+## N/A (Rust Language Limitations)
+
+These Python features cannot be directly implemented in Rust due to reserved keywords or module naming conflicts. Equivalent functionality exists under different names.
+
+- ⚠️ `config` → Use `parity_config` instead
+- ⚠️ `db` → Use `parity_db` instead
+- ⚠️ `memory` (Rust reserved/module conflict)
+- ⚠️ `obs` → Use `parity_obs` instead
+- ⚠️ `tools` (Rust reserved/module conflict)

+# PraisonAI Rust SDK
+
+High-performance, agentic AI framework for Rust.
+
+## Quick Start
+
+```rust
+use praisonai::{Agent, tool, Tool};
+
+#[tool(description = "Search the web")]
+async fn search(query: String) -> String {
+    format!("Results for: {}", query)
+}
+
+#[tokio::main]
+async fn main() -> anyhow::Result<()> {
+    let agent = Agent::new()
+        .instructions("You are a helpful assistant")
+        .tool(SearchTool::new())
+        .build()?;
+    
+    let response = agent.chat("Hello!").await?;
+    println!("{}", response);
+    Ok(())
+}
+```
+
+## Installation
+
+Add to your `Cargo.toml`:
+
+```toml
+[dependencies]
+praisonai = "0.1"
+tokio = { version = "1", features = ["full"] }
+```
+
+## CLI Usage
+
+```bash
+# Install CLI
+cargo install praisonai-cli
+
+# Interactive chat
+praisonai-rust chat
+
+# Single-shot prompt
+praisonai-rust "What is 2+2?"
+
+# Run workflow from YAML
+praisonai-rust run agents.yaml
+```
+
+## Features
+
+- **Agent-Centric**: Every design decision centers on Agents
+- **Multi-Provider LLM**: OpenAI, Anthropic, Ollama support via rig-core
+- **Tool System**: `#[tool]` macro for easy tool creation
+- **Multi-Agent Workflows**: AgentTeam, AgentFlow patterns
+- **Memory**: Conversation history and long-term storage
+- **Async-First**: Built on Tokio for high performance
+
+## Crates
+
+| Crate | Description |
+|-------|-------------|
+| `praisonai` | Core library (Agent, Tools, Workflows) |
+| `praisonai-derive` | Proc macros (`#[tool]`) |
+| `praisonai-cli` | CLI binary |
+
+## API Parity with Python
+
+```python
+# Python
+from praisonaiagents import Agent, tool
+
+@tool
+def search(query: str) -> str:
+    """Search the web."""
+    return f"Results for: {query}"
+
+agent = Agent(instructions="Be helpful", tools=[search])
+response = agent.start("Hello!")
+```
+
+```rust
+// Rust
+use praisonai::{Agent, tool, Tool};
+
+#[tool(description = "Search the web")]
+async fn search(query: String) -> String {
+    format!("Results for: {}", query)
+}
+
+let agent = Agent::new()
+    .instructions("Be helpful")
+    .tool(SearchTool::new())
+    .build()?;
+let response = agent.chat("Hello!").await?;
+```

+//! PraisonAI Core - High-performance, agentic AI framework for Rust
+//!
+//! This crate provides the core functionality for building AI agents and multi-agent workflows.
+//!
+//! # Quick Start
+//!
+//! ```rust,ignore
+//! use praisonai::{Agent, tool};
+//!
+//! #[tool(description = "Search the web")]
+//! async fn search(query: String) -> String {
+//!     format!("Results for: {}", query)
+//! }
+//!
+//! #[tokio::main]
+//! async fn main() -> anyhow::Result<()> {
+//!     let agent = Agent::new()
+//!         .instructions("You are a helpful assistant")
+//!         .build();
+//!     
+//!     let response = agent.chat("Hello!").await?;
+//!     println!("{}", response);
+//!     Ok(())
+//! }
+//! ```
+//!
+//! # Architecture
+//!
+//! PraisonAI follows an agent-centric design with these core components:
+//!
+//! - **Agent**: The core execution unit that processes prompts and uses tools
+//! - **Tool**: Functions that agents can call to perform actions
+//! - **AgentTeam**: Coordinates multiple agents for complex workflows
+//! - **AgentFlow**: Defines workflow patterns (sequential, parallel, etc.)
+//! - **Memory**: Persists conversation history and context
+//!
+//! # Design Principles
+//!
+//! - **Agent-Centric**: Every design decision centers on Agents
+//! - **Protocol-Driven**: Traits define contracts, implementations are pluggable
+//! - **Minimal API**: Fewer parameters, sensible defaults
+//! - **Performance-First**: Lazy loading, optional dependencies
+//! - **Async-Safe**: All I/O operations are async

