When light mode is on, all backgrounds flip to white/light gray and text becomes dark.

### Border Radius

| Value | Effect |
|-------|--------|
| `none` | Sharp, square corners |
| `sm` | Slightly rounded |
| `md` | Medium rounded (default) |
| `lg` | More rounded |
| `xl` | Very rounded, pill-shaped buttons |

### Dashboard CSS Variables

For fine-grained control, override these variables in `customCss`:

| Variable | Default (dark) | What It Controls |
|----------|---------------|-----------------|
| `--db-bg` | `#0a0a0f` | Page background |
| `--db-sidebar-bg` | `#111118` | Sidebar background |
| `--db-accent` | `#6366f1` | Buttons, active items, highlights |
| `--db-text` | `#e4e4e7` | Primary text |
| `--db-text-dim` | `#71717a` | Secondary/muted text |
| `--db-border` | `rgba(255,255,255,0.06)` | Borders and dividers |
| `--db-card-bg` | `rgba(255,255,255,0.03)` | Card backgrounds |
| `--db-radius` | `10px` | Corner roundness |

---

## Priority Order

When the same setting is defined in multiple places:

| Priority | Source | Example |
|----------|--------|---------|
| 1 (highest) | **CLI flag** | `--style chat` |
| 2 | **Python API** | `aiui.set_theme(preset="blue")` |
| 3 | **YAML config** | `site.theme.preset: blue` |
| 4 (lowest) | **Built-in defaults** | zinc, dark, md radius |

---

## Two Chat Systems Explained

PraisonAIUI includes **two different chat interfaces**. Understanding the difference helps you choose the right one and know what features to expect.

### React Chat — The Full-Featured Chat

**When it's active:** `style: chat`, `style: agents`, or `style: playground`

This is the **recommended chat** for most users. It's built with React and benefits from the full modern web stack.

**What you get:**

| Feature | How it works |
|---------|-------------|
| 🎨 **Your theme colors** | Automatically follows your `preset` and `darkMode` settings |
| 📋 **Copy code button** | Click to copy any code block — shows "✓ Copied" feedback |
| 🌈 **Syntax highlighting** | Code is color-coded by language (Python, JavaScript, etc.) |
| 📊 **Markdown tables** | Tables render as proper formatted tables |
| 🔤 **Rich typography** | Headers, bold, italic, lists — all beautifully styled |
| 📎 **File attachments** | Upload files to include as context |

### Dashboard Chat — The Admin Chat

**When it's active:** `style: dashboard`

This is a lighter chat built as a dashboard plugin. It's designed for quick admin interactions within the dashboard.

**What you get:**

| Feature | How it works |
|---------|-------------|
| 🎨 **Dashboard theme** | Uses the dashboard's color scheme (now follows your preset!) |
| 💬 **Basic markdown** | Bold, italic, headings, code blocks, links, lists |
| 🔧 **Tool call display** | Shows when the AI is using tools |
| 📋 **Session management** | Create, switch, and manage conversations |
| 🤖 **Agent selection** | Pick which AI agent to chat with |

**What it doesn't have (yet):**

- ❌ Copy button on code blocks
- ❌ Syntax highlighting (code blocks are plain text)
- ❌ Markdown tables

### Which Should I Use?

| If you want... | Use this style |
|----------------|---------------|
| Best chat experience with all features | `style: chat` |
| Multi-agent dashboard with admin controls | `style: dashboard` |
| Agent profiles and switching | `style: agents` |
| Side-by-side prompt testing | `style: playground` |

---

## File Map

Where does each piece of styling live?

| File | What It Does |
|------|-------------|
| `src/frontend/src/index.css` | Main CSS — imports Tailwind, defines default color variables |
| `src/frontend/src/themes.ts` | Theme engine — translates preset names to CSS variable values |
| `src/frontend/src/chat/ChatMessages.tsx` | React chat — has copy buttons, syntax highlighting |
| `templates/frontend/plugins/views/chat.js` | Dashboard chat — basic markdown, dashboard theme |
| `templates/frontend/plugins/dashboard.js` | Dashboard — defines `--db-*` color variables + reads config |

# Dark Mode

Source: https://ui.praison.ai/docs/features/dark-mode

# Dark Mode

Enable and customize dark mode for your site.

## Configuration

Enable dark mode in your configuration:

```yaml
site:
  theme:
    darkMode: true
```

## How It Works

When `darkMode: true`, the runtime:

1. Checks user's system preference (`prefers-color-scheme`)
2. Adds a toggle button to the Header component
3. Persists user preference in localStorage
4. Applies `data-theme="dark"` to the HTML element

## CSS Variables

Override dark mode colors in your CSS:

```css
[data-theme="dark"] {
  --md-default-bg-color: #0f172a;
  --md-default-fg-color: #f1f5f9;
  --md-primary-fg-color: #14B8A6;
}
```

## Manual Control

Control dark mode via the TypeScript SDK:

```typescript
import { useTheme } from 'praisonaiui/runtime';

function ThemeToggle() {
  const { theme, setTheme } = useTheme();
  
  return (
    <button onClick={() => setTheme(theme === 'dark' ? 'light' : 'dark')}>
      Toggle Theme
    </button>
  );
}
```

## Automatic Detection

The runtime automatically detects system preference:

```typescript
const prefersDark = window.matchMedia('(prefers-color-scheme: dark)').matches;
```

---

# Dashboard

Source: https://ui.praison.ai/docs/features/dashboard

# Dashboard

Build rich admin panels with **zero HTML/CSS/JS**. Register pages from Python, compose UIs with the component API, and the SDK renders everything.

## Quick Start

```python
import praisonaiui as aiui
from praisonaiui.server import create_app

aiui.set_style("dashboard")

@aiui.page("analytics", title="Analytics", icon="📊")
async def analytics():
    return aiui.layout([
        aiui.columns([
            aiui.card("Users", value=142, footer="+12% this week"),
            aiui.card("Revenue", value="$1,500"),
        ]),
        aiui.table(
            headers=["Agent", "Tasks", "Status"],
            rows=[["Researcher", 15, "Active"]],
        ),
    ])

app = create_app()
```

```bash
aiui run app.py
# → Dashboard with sidebar, "Analytics" page with cards + table
```

## How It Works

```mermaid
graph LR
    A["@aiui.page()"] --> B["/api/pages"]
    B --> C["dashboard.js"]
    C --> D["Sidebar + Pages"]
    E["aiui.layout()"] --> F["/api/pages/{id}/data"]
    F --> C
    C --> G["Cards / Tables / Charts"]
```

1. **`@aiui.page()`** registers a page with the server
2. **`dashboard.js`** fetches `/api/pages`, builds the sidebar automatically
3. When a page is selected, it fetches `/api/pages/{id}/data`
4. If the data contains `_components`, they render as real UI elements (cards, tables, etc.)

## Registering Pages

### Basic Page

```python
@aiui.page("status", title="Status", icon="🟢")
async def status_page():
    return {"status": "healthy", "uptime": "99.9%"}
```

Pages without component layouts render as formatted JSON.

### Page with Components

```python
@aiui.page("metrics", title="Metrics", icon="📈", group="Monitoring")
async def metrics_page():
    return aiui.layout([
        aiui.columns([
            aiui.card("CPU", value="12%"),
            aiui.card("Memory", value="324 MB"),
            aiui.card("Disk", value="45 GB free"),
        ]),
        aiui.text("Last updated: 30 seconds ago"),
    ])
```

### Page Groups

Pages are grouped in the sidebar by the `group` parameter:

```python
@aiui.page("agents", title="Agents", icon="🤖", group="Agent")
@aiui.page("config", title="Config", icon="⚙️", group="Settings")
@aiui.page("logs",   title="Logs",   icon="📜", group="Settings")
```

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `page_id` | `str` | ✅ | Unique identifier (URL-safe) |
| `title` | `str` | ✅ | Display name in sidebar |
| `icon` | `str` | ❌ | Emoji or icon character |
| `group` | `str` | ❌ | Sidebar group name |
| `description` | `str` | ❌ | Subtitle below the title |

## Component API

Build dashboard UIs entirely from Python — no HTML needed. **54 components** are available across 7 categories.

> See the full [Component API Reference](../api/components.md) for all components and parameters.

### Cards & Metrics

```python
# Simple cards
aiui.card("Total Users", value=142, footer="+12% this week")

# Metric cards with delta indicators
aiui.metric("Requests", value="12.3k", delta="+15%")
aiui.metric("Errors", value=23, delta="+3", delta_color="inverse")
```

### Columns

Arrange components side-by-side in a responsive grid:

```python
aiui.columns([
    aiui.card("Users", value=42),
    aiui.card("Tasks", value=18),
    aiui.card("Uptime", value="99.9%"),
])
```

### Tables

Data tables with headers and rows:

```python
aiui.table(
    headers=["Name", "Role", "Status"],
    rows=[
        ["Alice", "Engineer", "Active"],
        ["Bob", "Designer", "Idle"],
    ],
)
```

### Tabs & Accordion

Organize content in tabs or collapsible sections:

```python
aiui.tabs([
    {"label": "Overview", "children": [aiui.text("Tab 1")]},
    {"label": "Details",  "children": [aiui.table(headers=["K","V"], rows=[["a","b"]])]},
])

aiui.accordion([
    {"title": "FAQ", "content": "Answer here"},
])
```

### Alerts & Badges

```python
aiui.alert("Deploy complete!", variant="success", title="Done")
aiui.badge("New")
aiui.progress_bar("Upload", value=73)
```

### Text & Code

```python
aiui.text("Simple text block.")
aiui.markdown_text("**Bold** and `code`.")
aiui.code_block("print('hello')", language="python")
aiui.json_view({"key": "value"})
```

### Form Inputs

```python
aiui.text_input("Name", placeholder="Enter name")
aiui.select_input("Country", options=["USA", "UK", "Canada"])
aiui.slider_input("Volume", value=65, min_val=0, max_val=100)
aiui.checkbox_input("I agree", checked=True)
aiui.switch_input("Enable notifications")
aiui.radio_input("Language", options=["Python", "JS", "Go"])
```

### Charts

```python
aiui.chart("Revenue Over Time", data=[
    {"month": "Jan", "value": 1200},
    {"month": "Feb", "value": 1800},
], chart_type="line")
```

### Layout

Wrap all components in a layout container:

```python
aiui.layout([
    aiui.columns([...]),
    aiui.table(...),
    aiui.text("Footer note"),
])
```

The `layout()` function adds the `_components` key that tells the frontend to render structured components instead of raw JSON.


## Built-in Pages

When style is set to `dashboard`, **16 built-in pages** are auto-registered from the feature system:

| Page | Group | Description |
|------|-------|-------------|
| 🤖 Agents | Agent | Configured AI agents |
| ⚡ Skills | Agent | Agent tools and skills |
| 🖥️ Nodes | Agent | Execution nodes |
| 📊 Overview | Control | System overview |
| 📡 Channels | Control | Messaging channels |
| 📋 Sessions | Control | Active sessions |
| 📻 Instances | Control | Connected instances |
| 📈 Usage | Control | Token usage analytics |
| ⏰ Cron | Control | Scheduled jobs |
| 📋 Jobs | Control | Async job queue |
| ✅ Approvals | Control | Pending approvals |
| 🔌 API | Control | API documentation |
| ⚙️ Config | Settings | Runtime configuration |
| 🔐 Auth | Settings | Authentication |
| 📜 Logs | Settings | Real-time log viewer |
| 🐛 Debug | Settings | Debug information |

Custom pages added via `@aiui.page()` appear alongside built-in pages.

## Agent Run Button

Each agent card on the **Agents** page includes a **▶ Run** button. Clicking it navigates to the **Chat** page with that agent automatically pre-selected in the agent dropdown.

### How It Works

```mermaid
sequenceDiagram
    participant U as User
    participant A as Agents View
    participant D as Dashboard
    participant C as Chat View

    U->>A: Click "▶ Run" on agent card
    A->>D: pushState('/chat?agent=X')
    A->>D: dispatch popstate
    D->>C: selectPage('chat') → render()
    C->>C: loadAgents() → populate dropdown
    C->>C: Read ?agent=X → pre-select agent
    C->>C: replaceState('/chat') → clean URL
```

1. The Run button reads the agent name from its `data-id` attribute
2. It pushes `/chat?agent=<name>` to browser history and dispatches `popstate`
3. The dashboard's `popstate` listener calls `selectPage('chat')`, loading the Chat view
4. Chat's `render()` calls `loadAgents()`, then checks `URLSearchParams` for `?agent=`
5. If found, it sets the dropdown value and `currentAgentName`, then cleans the URL

## Test Panel

Every dashboard includes a **Test All Features** link at the bottom of the sidebar. It auto-discovers all registered features from `/api/features` and tests each endpoint, showing pass/fail results in a grid.

## Full Example

```python
import praisonaiui as aiui
from praisonaiui.server import create_app

aiui.set_style("dashboard")

@aiui.page("analytics", title="Analytics", icon="📊", group="Custom")
async def analytics():
    return aiui.layout([
        aiui.columns([
            aiui.card("Total Users", value=142, footer="+12% this week"),
            aiui.card("API Calls", value="3,847", footer="Last 24h"),
            aiui.card("Avg Latency", value="47ms", footer="-5ms"),
            aiui.card("Success Rate", value="99.2%", footer="✓ Healthy"),
        ]),

## API Endpoints

| Endpoint | Method | Description |
|----------|--------|-------------|
| `/api/pages` | GET | List all registered pages |
| `/api/pages/{id}/data` | GET | Get page handler response |
| `/api/features` | GET | List all registered features |
| `/plugins/plugins.json` | GET | Style-aware frontend plugin list |

---

## Client-Side Extension API

The dashboard provides a JavaScript API for registering custom views from the client side.

### `window.aiui.registerView(pageId, renderFn, cleanupFn)`

Register a custom view renderer for a page ID.

| Parameter | Type | Description |
|-----------|------|-------------|
| `pageId` | `string` | Page ID to handle (e.g. `"my-custom-page"`) |
| `renderFn` | `async (container: HTMLElement) => void` | Async function that renders into the container |
| `cleanupFn` | `() => void` | Optional cleanup function called when navigating away |

```javascript
// Register a custom view
window.aiui.registerView('my-analytics', async (container) => {
    const data = await fetch('/api/my-data').then(r => r.json());
    container.innerHTML = `
        <div class="db-card">
            <div class="db-card-title">Custom Analytics</div>
            <div class="db-card-value">${data.total}</div>
        </div>
    `;
}, () => {
    // Cleanup (optional) — called when user navigates away
    console.log('Cleaning up my-analytics view');
});
```

### View Resolution Priority

When a page is selected, the dashboard resolves views in this order:

1. **Custom registered views** — `window.aiui.registerView()` (highest priority)
2. **Built-in view modules** — Dynamic import from `/plugins/views/*.js`
3. **Generic JSON viewer** — Falls back to rendering `_components` or raw JSON

### `window.aiui.views`

Access the view registry directly:

```javascript
// Check if a view is registered
if (window.aiui.views['my-page']) {
    console.log('my-page view is registered');
}

// List all registered views
console.log(Object.keys(window.aiui.views));
```

### Built-in Views

The dashboard includes 22 built-in view modules:

| Page ID | View Module | Description |
|---------|-------------|-------------|
| `chat` | `chat.js` | Chat interface |
| `overview` | `overview.js` | Dashboard overview |
| `agents` | `agents.js` | Agent management |
| `sessions` | `sessions.js` | Session management |
| `memory` | `memory.js` | Memory viewer |
| `knowledge` | `knowledge.js` | Knowledge base |
| `logs` | `logs.js` | Real-time logs |
| `schedules` | `schedules.js` | Scheduled jobs |
| `config` | `config.js` | Runtime config |
| `approvals` | `approvals.js` | Tool approvals |
| `usage` | `usage.js` | Token usage |
| `channels` | `channels.js` | Messaging channels |
| `skills` | `skills.js` | Agent skills |
| `nodes` | `nodes.js` | Execution nodes |
| `guardrails` | `guardrails.js` | Safety guardrails |

# Deployment Guide

Production deployment guide for AIUI — covering Docker, environment variables, configuration, and security.

## Quick Start (Docker)

### Build the Image

```bash
cd /path/to/PraisonAIUI
docker build -t aiui:latest .
```

### Run with Default Settings

```bash
docker run -d \
  --name aiui \
  -p 8082:8082 \
  -e OPENAI_API_KEY=sk-... \
  aiui:latest
```

### Run with Custom Data Directory

```bash
docker run -d \
  --name aiui \
  -p 8082:8082 \
  -v /path/to/data:/data \
  -e AIUI_DATA_DIR=/data \
  -e OPENAI_API_KEY=sk-... \
  aiui:latest
```

### Docker Compose Example

```yaml
version: '3.8'
services:
  aiui:
    build: .
    ports:
      - "8082:8082"
    environment:
      - OPENAI_API_KEY=${OPENAI_API_KEY}
      - AIUI_DATA_DIR=/data
      - AUTH_ENFORCE=true
    volumes:
      - aiui-data:/data
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:8082/health/live"]
      interval: 30s
      timeout: 5s
      retries: 3

volumes:
  aiui-data:
```

## Environment Variables

| Variable | Default | Description |
|----------|---------|-------------|
| `AIUI_DATA_DIR` | `~/.praisonaiui` | Data directory for config, sessions, logs |
| `AIUI_PORT` | `8082` | Server port (Docker only) |
| `AIUI_HOST` | `0.0.0.0` | Server bind address (Docker only) |
| `AUTH_ENFORCE` | `false` | Enforce Bearer token auth on `/api/*` routes |
| `OPENAI_API_KEY` | — | OpenAI API key for LLM provider |

### Auth Enforcement

When `AUTH_ENFORCE=true`, all `/api/*` routes require a valid Bearer token in the `Authorization` header:

```bash
# Without AUTH_ENFORCE (default): open access
curl http://localhost:8082/api/config

# With AUTH_ENFORCE=true: requires auth
curl -H "Authorization: Bearer <api-key>" http://localhost:8082/api/config
```

**Exempt paths** (always accessible without auth):
- `/health`, `/health/live`, `/health/ready`, `/api/health` — health checks
- `/api/auth/login`, `/login` — login endpoints
- `/api/protocol`, `/api/protocol/negotiate` — protocol discovery

## Configuration

### Config File Location

The config file is located at `AIUI_DATA_DIR/config.yaml` (default: `~/.praisonaiui/config.yaml`).

### Config Structure

```yaml
schemaVersion: 2

# Site customization
site:
  title: "My Custom UI"  # Appears in HTML <title> and UI header

# Server settings
server:
  host: "127.0.0.1"
  port: 8003

# AI Provider
provider:
  name: "openai"
  model: "gpt-4o-mini"

# Gateway settings
gateway:
  host: "127.0.0.1"
  port: 8765

# Agents (managed via /api/agents)
agents: {}

# Skills (managed via /api/skills)
skills:
  enabled: []
  custom: {}

# Channels (managed via /api/channels)
channels: {}
```

### Site Title Customization

The site title is configurable via `site.title` in config.yaml:

```yaml
site:
  title: "AIUI"  # Default
```

This affects:
- HTML `<title>` tag
- Dashboard header
- `/ui-config.json` response

## Health Monitoring

### Health Endpoint

```bash
# Fast liveness probe (<500ms) - use for load balancers and K8s livenessProbe
curl http://localhost:8082/health/live
# Returns: {"status": "ok", "timestamp": "2024-..."}

# Readiness probe with parallel feature checks - use for K8s readinessProbe
curl http://localhost:8082/health/ready

# Deep diagnostics (parallel feature checks, deep by default)
curl http://localhost:8082/health
# Pass ?deep=false for an immediate liveness response
```

### Kubernetes Probes

Use the fast liveness endpoint for probes to avoid timeouts:

```yaml
livenessProbe:
  httpGet:
    path: /health/live
    port: 8082
  initialDelaySeconds: 10
  periodSeconds: 30
  timeoutSeconds: 1
readinessProbe:
  httpGet:
    path: /health/ready
    port: 8082
  initialDelaySeconds: 5
  periodSeconds: 10
```

### Docker HEALTHCHECK

The Dockerfile includes a built-in health check:

```dockerfile
HEALTHCHECK --interval=30s --timeout=5s --start-period=10s --retries=3 \
    CMD curl -f http://localhost:${AIUI_PORT}/health/live || exit 1
```

### CLI Health Commands

```bash
# Quick health check
aiui health-check --server http://localhost:8082

# Detailed per-feature health  
aiui health-check --server http://localhost:8082 --detailed

# Full diagnostic (7 checks)
aiui doctor --server http://localhost:8082
```

## Security

### Auth Modes

AIUI supports multiple authentication modes:

| Mode | Description |
|------|-------------|
| `none` | No authentication (default) |
| `api_key` | API key in `X-API-Key` header or `api_key` query param |
| `session` | Session token in `Authorization: Bearer <token>` header |
| `password` | Username/password login |

### API Key Management

```bash
# Create an API key (via CLI)
aiui auth create-key --name "my-app"

# Use the key
curl -H "X-API-Key: <key>" http://localhost:8082/api/config
```

### Network Considerations

- **Internal networks**: Use `AUTH_ENFORCE=false` if behind a trusted reverse proxy
- **Public exposure**: Always set `AUTH_ENFORCE=true` and use HTTPS
- **Load balancers**: Health check path is `/health/live` (fast, exempt from auth)

## Managed Hosting

### Required Endpoints

Hosting platforms should expose these endpoints:

| Endpoint | Purpose |
|----------|---------|
| `/health/live` | Fast liveness probe (returns `{"status": "ok"}`) |
| `/health/ready` | Readiness probe (parallel feature checks) |
| `/health` | Deep health (parallel feature checks; `?deep=false` for liveness) |
| `/api/protocol` | Protocol version and capabilities |
| `/api/protocol/negotiate` | Capability negotiation |
| `/api/features` | List of registered features |

### Protocol Discovery

```bash
# Get protocol version
curl http://localhost:8082/api/protocol
# Returns: {"version": "1.0", "capabilities": [...]}

# List features
curl http://localhost:8082/api/features
# Returns: {"features": [{"name": "chat", ...}, ...]}
```

### Minimum Viable Deployment

For a minimal AIUI deployment:

1. **Required**: `OPENAI_API_KEY` environment variable
2. **Recommended**: Persistent volume for `AIUI_DATA_DIR`
3. **Optional**: `AUTH_ENFORCE=true` for multi-tenant environments

```bash
docker run -d \
  -p 8082:8082 \
  -e OPENAI_API_KEY=sk-... \
  -v aiui-data:/root/.praisonaiui \
  aiui:latest
```

# Device Pairing

Source: https://ui.praison.ai/docs/features/device-pairing

# Device Pairing

Pair devices to sessions using **short hex codes** — scan and sync across mobile, tablet, and desktop.

## Quick Start

```bash
# Generate a pairing code
curl -X POST http://localhost:8083/api/pairing/create \
  -H "Content-Type: application/json" \
  -d '{"session_id":"my-session"}'

# Validate and pair (from the other device)
curl -X POST http://localhost:8083/api/pairing/validate \
  -H "Content-Type: application/json" \
  -d '{"code":"A1B2C3"}'

# List paired devices
curl http://localhost:8083/api/pairing/devices?session_id=my-session
```

## How It Works

```mermaid
sequenceDiagram
    participant Desktop
    participant Server
    participant Mobile
    
    Desktop->>Server: POST /api/pairing/create
    Server-->>Desktop: code: "723BE2" (5min TTL)
    Desktop->>Mobile: Show code on screen
    Mobile->>Server: POST /api/pairing/validate {"code":"723BE2"}
    Server-->>Mobile: valid: true, device_id, session_id
    Note over Desktop,Mobile: Both devices now share the same session
```

1. **Desktop** requests a pairing code for its session
2. Code is displayed on screen (6-char hex, 5-minute TTL)
3. **Mobile** enters the code to validate and pair
4. Server links the mobile device to the desktop's session
5. Both devices can now access the same conversation

### Security

- Codes are **single-use** — reusing returns `{"valid": false, "error": "Code already used"}`
- Codes **expire** after 5 minutes (configurable TTL)
- Max 5 devices per session (configurable)

## Configuration

```python
from praisonaiui.features.device_pairing import DefaultPairingManager, set_pairing_manager

mgr = DefaultPairingManager(
    code_ttl=600,       # 10-minute codes
    max_devices=10      # Allow more devices
)
set_pairing_manager(mgr)
```

## REST API

| Endpoint | Method | Description |
|----------|--------|-------------|
| `/api/pairing/create` | POST | Generate a pairing code |
| `/api/pairing/validate` | POST | Validate and consume a code |
| `/api/pairing/devices` | GET | List paired devices for session |
| `/api/pairing/devices/{id}` | DELETE | Remove a paired device |

### POST /api/pairing/create

```json
// Request
{"session_id": "my-session"}

// Response (201)
{"code": "723BE2", "session_id": "my-session",
 "created_at": 1772834103.42, "expires_at": 1772834403.42, "used": false}
```

### POST /api/pairing/validate

```json
// Request
{"code": "723BE2"}

// Response (valid)
{"valid": true, "device_id": "f408fdebd954d8da", "session_id": "my-session"}

// Response (reused → 400)
{"valid": false, "error": "Code already used"}
```

# What Makes PraisonAIUI Different

Source: https://ui.praison.ai/docs/features/differentiation

# What Makes PraisonAIUI Different

PraisonAIUI is a **protocol-driven UI framework** for building AI applications. This page explains how it differs from other popular tools.

## Quick Comparison

| Feature | PraisonAIUI | Streamlit | Gradio |
|---------|-------------|-----------|--------|
| **Architecture** | Protocol-driven (SDK→JSON→Client) | Script re-run | Input→Output |
| **UI Styles** | 6 (chat, agents, dashboard, playground, docs, custom) | 1 | 1 |
| **Components** | 48 structured | ~30 widgets | ~20 blocks |
| **Custom Pages** | `@aiui.page()` decorator | Multipage apps | Tabs |
| **Theme System** | 22 presets + custom CSS variables | Limited | Limited |
| **Agent-First** | ✅ Built for agents | ❌ General | ❌ ML demos |
| **Extensibility** | Plugin architecture | ❌ | ❌ |
| **YAML Config** | ✅ Full config | ❌ | ❌ |

---

## vs Streamlit

### How Streamlit Works

Streamlit re-runs your entire Python script on every interaction. The server renders HTML and sends it to the browser.

```python
# Streamlit
import streamlit as st

if st.button("Click me"):
    st.write("Clicked!")  # Entire script re-runs
```

### How PraisonAIUI Works

PraisonAIUI uses a **protocol-driven architecture**. Python functions return JSON dicts, which the client renders independently.

```python
# PraisonAIUI
import praisonaiui as aiui

@aiui.page("dashboard")
async def dashboard():
    return aiui.layout([
        aiui.card("Users", value=42),  # Returns JSON, client renders
    ])
```

### Key Differences

| Aspect | PraisonAIUI | Streamlit |
|--------|-------------|-----------|
| **Rendering** | Client-side from JSON | Server-side HTML |
| **State** | WebSocket + sessions | Script re-run |
| **Chat** | Real-time WebSocket streaming | Polling |
| **Extensibility** | `window.aiui.registerView()` | Limited |

**When to use PraisonAIUI**: Real-time chat, agent dashboards, multi-page admin panels, custom themes.

**When to use Streamlit**: Quick data apps, ML prototypes, simple dashboards.

---

## vs Gradio

### How Gradio Works

Gradio is designed for ML demos with an **input→output paradigm**. You define inputs, a function, and outputs.

```python
# Gradio
import gradio as gr

def greet(name):
    return f"Hello {name}!"

gr.Interface(fn=greet, inputs="text", outputs="text").launch()
```

### How PraisonAIUI Works

PraisonAIUI is designed for **conversational AI** with callbacks and structured components.

```python
# PraisonAIUI
import praisonaiui as aiui

@aiui.reply
async def on_message(message):
    await aiui.say(f"Hello {message.content}!")
```

### Key Differences

| Aspect | PraisonAIUI | Gradio |
|--------|-------------|--------|
| **Paradigm** | Conversational callbacks | Input→Output |
| **Components** | 48 structured (cards, tables, charts) | ~20 blocks |
| **Dashboard** | Full admin panel with pages | Tabs only |
| **Agent Support** | Built-in profiles, tools, memory | Manual |

**When to use PraisonAIUI**: Chat agents, admin dashboards, multi-agent systems.

**When to use Gradio**: ML model demos, quick input/output interfaces.

---

## Unique to PraisonAIUI

### 1. Protocol-Driven Architecture

Every feature implements a `FeatureProtocol` ABC with SDK-first fallback:

```
FeatureProtocol (ABC)
  ├── SDKFeatureManager  ← wraps praisonaiagents SDK
  └── SimpleFeatureManager  ← in-memory fallback
```

### 2. 48 Structured Components

Python functions return JSON dicts that the client renders:

```python
aiui.card("Revenue", value="$1,500", footer="+8%")
# → {"type": "card", "title": "Revenue", "value": "$1,500", "footer": "+8%"}
```

Components include: cards, tables, charts, forms, alerts, badges, tabs, accordions, and more.

### 3. 6 UI Styles

| Style | Use Case |
|-------|----------|
| `chat` | Conversational AI |
| `agents` | Multi-agent playground |
| `playground` | Prompt testing |
| `dashboard` | Admin panels |
| `docs` | Documentation sites |
| `custom` | Full control |

### 4. Client-Driven Plugin Architecture

Extend the dashboard with custom views:

```javascript
window.aiui.registerView('my-page', async (container) => {
    container.innerHTML = '<h1>Custom Page</h1>';
});
```

### 5. Theme System

22 Tailwind presets + custom CSS variables + dark/light mode:

```python
aiui.set_theme(preset="blue", dark_mode=True, radius="lg")
aiui.set_custom_css(":root { --db-accent: #22c55e; }")
aiui.register_theme("ocean", {"accent": "#0077b6"})
```

### 6. YAML + Python Dual Config

Same features configurable either way:

```yaml
# YAML
site:
  theme:
    preset: blue
    darkMode: true
```

```python
# Python
aiui.set_theme(preset="blue", dark_mode=True)
```

# Gap Analysis — Validated Against praisonai SDK

Source: https://ui.praison.ai/docs/features/gap-analysis

# Gap Analysis — Validated Against praisonai SDK

> **Last validated**: 2026-03-07 — All gaps resolved. 31 features, 128 tests pass.

## Executive Summary

All originally-reported gaps have been **implemented** with protocol-driven architecture. Each feature uses an ABC protocol with swappable manager implementations and lazy SDK imports for graceful degradation.

---

## Status Overview

| Gap | Feature | Original Status | **Current Status** | Docs |
|-----|---------|----------------|--------------------|----|
| 9 | OpenAI Responses API | ✅ Exists | ✅ Exists in praisonaiui | [API Ref](../api/features-api.md#openai-compatible-api) |
| 11 | Memory/Knowledge Search | 🟡 Partial | ✅ **Implemented** — `MemoryProtocol` + `SDKMemoryManager` | [API Ref](../api/features-api.md#memory) |
| 12 | Additional Channels | 🟡 Partial | ✅ **SDK bots exist** | [API Ref](../api/features-api.md#channels) |
| 13 | Plugin Marketplace UI | 🔴 Missing | ✅ **Implemented** — `MarketplaceProtocol` + `LocalMarketplaceManager` | [Marketplace](marketplace.md) |
| 16 | Code Execution View | 🟡 Partial | ✅ **Implemented** — `CodeExecutionProtocol` + `SandboxExecutionManager` | [Code Execution](code-execution.md) |
| 18 | i18n Framework | 🔴 Missing | ✅ **Implemented** — `I18nProtocol` + `JSONLocaleManager` (en/es/fr) | [i18n](i18n.md) |
| 20 | PWA / Mobile | 🔴 Missing | ✅ **Implemented** — `PWAProtocol` + `DefaultPWAManager` | [PWA](pwa.md) |
| 21 | TTS Integration | 🔴 Missing | ✅ **Implemented** — `TTSProtocol` + `BrowserTTSManager` / `OpenAITTSManager` | [TTS](tts.md) |
| 23 | Media Understanding | 🔴 Missing | ✅ **Implemented** — `MediaAnalysisProtocol` + `VisionAnalysisManager` | [Media Analysis](media-analysis.md) |
| 24 | Device Pairing | 🔴 Missing | ✅ **Implemented** — `PairingProtocol` + `DefaultPairingManager` | [Device Pairing](device-pairing.md) |

---

## Gap 9: OpenAI Responses API — ✅ NOT A GAP

Already exists in `praisonaiui/features/openai_api.py` (606 lines, 17 routes including `/v1/responses`). No SDK work needed.

---

## Gap 11: Memory/Knowledge Search — ✅ NOT A REAL GAP

### What Actually Exists in praisonai SDK

| Component | File | Lines | Status |
|-----------|------|-------|--------|
| `Memory` class | `praisonaiagents/memory/memory.py` | **1,874** | ✅ Complete |
| `FileMemory` | `praisonaiagents/memory/file_memory.py` | **1,619** | ✅ Zero-dependency |
| Short/Long-term memory | `store_short_term()`, `store_long_term()`, `search_*()` | — | ✅ |
| Entity memory | `store_entity()`, `get_entity()` | — | ✅ |
| ChromaDB vector search | `_init_chroma()`, embedding-based search | — | ✅ |
| MongoDB support | `_init_mongodb()`, Atlas Vector Search | — | ✅ |
| Mem0 integration | `_init_mem0()`, graph memory | — | ✅ |
| Agent integration | `Agent._init_memory()`, `get_memory_context()` | — | ✅ |
| Quality scoring | `compute_quality_score()`, `search_with_quality()` | — | ✅ |
| Auto-promote | `FileMemory.config["auto_promote"]` | — | ✅ |

> [!IMPORTANT]
> The "Chat → Memory bridge" already exists: `Agent.get_memory_context(query)` injects memory into prompts automatically. The "auto-save" already exists: `FileMemory.config["auto_promote"]` promotes important short-term to long-term.

### What's Left (UI-only)

- Memory sidebar component in `chat.js` to display relevant memories
- Wire praisonaiui's `memory.py` to use the SDK's `Memory` class instead of the in-memory dict

---

## Gap 12: Additional Channels — ✅ MOSTLY NOT A GAP

### What Actually Exists in praisonai SDK

| Bot | File | Lines | Status |
|-----|------|-------|--------|
| `DiscordBot` | `praisonai/bots/discord.py` | **487** | ✅ Complete |
| `TelegramBot` | `praisonai/bots/telegram.py` | **710** | ✅ Complete |
| `SlackBot` | `praisonai/bots/slack.py` | **593** | ✅ **Already implemented** |
| `WhatsAppBot` | `praisonai/bots/whatsapp.py` | **959** | ✅ **Already implemented** (Cloud API + Web mode) |

All four major bots include: full message handling, session management, STT/audio support, rate limiting, and resilience (reconnection, backoff).

### What's Left (Low Value)

| Channel | Difficulty | Value | Recommendation |
|---------|-----------|-------|----------------|
| Google Chat | Medium | Low (niche enterprise) | Defer |
| Signal | High (signal-cli) | Low | Defer |
| Nostr | Medium | Very Low | Defer |
| iMessage | High (macOS-only, AppleScript) | Low | Defer |

### What's Left (UI-only)

- Wire praisonaiui's `channels.py` to launch actual SDK bots instead of config-only management

---

## Gap 13: Plugin Marketplace UI — 🔴 UI-ONLY

The SDK already has `praisonaiagents/plugins/` with plugin manager, hook-based architecture, and tool registration. The missing piece is a **frontend marketplace page** in praisonaiui for browsing/installing plugins.

### TODO (praisonaiui only)

| Task | Where | Priority |
|------|-------|----------|
| Create marketplace frontend view | `views/marketplace.js` | Medium |
| Create plugin registry API | `features/marketplace.py` | Medium |

---

## Gap 16: Code Execution View — 🟡 UI-ONLY

The SDK has `execute_code` tool with sandboxed execution and security hooks. The gap is a **dedicated code editor page** in the dashboard.

### TODO (praisonaiui only)

| Task | Where | Priority |
|------|-------|----------|
| Create code editor frontend (Monaco/CodeMirror) | `views/code-editor.js` | Low |
| Create execution API | `features/code_execution.py` | Low |

---

## Gap 18: i18n Framework — 🔴 UI-ONLY

No SDK work needed. Frontend-only: extract strings, create locale files, add language switcher.

---

## Gap 20: PWA / Mobile — 🔴 UI-ONLY

No SDK work needed. Frontend-only: `manifest.json`, service worker, responsive CSS.

---

## Gap 21: TTS Integration — 🟡 MINOR SDK GAP

### What Exists in praisonai SDK

| Component | Where | Status |
|-----------|-------|--------|
| TTS in Telegram bot | `_send_response_with_media()`, `send_voice()` | ✅ |
| TTS in Slack bot | `_send_response_with_media()`, `files_upload_v2()` | ✅ |
| STT tool | `praisonai/tools/audio.py` → `stt_tool` | ✅ |
| Media parsing | `split_media_from_output()`, `is_audio_file()` | ✅ |

### What's Missing (Minor)

A standalone `tts_tool` that wraps OpenAI's TTS API:

```python
@tool
def tts_tool(text: str, voice: str = "alloy", model: str = "tts-1") -> str:
    """Convert text to speech audio file."""
    # Returns path to generated audio file
```

### TODO

| Task | Where | Priority |
|------|-------|----------|
| Add `tts_tool` wrapping OpenAI TTS API | `praisonai/tools/audio.py` | Low |
| Add 🔊 button to chat messages | `views/chat.js` (UI-only) | Low |

---

## Gap 23: Media Understanding — ✅ NOT A GAP

### What Actually Exists in praisonai SDK

| Component | File | Lines | Status |
|-----------|------|-------|--------|
| `VisionAgent` | `praisonaiagents/agent/vision_agent.py` | **449** | ✅ Complete |
| `OCRAgent` | `praisonaiagents/agent/ocr_agent.py` | **298** | ✅ Complete |

**VisionAgent capabilities:** `describe()`, `analyze()`, `compare()` (multi-image), `extract_text()`. Supports GPT-4o, Claude 3.5, Gemini 1.5.

**OCRAgent capabilities:** PDF and image OCR, Mistral OCR model, page-by-page extraction.

### What's Left (UI-only)

- Wire image attachments in chat to VisionAgent for inline analysis
- Add image preview/analysis UI in chat messages

---

## Gap 24: Device Pairing — 🔴 UI-ONLY

Not an SDK concern. QR codes, session sync, and device management are UI/infrastructure features.

---

## Corrected Priority Matrix

Since nearly all SDK gaps are resolved, the remaining work is **praisonaiui frontend only**:

| Priority | Feature | Type | Effort |
|----------|---------|------|--------|
| P1 | Wire `memory.py` to SDK's `Memory` class | UI integration | Low |
| P1 | Wire `channels.py` to launch SDK bots | UI integration | Medium |
| P1 | Wire chat attachments to `VisionAgent` | UI integration | Low |
| P2 | Plugin marketplace frontend | UI feature | High |
| P2 | Code execution editor page | UI feature | Medium |
| P3 | `tts_tool` addition | SDK (minor) | Low |
| P3 | PWA manifest + service worker | UI feature | Medium |
| P3 | i18n framework | UI feature | Medium |
| P3 | Device pairing | UI feature | High |

> [!NOTE]
> The **only SDK work** remaining is adding a `tts_tool` (low priority). Everything else is praisonaiui frontend integration work — wiring existing SDK capabilities into the dashboard UI.

# Gateway Chat

Source: https://ui.praison.ai/docs/features/gateway-chat

# Gateway Chat

Real-time AI agent chat with **WebSocket streaming**, markdown rendering, tool call display, and session management.

![Chat Interface](../images/chat-interface.png)

## Quick Start

```python
import praisonaiui as aiui
from praisonaiui.server import create_app

aiui.set_style("dashboard")
app = create_app()

# Chat is auto-registered — just start the server
# Navigate to the dashboard and open the Chat page
```

```bash
aiui run app.py
# → Dashboard with Chat page, WebSocket streaming, and session management
```

## How It Works

### Full Streaming Data Flow

A chat message travels through 5 layers before reaching the browser:

    participant SDK as Agent.chat()<br/>(praisonaiagents)

    U->>JS: User types message, hits Send
    JS->>WS: {type: "chat", content: "Hello"}

## Agent Tool Resolution

Agents created via YAML config, CRUD API, jobs, or channel bots automatically get tools resolved through the `ToolResolver`. Tool names in config are resolved to callable Python functions from 4 sources:

1. Local `tools.py` file (backward compatibility)
2. `praisonaiagents.tools.TOOL_MAPPINGS` (built-in tools)
3. `praisonai_tools` package (community tools)
4. Tool registry (programmatically registered tools)

### YAML Configuration

```yaml
# ~/.praisonaiui/config.yaml (unified runtime config)
agents:
  researcher:
    instructions: "Research topics thoroughly."
    model: gpt-4o-mini
    tools:
      - internet_search        # Resolved to callable function
      - wikipedia_search
    reflection: true            # Enable self-reflection (default: true)
    role: "Senior Researcher"   # Optional CrewAI-style params
    goal: "Find accurate info"
    backstory: "Expert researcher"
```

### CRUD API

Agents created via `POST /api/agents` also support tools:

```json
{
  "name": "researcher",
  "instructions": "Research topics thoroughly.",
  "model": "gpt-4o-mini",
  "tools": ["internet_search"],
  "reflection": true
}
```

### Where Tool Resolution Applies

| Component | Tool Resolution |
|-----------|----------------|
| Gateway `_create_agents_from_config()` | ✅ `ToolResolver` |
| Integration `create_gateway_from_yaml()` | ✅ `ToolResolver` |
| Provider `_get_or_create_agent()` | ✅ Default tools |
| Channel bot `_start_channel_bot()` | ✅ Default tools |
| Jobs `_execute_job()` fallback | ✅ `ToolResolver` |
| CRUD agents `_run()` fallback | ✅ `ToolResolver` |
| CRUD agents `_sync_to_gateway()` | ✅ `ToolResolver` |

## Features

### Markdown Rendering

Assistant messages are rendered with full markdown support:

- **Bold**, *italic*, ~~strikethrough~~
- Inline `code` and fenced code blocks with syntax highlighting
- Ordered and unordered lists
- Links (auto-detected and rendered safely)

### Tool Call Display

![Tool Call Streaming](../images/tool-streaming.png)

When agents use tools, each call is displayed as a collapsible card:

- Tool name and status indicator (running/completed/failed)
- Input arguments (JSON)
- Output results (rendered in code blocks)

#### Tool Call Lifecycle

Tool calls go through 4 stages: **emit → enrich → dedup → persist**.

**1. Emit** — The SDK fires `TOOL_CALL_START` / `DELTA_TOOL_CALL` / `TOOL_CALL_END` events via `StreamEventEmitter`. The provider maps these to `RunEvent` types (`TOOL_CALL_STARTED`, `TOOL_CALL_COMPLETED`).

**2. Enrich** — `_run_and_broadcast()` in `chat.py` enriches each tool call event with display-friendly fields via `_enrich_tool_payload()`:

| Field | Source | Example |
|-------|--------|---------|
| `icon` | Mapped from tool name | 🔍, 📝, 💾 |
| `description` | Generated from name + args | "🔍 Searching for 'Django latest version'" |
| `step_number` | Auto-incrementing counter per run | 1, 2, 3 |
| `formatted_result` | Truncated result string | "✓ Done" |
| `tool_call_id` | SDK-assigned or UUID fallback | "call_abc123" |

**3. Dedup** — Both `DELTA_TOOL_CALL` (stream) and hook callbacks fire for the same tool call. The handler uses `_seen_tool_started` / `_seen_tool_completed` sets keyed by `tool_call_id` and `name` to suppress duplicates. A re-broadcast with `has_complete_args=True` is allowed to update the description with keyword-rich text.

**4. Persist** — After the run completes, all enriched tool calls are merged by `tool_call_id` into `collected_tool_calls` and saved alongside the assistant message:

```python
msg_data = {
    "role": "assistant",
    "content": full_response,
}
if collected_tool_calls:
    msg_data["toolCalls"] = list(collected_tool_calls.values())
await _datastore.add_message(session_id, msg_data)
```

#### Tool Call Persistence Schema

Tool calls are persisted alongside assistant messages in the datastore. When a session is reloaded from history, tool call steps are reconstructed from the `toolCalls` array on each assistant message.

Assistant message schema in the datastore:

```json
{
  "role": "assistant",
  "content": "Final response text",
  "toolCalls": [
    {
      "name": "search_web",
      "description": "🔍 Searching for 'Django latest version'",
      "icon": "🔍",
      "step_number": 1,
      "args": {"query": "Django latest version"},
      "result": "...",
      "formatted_result": "✓ Done",
      "status": "done",
      "tool_call_id": "tc_abc123",
      "type": "tool_call_completed"
    }
  ]
}
```

#### History Reload Rendering

```mermaid
sequenceDiagram
    participant Browser as chat.js
    participant API as GET /api/chat/history/{id}
    participant DS as DataStore

    Browser->>API: fetch('/api/chat/history/' + sessionId)
    API->>DS: get_messages(session_id)
    DS-->>API: messages (with toolCalls on assistant msgs)
    API-->>Browser: {messages: [...]}
    
    loop forEach message
        alt role == assistant
            Browser->>Browser: appendMessage('assistant', content)
            loop forEach toolCalls[]
                Browser->>Browser: appendToolCall(tc)
                Browser->>Browser: updateToolCall(tc, result)
            end
        else role == user
            Browser->>Browser: appendMessage('user', content)
        end
    end
```

### Session Management

- **New Session**: Click "New Chat" to create a fresh session
- **Session History**: Switch between sessions in the sidebar
- **Message History**: Full conversation history per session via REST API

### Message Abort

- Click the **Stop** button (or send `chat_abort` via WebSocket) to cancel an in-progress agent run
- The partial response is preserved in history

### File Attachments

Upload files to include with your chat messages — see [Attachments](attachments.md) for details.

## Session Persistence

Chat history is persisted via the `BaseDataStore` interface (`datastore.py`). Two implementations are available:

| DataStore | Persistence | Default |
|-----------|-------------|--------|
| `MemoryDataStore` | Volatile (in-memory only) | Yes (fallback) |
| `JSONFileDataStore` | Disk (`~/.praisonaiui/sessions/`) | Yes (when `data_dir` configured) |

Each session is a JSON file containing:

```json
{
  "id": "session-uuid",
  "title": "Auto-generated from first user message",
  "created_at": "2026-03-17T08:00:00Z",
  "updated_at": "2026-03-17T08:01:00Z",
  "messages": [
    {"role": "user", "content": "..."},
    {"role": "assistant", "content": "...", "toolCalls": [...]}
  ]
}
```

Messages are appended via `add_message()` and retrieved via `get_messages()`. Both methods are `async` to support future database backends.

### Response Content Strategy

The `content` field on assistant messages stores the SDK's final response from `agent.chat()` — the same text displayed by `finalizeDelta()` in the live view. This ensures the reloaded view matches what the user saw during streaming.

> [!IMPORTANT]
> During streaming, text tokens are accumulated in `full_response`. However, when `RUN_COMPLETED` arrives with `event.content` (the SDK's authoritative return value), it **replaces** the accumulated tokens for storage. This prevents intermediate narrative text from being duplicated on reload.

## Chat Message Model

```python
@dataclass
class ChatMessage:
    role: str              # "user" | "assistant" | "system"
    content: str           # Message text
    session_id: str        # Session identifier
    message_id: str        # Auto-generated UUID
    agent_name: str        # Optional agent name
    timestamp: float       # Unix timestamp
    metadata: Dict         # Optional metadata (tool calls, etc.)
```

## WebSocket Protocol

### Client → Server

```json
// Send a message
{"type": "chat", "content": "Hello!", "session_id": "abc-123"}

// Abort a run
{"type": "chat_abort", "session_id": "abc-123"}

// Keepalive ping
{"type": "ping"}
```

### Server → Client

All events include `session_id` and `run_id`.

```json
// Streaming text token
{"type": "run_content", "token": "Hello", "session_id": "...", "run_id": "..."}

// Tool call started (enriched)
{
  "type": "tool_call_started",
  "name": "search_web",
  "tool_call_id": "call_abc123",
  "args": {"query": "Django"},
  "description": "🔍 Searching for 'Django'",
  "icon": "🔍",
  "step_number": 1
}

// Tool call completed (enriched)
{
  "type": "tool_call_completed",
  "tool_call_id": "call_abc123",
  "name": "search_web",
  "result": "Django 5.1 released...",
  "formatted_result": "✓ Done",
  "status": "done"
}

// Intermediate LLM narrative text (between tool calls)
{"type": "llm_content", "content": "Let me search for that..."}

// Reasoning step (thinking)
{"type": "reasoning_step", "step": "Analyzing the query..."}

// Agent asks for user input
{"type": "run_paused", "question": "Which version?", "options": ["5.0", "5.1"]}

// Memory updates
{"type": "memory_update_started"}
{"type": "updating_memory"}
{"type": "memory_update_completed"}

// Run completed (content = SDK's final response)
{"type": "run_completed", "content": "Here are the results..."}

// Error / Cancel
{"type": "run_error", "error": "..."}
{"type": "run_cancelled"}

// Team variants (multi-agent)
{"type": "team_run_started", "agent_name": "researcher"}
{"type": "team_run_content", "token": "..."}
{"type": "team_tool_call_started", ...}
{"type": "team_tool_call_completed", ...}
{"type": "team_run_completed", "content": "..."}

// Channel bot messages
{"type": "channel_message", "platform": "slack", "sender": "User", "content": "..."}
{"type": "channel_response", "platform": "slack", "content": "..."}

// Keepalive
{"type": "pong"}
```

## REST API

| Endpoint | Method | Description |
|----------|--------|-------------|
| `/api/chat/send` | POST | Send a message (non-streaming) |
| `/api/chat/history/{session_id}` | GET | Get message history for a session |
| `/api/chat/abort` | POST | Abort an active run |
| `/api/chat/ws` | WebSocket | Real-time chat streaming |

### Send Message

```bash
curl -X POST http://localhost:8083/api/chat/send \
  -H "Content-Type: application/json" \
  -d '{"content": "Hello!", "session_id": "my-session"}'
```

### Get History

```bash
curl http://localhost:8083/api/chat/history/my-session
```

Response includes `toolCalls` on assistant messages:

```json
{
  "messages": [
    {"role": "user", "content": "Search for Django"},
    {
      "role": "assistant",
      "content": "Here are the results...",
      "toolCalls": [
        {
          "name": "search_web",
          "description": "🔍 Searching for 'Django'",
          "step_number": 1,
          "status": "done",
          "result": "..."
        }
      ]
    }
  ]
}

## Frontend (chat.js)

The chat frontend is a vanilla JavaScript plugin that auto-loads as a dashboard page. Two versions exist:

| Version | Path | Notes |
|---------|------|-------|
| Plugin | `aiui/plugins/views/chat.js` | Used in development |
| Template | `src/praisonaiui/templates/frontend/plugins/views/chat.js` | Bundled with package, has enriched UI |

### Core Functions

| Function | Purpose |
|----------|--------|
| `connectWebSocket()` | Establish WS with auto-reconnect (3s delay) |
| `handleWsMessage(data)` | Event dispatch — routes to rendering functions |
| `appendMessage(role, content, agentName)` | Render a complete message (history load) |
| `appendDelta(token, agentName)` | Streaming — append token to `currentDeltaEl` |
| `finalizeDelta(content, agentName)` | End streaming — replace with final content |
| `appendToolCall(name/data, args/status)` | Render tool call card |
| `updateToolCall(name/data, result, status)` | Update card with result |
| `appendReasoning(step)` | Render thinking step |
| `appendAskWidget(question, options)` | Render user-input prompt |
| `appendMemoryIndicator(text)` | Show memory update spinner |
| `loadSession(sessionId)` | Fetch history → render messages + tool calls |
| `restoreSessionHistory(sessionId)` | Same as above, on WS reconnect |
| `renderMarkdown(text)` | Custom zero-dependency markdown renderer |
| `escapeHtml(str)` | XSS prevention sanitizer |

### Streaming Text Model

During streaming, **all text tokens go into a single `currentDeltaEl` DOM element** — even across tool call boundaries. Tool call cards are sibling elements inserted alongside the text element. When `run_completed` arrives, `finalizeDelta(content)` **replaces** the accumulated text with the SDK's final response.

## Theming

The chat UI supports dark and light themes via CSS custom properties — see [Theme System](theme-system.md).

---

## 1. Add a new page

**Goal**: Show a new page in the sidebar with custom content.

```python
import praisonaiui as aiui

@aiui.page("analytics", title="Analytics", icon="📈", group="Custom")
async def analytics():
    return aiui.layout([
        aiui.columns([
            aiui.card("Revenue", value="$12,340"),
            aiui.card("Users", value="1,204"),
        ]),
        aiui.chart(data=[10, 20, 30], type="line"),
    ])
```

**What happens**:

1. The page is registered in the server's page registry.
2. It appears in the sidebar at `/api/pages`.
3. When the user clicks it, the frontend fetches `/api/pages/analytics/data`.
4. Your handler returns a dict; `aiui.layout()` wraps it in `{"_components": [...]}`.
5. `dashboard.js` loops over `_components` and calls `renderComponent(comp)` on each.

See [Dashboard](dashboard.md) for the full `@aiui.page()` signature.

---

## 2. Add an interactive form

**Goal**: Let users submit data from the UI back to your Python code.

```python
import praisonaiui as aiui

_saved = []

@aiui.page("contact", title="Contact", icon="📝")
async def contact_form():
    return aiui.layout([
        aiui.form_action(
            "contact",
            submit_label="Save",
            children=[
                aiui.text_input("Name"),
                aiui.text_input("Email"),
                aiui.select_input("Role", options=["Engineer", "PM"]),
                aiui.checkbox_input("Subscribe", checked=True),
            ],
        ),
    ])

@aiui.register_page_action("contact")
async def handle_contact(data: dict) -> dict:
    _saved.append(data)
    return {"status": "saved", "count": len(_saved)}
```

**What happens**:

1. The form renders with all inputs.
2. On submit, the frontend POSTs to `/api/pages/contact/action`.
3. The server invokes `handle_contact(data)` with the form values keyed by label.
4. The returned dict is sent back to the browser as JSON.

> **Note**: Input labels become dict keys. Use distinct labels per input.

---

## 3. Add a custom component type

**Goal**: Add a new UI widget that doesn't exist in the 48 built-ins.

### Step 1 — Python side: return a dict with your new type

```python
@aiui.page("activity", title="Activity", icon="🕒")
async def activity():
    return aiui.layout([
        {
            "type": "timeline",   # ← custom type
            "events": [
                {"time": "09:00", "label": "Deploy", "icon": "🚀"},
                {"time": "13:00", "label": "Review", "icon": "🔍"},
            ],
        },
    ])
```

**If you stop here**, the component renders as formatted JSON (graceful fallback).

### Step 2 — Client side: register a renderer

Put this in a `plugin.js` file (or paste into DevTools Console):

```javascript
window.aiui.registerComponent('timeline', function(comp) {
    const el = document.createElement('div');
    el.className = 'db-timeline';
    (comp.events || []).forEach(ev => {
        const row = document.createElement('div');
        row.innerHTML = `<b>${ev.icon}</b> ${ev.time} — ${ev.label}`;
        el.appendChild(row);
    });
    return el;
});
```

**What happens**:

1. `renderComponent(comp)` checks `COMPONENT_REGISTRY[comp.type]` before the built-in switch.
2. Your renderer takes priority and returns a DOM element.

### Auto-load `plugin.js` from Python

Use `aiui.set_custom_js(path)` to ship client-side extensions directly from
your app:

```python
import praisonaiui as aiui

aiui.set_custom_js("plugin.js")   # reads file, serves at /custom.js,
                                   # injects <script> after the plugin loader
```

The script runs **after** the plugin loader, so `window.aiui.registerView`
and `window.aiui.registerComponent` are ready when it executes. No DevTools
workaround needed.

---

## 4. Add a client-only page

**Goal**: A page rendered entirely in the browser — no server round-trip on navigation.

```javascript
// In plugin.js
window.aiui.registerView('live-feed', async (container) => {
    container.innerHTML = '<h1>Live Feed</h1>';
    const ws = new WebSocket('wss://your-feed.example.com');
    ws.onmessage = (e) => {
        const div = document.createElement('div');
        div.textContent = e.data;
        container.appendChild(div);
    };
    // Store ws for cleanup
    container._ws = ws;
}, () => {
    // Cleanup when user navigates away
    if (container._ws) container._ws.close();
});
```

Still register a placeholder page in Python so it appears in the sidebar:

```python
@aiui.page("live-feed", title="Live Feed", icon="📡")
async def live_feed():
    return aiui.layout([aiui.text("Loading…")])
```

**What happens**:

1. `registerView` takes priority over the built-in + server-side rendering.
2. Navigation calls your `render(container)` function.
3. When the user navigates away, your `cleanup()` function runs.

---

## 5. Register a custom theme

```python
aiui.register_theme("ocean", {"accent": "#0077b6"})
aiui.set_theme(preset="ocean")
```

See [CSS Architecture](css-architecture.md) for all variables.

---

## 6. Add a new AI provider

```python
from praisonaiui.provider import BaseProvider, RunEvent, RunEventType

class MyProvider(BaseProvider):
    async def run(self, message, **kw):
        yield RunEvent(type=RunEventType.RUN_STARTED)
        yield RunEvent(type=RunEventType.RUN_CONTENT, token="Hello")
        yield RunEvent(type=RunEventType.RUN_COMPLETED, content="Hello")

aiui.set_provider(MyProvider())
```

See [Providers](../concepts/providers.md).

---

## 7. Add a feature module (advanced)

Features live in `praisonaiui/features/*.py` and implement `BaseFeatureProtocol`:

```python
from praisonaiui.features import BaseFeatureProtocol, register_feature
from starlette.routing import Route
from starlette.responses import JSONResponse

class MyFeature(BaseFeatureProtocol):
    name = "my-feature"
    feature_name = "my-feature"

    def routes(self):
        return [
            Route("/api/my-feature", self._handler, methods=["GET"]),
        ]

    async def _handler(self, request):
        return JSONResponse({"data": "hello"})

register_feature(MyFeature())
```

See [Protocol Architecture](protocol-architecture.md).

## Is This the Best Approach?

### Strengths ✅

- **Clean separation** — Python returns dicts, client renders DOM. You can mix and match server/client work per-feature.
- **Graceful degradation** — Unknown component types render as JSON (no crashes).
- **Zero build step for Python users** — No webpack/TS compile required for server-side pages.
- **Single source of truth** — Every feature has a protocol ABC.
- **Hot-swap friendly** — `window.aiui.registerView/Component` updates live without server restart.

### Previously reported gaps — all closed ✅

| Gap | Resolution |
|-----|------------|
| No `aiui.set_custom_js(path)` | **Implemented** — serves the file at `/custom.js` and injects a `<script>` tag after the plugin loader. Unit tests: `tests/unit/test_custom_js.py` (10 tests). |
| `form_action` uses input labels as keys | **Implemented** — every form input now accepts an optional `name=` kwarg that becomes the submit-key. Tests: `tests/unit/test_form_input_names.py` (18 tests). |
| No typed Python ⇄ JS contract | **Implemented** — `aiui.register_component_schema(type, schema)` + `GET /api/components/schemas`. Built-in schemas are auto-derived from `ui.py` signatures. Tests: `tests/unit/test_component_schemas.py` (9 tests). |
| `/api/features` cold-start slow | **Mitigated** — `info()` calls are parallelized via `asyncio.gather`. Warm calls are now instant; cold starts are dominated by LiteLLM import (out of scope). |
| `pygments 2.20` mkdocs build crash on `providers.md` | **Fixed** — `docs_hooks.py` patches `pymdownx.BlockHtmlFormatter.__init__` to coerce `filename=None` → `""`. |

### When NOT to use this approach

- **You need a full SPA with routing**: Use the Next.js adapter or scaffold a React project with `aiui init --frontend`.
- **Your UI needs TypeScript types**: Use the TypeScript SDK (`@praisonaiui/runtime`).
- **You need server-sent events beyond chat**: Extend `BaseFeatureProtocol` with a WebSocket route.

---

## Checklist for a New Feature

- [ ] Decide: is it a page, a component, or a backend module?
- [ ] Write the Python side first (returns a dict / routes).
- [ ] If you added a new component type: implement the JS renderer.
- [ ] Write a unit test (see `tests/unit/test_form_action.py` as an example).
- [ ] Add a runnable example under `examples/python/`.
- [ ] Update the docs under `docs/features/` or `docs/api/`.
- [ ] Run `mkdocs build --strict`.
- [ ] Run `pytest tests/unit -v`.

# Internationalization (i18n)

Source: https://ui.praison.ai/docs/features/i18n

# Internationalization (i18n)

Multi-language support with **locale switching**, string lookup, and variable interpolation. Ships with English, Spanish, and French.

## Quick Start

```bash
# List available locales
curl http://localhost:8083/api/i18n/locales

# Get strings for a locale
curl http://localhost:8083/api/i18n/strings/es

# Translate a key
curl -X POST http://localhost:8083/api/i18n/translate \
  -H "Content-Type: application/json" \
  -d '{"key":"app.welcome","locale":"fr"}'
```

## How It Works

```mermaid
graph LR
    A["Frontend"] -->|"t('app.welcome', 'es')"| B{"I18nProtocol"}
    B --> C["JSONLocaleManager"]
    C --> D["en: Welcome to PraisonAI"]
    C --> E["es: Bienvenido a PraisonAI"]
    C --> F["fr: Bienvenue sur PraisonAI"]
```

The i18n system uses a **key-based** translation approach:

1. Each string has a dotted key (e.g., `app.welcome`, `chat.send`)
2. Keys are organized by namespace: `app`, `chat`, `nav`, `error`
3. Variable interpolation: `{name}` placeholders are replaced at lookup time
4. Unknown keys return the key itself as fallback

## Built-in Locales

| Locale | Language | Strings |
|--------|----------|---------|
| `en` | English | 11 |
| `es` | Spanish (Español) | 11 |
| `fr` | French (Français) | 11 |

## Configuration

```python
from praisonaiui.features.i18n import JSONLocaleManager, set_i18n_manager

mgr = JSONLocaleManager(default_locale="es")
set_i18n_manager(mgr)

# Translate
mgr.t("app.welcome")          # "Bienvenido a PraisonAI"
mgr.t("app.welcome", "fr")    # "Bienvenue sur PraisonAI"
```

## REST API

| Endpoint | Method | Description |
|----------|--------|-------------|
| `/api/i18n/locales` | GET | List available locales |
| `/api/i18n/strings/{locale}` | GET | Get all strings for a locale |
| `/api/i18n/translate` | POST | Translate a key with optional variables |
| `/api/i18n/locale` | GET | Get current default locale |
| `/api/i18n/locale` | POST | Set default locale |

### GET /api/i18n/strings/es

```json
{
    "locale": "es",
    "strings": {
        "app.title": "PraisonAI",
        "app.welcome": "Bienvenido a PraisonAI",
        "chat.placeholder": "Escribe tu mensaje...",
        "chat.send": "Enviar",
        "chat.thinking": "Pensando...",
        "nav.dashboard": "Panel",
        "nav.agents": "Agentes",
        "nav.settings": "Configuración",
        "nav.sessions": "Sesiones",
        "error.generic": "Algo salió mal",
        "error.network": "Error de red"
    },
    "count": 11
}
```

### POST /api/i18n/translate

```json
// Request
{"key": "app.welcome", "locale": "fr"}

// Response
{"key": "app.welcome", "text": "Bienvenue sur PraisonAI"}
```

# Image Preview in Chat

Source: https://ui.praison.ai/docs/features/image-preview-chat

# Image Preview in Chat

Protocol-driven inline media for agent-generated images (and other element types) during chat streaming. Any backend that implements `BaseProvider` can emit images without PraisonAI-specific code in chat or the frontend.

## Problem This Solves

Before this feature, PraisonAIUI could **render** images (`Message.add_image`, `ElementRenderer`) but the **wire protocol dropped media** during agent runs. ImageAgent / tool results appeared as JSON in the tool-call panel instead of inline `<img>` previews.

## Architecture

Modular layers — same pattern as [A2UI surfaces](./agent-ui-host.md):

```mermaid
sequenceDiagram
    participant Backend as Provider_or_Tool
    participant Detect as media_utils.py
    participant Protocol as RunEvent_MESSAGE_ELEMENT
    participant Chat as chat.py
    participant UI as chat.js_React

    Backend->>Detect: tool result or callback payload
    Detect->>Protocol: normalised element dict
    Protocol->>Chat: broadcast message_element
    Chat->>UI: WebSocket / SSE frame
    UI->>UI: appendMediaElement / ElementRenderer
    Chat->>Chat: persist elements in session history
```

### Layer responsibilities

| Layer | Module | Backend-agnostic? |
|-------|--------|-------------------|
| **Detection** | [`media_utils.py`](../../src/praisonaiui/media_utils.py) | Yes — normalises OpenAI, URL, b64, element dicts |
| **Protocol** | [`provider.py`](../../src/praisonaiui/provider.py) — `RunEventType.MESSAGE_ELEMENT` | Yes |
| **Adapter** | [`providers/__init__.py`](../../src/praisonaiui/providers/__init__.py) — PraisonAI bridge only | No — maps SDK/callback queue → protocol |
| **Transport** | [`chat.py`](../../src/praisonaiui/features/chat.py) — broadcast + persist | Yes |
| **Storage** | [`attachments.py`](../../src/praisonaiui/features/attachments.py) — `GET /api/chat/media/{id}` | Yes — reuses attachment store for b64 |
| **UI** | [`chat.js`](../../src/praisonaiui/templates/frontend/plugins/views/chat.js), [`ElementRenderer`](../../src/frontend/src/chat/MultimediaElements.tsx) | Yes — renders `{type, url, alt}` |

Detection and UI do **not** import PraisonAI. Only the provider adapter knows ImageAgent / OpenAI `{data: [{url}]}` shapes.

## Wire protocol

### Event type

```
type: "message_element"
element: { "type": "image", "url": "...", "alt": "..." }
session_id: "..."
run_id: "..."
```

Defined in Python as `RunEventType.MESSAGE_ELEMENT` and mirrored in [`types.ts`](../../src/frontend/src/types.ts).

### Helper (any provider)

```python
from praisonaiui.provider import BaseProvider, RunEvent, RunEventType

yield BaseProvider.message_element_event({
    "type": "image",
    "url": "https://example.com/out.png",
    "alt": "Generated image",
})
```

Element shape reuses the existing [message element schema](./message-elements.md) (`image`, `pdf`, `video`, `audio`, `file`, `code`).

## Data flow paths

### 1. Custom provider (swappable backend)

```python
import praisonaiui as aiui
from praisonaiui.provider import BaseProvider, RunEvent, RunEventType

class MyImageProvider(BaseProvider):
    async def run(self, message, *, session_id=None, agent_name=None, **kw):
        yield RunEvent(type=RunEventType.RUN_STARTED)
        # Call any image API here (OpenAI, Stability, local, etc.)
        yield BaseProvider.message_element_event({
            "type": "image",
            "url": image_url,
            "alt": "Generated image",
        })
        yield RunEvent(type=RunEventType.RUN_COMPLETED, content="Here is your image.")

aiui.set_provider(MyImageProvider())
```

Example app: [`examples/python/30-image-preview/app.py`](../../examples/python/30-image-preview/app.py).

### 2. Callback handler (`@aiui.reply`)

```python
import praisonaiui as aiui
from praisonaiui import Message

@aiui.reply
async def on_message(msg):
    m = Message(content="Here is your image:")
    m.add_image("https://example.com/chart.png", alt="Chart")
    await m.send()
```

`PraisonAIProvider` maps queue events (`image`, `message` + `elements`) → `MESSAGE_ELEMENT`.

### 3. Tool results (automatic detection)

When a tool completes, `tool_completed_extra()` in [`a2ui_utils.py`](../../src/praisonaiui/a2ui_utils.py) calls `build_media_extra()` from `media_utils`. Supported shapes:

| Input shape | Example |
|-------------|---------|
| OpenAI / ImageAgent | `{"data": [{"url": "...", "b64_json": "...", "revised_prompt": "..."}]}` |
| Explicit element | `{"type": "image", "url": "..."}` |
| Plain URL string | `"https://cdn.example.com/out.png"` |
| Data URL | `"data:image/png;base64,..."` |
| Nested elements | `{"elements": [{"type": "video", "url": "..."}]}` |

`chat.py` broadcasts `message_element` for each detected element and attaches `elements` to the persisted assistant message.

### 4. ImageAgent direct mode

If the registered agent's `chat()` returns an OpenAI-shaped dict, `PraisonAIProvider._run_direct_mode` runs `extract_media_elements()` and emits `MESSAGE_ELEMENT` events before `RUN_COMPLETED`.

## Base64 storage

Large `b64_json` payloads are **not** stored inline in message history. They are decoded and saved via `AttachmentManager`, then served at:

```
GET /api/chat/media/{attachment_id}
```

If storage fails, the system falls back to a `data:image/png;base64,...` URL.

## Frontend rendering

| Surface | Handler |
|---------|---------|
| Dashboard chat (template) | `chat.js` — `case 'message_element': appendMediaElement()` |
| React chat | `streamingStore.ts` — `pendingElements` + `ElementRenderer` |
| Tool call panel | Thumbnail from `toolCall.elements` when expanded |
| Session reload | `elements` on messages from `/api/chat/history` and `/sessions/{id}/runs` |

See also [Message Elements](./message-elements.md) for element properties and display modes.

## Deduplication

`_collect_element()` in `chat.py` dedupes by URL so the same image is not stored twice when both a `MESSAGE_ELEMENT` event and a tool completion carry the same URL.

## Out of scope

- **REST image generation** (`POST /v1/images/generations`) — separate OpenAI-compat endpoint; not wired into chat streaming
- **Canvas / A2UI surfaces** — separate feature for agent-driven UI catalogs
- **Auto-registering ImageAgent** — agents are configured explicitly by the user

## Tests

```bash
pytest tests/unit/test_media_utils.py \
       tests/integration/test_chat_image_preview.py -v -o addopts=
```

Coverage includes: detection normalisation, b64 fallback, provider callback bridge, `_run_and_broadcast` persistence, media serve route, ImageAgent dict responses, URL dedup.

# AIUI Integration — Critical Review & Architecture Analysis

> **Principle**: AIUI's `config.yaml` is a **schemaless** YAML dict (`YAMLConfigStore`). The adapter must produce what AIUI already reads — AIUI's config structure is NOT modified. Additional keys are silently ignored.

| # | Criterion | Status |
|---|-----------|--------|
| AC-1 | 3rd runtime = adapter file + enum + registry | ✅ Done |
| AC-2 | Zero `name ===` outside adapters | ⚠️ 4 deferred (OpenClaw-specific) |

---

## 2. Current State — What's Done

### Hostaibot Protocol Refactoring ✅ Complete

11 files changed (+150 / -18). Verified with 1200/1240 tests passing.

| File | Change | Status |
|------|--------|--------|
| [types.ts](file:///Users/praison/hostaibot/src/lib/runtime/types.ts) | +3 methods: `parseConfig`, `serializeConfig`, `containerUser` | ✅ |
| [openclaw-adapter.ts](file:///Users/praison/hostaibot/src/lib/runtime/openclaw-adapter.ts) | JSON.parse/stringify, `"node"` | ✅ |
| [aiui-adapter.ts](file:///Users/praison/hostaibot/src/lib/runtime/aiui-adapter.ts) | Lazy `js-yaml` load/dump, `"root"` | ✅ |
| [channel-sync.ts](file:///Users/praison/hostaibot/src/lib/channel-sync.ts) | 4 leaks fixed (config path, parse, serialize, chown) | ✅ |
| [health/route.ts](file:///Users/praison/hostaibot/src/app/api/instances/%5Bid%5D/health/route.ts) | `JSON.parse` → `parseConfig()` | ✅ |
| [provision-queue.ts](file:///Users/praison/hostaibot/src/lib/provision-queue.ts) | `JSON.stringify` → `serializeConfig()` | ✅ |
| [openclaw/route.ts](file:///Users/praison/hostaibot/src/app/api/instances/%5Bid%5D/openclaw/route.ts) | Runtime guard (400 RUNTIME_MISMATCH) | ✅ |
| [api-error.ts](file:///Users/praison/hostaibot/src/lib/api-error.ts) | New RUNTIME_MISMATCH code | ✅ |
| [dashboard/page.tsx](file:///Users/praison/hostaibot/src/app/dashboard/page.tsx) | Wired `runtimeType` to tabs | ✅ |
| [config-builder.test.ts](file:///Users/praison/hostaibot/src/lib/__tests__/config-builder.test.ts) | +12 new tests | ✅ |

### Key Regression Fix

> [!IMPORTANT]
> `syncChannelConfig()` was NOT wired directly because consumer code passes **pre-decrypted** tokens (via `decryptSafe()`), while the adapter would receive raw encrypted DB values. The original `config.channels = channelsConfig` pattern was preserved — only format methods (`parseConfig`/`serializeConfig`/`containerUser`) are adapter-driven.

### 4 Deferred Leaks (OpenClaw-Specific)

| Leak | Why Deferred |
|------|-------------|
| `provision-queue` chown L289 | OpenClaw post-health — skipped for non-OpenClaw |
| `provision-queue` device pairing L358 | OpenClaw-specific feature |
| `health/route` model path L184 | Different config structures per runtime |
| `health/route` env check L202 | Different env vars per runtime |

These are not protocol operations — they're OpenClaw-specific features that correctly skip for other runtimes.

---

## 3. Protocol-Driven Assessment

### What AIUI's Config.yaml Already Reads (Unchanged)

```yaml
# AIUI config.yaml — schemaless, no modifications needed:
schema_version: 2
provider:
  model: "gpt-4o-mini"       # provider reads this
server:
  host: "0.0.0.0"
  port: 8003                  # Dockerfile EXPOSE 8082
channels:
  telegram_abc:               # arbitrary ID
    platform: telegram        # required for _start_channel_bot()
    config:
      bot_token: "..."        # also accepts "token" (channels.py L694)
    enabled: true
    auto_start: true
```

**Not in config**: API key (`OPENAI_API_KEY` env var), auth tokens (in-memory feature).

### Adding a New Runtime (After Hostaibot Refactoring)

1. Create `src/lib/runtime/newruntime-adapter.ts` — implement all 12 interface methods
2. Add `NEWRUNTIME` to `RuntimeType` enum in `schema.prisma`
3. Add 3 lines to `registry.ts`
4. Run `npx prisma migrate dev`

**Zero consumer file changes needed.**

---

## 4. Gap Analysis — Adapter Schema (All Fixed)

> [!NOTE]
> These schema mismatches were in `aiui-adapter.ts`. **All 7 have been fixed** as part of the hostaibot protocol-driven refactoring (verified: 1200/1240 tests pass).

| Gap | Was | Now | Status |
|-----|-----|-----|--------|
| G-A1: Port | 8080 | `port: 8082` | ✅ Fixed |
| G-A2: Model path | top-level `model:` | `provider: { model: "gpt-4o-mini" }` | ✅ Fixed |
| G-A2b: API key | `api_key` in config | Removed — env var `OPENAI_API_KEY` (in `.bashrc`) | ✅ Fixed |
| G-A3: auth_token | `server.auth_token` | Removed — AIUI auth is feature-driven | ✅ Fixed |
| G-A4: Channel format (`buildConfig`) | `{token: "..."}` flat | `{platform, config: {bot_token}, enabled, auto_start}` | ✅ Fixed |
| G-A5: Channel format (`syncChannelConfig`) | Same flat format | Same nested format | ✅ Fixed |
| G-A6: Health status | Expected `"healthy"` | Maps CLI success → `"pass"` | ✅ Fixed |
| G-A7: CLI command | `"health"` | `"health-check"` | ✅ Fixed |

---

## 5. Gap Analysis — AIUI Side (Validated)

> [!NOTE]
> All 5 proposed gaps were validated against the actual codebase. **Only 1 was real** — it has been fixed.

### G-U1: Config Hot-Reload Skips Channels — ✅ FIXED

**Was real**: `_on_config_reload()` in [server.py L1239](file:///Users/praison/PraisonAIUI/src/praisonaiui/server.py#L1239) reloaded agents and skills but NOT channels. The `_channels` module-level dict was never refreshed.

**Fix applied**: Added channel reload block to `_on_config_reload()` — clears `_channels`, re-loads from config store, resets `_auto_started` flag so changed channels auto-start on next API request. Follows the same pattern as agents/skills.

```python
# Added to _on_config_reload():
from praisonaiui.features.channels import (
    _channels, _CHANNELS_SECTION, ChannelsFeature,
)
from praisonaiui.features._persistence import load_section
updated = load_section(_CHANNELS_SECTION)
_channels.clear()
_channels.update(updated)
ChannelsFeature._auto_started = False
```

render_diffs(file:///Users/praison/PraisonAIUI/src/praisonaiui/server.py)

### G-U2: No Graceful Shutdown — ❌ NOT A REAL GAP

**Why**: AIUI runs via `uvicorn.run()` ([cli.py L507](file:///Users/praison/PraisonAIUI/src/praisonaiui/cli.py#L507)). Uvicorn already handles `SIGTERM` gracefully — it stops accepting new connections, waits for in-flight requests, then exits cleanly. No custom handler needed.

### G-U3: No Pre-Provisioned Auth Token — ❌ NOT A REAL GAP

**Why**: `AUTH_ENFORCE` is **off by default** (env var opt-in, [server.py L1060](file:///Users/praison/PraisonAIUI/src/praisonaiui/server.py#L1060)). In managed containers, simply don't set `AUTH_ENFORCE=true`. No AIUI code change needed.

### G-U4: Health Endpoint Missing Metadata — ❌ NOT A REAL GAP

**Why**: `/api/dashboard` ([server.py L375-390](file:///Users/praison/PraisonAIUI/src/praisonaiui/server.py#L375-L390)) already returns `uptime_seconds`, `version`, `stats`, `provider_health`, `agents`. The adapter can call this richer endpoint. `/health` is intentionally lightweight for probes.

### G-U5: Dockerfile Hardening — ❌ NOT A REAL GAP

**Why**: The [Dockerfile](file:///Users/praison/PraisonAIUI/Dockerfile) **already has**:
- `HEALTHCHECK` with `curl -f http://localhost:${AIUI_PORT}/health`
- `AIUI_PORT=8082` env var
- `curl` installed for health probes
- Proper multi-stage build

---

## 6. Remediation Plan

### Phase 1: Adapter Schema — ✅ Complete

All 7 adapter fixes (G-A1 through G-A7) were implemented as part of the hostaibot protocol-driven refactoring. Verified with 1200/1240 tests passing.

### Phase 2: AIUI Side — ✅ Complete

| Gap | Status | Notes |
|-----|--------|-------|
| G-U1: Channel hot-reload | ✅ **Fixed** | Added channel reload to `_on_config_reload()` in `server.py` |
| G-U2: Graceful shutdown | ❌ Not real | Uvicorn handles SIGTERM natively |
| G-U3: Admin token | ❌ Not real | AUTH_ENFORCE is off by default |
| G-U4: Health metadata | ❌ Not real | `/api/dashboard` already has all metadata |
| G-U5: Dockerfile | ❌ Not real | Already has HEALTHCHECK + curl |

> [!NOTE]
> OpenAI API key is delivered via env var (e.g. in `.bashrc`), not config.yaml. AIUI reads `OPENAI_API_KEY` from environment — the adapter should NOT write it to config.

---

## 7. Risk Summary

### Blockers — All Cleared ✅

| Risk | Side | Status |
|------|------|--------|
| Channel config wrong shape | Adapter | ✅ Fixed (G-A4/A5) |
| Health always fails (port + status) | Adapter | ✅ Fixed (G-A1/A6) |
| Model not found (wrong path) | Adapter | ✅ Fixed (G-A2) |
| API key ignored | Adapter | ✅ Fixed (G-A2 — now via env var) |

### Non-Blocking

| Risk | Side | Status |
|------|------|--------|
| Channels not reloaded on hot-write | AIUI | ✅ **Fixed** (G-U1) |
| Connections dropped on restart | Not real | Uvicorn handles graceful shutdown |
| Can't manage with auth enforced | Not real | AUTH_ENFORCE is off by default |

### Safe

| Assertion | Evidence |
|-----------|----------|
| OpenClaw unaffected | 1200/1240 tests pass, zero regressions |
| Config.yaml structure unchanged | Schemaless `YAMLConfigStore`, no validation |
| Protocol methods work | `parseConfig`/`serializeConfig`/`containerUser` tested |
| 3rd runtime pluggable | Only adapter + enum + registry needed |

# Knowledge Embedding Model Configuration

Source: https://ui.praison.ai/docs/features/knowledge-embeddings

# Knowledge Embedding Model Configuration

Knowledge / RAG search uses vector **embeddings**. The default embedding model is
`text-embedding-3-small`. Many OpenAI keys or projects do not have access to that
model (organization tier, model allowlist, or regional restrictions), which caused
knowledge search to silently degrade to local substring matching.

PraisonAIUI now makes this failure mode configurable and observable.

## Configure the embedding model

Set an accessible model via environment variable:

```bash
export AIUI_EMBEDDING_MODEL=text-embedding-ada-002
```

`OPENAI_EMBEDDING_MODEL` is also honoured as a fallback if `AIUI_EMBEDDING_MODEL`
is not set.

## Fallback chain

The OpenAI-compatible `/v1/embeddings` endpoint tries the requested (or default)
model first, then each model in the fallback chain if the primary returns a
`model_not_found` / 403 access error:

```bash
export AIUI_EMBEDDING_FALLBACK_MODELS="text-embedding-ada-002,text-embedding-3-small"
```

If every candidate is inaccessible, the endpoint returns `503` with an actionable
`model_not_found` error instead of a generic `500`.

## Observing degraded search

`GET /api/knowledge/status` reports embedding availability:

```json
{
  "total": 12,
  "backend": "SDKKnowledgeManager",
  "status": "degraded",
  "embedding": {"available": false, "error": "Project does not have access to model `text-embedding-3-small`"},
  "warnings": ["Embedding model unavailable; knowledge search degraded to local text matching. Set AIUI_EMBEDDING_MODEL to an accessible model."]
}
```

`POST /api/knowledge/search` indicates whether results came from vector search or a
degraded local fallback:

```json
{
  "results": [],
  "count": 0,
  "search_mode": "fallback",
  "warning": "Vector search unavailable: Project does not have access to model text-embedding-3-small. Set AIUI_EMBEDDING_MODEL=text-embedding-ada-002 or enable embedding models in your provider project."
}
```

A dashboard can show a warning banner whenever `search_mode == "fallback"` or
`embedding.available == false`.

## Model reference

| Model | Notes |
|-------|-------|
| `text-embedding-3-small` | Default — best cost/quality when available |
| `text-embedding-3-large` | Higher quality — may also be restricted |
| `text-embedding-ada-002` | Legacy — widely available on older projects |

# Plugin Marketplace

Source: https://ui.praison.ai/docs/features/marketplace

# Plugin Marketplace

Browse, search, install, and manage **plugins** from a registry. Supports local plugin discovery with a swappable backend for remote registries.

## Quick Start

```bash
# List available plugins
curl http://localhost:8083/api/marketplace/plugins

# Search for plugins
curl -X POST http://localhost:8083/api/marketplace/search \
  -H "Content-Type: application/json" \
  -d '{"query":"search"}'

# Install a plugin
curl -X POST http://localhost:8083/api/marketplace/install \
  -H "Content-Type: application/json" \
  -d '{"plugin_id":"web_search"}'
```

## How It Works

```mermaid
graph TD
    A["Plugin Registry"] --> B{"MarketplaceProtocol"}
    B --> C["LocalMarketplaceManager"]
    C --> D["Built-in Catalog\n(4 plugins)"]
    C --> E["Installed Plugins\n(in-memory)"]
    B --> F["Future: RemoteMarketplaceManager\n(PyPI, npm, etc.)"]
```

The marketplace uses a **protocol-driven** architecture. The default `LocalMarketplaceManager` ships with a built-in catalog of common plugins. Custom implementations can connect to remote registries.

## Built-in Plugins

| Plugin | Category | Description |
|--------|----------|-------------|
| `web_search` | tools | Search the web using DuckDuckGo |
| `code_executor` | tools | Execute Python code in sandbox |
| `file_manager` | tools | Read, write, and manage files |
| `memory_plugin` | memory | Persistent agent memory with ChromaDB |

## REST API

| Endpoint | Method | Description |
|----------|--------|-------------|
| `/api/marketplace/plugins` | GET | List all plugins |
| `/api/marketplace/search` | POST | Search plugins by query |
| `/api/marketplace/install` | POST | Install a plugin |
| `/api/marketplace/uninstall` | POST | Uninstall a plugin |
| `/api/marketplace/plugins/{id}` | GET | Get plugin details |

### POST /api/marketplace/install

```json
// Request
{"plugin_id": "web_search"}

// Response
{"status": "installed", "plugin": "web_search"}
```

### POST /api/marketplace/search

```json
// Request
{"query": "search", "limit": 20}

// Response
{"results": [{"id": "web_search", "name": "Web Search", "category": "tools", ...}], "count": 1}
```

# Media Analysis

Source: https://ui.praison.ai/docs/features/media-analysis

# Media Analysis

**Image understanding, OCR, and object detection** powered by VisionAgent — analyze uploaded images and documents.

## Quick Start

```bash
# List analysis capabilities
curl http://localhost:8083/api/media/capabilities

# Analyze an image
curl -X POST http://localhost:8083/api/media/analyze \
  -H "Content-Type: application/json" \
  -d '{"url":"https://example.com/photo.jpg","prompt":"What is in this image?"}'

# Extract text (OCR)
curl -X POST http://localhost:8083/api/media/ocr \
  -H "Content-Type: application/json" \
  -d '{"url":"https://example.com/document.png"}'
```

## How It Works

```mermaid
graph TD
    A["Image Input\n(URL or base64)"] --> B{"VisionAnalysisManager"}
    B --> C{"SDK Available?"}
    C -->|Yes| D["praisonaiagents\nVisionAgent / OCRAgent"]
    C -->|No| E["Simulated Mode\n(metadata only)"]
    D --> F["Image Description\nOCR Text\nObject Detection"]
```

The media analysis feature uses the **VisionAgent** and **OCRAgent** from the PraisonAI SDK when available. Without the SDK, it returns simulated responses to allow frontend development without API keys.

### Capabilities

| Capability | Description |
|------------|-------------|
| `image_description` | Natural language description of image contents |
| `ocr` | Extract text from images and documents |
| `object_detection` | Identify objects in images |
| `image_qa` | Answer questions about image contents |

## Configuration

```python
from praisonaiui.features.media_analysis import VisionAnalysisManager, set_analysis_manager

# Default: auto-detects SDK availability
set_analysis_manager(VisionAnalysisManager())
```

## REST API

| Endpoint | Method | Description |
|----------|--------|-------------|
| `/api/media/analyze` | POST | Analyze an image |
| `/api/media/ocr` | POST | Extract text via OCR |
| `/api/media/capabilities` | GET | List analysis capabilities |

### POST /api/media/analyze

```json
// Request
{"url": "https://example.com/photo.jpg", "prompt": "What is in this image?"}
// or
{"base64_data": "iVBORw0KGgo...", "mime_type": "image/png"}

// Response (SDK available)
{"analysis": "The image shows a sunset over mountains...", "status": "success", "provider": "sdk"}

// Response (simulated)
{"analysis": "[Simulated] Image analysis for: https://example.com/photo.jpg",
 "status": "simulated", "provider": "fallback",
 "note": "Install praisonaiagents for real analysis"}

// Response (no image → 400)
{"error": "No image provided", "status": "error"}
```

### POST /api/media/ocr

```json
// Request
{"url": "https://example.com/document.png"}

// Response
{"text": "Extracted text from the document...", "status": "success", "provider": "sdk"}
```

# Message Elements

Source: https://ui.praison.ai/docs/features/message-elements

# Message Elements

PraisonAIUI supports rich inline message elements for displaying images, PDFs, videos, audio, files, and code blocks within chat messages.

## Element Types

### 1. Image Elements

Display images with thumbnail and click-to-zoom functionality.

```python
from praisonaiui import Message

msg = Message("Check out this chart:")
msg.add_image(
    url="https://example.com/chart.png",
    name="Sales Chart",
    alt="Monthly sales chart showing growth",
    display="inline"  # or "side", "page"
)
await msg.send()
```

**Properties:**
- `url` (required): Image URL

- `display` (optional): Display mode - "inline" (default), "side", "page"
- `width` (optional): Fixed width in pixels
- `height` (optional): Fixed height in pixels

### 2. PDF Elements

Display PDF documents with inline viewer or link to open in new tab.

```python
msg.add_pdf(
    url="https://example.com/report.pdf",
    name="Quarterly Report",
    display="inline"  # Shows PDF viewer inline
)
```

**Properties:**
- `url` (required): PDF URL

- `display` (optional):
  - `"inline"`: Embedded PDF viewer (600px height)
  - `"side"`: Smaller embedded viewer (400px height)
  - `"page"`: Link to open in new tab

### 3. Video Elements

Display videos with native HTML5 video player.

```python
msg.add_video(
    url="https://example.com/demo.mp4",
    name="Product Demo",
    controls=True,  # Show video controls
    autoplay=False  # Don't autoplay
)
```

**Properties:**
- `url` (required): Video URL
- `name` (optional): Display name
- `controls` (optional): Show video controls (default: True)
- `autoplay` (optional): Auto-play video (default: False)
- `loop` (optional): Loop video (default: False)

### 4. Audio Elements

Display audio with native HTML5 audio player.

```python
msg.add_audio(
    url="https://example.com/clip.mp3",
    name="Audio Clip",
    controls=True
)
```

**Properties:**
- `url` (required): Audio URL
- `name` (optional): Display name
- `controls` (optional): Show audio controls (default: True)
- `autoplay` (optional): Auto-play audio (default: False)
- `loop` (optional): Loop audio (default: False)

### 5. File Elements

Display downloadable files with file type icons and size information.

```python
msg.add_file(
    url="https://example.com/data.csv",
    name="Data Export",
    size=1024000,  # Size in bytes
    mime_type="text/csv"
)
```

**Properties:**
- `url` (required): File download URL
- `name` (optional): Display name
- `size` (optional): File size in bytes
- `mime_type` (optional): MIME type for file type detection

### 6. Code Elements

Display syntax-highlighted code blocks with copy functionality.

```python
msg.add_code(
    content='print("Hello, World!")',
    language="python",
    name="Hello World Example"
)
```

**Properties:**
- `content` (required): Code content
- `language` (optional): Programming language for syntax highlighting
- `name` (optional): Display name

## Display Modes

All elements support three display modes:

- **`inline`** (default): Full width, normal display
- **`side`**: Smaller size, suitable for sidebars
- **`page`**: Full page width, maximum size

## Size Limits

- **File elements**: Maximum 100MB per file
- **Code elements**: Maximum 1MB per code block
- **Images**: No size limit (browser-dependent)

## Accessibility Features

- **Images**: Alt text support, keyboard navigation for zoom
- **PDFs**: Proper ARIA labels and roles
- **Videos/Audio**: Native browser accessibility
- **Files**: Icon-based file type recognition
- **Code**: Copy button with keyboard support

## Low-Level API

For advanced use cases, you can use the low-level element API:

```python
from praisonaiui.schema.models import ImageElement

# Create typed element
element = ImageElement(
    url="https://example.com/image.png",
    alt="Description",
    display="inline"
)

# Add to message
msg.elements.append(element)
```

## Legacy Support

The new element system maintains backward compatibility with existing message properties:

- `message.images` (still supported)
- `message.files` (still supported)
- New `message.elements` takes precedence when both are present

This ensures existing code continues to work while providing a migration path to the new standardized element system.

## Agent-generated images (streaming)

When an agent or tool **creates** an image during a chat run, the UI receives `message_element` events over WebSocket/SSE and renders them inline. This uses the same element dict shape as above but is driven by the [RunEvent protocol](../concepts/providers.md), not only `Message.send()`.

See **[Image Preview in Chat](./image-preview-chat.md)** for the full architecture: detection (`media_utils`), provider bridge, persistence, and swappable backends.

# Model Fallback

Source: https://ui.praison.ai/docs/features/model-fallback

# Model Fallback

Configure **model fallback chains** for high availability — if the primary LLM fails, automatically try the next model in the chain.

![Model Fallback Configuration](../images/model-fallback.png)

## Quick Start

```bash
# List available models
curl http://localhost:8083/api/models

# Set a fallback chain
curl -X PUT http://localhost:8083/api/models/fallback \
  -H "Content-Type: application/json" \
  -d '{"models": ["gpt-4o", "gpt-4o-mini", "claude-3-5-sonnet"]}'
```

## How It Works

```mermaid
graph TD
    A["User Request"] --> B["gpt-4o (Primary)"]
    B -->|Success| C["Return Response"]
    B -->|Failure| D["gpt-4o-mini (Fallback 1)"]
    D -->|Success| C
    D -->|Failure| E["claude-3-5-sonnet (Fallback 2)"]
    E -->|Success| C
    E -->|Failure| F["Error: All models failed"]
```

When a request is sent:

1. Try the **primary model** first
2. If it fails (rate limit, timeout, error), try **fallback 1**
3. Continue down the chain until a model responds
4. If all models fail, return an error

## Model Discovery

The `ModelFallbackManager` tries to discover models automatically:

1. **LiteLLM** — If installed, reads `litellm.model_list` for configured models
2. **Static catalog** — Falls back to common models (gpt-4o, gpt-4o-mini, claude-3-5-sonnet, gemini-2.0-flash)

## Configuration

```python
from praisonaiui.features.model_fallback import ModelFallbackManager

mgr = ModelFallbackManager()

# Get available models
models = mgr.get_models()
# [{"id": "gpt-4o", "provider": "openai"}, ...]

# Set fallback chain
mgr.set_fallback_chain(["gpt-4o", "gpt-4o-mini"])

# Get current chain
chain = mgr.get_fallback_chain()
# ["gpt-4o", "gpt-4o-mini"]
```

## REST API

| Endpoint | Method | Description |
|----------|--------|-------------|
| `/api/models` | GET | List available models + current fallback chain |
| `/api/models/fallback` | PUT | Set the fallback chain |

### List Models

```bash
curl http://localhost:8083/api/models
```

```json
{
  "models": [
    {"id": "gpt-4o", "provider": "openai"},
    {"id": "gpt-4o-mini", "provider": "openai"},
    {"id": "claude-3-5-sonnet", "provider": "anthropic"},
    {"id": "gemini-2.0-flash", "provider": "google"}
  ],
  "fallback_chain": ["gpt-4o", "gpt-4o-mini"]
}
```

# Navigation

Source: https://ui.praison.ai/docs/features/navigation

# Navigation

Configure automatic and manual navigation generation.

## Auto Navigation

By default, navigation is generated from your docs folder structure:

```yaml
content:
  docs:
    nav:
      mode: "auto"
      sort: "filesystem"
```

### Sort Options

| Mode | Description |
|------|-------------|
| `filesystem` | Use file order on disk |
| `alpha` | Alphabetical by title |
| `date` | By creation date |

## Navigation Tree

Generated navigation follows this format:

```json
{
  "items": [
    {
      "title": "Getting Started",
      "slug": "getting-started",
      "children": [
        { "title": "Installation", "slug": "getting-started/installation" },
        { "title": "Quick Start", "slug": "getting-started/quickstart" }
      ]
    }
  ]
}
```

## Collapsible Sections

```yaml
content:
  docs:
    nav:
      collapsible: true
      maxDepth: 4
```

## Manual Navigation

For full control, use manual mode:

```yaml
content:
  docs:
    nav:
      mode: "manual"
      items:
        - title: "Home"
          href: "/docs"
        - title: "Guides"
          children:
            - title: "Installation"
              href: "/docs/installation"
```

# PraisonAI package integration

Source: https://ui.praison.ai/docs/features/praisonai-package-integration

# PraisonAI package integration

How **PraisonAIUI** (`aiui`) connects to **`praisonai-package`** — the agent runtime, gateway, and CLI. For generic UI hosting see [Agent UI host](agent-ui-host.md).

## Division of labour

| Layer | Repo | Role |
|-------|------|------|
| Agent runtime | `praisonai-agents` | `Agent`, tools, memory, streaming |
| Gateway, jobs, CLI | `praisonai` | WebSocket `/ws`, `/api/v1/runs`, `praisonai claw` |
| Dashboard UI | **PraisonAIUI** | `dashboard.js`, `@aiui.page`, layout protocol |
| Work tracking | `praisonai-platform` | Issues API (optional board data source) |

Canonical app: `praisonai-package` → `src/praisonai/praisonai/claw/default_app.py`.

## Deployment shapes

### 1. Single process — `praisonai claw` (recommended)

```bash
praisonai claw   # → aiui run claw/default_app.py, default :8082
```

```text
Browser → create_app() (same process)
        → PraisonAISessionDataStore (sessions)
        → PraisonAIProvider (@aiui.reply / agents)
        → Built-in dashboard views
```

Use when: local dev, full dashboard, agents registered in Python.

### 2. Unified — `AIUIGateway`

```python
from praisonaiui.integration import AIUIGateway
gateway = AIUIGateway(port=8080)
gateway.register_agent(agent)
await gateway.start()   # create_app() + WebSocket /ws
```

Use when: you need **WebSocket gateway protocol** and dashboard on **one port**.

### 3. Split — gateway + UI

| Service | Default port | Endpoints |
|---------|--------------|-----------|
| `praisonai gateway start` | 8765 | `ws://…/ws`, `/health`, `/info` |
| `praisonai claw` or `aiui run` | 8082 | Dashboard, `/run` SSE, `/api/*` |

Use when: gateway runs headless; UI is a separate process. Point chat at gateway via provider config or run `AIUIGateway` instead.

## Wiring checklist

```python
import praisonaiui as aiui
from praisonai.ui._aiui_datastore import PraisonAISessionDataStore

aiui.set_datastore(PraisonAISessionDataStore())
aiui.set_style("dashboard")
aiui.set_pages(["chat", "agents", "sessions", "config"])
aiui.set_dashboard(modules=["jobs"], sidebar=True, page_header=True)

# Optional: point jobs UI at package jobs server paths
aiui.set_jobs_api(api_base="/api/v1/runs", backend="praisonai")
```

Or via host bootstrap:

```python
from praisonai.integration.host_app import configure_host, create_host_app

configure_host(pages=[...], modules=["jobs"], agents=[...])
app = create_host_app()
```

## API surface

### Chat and agents (dashboard)

| Endpoint | Purpose |
|----------|---------|
| `POST /run` | Stream agent run (SSE) |
| `GET /sessions`, `POST /sessions` | Session CRUD |
| `GET /agents`, `/api/agents/definitions` | Agent list / CRUD |
| `GET /api/health` | Sidebar health slot |

### Async jobs — two paths

| Backend | Base path | When |
|---------|-----------|------|
| **aiui** `JobsFeature` | `/api/jobs` | Default; in-process job store |
| **praisonai** jobs server | `/api/v1/runs` | Standalone `praisonai jobs` / FastAPI router |

Configure the dashboard jobs view:

```python
aiui.set_jobs_api(api_base="/api/jobs", backend="aiui")       # default
aiui.set_jobs_api(api_base="/api/v1/runs", backend="praisonai")
```

`/ui-config.json` exposes `jobs: { apiBase, backend }` for `jobs.js`.

**Response shapes:** both return `{ jobs, total }`. Praison uses `job_id`; aiui uses `id`. The jobs view normalises either field.

| Action | aiui | praisonai |
|--------|------|-----------|
| List | `GET /api/jobs` | `GET /api/v1/runs` |
| Detail | `GET /api/jobs/{id}` | `GET /api/v1/runs/{id}` |
| Cancel | `POST /api/jobs/{id}/cancel` | `POST /api/v1/runs/{id}/cancel` |
| Stream | `GET /api/jobs/{id}/stream` | `GET /api/v1/runs/{id}/stream` |
| Delete | `DELETE /api/jobs/{id}` | Not on package router |

**Split jobs server (optional):** proxy aiui `/api/jobs/*` to an external jobs host:

```python
aiui.set_jobs_proxy("http://127.0.0.1:9000")  # forwards to /api/v1/runs/*
aiui.set_jobs_api(api_base="/api/jobs", backend="aiui")
```

Use when the dashboard and jobs server run on different ports. Prefer `set_jobs_backend("praisonai")` when the browser can call `/api/v1/runs` on the same origin.

### REST invoke (automation)

| Path | Use |
|------|-----|
| `POST /api/v1/agents/{id}/invoke` | Sync invoke (n8n, scripts) — **package** `agent_invoke.py` |
| `POST /run` | Streaming chat — **dashboard** chat page |

Same agents if registered on both surfaces; different protocols.

### Discovery (package serve)

| Endpoint | Purpose |
|----------|---------|
| `GET /__praisonai__/discovery` | Serve-mode capability discovery |
| `GET /health`, `GET /info` | Gateway liveness and metadata |
| `GET /api/gateway/status` | aiui gateway feature status |

See **Feature Explorer** page in dashboard for live probes.

## Parallel UI protocols (not dashboard replacements)

Under `praisonaiagents/ui/`:

| Protocol | Purpose |
|----------|---------|
| **A2A** | Agent cards, `/.well-known/agent.json`, external agent hosts |
| **AG-UI** | CopilotKit-style event stream (`POST /agui`) |
| **A2UI** | Declarative surfaces in chat/canvas |

Dashboard shell remains the ops console for `praisonai claw`. Use A2A/AG-UI/A2UI when embedding in other products.

## Two plugin systems

| System | Location | Purpose |
|--------|----------|---------|
| **Agent plugins** | `~/.praisonai/plugins/` | Python agent extensions (`praisonaiagents.plugins`) |
| **Dashboard plugins** | `~/.praisonai/dashboard-plugins/` | JS tabs + `manifest.json` for aiui shell |

Do not mix folders. Agent plugins extend runtime; dashboard plugins extend UI tabs only.

## Optional modules

```python
aiui.set_dashboard(modules=["jobs", "auth", "api"])
```

Loads `jobs.js`, `auth.js`, `api.js` into the plugin chain and maps them in `BUILTIN_VIEWS`. Enable only what your deployment exposes.

## Board / work tracking

Neither repo ships Hermes-style Kanban. Options:

1. **`aiui.board()`** — columns from `@aiui.page` handler (jobs by status, custom data).
2. **`praisonai-platform` issues** — map issue `status` → board columns (see `examples/python/platform-board/`). Set `PRAISONAI_PLATFORM_URL` and `PRAISONAI_PLATFORM_WORKSPACE_ID` (default workspace `default`); issues are fetched from `GET /api/v1/workspaces/{workspace_id}/issues`.
3. **`dashboard-plugins`** — rich JS via `registerView` + `sdk.createBoard`.

Advanced board UX (drag-drop, WebSocket sync) is **deferred** — use polling via `sdk.createBoard({ pollMs })` or a custom plugin.

## Smoke checklist

After `praisonai claw` or `aiui run` with package bridges:

- [ ] `GET /api/health` → sidebar footer shows healthy
- [ ] Chat page sends message, streams reply
- [ ] Sessions page lists `~/.praisonai/sessions/` data
- [ ] Agents page CRUD (if agents registered)
- [ ] Jobs page (if `modules` includes `jobs` and jobs API configured)
- [ ] Explorer probes `/health`, `/ui-config.json`, `/api/dashboard/plugins`
- [ ] Auth/API pages (if `modules` includes `auth` / `api`)

# Protocol Architecture Reference

Source: https://ui.praison.ai/docs/features/protocol-architecture

# Protocol Architecture Reference

All feature modules in PraisonAIUI implement a **Protocol ABC** pattern for type-safe, swappable backends.

## Pattern

```
FeatureProtocol (ABC)              <- abstract interface
  ├── SDKFeatureManager            <- wraps praisonaiagents SDK
  └── SimpleFeatureManager         <- in-memory fallback
get_feature_manager()              <- SDK-first factory
```

## Batch 1: Full SDK Wrappers

| File | Protocol | SDK Class | Fallback | Getter |
|------|----------|-----------|----------|--------|
| `guardrails.py` | `GuardrailProtocol` | `SDKGuardrailManager` | `SimpleGuardrailManager` | `get_guardrail_manager()` |
| `tracing.py` | `TracingProtocol` | `SDKTracingManager` | `SimpleTracingManager` | `get_tracing_manager()` |
| `eval.py` | `EvalProtocol` | `SDKEvalManager` | `SimpleEvalManager` | `get_eval_manager()` |
| `approvals.py` | `ApprovalProtocol` | `SDKApprovalManager` | `SimpleApprovalManager` | `get_approval_manager()` |

## Batch 2: SDK Wrappers + Refactored Stores

| File | Protocol | SDK Class | Fallback | Getter |
|------|----------|-----------|----------|--------|
| `security.py` | `SecurityProtocol` | `SDKSecurityManager` | `SimpleSecurityManager` | `get_security_manager()` |
| `telemetry.py` | `TelemetryProtocol` | `SDKTelemetryManager` | `SimpleTelemetryManager` | `get_telemetry_manager()` |
| `jobs.py` | `JobStoreProtocol` | `SDKJobStore` | `SimpleJobStore` | `get_job_store()` |
| `agents.py` | `AgentRegistryProtocol` | `SDKAgentRegistry` | `SimpleAgentRegistry` | `get_agent_registry()` |

## Batch 3: Formalized ABCs

| File | Protocol | Notes |
|------|----------|-------|
| `sessions_ext.py` | `SessionProtocol` | Formalized existing SDK-first pattern |
| `schedules.py` | `ScheduleProtocol` | Formalized existing SDK-first pattern |
| `channels.py` | `ChannelProtocol` | SDK gap: no channel management API |
| `usage.py` | `UsageProtocol` | SDK gap: no token/cost tracking API |
| `logs.py` | `LogProtocol` | UI-only by design |
| `auth.py` | `AuthProtocol` | SDK gap: no auth API |
| `config_runtime.py` | `ConfigProtocol` | UI-only by design |
| `nodes.py` | `NodeProtocol` | SDK gap: no node/cluster API |

## Pre-existing

| File | Protocol | Notes |
|------|----------|-------|
| `memory.py` | `MemoryProtocol` | P0 fix: SDK-first default |
| `skills.py` | `BaseFeatureProtocol` | P1 fix: `get_tool_catalog()` |

## SDK Gaps

Features where `praisonaiagents` SDK lacks backend support:

| Feature | Gap | Recommendation |
|---------|-----|----------------|
| **Usage** | No token/cost tracking API | Add `UsageTracker` to `praisonaiagents.telemetry` |
| **Auth** | No authentication module | Add `praisonaiagents.auth` with key/session persistence |
| **Nodes** | No node/cluster management | Add `praisonaiagents.nodes` for node discovery |
| **Channels** | No channel management API | Add `praisonaiagents.channels` with `ChannelStore` |
| **Config** | No runtime config persistence | Add `praisonaiagents.config` with file-backed store |

## Building & Extending — Key Rules

### Agent Registration API

> [!CAUTION]
> The old `create_agent()` function and `_agent_definitions` dict were **removed**. All agent registration now goes through the Protocol ABC.

```python
# ✅ Correct — use the registry singleton
from praisonaiui.features.agents import get_agent_registry

registry = get_agent_registry()

# Create
registry.create({
    "name": "MyAgent",
    "description": "Does X",
    "instructions": "You are ...",
    "model": "gpt-4o-mini",
    "icon": "🤖",
})

# List & check
existing = registry.list_all()  # returns list of dicts
agent = registry.get("agent-id-here")

# Update / Delete
registry.update("agent-id", {"model": "gpt-4o"})
registry.delete("agent-id")
```

### Frontend Manifest Requirement

> [!IMPORTANT]
> The React frontend **always** fetches 3 JSON files before rendering, regardless of style:
> - `/ui-config.json` — must return `{"style": "dashboard"}` (or `"chat"`, `"agents"`, etc.)
> - `/docs-nav.json` — sidebar nav (can be `{"items": []}` for non-docs modes)
> - `/route-manifest.json` — URL routing (can be `{}` for non-docs modes)
>
> If any of these 404, the user sees **"Failed to load manifests"** and the dashboard never renders.

In `server.py`, `create_app()` provides dynamic fallback handlers for these. If you are running
via `AIUIGateway`, these handlers are included automatically. If writing a custom server, ensure
these routes exist.

### Style System

The `style` field in `/ui-config.json` controls which React component renders:

| Style | Component | Use Case |
|-------|-----------|----------|
| `"docs"` | Three-column docs layout | Documentation sites |
| `"dashboard"` | Full sidebar + pages | Feature management dashboard |
| `"chat"` | Chat-focused interface | Chat-only applications |
| `"agents"` | Agent selector + chat | Multi-agent interfaces |
| `"playground"` | Split-pane playground | Agent experimentation |
| `"custom"` | Flexible layout | Custom configurations |

Set via Python: `aiui.set_style("dashboard")`

### Feature Protocol — How to Add a New Feature

Every feature follows the same 4-step pattern:

1. **Define the Protocol ABC** — abstract methods for the capability
2. **Implement `SimpleXxxManager`** — in-memory fallback, zero dependencies
3. **Implement `SDKXxxManager`** — wraps `praisonaiagents` SDK (if available)
4. **Provide `get_xxx_manager()`** — factory function, SDK-first with fallback

```python
# Minimal feature skeleton
from abc import ABC, abstractmethod

class MyProtocol(ABC):
    @abstractmethod
    def do_thing(self, data): ...

class SimpleMyManager(MyProtocol):
    def do_thing(self, data):
        return {"status": "ok", "data": data}

_manager = None

def get_my_manager() -> MyProtocol:
    global _manager
    if _manager is None:
        try:
            # Try SDK-first
            from praisonaiagents.my_module import MySDKClass
            _manager = SDKMyManager()
        except ImportError:
            _manager = SimpleMyManager()
    return _manager
```

### Data Persistence

- **Sessions**: JSON files in `~/.praisonaiui/sessions/{session_id}.json`
- **Memory**: Auto-stored from chat (every user + assistant message → `short` type memory via SDK `Memory.store_short_term()`). Searchable via `/api/memory/search`. Filterable by `session_id` via `/api/memory/session/{id}`
- **Knowledge**: Stored via `/api/knowledge` (text) or `/api/knowledge/add-file` (file ingest). Searched via `/api/knowledge/search`. Context auto-injected into chat prompts when relevant entries exist. Uses SDK `Knowledge` class with RAG pipeline when `[knowledge]` extras installed
- **Agents**: In-memory by default; `SimpleAgentRegistry` persists to data file if `set_data_file()` called
- **Schedules**: `FileScheduleStore` from `praisonaiagents` SDK persists to disk
- **Config**: Runtime config via `/api/config_runtime`, not persisted by default

### Common Pitfalls

| Pitfall | Solution |
|---------|----------|
| `ImportError: _agent_definitions` | Use `get_agent_registry()` instead |
| "Failed to load manifests" in browser | Ensure `/ui-config.json` route exists and returns valid JSON with `style` field |
| Port already in use | `lsof -ti :PORT \| xargs kill -9` before starting |
| Chat returns no response | Check `OPENAI_API_KEY` is set in the running process |
| `praisonai_agents: false` in `/health` | Install `praisonaiagents` package |
| Features show 0 count | Features auto-register on import; check `server.py` initializes them |

---

## Naming Convention

All feature classes MUST follow the `{Name}Feature` pattern:

| ✅ Correct | ❌ Incorrect |
|-----------|------------|
| `SchedulesFeature` | `PraisonAISchedules` |
| `KnowledgeFeature` | `PraisonAIKnowledge` |
| `AgentsCrudFeature` | `PraisonAIAgentsFeature` |
| `MemoryFeature` | `PraisonAIMemory` |

### Rules

1. **Class name**: `{Name}Feature` — PascalCase, ends with `Feature`
2. **`feature_name`**: `lowercase_snake` — this is the registry key, **never change it**
3. **Module file**: `{name}.py` — matches `feature_name`
4. **Backward-compat aliases**: old `PraisonAI{Name}` names are kept as aliases

### Example

```python
# In features/schedules.py

class SchedulesFeature(BaseFeatureProtocol):
    feature_name = "schedules"  # Registry key — never change
    
    def routes(self):
        return [Route("/api/schedules", ...)]

# Backward-compat alias (at end of file)
PraisonAISchedules = SchedulesFeature
```

### Why This Convention?

- **AIUI is a universal UI framework**, not PraisonAI-specific
- **Class names signal framework identity** to third-party developers
- **`feature_name` stays unchanged** for backward compatibility with existing configs
- **Aliases preserve imports** for existing code using old names

# Protocol Versioning

Source: https://ui.praison.ai/docs/features/protocol-versioning

# Protocol Versioning

**WebSocket protocol negotiation** between client and server — ensures compatibility and graceful degradation.

## Quick Start

```bash
# Get protocol info
curl http://localhost:8083/api/protocol

# Negotiate version
curl -X POST http://localhost:8083/api/protocol/negotiate \
  -H "Content-Type: application/json" \
  -d '{"client_version": "1.0.0"}'
```

## How It Works

```mermaid
sequenceDiagram
    participant C as Client
    participant S as Server

    C->>S: POST /api/protocol/negotiate {client_version: "1.0.0"}
    S->>S: Check major version compatibility
    S-->>C: {compatible: true, server_version: "1.0.0", event_types: [...]}
    C->>S: Connect WS /api/chat/ws
    Note over C,S: Both sides use compatible event types
```

## Version Compatibility

The protocol uses **semantic versioning** — clients and servers are compatible if they share the **same major version**:

| Client Version | Server Version | Compatible? |
|---------------|----------------|-------------|
| 1.0.0 | 1.0.0 | ✅ Yes |
| 1.2.0 | 1.0.0 | ✅ Yes (same major) |
| 2.0.0 | 1.0.0 | ❌ No (different major) |

## Event Types

The protocol defines these standard event types:

| Event Type | Direction | Description |
|-----------|-----------|-------------|
| `chat` | Client → Server | User sends a message |
| `chat_abort` | Client → Server | Abort an active run |
| `ping` / `pong` | Both | Keepalive |
| `run_content` | Server → Client | Delta token (streaming) |
| `run_completed` | Server → Client | Run finished |
| `run_error` | Server → Client | Run failed |
| `tool_call_started` | Server → Client | Tool execution began |
| `tool_call_completed` | Server → Client | Tool returned result |
| `reasoning` | Server → Client | Agent reasoning/thinking |

## REST API

| Endpoint | Method | Description |
|----------|--------|-------------|
| `/api/protocol` | GET | Get protocol version and supported event types |
| `/api/protocol/negotiate` | POST | Check client compatibility |

### Protocol Info

```bash
curl http://localhost:8083/api/protocol
```

```json
{
  "version": "1.0.0",
  "event_types": ["chat", "run_content", "run_completed", "tool_call_started", ...],
  "features": {
    "streaming": true,
    "tool_calls": true,
    "reasoning": true,
    "abort": true
  }
}
```

### Negotiate

```bash
curl -X POST http://localhost:8083/api/protocol/negotiate \
  -H "Content-Type: application/json" \
  -d '{"client_version": "1.0.0"}'
```

```json
{
  "compatible": true,
  "server_version": "1.0.0",
  "client_version": "1.0.0"
}
```

# Feature Protocols

PraisonAIUI uses a **protocol-driven architecture** to wire features into the server. Every feature module implements the `BaseFeatureProtocol` ABC, which auto-registers API routes, CLI commands, and health checks.

## Architecture

```

## Quick Start

### List All Features

```bash
# CLI
aiui features list --server http://127.0.0.1:8000

# API
curl http://127.0.0.1:8000/api/features
```

### Python — Create a Custom Feature

```python
from praisonaiui.features._base import BaseFeatureProtocol
from starlette.routing import Route
from starlette.requests import Request
from starlette.responses import JSONResponse

class MyFeature(BaseFeatureProtocol):
    feature_name = "my_feature"
    feature_description = "Does something cool"

    @property
    def name(self) -> str:
        return self.feature_name

    @property
    def description(self) -> str:
        return self.feature_description

    def routes(self):
        return [Route("/api/my-feature", self._handler, methods=["GET"])]

    async def _handler(self, request: Request) -> JSONResponse:
        return JSONResponse({"hello": "world"})

# Register it
from praisonaiui.features import register_feature
register_feature(MyFeature())
```

## BaseFeatureProtocol API

Every feature module must implement:

| Method | Return | Required | Description |
|--------|--------|----------|-------------|
| `name` | `str` | ✓ | Unique feature identifier |
| `description` | `str` | ✓ | Human-readable description |
| `routes()` | `List[Route]` | ✓ | Starlette routes to mount |
| `cli_commands()` | `List[dict]` | ○ | CLI command metadata |
| `health()` | `dict` | ○ | Health check (default: `{"status": "ok"}`) |
| `info()` | `dict` | ○ | Metadata for `/api/features` listing |

### `cli_commands()` Format

```python
def cli_commands(self):
    return [{
        "name": "my-feature",        # Typer subcommand group name
        "help": "My feature things",  # Group help text
        "commands": {
            "list": {"help": "List items", "handler": self._cli_list},
            "add":  {"help": "Add item",  "handler": self._cli_add},
        },
    }]
```

## Registry Functions

```python
from praisonaiui.features import (
    register_feature,        # Register a feature instance
    get_features,            # Get all registered features (dict)
    get_feature,             # Get a single feature by name
    auto_register_defaults,  # Register all 10 built-in features
)
```

## Route Ordering

> **Important:** When defining routes with parametric paths (e.g., `/{id}`), always place literal paths (e.g., `/log`, `/runs`) **before** the parametric route. Starlette matches routes in order, and a parametric route will capture literal segments as parameter values.

```python
# ✓ Correct — literal before parametric
Route("/api/hooks/log", self._log, methods=["GET"]),
Route("/api/hooks/{hook_id}", self._get, methods=["GET"]),

# ✗ Wrong — "log" captured as hook_id
Route("/api/hooks/{hook_id}", self._get, methods=["GET"]),

## Integration Example

```python
"""Custom analytics feature — tracks page views."""
from praisonaiui.features._base import BaseFeatureProtocol
from starlette.routing import Route
from starlette.requests import Request
from starlette.responses import JSONResponse

_views = {}

class AnalyticsFeature(BaseFeatureProtocol):

            Route("/api/analytics", self._list, methods=["GET"]),
            Route("/api/analytics/track", self._track, methods=["POST"]),
        ]

    async def _list(self, request):

# Progressive Web App (PWA)

Source: https://ui.praison.ai/docs/features/pwa

# Progressive Web App (PWA)

Install PraisonAIUI as a **native-like app** on any device — manifest, service worker, and offline support.

## Quick Start

```bash
# Get PWA manifest
curl http://localhost:8083/manifest.json

# Get service worker
curl http://localhost:8083/sw.js

# Check PWA configuration
curl http://localhost:8083/api/pwa/config
```

## How It Works

The PWA feature automatically serves three endpoints:

| URL | Purpose |
|-----|---------|
| `/manifest.json` | Web Application Manifest for installability |
| `/sw.js` | Service Worker for caching and offline support |
| `/api/pwa/config` | PWA configuration for frontend consumption |

### Service Worker Strategy

The service worker uses a **cache-first** strategy for the app shell and a **network-first** strategy for navigation:

1. **Install**: Pre-caches the root URL and health endpoint
2. **Activate**: Cleans up old caches
3. **Fetch**: Navigation requests fall back to cached root for offline support

## Configuration

```python
from praisonaiui.features.pwa import DefaultPWAManager, set_pwa_manager

# Customize PWA settings
mgr = DefaultPWAManager(
    name="My AI Assistant",
    short_name="AI",
    theme_color="#1a1a2e",
    bg_color="#16213e",
    display="standalone"
)
set_pwa_manager(mgr)
```

## Generated Manifest

```json
{
    "name": "PraisonAI",
    "short_name": "AI",
    "start_url": "/",
    "display": "standalone",
    "theme_color": "#1a1a2e",
    "background_color": "#16213e",
    "icons": [
        {"src": "/api/pwa/icon/192", "sizes": "192x192", "type": "image/png"},
        {"src": "/api/pwa/icon/512", "sizes": "512x512", "type": "image/png"}
    ],
    "orientation": "portrait-primary",
    "scope": "/"
}
```

## REST API

| Endpoint | Method | Description |
|----------|--------|-------------|
| `/manifest.json` | GET | Web Application Manifest |
| `/sw.js` | GET | Service Worker JavaScript |
| `/api/pwa/config` | GET | PWA configuration details |

# Replay

Source: https://ui.praison.ai/docs/features/replay

# Replay

**PraisonAI Replay** shows a recorded agent run as a story: who did what, when, why, and
at what cost. It works for finished runs and for runs that are still going.

## Record a run, then open it

```bash
praisonai replay view agents.yaml      # records the run and opens Replay on it
```

or from Python:

```python
from praisonai.replay import record

with record(live=True):
    team.start()
```

Every recorded run is a file `<id>.jsonl` in the traces folder. Replay reads it from
`$PRAISONAI_TRACES_DIR`, else `$PRAISON_HOME/traces`, else `~/.praison/traces`.

To open aiui on Replay yourself:

```bash
aiui run "$(python -c 'import praisonaiui.replay_app as m; print(m.__file__)')" \
    --style dashboard --host 127.0.0.1 --port 8090
# then open http://127.0.0.1:8090/replay?run=<id>
```

`/#/replay?run=<id>` works too. In a full dashboard, Replay is in the sidebar under
**Control**.

## Watch a run live: the Run button

For learning, demos and debugging, open a page with a **Run** button. Each click records
a new run, and the page draws it as it happens:

```python
from praisonai.replay import watch

watch(flow, input="solar sails")   # an Agent, AgentTeam, AgentFlow or agents.yaml
```

```bash
praisonai replay watch agents.yaml
```

On the **Map**, each step and agent shows where the run is: dashed means not reached,
blue (pulsing) means running now, green means done and red means failed. After a run,
**▶ Play** moves through it again one step at a time, and the map rewinds with it. One
run goes at a time. Each run of a team starts its tasks afresh; an Agent keeps its chat
history between runs.

## Show progress inside your own app

`create_replay_app()` is the same view as a small ASGI app, without the dashboard. Mount
it in any FastAPI or Starlette app:

```python
from praisonai.replay import record, replay_app

app.mount("/replay", replay_app())         # read-only: shows recorded runs

# wherever your app starts work:
with record(run_id, live=True):
    team.start()
```

Then show one run, live, in your page, for example in an `<iframe>`:

```html
<iframe src="/replay/?run=RUN_ID" style="width:100%;height:640px"></iframe>
```

| URL | Shows |
|---|---|
| `/replay/` | The run list and the selected run |
| `/replay/?run=<id>` | Only that run, no list. A run that has not started yet is waited for. |

`replay_app(team)` adds the Run box to the mounted page. Without the PraisonAI wrapper,
pass any `run(input, run_id)` callable to `praisonaiui.features.replay.create_replay_app`;
it must record the run under `run_id`. For a page you build yourself, the view is one
module:

```html
<div id="progress"></div>
<script type="module">
  import { render } from "/replay/replay.js";
  render(document.getElementById("progress"), { base: "/replay", run: "RUN_ID", approve: false });
</script>
```

`render()` options: `base` (where the API is mounted), `run` (show only this run),
`runner` (`{input, placeholder, ask}` to show the Run box) and `approve` (`false` hides
the approve and deny buttons; the embedded app has no approvals API, so answer approvals
where your app asks for them).

Anyone who can reach the mounted app can read the runs, and with a runner can start one.
Keep it on localhost or behind your app's login. `POST /api/replay/run` only accepts
`Content-Type: application/json`, so another website cannot start a run from a visitor's
browser.

## What you see

| Part | What it shows |
|---|---|
| **Runs** | Recorded runs, newest first. A run that is still being written has a **Live** badge. |
| **Timeline** (default) | One lane per agent, plus **Manager** and **You**. Time runs left to right. LLM calls and tool calls are blocks in their agent's lane. Arrows show hand-offs, delegation, routing and approval requests. Parallel branches get their own sub-lanes. A call or step repeated back to back is one block marked ×N. Tasks and steps run across the top. |
| **Map** | The team or flow as a graph, drawn from the graph recorded at the start of the run and fitted to the page (−, Fit and + zoom; drag to pan). Agents that took part but are not in the graph, for example after a hand-off to an agent outside the team, appear in an **Outside the team** group with their hand-offs. Older recordings without a graph get a "who talked to whom" map built from the events. Each node shows its state at the cursor: dashed means not reached, blue means running, green means done (×N when it ran more than once) and red means failed; the node the cursor is on has a bold outline. |
| **What happened** | One plain sentence per step, for example *"Researcher asked web_search for 'solar sail facts' — 1.2 s, $0.002."* Hovering or focusing a sentence highlights its block, and the other way round. |
| **Details** | Three tabs for the selected step. **What happened**: when, who, how long, cost, tokens, output. **Why**: only what the recording holds, such as the input given to a tool, the context passed in a hand-off and its reason, the manager's task snapshot, the route a step chose, and an approval's decision and where an automatic approval came from. **Raw JSON**: the events themselves. |
| **Cost & latency** | Adds a bar under each block (taller and darker means more cost, or more time) and per-agent totals in the lane labels. |

Shapes always carry meaning as well as colour: agents are circles, tools are rounded
rectangles, you are a diamond and the manager is a square. In each lane, LLM calls sit on
the top row and that agent's tool calls on a thinner row under them, so a long LLM call
never hides its tools. Labels that do not fit end in "…"; hover or focus a block to see the
whole label.

The **Theme** menu follows your system's light or dark setting by default; choose Light or
Dark to override it. On a phone the run list, timeline and steps stack in one column.

## Moving through a run

Replay opens at the end of the run, so you see everything. Move the cursor to replay it:
anything after the cursor is drawn as an outline.

| Key | Action |
|---|---|
| ← → | Previous / next step |
| ↑ ↓ | Previous / next step in the step list; previous / next node in the map |
| Home / End | First / last step |
| Enter or Space | Open the focused block or node |
| ← → in the tabs | Switch between What happened, Why and Raw JSON |

The scrubber under the timeline does the same with a mouse or touch, and **▶ Play** steps
through on its own. On a live run the
cursor follows new events; if you step back, **Jump to live** takes you to the latest.

## Approving from Replay

When an agent asks for approval and the run uses aiui's approval store, a **Waiting for
you** card appears above the timeline:

- **Approve** or **Deny**, with an optional reason.
- **Edit arguments…** opens the arguments as JSON (taken from the server, not the redacted
  recording when the server has them). The JSON must be an object; mistakes are shown
  as you type. **Approve with these arguments** sends them as `modified_args`.

These buttons call `POST /api/approvals/{id}/approve` and `/deny`. The agent waits until
you answer, and is denied if nobody answers before the approval timeout.

## Sharing a run as one file

`praisonai replay export RUN --format html` writes a single HTML file with the run and
this viewer inside. It needs no server and no network. Approvals cannot be answered from
an exported file.

## HTTP API

| Endpoint | Returns |
|---|---|
| `GET /api/replay/runs` | `[{run_id, session_id, path, started_at, ended_at?, status, kind, name, agents, events, cost_usd, live}]`, newest first |
| `GET /api/replay/runs/{id}/events?after_seq=N` | `{events, graph, run}`; `after_seq` keeps only events with a larger `sequence_num`; `wait=1` answers `{events: [], graph: null, run: null}` instead of 404 for a run that has not started yet |
| `GET /api/replay/runs/{id}/stream` | Server-sent events: `event: ctx` per trace event (with `id:` = `sequence_num`), `ping` every 15 s, `end` once the run has finished and gone quiet for 2 s. Honours `after_seq` and `Last-Event-ID`. |

With a runner (`create_replay_app(run=...)`), `POST /api/replay/run` with
`{"input": "..."}` starts a run and returns `{run_id}` (409 while one is going).

Run ids must match `^[A-Za-z0-9._-]+$`. Replay never writes trace files itself. Half-written last lines, unknown fields and unknown event types are skipped
safely, and schema 1.0 recordings still open.

The **Traces** page reads the same files: each run is a trace, and its spans come from
matching start and end events.

# SEO

Source: https://ui.praison.ai/docs/features/seo

# SEO

Built-in SEO for documentation sites — sitemap, robots, llms.txt, per-page meta tags, and crawlable static HTML.

## Configuration

Top-level `seo` block in `aiui.template.yaml`:

```yaml
seo:
  siteUrl: "https://ui.praison.ai"
  titleTemplate: "%s | %s"
  defaultImage: "/icon.svg"
  robots:
    index: true
    follow: true
  twitter:
    handle: "@yourhandle"
```

`siteUrl` is required for absolute canonical URLs, sitemap, and social tags.

## Build outputs

`aiui build` automatically generates:

| File | Purpose |
|------|---------|
| `sitemap.xml` | All doc URLs with `lastmod` dates |
| `robots.txt` | Crawl rules + sitemap pointer |
| `llms.txt` | AI crawler index ([llmstxt.org](https://llmstxt.org)) |
| `llms-full.txt` | Full markdown export for AI tools |
| `docs/**/*.html` | Per-route HTML with meta tags + crawl nav |
| `.nojekyll` | GitHub Pages Jekyll bypass |

No extra flags are needed — SEO files are emitted whenever `content.docs` is configured.

## Page-level overrides

Use frontmatter on any markdown page:

```markdown
---
title: "Custom Page Title"
description: "Custom meta description for search snippets"
noindex: true
---

# Page Content
```

If `description` is omitted, the first paragraph is used automatically.

## Per-page HTML includes

Each route HTML file contains:

- `<link rel="canonical">` (absolute HTTPS)
- `<meta name="description">`
- Open Graph tags (`og:title`, `og:description`, `og:url`, `og:type`, `og:image`)
- Twitter Card tags
- JSON-LD `TechArticle` schema
- Static `<nav>` with links to every doc page (for non-JS crawlers)
- `<noscript>` pre-rendered page content

## Runtime (SPA navigation)

When users navigate via the sidebar, React updates title, canonical, OG, Twitter, robots, and JSON-LD to match the current page.

## Deploy

GitHub Pages deploy runs via the **Deploy Docs** workflow on every push to `main`. Submit your sitemap in [Google Search Console](https://search.google.com/search-console):

```
https://your-domain.com/sitemap.xml
```

# Session Management

Source: https://ui.praison.ai/docs/features/sessions

# Session Management

PraisonAIUI provides full session management for chat conversations — create, switch, view history, and delete sessions.

## Quick Start

```bash
# Start server with persistent sessions
aiui run app.py --datastore json

# Sessions persist to ~/.praisonaiui/sessions/
```

## Data Persistence Options

| Mode | Flag | Persists? | Best For |
|------|------|-----------|----------|
| Memory | `--datastore memory` (default) | ❌ Lost on restart | Development, testing |
| JSON Files | `--datastore json` | ✅ `~/.praisonaiui/sessions/` | Single-user, local |
| JSON (custom path) | `--datastore json:/path/to/dir` | ✅ Custom directory | Custom setups |
| Custom DB | Implement `BaseDataStore` | ✅ Your database | Production |

## REST API

### List Sessions
```bash
curl http://127.0.0.1:8000/sessions
```

### Create Session
```bash
curl -X POST http://127.0.0.1:8000/sessions
```

### Get Session Details
```bash
curl http://127.0.0.1:8000/sessions/<session_id>
```

### Get Message History
```bash
curl http://127.0.0.1:8000/sessions/<session_id>/runs
```

### Delete Session
```bash
curl -X DELETE http://127.0.0.1:8000/sessions/<session_id>
```

### Send Message
```bash
curl -X POST http://127.0.0.1:8000/run \
  -H "Content-Type: application/json" \
  -d '{"message":"Hello", "session_id":"<session_id>"}'
```

## CLI Commands

Every API endpoint has a CLI equivalent:

```bash
aiui sessions list                    # List all sessions
aiui sessions create                  # Create a new session
aiui sessions get <session_id>        # Get session details
aiui sessions messages <session_id>   # View message history
aiui sessions delete <session_id>     # Delete a session
aiui health-check                     # Server health check
```

Use `--server` to target a different server:
```bash
aiui sessions list --server http://localhost:3000
```

## Custom Data Store

Implement `BaseDataStore` for any database (SQLite, PostgreSQL, Redis, MongoDB, etc.):

```python
from praisonaiui.datastore import BaseDataStore

class PostgresDataStore(BaseDataStore):
    def __init__(self, dsn: str):
        self.dsn = dsn
        # ... set up connection pool

    async def list_sessions(self) -> list[dict]:
        # SELECT id, created_at, updated_at, message_count FROM sessions
        ...

    async def get_session(self, session_id: str) -> dict | None:
        # SELECT * FROM sessions WHERE id = ?
        ...

    async def create_session(self, session_id: str = None) -> dict:
        # INSERT INTO sessions ...
        ...

    async def delete_session(self, session_id: str) -> bool:
        # DELETE FROM sessions WHERE id = ?
        ...

    async def add_message(self, session_id: str, message: dict) -> None:
        # INSERT INTO messages ...
        ...

    async def get_messages(self, session_id: str) -> list[dict]:
        # SELECT * FROM messages WHERE session_id = ? ORDER BY timestamp
        ...

    async def close(self) -> None:
        # Close connection pool
        ...
```

Register before the server starts:

```python
# In your app.py:
from praisonaiui.server import set_datastore

store = PostgresDataStore("postgresql://user:pass@localhost/db")
set_datastore(store)
```

## Backend Modes

| Mode | Command | Transport | Session Source |
|------|---------|-----------|---------------|
| Standalone (default) | `aiui run app.py` | SSE over HTTP | DataStore |
| PraisonAI | `aiui run app.py --backend praisonai` | WebSocket | WebSocketGateway |

In **standalone** mode, sessions are managed by the configurable DataStore.
In **praisonai** mode, sessions are managed by the `WebSocketGateway` from the praisonai package.

# Standalone vs Integrated

Source: https://ui.praison.ai/docs/features/standalone-vs-integrated

# Standalone vs Integrated

This page summarises the expected install and runtime shape for PraisonAIUI in both modes.

## Install Matrix

| Mode | Package install | Runtime dependency | Behaviour |
| --- | --- | --- | --- |
| Standalone UI | `pip install praisonaiui` | Optional SDK packages absent | Uses built-in local managers and fallbacks |
| Integrated (PraisonAI) | `pip install praisonaiui praisonai praisonaiagents` | SDK and wrapper available | Uses injected backends and SDK-aware managers |

## Backend injection (integrated mode)

When hosted via `praisonai.integration.host_app.configure_host()`, the wrapper calls `praisonaiui.backends.set_backend()` for:

| Backend key | Feature area |
| --- | --- |
| `hooks` | Hooks dashboard |
| `workflows` | Workflow runs |
| `usage_query` / `usage_sink` | Usage analytics |
| `approvals_pending` / `approvals_policies` | HITL approvals |
| `jobs_store` / `jobs_executor` | Async jobs (optional) |
| `channel_bot` | Channel bots (optional) |
| `tool_resolver` | Agent tool name resolution (optional) |

Detect integrated mode in code: `praisonaiui.backends.is_integrated_mode()`.

## Documented SDK gaps (local fallback)

These features work standalone with in-memory stores. Health responses include `sdk_gap: true`:

| Feature | Gap | Standalone behaviour |
| --- | --- | --- |
| **nodes** | No cluster API in praisonaiagents | In-memory node registry |
| **auth** | No SDK auth module | In-memory API keys / sessions |
| **channels** | Bot runtime via praisonai wrapper | In-memory channel registry; bots need `praisonai[bot]` |
| **jobs** | Mock success only when standalone and agent missing | Integrated mode fails job instead of fake success |
| **realtime** | WebRTC needs `OPENAI_API_KEY` | Mock stream standalone; degraded error when integrated without key |
| **media / code** | SDK paths optional | `status: simulated` standalone; `status: degraded` integrated on failure |

View gaps in the dashboard sidebar footer (`GET /api/health` → `sdk_gaps` array).

## Practical Differences

- **Session/data handling**: standalone uses UI datastore fallback; integrated aligns with SDK-backed stores.
- **Feature backends**: standalone keeps in-memory/mock behaviour; integrated routes through injected factories.
- **Lifecycle hooks**: integrated mode can subscribe to SDK hooks (handoff, MCP lifecycle, tracing/eval stores).

## Recommendation

Use standalone mode for local UI-only workflows. Use integrated mode when you need shared runtime state with PraisonAI agents, tools, tracing, approvals, and schedules.

## Live Integration Tests (Example 17 Server)

### Setup
```
Server: examples/python/17-three-column-demo/app.py
Mode: Gateway (3 agents: Researcher, Writer, Coder)
Port: 8082
```

### Endpoint Results: 45/47 HTTP 200

All 37 feature endpoints, plus protocol, config, health, sessions, and OpenAI API returned HTTP 200. Two JSON key checks showed false negatives because the SPA returns HTML for some routes when `Accept: application/json` header isn't explicitly set — both underlying HTTP responses were 200.

## Pre-Existing Test Failures (Not Caused by Standardization)

**411 passed / 18 failed / 5 errors** (ignoring 10 module-level collection errors)

The 18 test failures are **pre-existing** and unrelated to standardization:

| Test File | Failures | Root Cause |
|-----------|----------|------------|
| `test_server.py` (4) | `_callbacks` empty, session list | Server callback registration not initialized |
| `test_gateway_fixes.py` (3) | register_agent, list_agents | StandaloneGateway API changes (pre-existing) |
| `test_endpoints.py` (6) | reply dispatch, sessions, thinking | Integration tests expect running server |
| `test_fixed_features.py` (1) | memory clear | Stale state from prior runs |
| `test_feature_*.py` (10 errors) | Module-level assertion failures | Tests run assertions at import time against live server state |

> **None of these failures are caused by the standardization changes.** The 12 new tests (7 doctor + 5 data-dir) all pass.

# Steps / Chain-of-Thought

Source: https://ui.praison.ai/docs/features/steps

# Steps / Chain-of-Thought

Visualize agent reasoning and tool calls as collapsible, nested steps in the chat interface.

## Basic Usage

```python
import praisonaiui as aiui

@aiui.reply
async def agent_response(message):
    # Tool call step
    async with aiui.Step(name="🔧 Tool: web_search", type="tool_call") as step:
        await step.stream_token("Input: { query: 'rust async ecosystem 2026' }")
        # ... perform actual tool call
        await step.stream_token("Output: [ 10 search results ]")
    
    # Reasoning step  
    async with aiui.Step(name="🧠 Reasoning: Synthesizing results", type="reasoning") as step:
        await step.stream_token("I see three major async runtimes...")
    
    return "Rust's async ecosystem in 2026 is dominated by..."
```

## Nested Steps

Steps can be nested to show hierarchical reasoning:

```python
async with aiui.Step(name="Multi-agent research", type="reasoning") as parent:
    await parent.stream_token("Starting research task...")
    
    # Sub-agent step
    async with aiui.Step(name="🤖 Sub-agent: Technical Analysis", type="sub_agent", parent=parent) as sub:
        await sub.stream_token("Analyzing technical details...")
        
        # Tool called by sub-agent
        async with aiui.Step(name="🔧 Tool: code_search", type="tool_call", parent=sub) as tool:
            await tool.stream_token("Searching codebase...")
```

## Step Types

Common step patterns:

```python
# Tool calls
async with aiui.Step(name="🔧 Tool: database_query", type="tool_call") as step:
    await step.stream_token("Querying user database...")

# Reasoning/thinking  
async with aiui.Step(name="🧠 Reasoning: Plan evaluation", type="reasoning") as step:
    await step.stream_token("Evaluating different approaches...")

# Sub-agents
async with aiui.Step(name="🤖 Sub-agent: Code reviewer", type="sub_agent") as step:
    await step.stream_token("Reviewing code quality...")

# Retrieval
async with aiui.Step(name="📚 Retrieval: Knowledge search", type="retrieval") as step:
    await step.stream_token("Searching knowledge base...")

# Custom
async with aiui.Step(name="⚡ Custom: Data processing", type="custom") as step:
    await step.stream_token("Processing large dataset...")
```

## Frontend Visualization

Steps appear in the chat as collapsible panels showing:

- **Icons** indicating step type (🔧 🧠 🤖 📚 ⚡)
- **Expandable content** with input/output details
- **Nested hierarchy** for complex reasoning chains
- **Real-time updates** as steps stream content

## API Reference

### `aiui.Step(name, type="reasoning", parent=None, metadata={})`

**Parameters:**
- `name` (str): Display name for the step
- `type` (StepType, optional): Step type - one of `"tool_call"`, `"reasoning"`, `"sub_agent"`, `"retrieval"`, `"custom"` (default: `"reasoning"`)
- `parent` (Step, optional): Parent step for nesting
- `metadata` (dict, optional): Additional step metadata

**Methods:**
- `async stream_token(token)`: Stream content to the step
- Context manager protocol: `async with step: ...`

### `@aiui.step(name, type="reasoning", **metadata)`

**Decorator Parameters:**
- `name` (str): Display name for the step
- `type` (StepType, optional): Step type (default: `"reasoning"`)
- `**metadata`: Additional metadata to include with the step

**Usage:**
```python
@aiui.step("🔧 Tool: web_search", type="tool_call")
async def web_search(query: str):
    # Function will be wrapped in Step context
    result = await search_web(query)
    return result
```

### Events Emitted

Steps emit these `RunEventType` events:
- `REASONING_STARTED`: Step begins (includes `step_type`, `parent_id`, `metadata`)
- `REASONING_STEP`: Content streamed (includes `step_type`)
- `REASONING_COMPLETED`: Step finishes (includes `step_type`, `duration`, `error`, `metadata`)

# UI Styles

Source: https://ui.praison.ai/docs/features/styles

# UI Styles

PraisonAIUI supports 6 distinct UI styles that control how your application looks and behaves. Styles are **auto-detected** from your code — you usually don't need to set them manually.

## Available Styles

| Style | Layout | Description |
|-------|--------|-------------|
| `chat` | `ChatLayout` | Conversational AI interface with sessions, streaming, profiles |
| `agents` | `AgentUILayout` | Multi-agent playground with tabbed agent/session sidebar |
| `playground` | `PlaygroundLayout` | Side-by-side input/output panels for prompt testing |
| `dashboard` | `DashboardLayout` | Admin panel with custom pages |
| `docs` | `ThreeColumnLayout` | Documentation site with sidebar + TOC |
| `custom` | User-defined | Full control over layout |

## Auto-Detection

PraisonAIUI automatically detects the best style from your Python code — no flags needed:

```bash
aiui run app.py    # style is inferred automatically
```

### How It Works

After loading your `app.py`, the CLI inspects which callbacks and agents you registered:

| Your Code Uses | Detected Style |
|---------------|----------------|
| `@profiles` + `register_agent()` | `agents` |
| `@page` decorators | `dashboard` |
| `@reply` only | `chat` |

### Example: Auto-Detected as `agents`

```python
import praisonaiui as aiui

# These two signals trigger auto-detection of "agents" style
aiui.register_agent("Coder", {"name": "Coder", "instructions": "..."})

@aiui.profiles
async def get_profiles():
    return [
        {"name": "Coder", "icon": "💻", "default": True},
        {"name": "Writer", "icon": "✍️"},
    ]

@aiui.reply
async def on_message(message):
    await aiui.say(f"Echo: {message}")
```

```bash
aiui run app.py
# Output: ℹ️ Auto-detected style: agents
```

## Explicit Style Setting

### From the CLI

Override auto-detection with `--style`:

```bash
aiui run app.py --style chat          # force chat layout
aiui run app.py --style agents        # force agents layout
aiui run app.py --style playground    # force playground layout
```

### From Python Code

Use `aiui.set_style()` for styles that can't be auto-detected (e.g., `playground`):

```python
import praisonaiui as aiui

aiui.set_style("playground")  # takes priority over auto-detection

@aiui.reply
async def on_message(message):
    await aiui.say(f"Echo: {message}")
```

## Priority Order

When multiple sources specify a style, this priority chain applies:

1. **CLI `--style`** flag (highest — always wins)
2. **`aiui.set_style()`** in Python code
3. **Auto-detection** from registered callbacks/agents
4. **Default:** `chat`

## Chat Layout Modes

The `chat` style supports additional layout modes for embedding:

| Mode | Description |
|------|-------------|
| `fullscreen` | Full-page chat (default) |
| `sidebar` | Fixed right-side panel |
| `bottom-right` | Floating widget (bottom-right corner) |
| `bottom-left` | Floating widget (bottom-left) |
| `top-right` | Floating widget (top-right) |
| `top-left` | Floating widget (top-left) |

## YAML Configuration

For YAML-based apps, set the style in your config:

```yaml
name: My App
instructions: You are a helpful assistant.
style: agents

profiles:
  - name: "General"
    icon: "🤖"
    default: true
  - name: "Coder"
    icon: "💻"
```

```bash
aiui run chat.yaml    # reads style from YAML
```

# Subagent Tree View

Source: https://ui.praison.ai/docs/features/subagent-tree

# Subagent Tree View

Visualize **agent hierarchies** — see which agents spawn subagents, track their status, and monitor the full execution tree.

![Subagent Tree View](../images/subagent-tree.png)

## Quick Start

```bash
# Get the subagent tree for a session
curl http://localhost:8083/api/subagents/my-session

# List all spawns across sessions
curl http://localhost:8083/api/subagents
```

## How It Works

```mermaid
graph TD
    A["Orchestrator"] --> B["Researcher"]
    A --> C["Writer"]
    A --> D["Coder"]
    B --> E["Web Searcher"]
    C --> F["Editor"]
```

When agents spawn subagents during execution, each spawn is registered with the `SubagentManager`:

1. **Parent agent** spawns a **child agent**
2. The spawn is recorded with session ID, timestamp, and status
3. A tree structure is built from spawn records
4. The tree can be queried per-session via the REST API

## Configuration

```python
from praisonaiui.features.subagents import SubagentManager

mgr = SubagentManager()

# Register a spawn event
spawn_id = mgr.register_spawn(
    parent_agent="orchestrator",
    child_agent="researcher",
    session_id="my-session",
)

# Get the tree
tree = mgr.get_tree("my-session")
# {
#   "session_id": "my-session",
#   "roots": [{"name": "orchestrator", "children": [{"name": "researcher", ...}]}],
#   "total_spawns": 1
# }
```

## REST API

| Endpoint | Method | Description |
|----------|--------|-------------|
| `/api/subagents` | GET | List all spawn events |
| `/api/subagents/{session_id}` | GET | Get tree for a session |

### Get Tree

```bash
curl http://localhost:8083/api/subagents/my-session
```

```json
{
  "session_id": "my-session",
  "roots": [
    {
      "name": "orchestrator",
      "children": [
        {"name": "researcher", "children": []},
        {"name": "writer", "children": [
          {"name": "editor", "children": []}
        ]}
      ]
    }
  ],
  "total_spawns": 3
}
```

# Theme System

Source: https://ui.praison.ai/docs/features/theme-system

# Theme System

Switch between **dark**, **light**, and **custom themes** using CSS custom properties — applied across all dashboard pages including chat.

![Theme Comparison](../images/theme-comparison.png)

## Quick Start

```bash
# Get current theme
curl http://localhost:8083/api/theme

# Switch to light mode
curl -X PUT http://localhost:8083/api/theme \
  -H "Content-Type: application/json" \
  -d '{"theme": "light"}'
```

## Built-in Themes

### Dark (Default)

| Variable | Value | Usage |
|----------|-------|-------|
| `--chat-bg` | `#0d1117` | Background |
| `--chat-text` | `#e6edf3` | Primary text |
| `--chat-user-bg` | `#1f6feb` | User message bubble |
| `--chat-assistant-bg` | `#161b22` | Assistant message bubble |
| `--chat-input-bg` | `#0d1117` | Input area |
| `--chat-border` | `#30363d` | Borders |
| `--chat-accent` | `#58a6ff` | Links and accents |
| `--chat-code-bg` | `#161b22` | Code blocks |

### Light

| Variable | Value | Usage |
|----------|-------|-------|
| `--chat-bg` | `#ffffff` | Background |
| `--chat-text` | `#1f2328` | Primary text |
| `--chat-user-bg` | `#ddf4ff` | User message bubble |
| `--chat-assistant-bg` | `#f6f8fa` | Assistant message bubble |
| `--chat-input-bg` | `#ffffff` | Input area |
| `--chat-border` | `#d1d9e0` | Borders |
| `--chat-accent` | `#0969da` | Links and accents |
| `--chat-code-bg` | `#f6f8fa` | Code blocks |

## Custom Themes

Register a custom theme from Python:

```python
from praisonaiui.features.theme import ThemeManager

mgr = ThemeManager()
mgr.register_theme("ocean", {
    "--chat-bg": "#001122",
    "--chat-text": "#e0f0ff",
    "--chat-user-bg": "#004488",
    "--chat-assistant-bg": "#002244",
    "--chat-input-bg": "#001122",
    "--chat-border": "#003366",
    "--chat-accent": "#66bbff",
    "--chat-code-bg": "#002244",
})
```

Or via API:

```bash
curl -X POST http://localhost:8083/api/theme/custom \
  -H "Content-Type: application/json" \
  -d '{
    "name": "ocean",
    "variables": {
      "--chat-bg": "#001122",
      "--chat-text": "#e0f0ff"
    }
  }'
```

## REST API

| Endpoint | Method | Description |
|----------|--------|-------------|
| `/api/theme` | GET | Get current theme and CSS variables |
| `/api/theme` | PUT | Set the active theme |
| `/api/theme/list` | GET | List all available themes |
| `/api/theme/custom` | POST | Register a custom theme |

## How CSS Variables Work

```mermaid
graph LR
    A["ThemeManager"] --> B["CSS Variables"]
    B --> C[":root { --chat-bg: #0d1117 }"]
    C --> D["chat.css uses var(--chat-bg)"]
    D --> E["All components themed"]
```

The theme system injects CSS custom properties into the `:root` element. All chat and dashboard CSS uses `var(--chat-*)` references, so switching themes instantly updates the entire UI.

```bash
# List available voices
curl http://localhost:8083/api/tts/voices

# Synthesize speech
curl -X POST http://localhost:8083/api/tts/synthesize \
  -H "Content-Type: application/json" \
  -d '{"text":"Hello from PraisonAI","voice":"default"}'
```

## How It Works

```mermaid
graph LR
    A["Text Input"] --> B{"TTSProtocol"}
    B --> C["BrowserTTSManager\n(Web Speech API)"]
    B --> D["OpenAITTSManager\n(API Key Required)"]
    C --> E["Client-side\nspeechSynthesis"]
    D --> F["Server-side\nMP3 Audio"]
```

**Default**: `BrowserTTSManager` — uses the browser's built-in Web Speech API, requires no API key, runs entirely client-side.

**Optional**: `OpenAITTSManager` — uses OpenAI's TTS API for higher-quality voices (alloy, echo, fable, onyx, nova, shimmer). Requires `openai` package and API key.

## Configuration

```python
from praisonaiui.features.tts import set_tts_manager, OpenAITTSManager

# Switch to OpenAI TTS (requires OPENAI_API_KEY)
set_tts_manager(OpenAITTSManager())
```

## REST API

| Endpoint | Method | Description |
|----------|--------|-------------|
| `/api/tts/voices` | GET | List available voices |
| `/api/tts/synthesize` | POST | Synthesize speech from text |

### GET /api/tts/voices

```json
{
    "voices": [
        {"id": "default", "name": "Default", "lang": "en-US"},
        {"id": "google-us", "name": "Google US English", "lang": "en-US"},
        {"id": "google-uk", "name": "Google UK English", "lang": "en-GB"}
    ],
    "count": 3
}
```

### POST /api/tts/synthesize

```json
// Request
{"text": "Hello from PraisonAI", "voice": "default"}

// Response (browser)
{
    "type": "browser_speech",
    "text": "Hello from PraisonAI",
    "voice": "default",
    "instruction": "Use window.speechSynthesis.speak(new SpeechSynthesisUtterance(text))"
}
```

# Video Studio

Source: https://ui.praison.ai/docs/features/video-studio

# Video Studio

The Video Studio integrates [PraisonAI Video](https://github.com/MervinPraison/praisonai-video) as an external Node render engine. PraisonAIUI provides the dashboard shell, project files, YAML editor, job UX, and HTTP proxying. The video engine handles parse, compile, lint, and MP4 export. **Agents live in PraisonAI (Chat + tools), not inside the renderer.**

## Prerequisites

1. Install PraisonAI Video CLI (`praisonai-video`) or run from the monorepo.
2. Start the engine sidecar (recommended):

```bash
praisonai-video serve --port 3921
```

3. Run the example app:

```bash
aiui run examples/python/video-studio/app.py
```

Open the **Video** tab, create a project, edit `scene.yaml`, and use Lint / Render.

For **Chat** to edit scenes, install `praisonaiagents` and set `OPENAI_API_KEY`. Optional: `VIDEO_STUDIO_PROJECT_ID` to target a specific project.

## Configuration

| Variable | Default | Purpose |
|----------|---------|---------|
| `VIDEO_ENGINE_URL` | `http://127.0.0.1:3921` | HTTP API base URL |
| `VIDEO_ENGINE_TOKEN` | (none) | Optional Bearer token forwarded to the engine |
| `PRAISONAI_PROJECTS_DIR` | `~/.praisonai/projects` | On-disk project roots |
| `PRAISONAI_VIDEO_CLI` | (auto-detect) | Path to `praisonai-video` or `dist/cli.js` for subprocess fallback |
| `VIDEO_STUDIO_PROJECT_ID` | (auto) | Active project for agent tools when not passed explicitly |
| `PRAISONAI_MODEL` | `gpt-4o-mini` | LLM for Video Editor agent in the example app |

Python API:

```python
from praisonaiui.video_config import set_video_engine

set_video_engine(url="http://127.0.0.1:3921", projects_dir="~/my-videos")
```

## Projects

Each project is a directory containing:

- `scene.yaml` — scene definition
- `scene.visual-test.yaml` — optional visual regression spec
- `.praisonai/project.json` — metadata
- `exports/` — rendered MP4 artefacts

## API routes

All routes are under `/api/video/`:

- `GET /health` — sidecar status
- `POST /lint`, `POST /compile` — scene validation
- `GET /preview-url`, `POST /preview/start` — preview iframe URL (CLI; dashboard preview hidden)
- `POST /render` — async render job (`type: video_render`); optional `backend` (`playwright` | `remotion`) overrides `scene.yaml` `render.backend`
- `GET /jobs/{id}` — job status and download URL
- `GET|POST /projects` — list and create projects
- `GET /projects/{id}/studio-refresh` — poll after agent tool updates (`refresh: true` once)

When the HTTP sidecar is unavailable, lint and render fall back to subprocess calls to `praisonai-video`.

## Dashboard plugin

The UI lives in `dashboard-plugins/video-studio/` (built-in) or `~/.praisonai/dashboard-plugins/video-studio/` for overrides. It uses `window.aiui.sdk.fetchJSON`.

**Frame-by-frame composition preview is hidden** in the dashboard (`SHOW_COMPOSITION_PREVIEW = false`) until serve preview + seek are reliable. Use **Render MP4** and the **Your video** player for output. Set the flag to `true` in `index.js` to re-enable the optional iframe scrubber.

After agent tool writes, the editor reloads via `video-studio:refresh` (custom event) or polling `studio-refresh`.

## Agent workflow (PraisonAI-first)

1. Open **Chat** with the Video Editor agent (example app registers tools when `praisonaiagents` is installed).
2. Agent calls `video_get_scene` / `video_update_scene` / `video_lint_scene` / `video_render_project` (same outcomes as UI buttons).
3. Video Studio tab picks up changes automatically.

Tools are defined in `praisonaiui/video_agent_tools.py`. For Cursor/Codex outside the UI, use the skill at `skills/praisonai-video/SKILL.md` in the PraisonAI Video repo.

### Optional render backends

Default is **Playwright** (no `render:` block in `scene.yaml`). Use Remotion only when required:

```yaml
render:
  backend: remotion   # needs Remotion licence + remotion-root export; lint will error on default YAML export
```

`video_render_project(backend="playwright")` overrides YAML for one agent run. Hyperframes is deferred.

## CLI parity

The text box edits the same `scene.yaml` the CLI uses. Equivalent commands (from the video repo):

```bash
praisonai-video project create "My video"
praisonai-video project lint <project-id>
praisonai-video project preview <project-id>
praisonai-video project test <project-id>
praisonai-video project render <project-id>
praisonai-video project reset <project-id>
```

Lint editor text without saving: `praisonai-video lint --stdin < scene.yaml`

See `docs/integrations/praisonaiui.md` in the PraisonAI Video repo for the full mapping table.

# BeautifulUI upstream pin record

Source: https://ui.praison.ai/docs/frontend/BEAUTIFULUI_UPSTREAM

# BeautifulUI upstream pin record

BeautifulUI is vendored (shadcn-style registry copy), **not** an npm dependency.
This file is the single source of truth for what upstream revision is vendored.
Update it in the **same PR** that adds or bumps any vendored component, and make
sure the frontend CI gate (issue #295) passes.

See [beautifului-adapter-architecture.md](./beautifului-adapter-architecture.md)
for the adapter boundary and folder layout.

## Pin

| Field | Value |
|-------|-------|
| Upstream repo | _TBD — record on first vendor_ |
| Git SHA | _TBD_ |
| Vendored on (date) | _TBD_ |
| Registry base URL | _TBD_ |
| License | MIT (kept in-tree) |

## Vendored components

Record one row per component the first time it is copied in.

| Component | Registry URL | SHA | Vendored path | Date |
|-----------|--------------|-----|---------------|------|
| _(none yet)_ | | | | |

## Upgrade checklist

1. Update the SHA / date / registry rows above.
2. Re-copy changed components into `src/frontend/src/agent-ui/vendors/beautifului/`.
3. Keep all upstream imports inside `src/agent-ui/` (adapter boundary rule).
4. Run the frontend build + adapter unit tests (frontend CI gate, #295).
5. Do **not** add a `beautiful-ui` entry to `package.json` dependencies.

# ADR: BeautifulUI adapter layer & upstream pin policy

Source: https://ui.praison.ai/docs/frontend/beautifului-adapter-architecture

# ADR: BeautifulUI adapter layer & upstream pin policy

**Status:** Accepted · **Issue:** [#294](https://github.com/MervinPraison/PraisonAIUI/issues/294)

## Context

BeautifulUI is **not** a semver npm library — it is distributed as shadcn-style
registry components that are copied into the consuming repo. PraisonAIUI must
integrate it without leaking upstream types or import paths across the codebase,
and without breaking when either side updates.

## Decision

Introduce a single **adapter boundary** between transport payloads and the UI,
and vendor BeautifulUI components behind that boundary.

```
Agent APIs (Python) ──► event bus / WS messages
                              │
                              ▼
                    Agent-UI adapter (src/agent-ui/adapter.ts)
                    (stable PraisonAIUI contracts)
                              │
                              ▼
              @praisonaiui/react re-exports
              (BeautifulUI vendored components)
                              │
                              ▼
         Dashboard / chat mount points (React islands, then full shell)
```

### 1. Folder layout

```
src/frontend/src/agent-ui/
├── contracts.ts        # Stable PraisonAIUI view models (the ONLY types consumers import)
├── adapter.ts          # Pure mappers: wire payload -> contracts
├── adapter.test.ts     # Unit tests (mock events -> props), node:test
├── index.ts            # Barrel: contracts + adapters + (later) vendored re-exports
└── vendors/
    └── beautifului/    # Vendored BeautifulUI components (added during migration)
```

**Rule:** BeautifulUI / upstream prop types must **never** be imported outside
`src/agent-ui/`. Consumers depend on `contracts.ts` only, so the vendored
implementation can be swapped later without touching call sites.

### 2. Adapter contracts

Internal, transport-agnostic types live in `contracts.ts`:

- `AgentStreamEvent` — normalized form of the WebSocket frames handled in
  `chat.js` (`run_started`, `run_content`, `tool_call_started`, …). Unknown
  frame `type`s degrade to `kind: 'unknown'` with `rawType` preserved instead
  of throwing, so new upstream events never break the UI.
- `ToolCallChipModel` — tool-call chip view model.
- `ApprovalPromptModel` — approval card view model, mapped from the
  `/api/approvals/pending` REST payload.

Mappers (`adapter.ts`): `mapChatEventToUi(frame)` and
`mapApprovalToCardProps(item)`. Both are **pure** and unit tested.

### 3. Vendoring & pin policy

| Mechanism | Purpose |
|-----------|---------|
| [`BEAUTIFULUI_UPSTREAM.md`](./BEAUTIFULUI_UPSTREAM.md) | Record git SHA, date, registry base URL for every vendored component |
| shadcn registry URLs | Per-component install, pinned in the upstream doc |
| **No** `dependencies.beautiful-ui` in `package.json` | Avoid a phantom npm package |

**Upgrade rule:** bump upstream **only** via a PR that updates
`BEAUTIFULUI_UPSTREAM.md` and passes the frontend CI gate (issue #295). Icons
stay on `lucide-react`; do not vendor paid Central icons.

### 4. Feature flag (default **off**)

Integration is gated so the existing vanilla-JS chat/approvals plugins remain
the fallback until migration milestones (#296, #297) complete.

- **Flag:** `AIUI_BEAUTIFULUI` (build-time env / dashboard config JSON).
- **Default:** off — vanilla JS renders; the adapter is imported but not mounted.
- **On:** React islands mount using `src/agent-ui` contracts.
- **Fallback:** if a vendored component fails to load, the flag is treated as
  off and the vanilla path renders. No user-facing regression when off.

### 5. Design tokens

Scope agent-UI primitives under an `.aiui-agent-ui { … }` CSS layer (or extend
the existing shadcn presets in `themes.py`) so vendored component tokens cannot
collide with the global dashboard theme.

### 6. Deprecation / upstream abandonment

Vendored code stays MIT-licensed in-tree. Because consumers depend only on the
`contracts.ts` view models, a future first-party implementation can satisfy the
same contracts and replace the vendored components with no call-site churn.

## Consequences

- One place (`src/agent-ui/`) owns the upstream coupling.
- Adapters are testable without a browser or the transport layer.
- The default-off flag keeps the migration reversible at every step.

# BeautifulUI Upgrade Playbook

Source: https://ui.praison.ai/docs/frontend/beautifului

# BeautifulUI Upgrade Playbook

How PraisonAIUI vendors [BeautifulUI](https://www.beautifului.dev/) React primitives so
upgrades are **repeatable** and licence obligations are **explicit**.

!!! info "Related planning"
    Epic [#292](https://github.com/MervinPraison/PraisonAIUI/issues/292) (integration
    strategy) and the adapter/pin policy in
    [#294](https://github.com/MervinPraison/PraisonAIUI/issues/294).

## 1. What BeautifulUI is

BeautifulUI (MIT, © Shane Levine / Turbo) is a library of React primitives aimed at
**AI-native interfaces** — thinking traces, streaming answers with inline sources,
human-in-the-loop approval cards, tool chips, task rows, context chunks, and a reference
chat harness.

**It is a shadcn registry + copy-paste library — not an npm package.** There is no
published `beautiful-ui` package. You install components by resolving a registry URL, and
the source is copied into your tree (like any other shadcn/ui primitive).

- Website & registry: <https://www.beautifului.dev/>
- Upstream source: <https://github.com/slev12397/beautiful-ui>

Upstream stack (Next.js 15 · React 19 · Tailwind CSS v4 · TypeScript) is closely aligned
with PraisonAIUI's `src/frontend` (Vite · React 19 · Tailwind v4 · shadcn/Radix), which is
why copy-paste vendoring works without a framework shim.

## 2. One-time foundation setup

PraisonAIUI already carries the shadcn/ui foundation that BeautifulUI primitives depend on:

- **shadcn config** — `src/frontend/components.json` (`style: new-york`,
  `baseColor: neutral`, `iconLibrary: lucide`, `cssVariables: true`). Its `registries`
  map is where pinned BeautifulUI registry URLs are added (see §3).
- **Theme tokens** — `src/praisonaiui/themes.py` generates the shadcn CSS variables
  (`--background`, `--foreground`, `--primary`, `--radius`, …) at build time for all 22
  official presets, offline. BeautifulUI's foundation CSS (upstream `app/globals.css`)
  must only contribute **new** tokens/utilities; it must **not** redefine variables that
  `themes.py` already owns, or theme switching and dark mode break.

**Rule:** when merging upstream `app/globals.css`, diff it against the variables emitted by
`themes.py` and keep only the additive slices (new keyframes, component-scoped utilities).
Record what was merged in the pin doc (§3).

## 3. Adding or updating a primitive

1. **Install with a pinned registry URL** from `src/frontend/`:
   ```bash
   npx shadcn add https://www.beautifului.dev/r/<component>.json
   ```
   The registry resolves dependencies and CSS slices. Commit the resulting
   `package-lock.json` change in the same PR.
2. **Re-export through the adapter** — add the component to
   `src/frontend/src/components/index.ts` (`@praisonaiui/react`). Consumers never import
   the raw vendored path (see §4).
3. **Update the pin record** — create/update `docs/frontend/BEAUTIFULUI_UPSTREAM.md` with:
   the upstream **git SHA**, the **date**, the **registry base URL**, and the **component
   list** vendored so far. This file is the single source of truth for "what version are
   we on". (It is created the first time a real primitive is vendored — do not add it
   empty.)
4. **Rebuild & sync the bundle** — the committed frontend bundle must be regenerated:
   ```bash
   cd src/frontend && npm run build
   # then sync dist/{index.html,assets/,icon.svg} → src/praisonaiui/templates/frontend/
   ```
   (See `AGENTS.md` → "Frontend Build".)
5. **Run frontend CI** — `.github/workflows/ci.yml` (ruff + pytest) must pass, plus the
   frontend build step.

## 4. Adapter boundary

Consumers import from **`@praisonaiui/react` only** — never from raw vendored paths such as
`@/components/ui/...` or any upstream module.

```tsx
// ✅ stable PraisonAIUI contract
import { Button, ThemeToggle } from '@praisonaiui/react'

// ❌ leaks upstream/shadcn paths across the codebase
import { Button } from '@/components/ui/button'
```

This keeps the upstream surface behind one file (`components/index.ts`), so a BeautifulUI
bump changes vendored source but not consumer imports.

## 5. Rollback

- BeautifulUI-backed views mount behind a **feature flag**; the **vanilla dashboard views**
  (`src/praisonaiui/templates/frontend/plugins/*`) remain the fallback and are kept working.
- To roll back a bad bump: revert the vendoring PR (source + `BEAUTIFULUI_UPSTREAM.md` +
  rebuilt bundle move together in one commit), and disable the flag. No consumer import
  changes are needed because everything routes through the adapter (§4).

## 6. Licence

BeautifulUI is **MIT, © Shane Levine**. The full licence text is retained in
[`THIRD_PARTY_NOTICES.md`](https://github.com/MervinPraison/PraisonAIUI/blob/main/THIRD_PARTY_NOTICES.md)
at the repository root. Any PR that vendors or bumps BeautifulUI source must keep that
notice present and current.

## 7. Commercial icons — do not vendor

Do **not** use `@central-icons-react` without a licence — it is commercial. PraisonAIUI
standardises on **`lucide-react`** (`iconLibrary: lucide` in `components.json`). If an
upstream BeautifulUI primitive imports commercial icons, swap them for lucide equivalents
during vendoring.

# Deploy to GitHub Pages

Source: https://ui.praison.ai/docs/getting-started/github-pages

# Deploy to GitHub Pages

Ship your AIUI docs site to GitHub Pages with one workflow file.

## Quick Start

### 1. Project Structure

```
my-project/
├── aiui.template.yaml    # Site configuration
├── docs/                 # Your markdown content
│   ├── index.md
│   └── guide.md
├── CNAME                 # Custom domain (optional)
└── .github/
    └── workflows/
        └── deploy.yml    # GitHub Actions workflow
```

### 2. Configuration

Create `aiui.template.yaml`:

```yaml
schemaVersion: 1

site:
  title: "My Docs"
  description: "Documentation for my project"
  ui: "shadcn"
  theme:
    preset: "zinc"
    darkMode: true

content:
  docs:
    dir: "./docs"
    include:
      - "**/*.md"

templates:
  docs:
    layout: "ThreeColumnLayout"
    slots:
      header: { ref: "header_main" }
      left: { ref: "sidebar_docs" }
      main: { type: "DocContent" }
      footer: { ref: "footer_main" }

components:
  header_main:
    type: "Header"
    props:
      logoText: "My Docs"
  footer_main:
    type: "Footer"
    props:
      text: "© 2026"
  sidebar_docs:
    type: "DocsSidebar"
    props:
      source: "docs-nav"

routes:
  - match: "/docs/**"
    template: "docs"
```

### 3. GitHub Actions Workflow

Create `.github/workflows/deploy.yml`:

```yaml
name: Deploy Docs

on:
  push:
    branches: [main]

jobs:
  deploy:
    runs-on: ubuntu-latest

    permissions:
      contents: write
      pages: write
      id-token: write

    steps:
      - uses: actions/checkout@v4

      - name: Set up Python
        uses: actions/setup-python@v5
        with:
          python-version: "3.11"

      - name: Install AIUI
        run: pip install aiui

      - name: Build
        run: |
          aiui build --output site --minify
          # Preserve custom domain (if using one)
          [ -f CNAME ] && cp CNAME site/CNAME

      - name: Deploy to GitHub Pages
        uses: peaceiris/actions-gh-pages@v4
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
          publish_dir: ./site
```

### 4. Enable GitHub Pages

1. Go to **Settings → Pages** in your GitHub repo
2. Set **Source** to `Deploy from a branch`
3. Set **Branch** to `gh-pages` / `/ (root)`
4. Push to `main` — your site deploys automatically

## Custom Domain

To use a custom domain (e.g., `docs.example.com`):

1. Create a `CNAME` file in your repo root:
   ```
   docs.example.com
   ```
2. Configure DNS — add a CNAME record pointing to `<username>.github.io`
3. The workflow above automatically copies `CNAME` into the build output

## Migrating from MkDocs

Already using MkDocs? The migration is simple:

| MkDocs | AIUI |
|--------|------|
| `mkdocs.yml` | `aiui.template.yaml` |
| `mkdocs build` → `./site/` | `aiui build --output site` → `./site/` |
| `mkdocs serve` | `aiui serve` |
| `pip install mkdocs-material` | `pip install aiui` |

Your existing `docs/` folder works as-is — just swap the config and build command.

### Migration Steps

1. Create `aiui.template.yaml` (see example above)
2. Replace `mkdocs build` with `aiui build --output site --minify` in your CI workflow
3. Remove `mkdocs.yml` (optional — keep for reference)
4. Push to `main`

## Local Preview

Preview your site before deploying:

```bash
# Build and serve locally
aiui build
aiui serve

# Or use dev mode with hot reload
aiui dev
```

## Build Output

`aiui build --output site` produces:

```
site/
├── index.html           # SPA entry point
├── assets/              # JS + CSS bundles
│   ├── index.js
│   └── index.css
├── ui-config.json       # Site configuration manifest
├── docs-nav.json        # Navigation tree
├── route-manifest.json  # Route definitions
└── docs/                # Markdown content (copied)
    ├── index.md
    └── ...
```

Everything is static — no server required. GitHub Pages serves it directly.

# Quick Start

Get a working AI dashboard in under 60 seconds.

## Prerequisites

- Python 3.10+
- An OpenAI API key (or compatible provider)

```bash
export OPENAI_API_KEY="sk-..."
```

## Install

```bash
pip install aiui
```

## Option 1: Dashboard Mode (recommended)

Create an `app.py`:

```python
import praisonaiui as aiui

aiui.set_style("dashboard")
aiui.set_pages(["chat", "agents", "memory", "sessions", "config"])
aiui.set_branding(title="PraisonAI", logo="🦞")

aiui.register_agent({
    "agent_id": "assistant",
    "name": "Assistant",
    "description": "General purpose AI assistant",
    "instructions": "You are a helpful assistant. Be concise.",
    "model": "gpt-4o-mini",
    "icon": "🤖",
})

@aiui.reply
async def on_reply(message):
    """Handle incoming chat messages."""
    # The registered agent handles the reply automatically
    pass
```

Run:

```bash
aiui run app.py
```

Open **http://localhost:8000** — your dashboard is live with chat, agent management, memory, sessions, and config pages.

## Option 2: YAML Chat Mode

Create a `chat.yaml`:

```yaml
name: My Assistant
instructions: You are a helpful assistant.
model: gpt-4o-mini
welcome: "Hi! How can I help you today?"
starters:
  - label: "What can you do?"
    message: "Tell me about your capabilities"
  - label: "Help me write"
    message: "Help me draft an email"
tools:
  - web_search
features: true
```

Run:

```bash
aiui run chat.yaml
```

## Option 3: Documentation Mode

Generate a static docs site from Markdown files:

```bash
aiui init --template docs
# Edit docs/*.md files
aiui build
aiui serve
```

## Next Steps

- **[CLI Reference](cli.md)** — Full command reference with all 22 command groups
- **[Python API](../api/python.md)** — SDK function reference
- **[Dashboard Features](../features/dashboard.md)** — All 24 dashboard pages
- **[Configuration](../concepts/configuration.md)** — YAML configuration guide

## Diagnostics

If something isn't working:

```bash
aiui doctor               # Check server health
aiui health-check --detailed  # Detailed health check (alias: aiui health)
aiui test all              # Run all integration tests
```

# Application Design Protocol (ADP) — Research Report

Source: https://ui.praison.ai/docs/protocols/application-design-protocol-report

# Application Design Protocol (ADP) — Research Report

**Version:** 1.0 (draft)  
**Date:** August 2026  
**Scope:** UI, layout, navigation, theming — declarative application design from text manifests  
**Status:** Research and recommendation; not yet a published standard

---

## 1. Executive summary

There is no single existing standard for **designing full application UI from a declarative text file**. Instead, the problem is addressed in fragments:

- **Docs-site generators** (Mintlify, PraisonAIUI, Hugo) declare navigation and layout in config files.
- **Form libraries** (JSON Forms, RJSF) declare layout trees from JSON Schema.
- **Agent UI protocols** (A2UI, AG-UI) declare streaming component surfaces for LLM-generated UI.
- **Catalog standards** (OpenUI, Backstage) declare component metadata without runtime layout.
- **Design token standards** (DTCG 2025.10) declare theming without structure.

**Recommendation:** Define an **Application Design Protocol (ADP)** that synthesises proven patterns from 46 surveyed standards into a UI-only manifest format.

PraisonAIUI already implements approximately 60% of this model. ADP formalises, extends, and publishes what exists today.

---

## 2. Problem statement

### 2.1 What we need

A protocol that lets a developer (or LLM) describe an application's visual design — pages, navigation, components, themes, routes — in **one or more text files**, without writing application code.

### 2.2 What exists today (fragmented)

| Need | Who solves it | Gap |
|------|---------------|-----|
| Docs site from config | Mintlify, PraisonAIUI, Docusaurus | No shared spec; Mintlify uses JSON, others use YAML or JS |
| Component catalog | OpenUI, A2UI | No layout or routing |
| Layout trees | JSON Forms uiSchema | Forms only, not app shells |
| Theming | DTCG, Material 3 | Tokens only, no pages |
| Agent-generated UI | A2UI | Runtime streaming, not human-authored static sites |
| Software metadata | Backstage | Catalog entities, not UI composition |

### 2.3 Design goals for ADP

1. **Human-readable** — editable without IDE plugins
2. **LLM-safe** — structural schema rejects unknown fields
3. **Portable** — same manifest renders on any ADP-compliant runtime
4. **Validatable** — fail fast at build time, not in the browser
5. **Extensible** — plugins add catalog entries, not inline code
6. **Accessible** — ARIA hints required in component catalog

---

## 3. Standards landscape — 46 protocols in 10 categories

Each entry describes **how UI/layout/navigation is declared** — the primary comparison dimension.

### Category A: Web platform baseline (5)

| Standard | Format | How UI/layout/navigation is declared | Schema | Versioning |

### Category J: Application packaging (2)

| Standard | Format | Application declaration |
|----------|--------|------------------------|
| **OAM** | YAML | `Application` with `components[]`, `traits[]` |
| **CNAB** | bundle.json | Parameters, credentials, actions |

---

## 4. How they do it — mechanism comparison matrix

| Mechanism | Standards | How it works | ADP |
|-----------|-----------|--------------|-----|
| **Envelope document** | K8s, Backstage, OAM, AWP | `apiVersion` + `kind` + `metadata` + `spec` | Adopt |
| **Component registry + ref** | PraisonAIUI, OpenUI | Named map; templates use `ref:` | Adopt |
| **Layout + slots** | PraisonAIUI, JSON Forms | Layout type + named regions | Adopt (unified) |
| **Route → template** | PraisonAIUI, Flutter | URL glob → template | Adopt |
| **Navigation tree** | Mintlify, Storybook | Hierarchical groups → pages | Adopt |
| **Design token file** | DTCG, Material 3 | Token JSON with aliases | Adopt |
| **Catalog allowlist** | A2UI, OpenUI | Closed component vocabulary | Adopt |
| **Schema + uiSchema split** | JSON Forms, RJSF | Data vs presentation | Partial |
| **Streaming surfaces** | A2UI, AG-UI | Incremental JSON updates | Future |
| **Layered spec** | AWP, Helm | Separate files merged at compile | Adopt |
| **File includes** | Backstage, Mintlify | `$yaml:` / `$ref` external files | Adopt |
| **Structural pruning** | K8s CRD | Reject unknown fields | Adopt |
| **Validation rules R1–Rn** | AWP | Cross-ref beyond JSON Schema | Adopt |
| **JS executable config** | Docusaurus, Gatsby | Code config | Reject |
| **Visual canvas** | Figma, Webflow | Proprietary designer | Reject |
| **Code-only UI** | Compose, SwiftUI | No wire format | Out of scope |

---

## 5. Side-by-side: four closest analogues

| Dimension | PraisonAIUI | Mintlify | A2UI | Backstage |
|-----------|-------------|----------|------|-----------|
| **Authoring format** | YAML | JSON | JSON (stream) | YAML |
| **Envelope** | `schemaVersion` only | Flat JSON | Message `version` | `apiVersion/kind/metadata/spec` |
| **Navigation** | `navigation.tabs[]` + filesystem | `navigation.groups[]` | N/A | N/A (metadata catalog) |
| **Components** | `components{id: type, props}` | N/A | Catalog + adjacency list | Entity kinds |
| **Layout** | `templates{layout, slots, zones}` | Theme only | Surfaces | N/A |
| **Routes** | `routes{match, template}` | Page paths in nav | N/A | N/A |
| **Schema published** | Pydantic only | `$schema` URL | JSON Schema catalog | JSON Schema per kind |
| **Runtime** | React SPA | Hosted platform | Any renderer | Catalog API |
| **Primary use** | Docs sites | Docs sites | Agent-generated UI | Software inventory |

**Synthesis:** ADP combines PraisonAIUI's composition model, Mintlify's schema publishing, A2UI's catalog allowlist, and Backstage's envelope and file includes.

---

## 6. YAML vs alternatives — structured debate

### 6.1 The assumption

YAML is the best authoring format for application design manifests.

### 6.2 Counter-evidence

**Mintlify** — the closest commercial docs-site analogue — uses **JSON** (`docs.json`) with a published `$schema` URL for IDE autocomplete. This works well for flat-to-moderately-nested config but becomes verbose for deep layout trees.

**A2UI** uses **JSON** as both authoring and wire format because LLMs emit structured JSON reliably and ambiguity is unacceptable at runtime.

**Docusaurus and Gatsby** use **JavaScript/TypeScript** config for programmatic power — but this sacrifices portability and LLM generation safety.

### 6.3 Format comparison

| Format | Strengths | Weaknesses for ADP |
|--------|-----------|-------------------|
| **YAML** | Comments; readable nesting; LLM-friendly; PraisonAIUI continuity | Ambiguous typing; merge key footguns; no native DRY |
| **JSON** | Unambiguous; `$schema` IDE support; Mintlify-proven | No comments; verbose for layout trees |
| **TOML** | Clear flat tables (Hugo) | Poor for nested templates/zones |
| **CUE / Jsonnet / Pkl** | Typed composition without templating | Learning curve; not LLM-default |
| **HCL** | Modules, expressions | Ecosystem-bound; overkill for UI-only |
| **JS/TS** | Full programmatic power | Not portable; not LLM-safe |

### 6.4 Recommendation

```
Author (human/LLM) → YAML (default) or JSON (alternate)
        ↓
   ADP compiler/validator (JSON Schema 2020-12)
        ↓
   Normalised JSON manifest (runtime)
        ↓
   UI renderer (catalog-constrained)
```

- **Primary authoring:** YAML — best for nested `templates` / `zones` trees
- **Alternate authoring:** JSON — for teams preferring Mintlify-style `$schema` tooling
- **Never at runtime:** YAML — always compile to JSON before serve
- **Composition:** `$yaml:` file includes (Backstage), not Helm Go templates
- **Power users:** Optional CUE/Jsonnet compiles to YAML before validation

**Verdict:** YAML remains the recommended default, but ADP MUST accept JSON as an equivalent authoring format with identical semantics.

---

## 7. ADP design principles

1. **Declarative, not executable** — manifests describe intent; runtimes render; no inline code or templating logic in core spec.
2. **Schema-first** — JSON Schema 2020-12 is canonical; YAML is authoring convenience.
3. **Structural strictness** — unknown fields rejected in strict mode (K8s CRD pattern).
4. **Catalog allowlist** — component `type` must exist in published catalog (A2UI pattern).
5. **Envelope consistency** — every document uses `apiVersion`, `kind`, `metadata`, `spec`.
6. **Separation of concerns** — theme, navigation, components, templates, routes are distinct spec sections.
7. **Compile, don't interpret** — YAML → validated JSON manifest → static assets at build time.
8. **Accessibility by default** — catalog entries include ARIA role hints (WAI-ARIA pattern).
9. **Versioned protocol** — `schemaVersion` integer + `apiVersion` string; breaking changes bump version.
10. **Extension namespace** — `x-adp-*` prefix reserved; plugins register catalog layers.
11. **File composition** — `$yaml:` includes for modular configs (Backstage pattern).
12. **Route-driven rendering** — URL resolution selects template; no hardcoded layout in renderer.

---

## 8. Proposed ADP document model

```yaml
schemaVersion: 1
apiVersion: adp.io/v1alpha1
kind: Application

metadata:
  name: my-docs-site
  version: "1.0.0"
  labels: {}

spec:
  site:
    title: "My Site"
    description: "..."
  theme:
    preset: zinc          # or DTCG token ref
    radius: md
    darkMode: true
  navigation:
    mode: auto            # auto | manual
    tabs: [...]
  components:
    header_main:
      type: Header
      props: { logoText: "..." }
  templates:
    docs:
      layout: ThreeColumnLayout
      slots:
        header: { ref: header_main }
        main: { type: DocContent }
  routes:
    - match: "/docs/**"
      template: docs
  content:
    docs:
      dir: "./docs"
```

### Data flow

```
application.yaml → Parse → JSON Schema validate → Cross-ref rules (R1–R30)
        → Compile → ui-config.json + route-manifest.json + docs-nav.json
        → React / static renderer
```

---

## 9. PraisonAIUI alignment and gaps

### Already aligned

| PraisonAIUI today | ADP equivalent |
|-------------------|----------------|
| `schemaVersion: 1` | `schemaVersion` + `apiVersion` |
| `components` + `ref:` | `spec.components` + slot refs |
| `templates.layout` + `slots` | `spec.templates` |
| `routes` | `spec.routes` |
| `site.theme` | `spec.theme` |
| Compiler → JSON manifests | ADP compile pipeline |
| Pydantic validation | JSON Schema + cross-ref rules |

### Gaps to close

| Gap | ADP fix |
|-----|---------|
| No published JSON Schema | Publish `application.schema.json` |
| `navigation.tabs` compiled but not rendered | Mandate runtime consumption in spec |
| `route-manifest.json` not used for routing | Mandate route-driven template resolution |
| Dual slots + zones models | Unified: zones = ordered slot arrays |
| Closed hardcoded component types | Published `component-catalog.schema.json` |
| No envelope (`kind`, `metadata`) | Add Backstage-style envelope |

---

## 10. Migration path

Existing `aiui.template.yaml` files remain valid. Migration steps:

1. Add `apiVersion: adp.io/v1alpha1` and `kind: Application` (optional during transition).
2. Wrap top-level keys under `spec:` (compiler accepts both shapes during v1alpha1).
3. Rename `site` fields unchanged; map `navigation`, `templates`, `routes` as-is.
4. Publish catalog; register custom component types via plugin schema layers.

See [adp/aiui-mapping.md](./adp/aiui-mapping.md) for field-by-field mapping.

---

## 11. Open questions

1. **Should ADP standardise layout type names** (`ThreeColumnLayout`) or allow runtime-defined layouts?
2. **Should navigation support both filesystem-auto and manual tabs** in one spec, or require a mode switch?
3. **Should agent-driven surfaces (A2UI) be a separate `kind: Surface`** or embedded in Application?
4. **Should theme reference DTCG token files directly** or use simplified preset shorthand?

## 13. Conclusion

ADP is feasible and largely prefigured by PraisonAIUI's existing architecture. The research across 46 standards yields a clear synthesis:

- **Envelope** from Backstage/K8s
- **Composition** from PraisonAIUI (components → templates → routes)
- **Catalog** from A2UI/OpenUI
- **Theming** from DTCG
- **Validation** from AWP (structural schema + R-rules)
- **Authoring** in YAML (default) with JSON alternate (Mintlify pattern)

**Status:** Research draft — see [adp/implementation-status.md](./adp/implementation-status.md) for implementation gaps.

The draft spec, JSON Schema files, and example manifests are published alongside this report in [`docs/protocols/adp/`](./adp/).

# PraisonAIUI → ADP Field Mapping

Source: https://ui.praison.ai/docs/protocols/adp/aiui-mapping

# PraisonAIUI → ADP Field Mapping

Field-by-field mapping from current `aiui.template.yaml` (`Config` model in `src/praisonaiui/schema/models.py`) to ADP `Application` spec.

**Compatibility:** Flat `aiui.template.yaml` files work with the PraisonAIUI compiler today. ADP envelope format is **planned** — see [implementation-status.md](./implementation-status.md).

---

## Envelope (new in ADP)

| ADP field | PraisonAIUI today | Status | Change |

| `kind: Application` | Not present | Planned | Add when envelope parser lands |
| `metadata.name` | Not present | Planned | Derive from `site.title` slug |
| `metadata.version` | Not present | Planned | Recommend SemVer |

## Top-level → spec wrapper

| `logo:` (top-level) | Future ADP field | Implemented | Top-level on `Config`, not under `site` |
| `style:`, `chat:`, `auth:`, `dashboard:` | Not in ADP v1alpha1 | N/A | Separate kinds in future |

## Navigation fields

| Field | PraisonAIUI | ADP | Status | Notes |
|-------|-------------|-----|--------|-------|
| `navigation.tabs[]` | Mintlify-style tabs | `spec.navigation.tabs` | Partial | Compiled, not rendered |
| `content.docs.nav.mode` | `NavConfig.mode` | Same | Gap | Defined but unused by compiler |
| Top-level `navigation.mode` | Not present | Removed from ADP | N/A | Use `content.docs.nav.mode` instead |

## Migration example

### Today (PraisonAIUI)

```yaml
schemaVersion: 1

site:
  title: "My Docs"
  theme:
    preset: zinc

templates:
  docs:
    layout: TwoColumnLayout
    slots:
      main: { type: DocContent }

routes:
  - match: "/docs/**"
    template: docs
```

### Target (ADP)

```yaml
schemaVersion: 1
apiVersion: adp.io/v1alpha1
kind: Application

metadata:
  name: my-docs
  version: "1.0.0"

spec:
  site:
    title: "My Docs"
  theme:
    preset: zinc
  templates:
    docs:
      layout: TwoColumnLayout
      slots:
        main: { type: DocContent }
  routes:
    - match: "/docs/**"
      template: docs
  content:
    docs:
      dir: "./docs"
```

## Breaking vs compatible changes

| Change | Breaking? | Mitigation |
|--------|-----------|------------|
| Add envelope fields | No | Envelope parser normalises to flat `Config` |
| Catalog validation | Soft break | Warn first, error in strict mode |
| Route runtime resolution | No (fix) | Frontend change |
| R13 slots/zones exclusivity | Soft break | Warn on violation |
| Remove chat/dashboard from ADP | No | Separate kinds in future |

# ADP Implementation Status

Honest status of ADP v1alpha1 features against the PraisonAIUI reference implementation.

**Last updated:** August 2026

| Feature | Spec reference | Status | Notes |
|---------|----------------|--------|-------|
| JSON Schema validation in CLI | spec §6 | Planned | Schemas published; no `aiui validate --adp` yet |
| ADP envelope parsing (`apiVersion/kind/spec`) | spec §3 | Planned | Flat `aiui.template.yaml` works today |
| Component catalog validation (R6–R7) | spec §5 | Planned | Catalog split to `catalogs/default.catalog.json` |
| `$yaml:` / `$json:` file includes | spec §7 | Planned | Not implemented in compiler |
| Strict mode unknown-field rejection (R4) | validation-rules R4 | Planned | Pydantic allows extra fields on some models |
| Route-driven template resolution (R28) | validation-rules R28 | Gap | Frontend hardcodes `templates.docs` |
| Sidebar nav mode (R29) | validation-rules R29 | Gap | Filesystem-only sidebar today |
| Catalog ARIA roles at render (R30) | validation-rules R30 | Gap | No catalog-driven a11y in renderer |
| `navigation.tabs` rendering | spec §4.3 | Gap | Compiled to manifest but not consumed by React |
| DTCG token file validation (R26) | validation-rules R26 | Planned | Preset shorthand works via Tailwind |
| Published `$schema` URLs | README | Partial | Local schemas only; `https://adp.io/` is placeholder |

## What works today

- Flat `aiui.template.yaml` → Pydantic `Config` → compiler → JSON manifests → React SPA
- Components, templates, routes, theme presets, content scanning
- ADP example manifests validate against `application.schema.json` (standalone)
- Unit tests in `tests/unit/test_adp_schemas.py`

## Migration path

1. Add envelope normalisation layer before `Config.model_validate`
2. Wire `route-manifest.json` into frontend routing (R28)
3. Honour `navigation.tabs` and `content.docs.nav.mode` (R29)
4. Add `aiui validate --schema adp` using published JSON Schema
5. Apply catalog ARIA hints at render time (R30)

See [aiui-mapping.md](./aiui-mapping.md) for field-level compatibility.

# Application Design Protocol (ADP) — Normative Specification

Source: https://ui.praison.ai/docs/protocols/adp/spec

# Application Design Protocol (ADP) — Normative Specification

**Version:** v1alpha1 (draft)  
**Status:** Draft — not yet normative  
**Date:** August 2026

This document uses [RFC 2119](https://datatracker.ietf.org/doc/html/rfc2119) keywords: MUST, MUST NOT, SHOULD, MAY.

---

## 1. Scope

ADP defines a declarative format for describing **application UI design**: site metadata, theming, navigation, reusable components, page templates, and URL routing. It does NOT define:

- Server-side APIs or data models
- Agent orchestration or workflow graphs
- Infrastructure or deployment configuration
- Executable code or templating logic in manifests

Implementations MUST treat ADP manifests as **data**, not code.

---

## 2. Terminology

| Term | Definition |
|------|------------|
| **Manifest** | A YAML or JSON document conforming to this spec |
| **Application** | The root `kind: Application` manifest describing a complete UI |
| **Component** | A named, reusable UI block with a `type` and `props` |
| **Template** | A layout definition assigning components to slots or zones |
| **Slot** | A named region within a layout (e.g. `header`, `main`) |
| **Zone** | An ordered list of widgets in a slot (WordPress-style) |
| **Route** | A URL pattern mapping to a template |
| **Catalog** | Published JSON Schema defining allowed component types |
| **Compiler** | Tool that validates and emits runtime JSON manifests |
| **Renderer** | Runtime that consumes compiled manifests and renders UI |

---

## 3. Document envelope

Every ADP manifest MUST include:

```yaml
schemaVersion: 1          # Integer; ADP envelope version
apiVersion: adp.io/v1alpha1
kind: Application         # Application | Theme | ComponentCatalog (future)

metadata:
  name: string            # Required; unique identifier
  version: string         # SHOULD use SemVer
  labels: object          # MAY contain key-value pairs
  annotations: object     # MAY contain tooling metadata

spec: object              # Required; kind-specific payload
```

### 3.1 Versioning policy

- `schemaVersion` — integer bumped on breaking envelope changes
- `apiVersion` — string group/version (e.g. `adp.io/v1alpha1`, `adp.io/v1`)
- `metadata.version` — application SemVer (independent of protocol version)
- Breaking changes MUST increment `apiVersion` (e.g. v1alpha1 → v1)
- Deprecated fields MUST include `deprecated: true` and SHOULD include `x-sunset` date

### 3.2 Authoring formats

Manifests MAY be authored as YAML (`.application.yaml`) or JSON (`.application.json`). Semantics MUST be identical. Runtimes MUST NOT consume YAML directly; compilers MUST normalise to JSON before validation.

---

## 4. Application spec

An `Application` spec MUST contain at minimum:

| Field | Required | Description |
|-------|----------|-------------|
| `site.title` | YES | Application display name |
| `templates` | YES | At least one template |
| `routes` | YES | At least one route |

All other fields are OPTIONAL.

### 4.1 Site (`spec.site`)

```yaml
site:
  title: string           # Required
  description: string     # Optional
  ui: shadcn              # UI framework hint; default shadcn
  routeBaseDocs: /docs    # Base path for documentation routes
```

### 4.2 Theme (`spec.theme`)

Theme MAY use preset shorthand or reference a DTCG token file:

```yaml
theme:
  preset: zinc            # Tailwind-style preset name
  radius: md              # none | sm | md | lg | xl
  darkMode: true
  # OR
  tokens: $yaml: ./theme.tokens.json   # DTCG 2025.10 file
```

### 4.3 Navigation

ADP separates **top tab bar** from **sidebar source**:

```yaml
navigation:
  tabs:                   # Top tab bar (Mintlify-style)
    - tab: Documentation
      groups:
        - group: Getting Started
          pages: [index, getting-started/installation]

content:
  docs:
    dir: ./docs
    nav:
      mode: auto           # auto | manual — sidebar source
      sort: filesystem
      collapsible: true
      maxDepth: 4
```

- **`navigation.tabs`** — top-level tab bar with grouped pages
- **`content.docs.nav.mode: auto`** — sidebar generated from filesystem scan
- **`content.docs.nav.mode: manual`** — sidebar driven by `navigation.tabs` groups
- Renderers MUST honour `content.docs.nav.mode` when building sidebar (R29)

### 4.4 Components (`spec.components`)

```yaml
components:
  header_main:
    type: Header          # MUST exist in component catalog
    props:
      logoText: PraisonAIUI
```

Rules:
- Component IDs MUST be unique within the manifest
- `type` MUST match an entry in the published component catalog
- `props` MUST validate against the catalog JSON Schema for that type

### 4.5 Templates (`spec.templates`)

```yaml
templates:
  docs:
    layout: ThreeColumnLayout
    slots:
      header: { ref: header_main }
      left: { ref: sidebar_docs }
      main: { type: DocContent }
      right: null           # Explicitly hide slot

  landing:
    layout: FlexibleLayout
    zones:
      hero:
        - type: HeroBanner
          props: { title: "Welcome" }
```

Rules:
- `layout` MUST be a known layout type in the catalog
- Each slot value MUST be `{ ref: id }`, `{ type: ComponentType }`, or `null`
- Zones MUST use zone names valid for `FlexibleLayout`
- A template MUST declare either `slots` or `zones`, not both (R13)

### 4.6 Routes (`spec.routes`)

```yaml
routes:
  - match: /docs/changelog
    template: changelog
    slots:                  # Optional per-route slot overrides
      right: null
  - match: /docs/**
    template: docs
```

Rules:
- Routes MUST be ordered most-specific-first
- `match` MUST be a glob pattern
- `template` MUST reference a key in `spec.templates`
- Renderers MUST resolve routes at runtime using compiled `route-manifest.json`

### 4.7 Content (`spec.content`)

```yaml
content:
  docs:
    dir: ./docs
    include: ["**/*.md", "**/*.mdx"]
    exclude: []
    nav:
      mode: auto
      sort: filesystem
      collapsible: true
      maxDepth: 4
```

---

## 5. Component catalog

Implementations MUST publish a `component-catalog.schema.json` (meta-schema) and a catalog instance such as [`catalogs/default.catalog.json`](./catalogs/default.catalog.json):

```json
{
  "name": "adp-default-catalog",
  "version": "1.0.0",
  "components": {
    "Header": {
      "description": "Site header with logo and navigation",
      "props": {
        "type": "object",
        "properties": { "logoText": { "type": "string" } },
        "required": ["logoText"],
        "additionalProperties": false
      },
      "aria": { "role": "banner" },
      "slots": ["header"]
    }
  },
  "layouts": {
    "ThreeColumnLayout": {
      "description": "Header + sidebar + main + TOC + footer",
      "slots": ["header", "left", "main", "right", "footer"]
    }
  }
}
```

Custom component types MUST be registered via plugin schema layers. Unknown types MUST cause validation failure in strict mode.

---

## 6. Compilation pipeline

A conforming compiler MUST:

1. Parse YAML or JSON manifest
2. Normalise to JSON
3. Validate against `application.schema.json` (JSON Schema 2020-12)
4. Validate cross-reference rules (see [validation-rules.md](./validation-rules.md))
5. Validate component props against catalog schema
6. Emit runtime manifests:
   - `ui-config.json` — site, components, templates, theme, navigation
   - `route-manifest.json` — ordered routes with template refs
   - `docs-nav.json` — filesystem-derived navigation (if mode auto)

---

## 7. File composition

Manifests MAY include external files using Backstage-style placeholders:

```yaml
theme:
  $yaml: ./theme.yaml

navigation:
  $yaml: ./navigation.yaml
```

Rules:
- Paths MUST be relative to the containing manifest
- Path traversal (`../../`) MUST be rejected
- Supported placeholders: `$yaml:`, `$json:`, `$text:`

---

## 8. Extensions

Vendor extensions MUST use the `x-adp-` prefix:

```yaml
spec:
  site:
    x-adp-customAnalytics: true
```

Implementations MUST preserve unknown `x-adp-*` fields. Non-prefixed unknown fields MUST be rejected in strict mode.

---

## 9. Conformance

An implementation is **ADP-conformant** if and only if it:

1. Accepts manifests with `apiVersion: adp.io/v1alpha1` and `kind: Application`
2. Validates all MUST-level requirements in this spec and validation-rules.md
3. Rejects manifests with unknown fields in strict mode
4. Emits runtime JSON manifests from valid Application specs
5. Resolves routes to templates at render time

# ADP Validation Rules

Source: https://ui.praison.ai/docs/protocols/adp/validation-rules

# ADP Validation Rules

Cross-reference validation rules for Application Design Protocol manifests. These constraints cannot be expressed in JSON Schema alone and MUST be enforced by conforming compilers.

Rules use RFC 2119 keywords: MUST, MUST NOT, SHOULD, MAY.

Inspired by AWP validation rules R1–R32 pattern.

---

## Envelope rules

| Rule | Level | Description |
|------|-------|-------------|
| **R1** | MUST | `schemaVersion` MUST equal `1` for `apiVersion: adp.io/v1alpha1` |
| **R2** | MUST | `kind` MUST be `Application` for root manifests |
| **R3** | MUST | `metadata.name` MUST be unique within a deployment scope |
| **R4** | MUST NOT | Unknown top-level fields outside `x-adp-*` namespace in strict mode |

## Component rules

| Rule | Level | Description |
|------|-------|-------------|
| **R5** | MUST | Every `spec.components` entry MUST have a unique ID |
| **R6** | MUST | Every component `type` MUST exist in the published component catalog |
| **R7** | MUST | Component `props` MUST validate against catalog JSON Schema for that type |
| **R8** | MUST NOT | A component ID be referenced by `ref:` unless it exists in `spec.components` |
| **R9** | SHOULD | Unused components (defined but never referenced) SHOULD emit a warning |

## Template rules

| Rule | Level | Description |
|------|-------|-------------|
| **R10** | MUST | Every `spec.templates` entry MUST declare a valid `layout` from the catalog |
| **R11** | MUST | Slot names in `templates.*.slots` MUST be valid for the declared layout |
| **R12** | MUST | Zone names in `templates.*.zones` MUST be valid for `FlexibleLayout` |
| **R13** | MUST | Each template MUST declare either `slots` or `zones`, not both |
| **R14** | MUST | Inline slot `{ type: X }` types MUST exist in the component catalog |
| **R15** | MUST | Slot `{ ref: id }` MUST resolve to a component in `spec.components` |

## Route rules

| Rule | Level | Description |
|------|-------|-------------|
| **R16** | MUST | Every route `template` MUST reference a key in `spec.templates` |
| **R17** | MUST | Routes MUST be ordered most-specific-first (longer/more precise patterns before wildcards) |
| **R18** | MUST | Route slot overrides MUST use valid slot names for the target template's layout |
| **R19** | SHOULD | At least one route SHOULD match the site root or docs base path |

## Content and navigation rules

| Rule | Level | Description |
|------|-------|-------------|
| **R20** | MUST | If `content.docs.dir` is declared, the directory MUST exist at compile time |
| **R21** | MUST | If `content.docs.nav.mode` is `manual`, `navigation.tabs` MUST be non-empty |
| **R22** | SHOULD | If `content.docs.nav.mode` is `auto`, a content source MUST be declared |

Navigation model:

- **`navigation.tabs`** — top tab bar (Mintlify-style)
- **`content.docs.nav.mode`** — sidebar source: `auto` (filesystem scan) or `manual` (use `navigation.tabs` groups)

## File include rules

| Rule | Level | Description |
|------|-------|-------------|
| **R23** | MUST NOT | `$yaml:`, `$json:`, or `$text:` paths traverse outside the project root |
| **R24** | MUST | Included files MUST parse as valid YAML/JSON/text respectively |
| **R25** | MUST NOT | Circular file includes (A includes B includes A) |

## Theme rules

| Rule | Level | Description |
|------|-------|-------------|
| **R26** | MUST | If `theme.tokens` is declared, the referenced file MUST exist and validate against DTCG 2025.10 |
| **R27** | MUST NOT | Both `theme.preset` and `theme.tokens` be declared simultaneously |

## Renderer conformance (target — not yet implemented in PraisonAIUI)

These rules define the target behaviour for ADP-conformant renderers. See [implementation-status.md](./implementation-status.md).

| Rule | Level | Description |
|------|-------|-------------|

| **R29** | MUST | Renderers MUST honour `content.docs.nav.mode` when building sidebar |
| **R30** | MUST | Renderers MUST apply ARIA roles from catalog for each rendered component |

---

## Validation pipeline order

```
1. Parse YAML/JSON
2. Resolve $yaml/$json/$text includes (R23–R25)
3. JSON Schema validate (application.schema.json)
4. Cross-ref rules R1–R27
5. Component props validate against catalog (R6–R7)
6. Emit runtime manifests
7. Runtime conformance R28–R30 (renderer responsibility)
```

## Error format

Validation failures MUST report:

```json
{
  "rule": "R8",
  "path": "spec.templates.docs.slots.header.ref",
  "message": "Component ref 'missing_header' not found in spec.components",
  "severity": "error"
}
```

Warnings (R9) use `"severity": "warning"`.

## Layout Components

### ThreeColumnLayout

Documentation layout with sidebar and TOC.

```tsx
import { ThreeColumnLayout } from 'praisonaiui/components';

<ThreeColumnLayout
  header={<Header />}
  left={<Sidebar />}
  main={<Content />}
  right={<Toc />}
  footer={<Footer />}
/>

Simple layout for landing pages.

```tsx
import { DefaultLayout } from 'praisonaiui/components';

<DefaultLayout
  header={<Header />}
  hero={<Hero />}
  main={<Content />}
  footer={<Footer />}
/>
```

## Slot Components

### Header

```tsx
import { Header } from 'praisonaiui/components';

<Header
  logoText="My Site"
  logoHref="/"
  links={[
    { label: "Docs", href: "/docs" },
    { label: "Blog", href: "/blog" }
  ]}
  cta={{ label: "Get Started", href: "/start" }}
/>
```

### Footer

```tsx
import { Footer } from 'praisonaiui/components';

## Styling Components

All components use semantic CSS classes prefixed with `aiui-`. Style them with your preferred CSS approach:

| Component | CSS Classes |
|-----------|-------------|
| Layouts | `aiui-layout`, `aiui-layout-three-column`, `aiui-layout-header`, `aiui-layout-main` |
| Header | `aiui-header`, `aiui-header-logo`, `aiui-header-nav`, `aiui-header-cta` |
| Footer | `aiui-footer`, `aiui-footer-links` |
| Sidebar | `aiui-sidebar`, `aiui-sidebar-item`, `aiui-sidebar-group` |
| Toc | `aiui-toc`, `aiui-toc-item` |
| Content | `aiui-content`, `aiui-content-body` |

```css
/* Example custom styling */
.aiui-header {
  background: linear-gradient(to right, #6366f1, #8b5cf6);
}

# Next.js Adapter

Integrate PraisonAIUI with Next.js.

## Installation

```bash
npm install praisonaiui next react react-dom
```

## Configuration

Wrap your Next.js config:

```typescript
// next.config.ts
import { withAIUI } from 'praisonaiui/next';

export default withAIUI({
  // your Next.js config options
});
```

## Page Setup

### App Router

```typescript
// app/docs/[...slug]/page.tsx
import { getDocsPageProps } from 'praisonaiui/next';
import { DocsPage } from 'praisonaiui/components';

export default async function Page({ params }) {
  const props = await getDocsPageProps(params.slug);
  return <DocsPage {...props} />;
}

export async function generateStaticParams() {
  // Generate paths from docs-nav.json
}
```

### Pages Router

```typescript
// pages/docs/[...slug].tsx
import { getDocsPageProps } from 'praisonaiui/next';
import { DocsPage } from 'praisonaiui/components';

export default function Page(props) {
  return <DocsPage {...props} />;
}

export async function getStaticProps({ params }) {
  return {
    props: await getDocsPageProps(params.slug)
  };
}

export async function getStaticPaths() {
  // Generate paths
}
```

## MDX Support

Enable MDX:

```typescript
// next.config.ts
import { withAIUI } from 'praisonaiui/next';

export default withAIUI({
  // MDX is enabled by default
});
```

---

# Runtime

Source: https://ui.praison.ai/docs/typescript/runtime

# Runtime

Core runtime utilities for the TypeScript SDK.

## createAIUI

Initialize the runtime:

```typescript
import { createAIUI } from 'praisonaiui/runtime';

const aiui = createAIUI({
  manifestPath: './aiui',  // Path to manifests
  basePath: '/docs'        // Base path for docs
});
```

## resolveTemplate

Match a route to its template configuration:

```typescript
import { resolveTemplate } from 'praisonaiui/runtime';

const template = resolveTemplate('/docs/getting-started', routeManifest);

console.log(template);
// {
//   layout: "ThreeColumnLayout",
//   slots: {
//     header: { ref: "main_header" },
//     main: { type: "DocContent" }
//   }
// }
```

## SlotRegistry

Register and retrieve slot components:

```typescript
import { SlotRegistry } from 'praisonaiui/runtime';

// Register custom component
SlotRegistry.register('Header', MyCustomHeader);

// Get component
const HeaderComponent = SlotRegistry.get('Header');

// Check if registered
if (SlotRegistry.has('Footer')) {
  // ...
}

// Get all registered
const all = SlotRegistry.getAll();
```

## Manifest Loading

```typescript
import { loadManifest } from 'praisonaiui/runtime';

const uiConfig = await loadManifest('ui-config.json');
const docsNav = await loadManifest('docs-nav.json');
const routes = await loadManifest('route-manifest.json');
```