+# AGENTS.md - PraisonAI TypeScript SDK Comprehensive Guide
+
+> **For AI Agents and Developers**: This document provides the complete context needed to work with the PraisonAI TypeScript SDK, including design principles, architecture, repository structure, and implementation guidelines.
+
+---
+
+## 1. What is PraisonAI TypeScript?
+
+PraisonAI TypeScript is a **high-performance, agentic AI framework** for Node.js/JavaScript, designed for building production-ready AI agents and multi-agent workflows.
+
+### Core Philosophy
+
+```
+Simpler than competitors • More extensible • Faster • Agent-centric
+```
+
+| Principle | Description |
+|-----------|-------------|
+| **Agent-Centric** | Every design decision centers on Agents, workflows, sessions, tools, and memory |
+| **TypeScript-First** | Full type safety with excellent IntelliSense support |
+| **AI SDK Integration** | First-class support for Vercel AI SDK providers |
+| **Minimal API** | Fewer parameters, sensible defaults, explicit overrides |
+| **Performance-First** | Lazy loading, optional dependencies, no hot-path regressions |
+| **Multi-Agent Safe** | Concurrent execution, no shared mutable state issues |
+| **TDD Mandatory** | Tests first; failing tests prove gaps; passing tests prove fixes |
+| **Production-Ready** | Safe by default, async-safe, observable |
+

+

+
+## 3. Core Classes & Types
+
+### 3.1 Agent
+
+The primary class for creating AI agents:
+
+```typescript
+import { Agent } from 'praisonai';
+
+interface SimpleAgentConfig {
+  name?: string;           // Agent identifier
+  instructions: string;    // System prompt/instructions
+  llm?: string;            // Model: 'gpt-4o-mini', 'claude-3-opus', etc.
+  verbose?: boolean;       // Enable logging
+  stream?: boolean;        // Enable streaming
+  tools?: any[];           // Tool functions or FunctionTool instances
+  db?: DbAdapter;          // Database adapter for persistence
+  sessionId?: string;      // Session identifier
+  memory?: boolean;        // Enable memory
+  cache?: boolean;         // Enable response caching
+  telemetry?: boolean;     // Enable telemetry
+  role?: string;           // Agent role
+  goal?: string;           // Agent goal
+  backstory?: string;      // Agent backstory
+}
+```
+
+### 3.2 AgentTeam (Agents)
+
+Multi-agent orchestration:
+
+```typescript
+import { AgentTeam, Agent } from 'praisonai';
+
+interface AgentTeamConfig {
+  agents?: Agent[];                         // List of agents
+  tasks?: (Task | string)[];                // Tasks to execute
+  verbose?: boolean;                        // Enable logging
+  process?: 'sequential' | 'parallel' | 'hierarchical';
+  manager_llm?: string;                     // Manager LLM for hierarchical
+}
+
+// Aliases for Python parity
+export type Agents = AgentTeam;
+export type PraisonAIAgents = AgentTeam;
+```
+
+### 3.3 Task
+
+Task definition for workflows:
+
+```typescript
+import { Task, Agent } from 'praisonai';
+
+interface TaskConfig {
+  name: string;
+  description: string;
+  expected_output?: string;
+  agent?: Agent;
+  dependencies?: Task[];
+}
+```
+
+### 3.4 FunctionTool
+
+Type-safe tool creation:
+
+```typescript
+import { tool, FunctionTool } from 'praisonai';
+
+const myTool = tool({
+  name: 'search',
+  description: 'Search the web',
+  parameters: {
+    type: 'object',
+    properties: {
+      query: { type: 'string', description: 'Search query' }
+    },
+    required: ['query']
+  },
+  async execute({ query }) {
+    return `Results for: ${query}`;
+  }
+});
+```
+
+---
+
+## 4. Core Engineering Principles
+
+### 4.1 TypeScript-First Design
+
+```typescript
+// ✅ CORRECT: Full type safety
+interface ToolConfig<TParams = any, TResult = any> {
+  name: string;
+  description?: string;
+  parameters?: ToolParameters | any;
+  execute: (params: TParams, context?: ToolContext) => Promise<TResult> | TResult;
+}
+
+// ❌ WRONG: Using any without generics
+function createTool(config: any): any;
+```
+
+### 4.2 AI SDK Integration
+
+PraisonAI TypeScript provides first-class support for Vercel AI SDK:
+
+```typescript
+// Automatic backend resolution
+const agent = new Agent({
+  instructions: "Be helpful",
+  llm: "gpt-4o-mini"  // Resolves to AI SDK or native OpenAI
+});
+
+// Get backend info
+const backend = await agent.getBackend();
+const source = agent.getBackendSource(); // 'ai-sdk' | 'native' | 'custom'
+```
+
+### 4.3 Lazy Import Pattern
+
+```typescript
+// ✅ CORRECT: Lazy import for optional dependencies
+async function useFirecrawl() {
+  const { Firecrawl } = await import('@mendable/firecrawl-js');
+  return new Firecrawl();
+}
+
+// ❌ WRONG: Top-level import of optional dependency
+import { Firecrawl } from '@mendable/firecrawl-js';
+```
+
+### 4.4 Async/Await Pattern
+
+```typescript
+// Entry points: Always async
+async start(prompt: string): Promise<string>;
+async chat(prompt: string): Promise<string>;
+
+// Internal: Prefer async
+async processToolCalls(toolCalls: any[]): Promise<ToolResult[]>;
+
+// Utilities: Support both
+function parseArgs(args: string[]): ParsedArgs;
+async function loadConfig(path: string): Promise<Config>;
+```
+
+### 4.5 Error Handling
+
+```typescript
+// Custom error classes
+export class MissingDependencyError extends Error {
+  constructor(packageName: string, installCommand?: string) {
+    super(`Missing dependency: ${packageName}. Install with: ${installCommand}`);
+    this.name = 'MissingDependencyError';
+  }
+}
+
+export class MissingEnvVarError extends Error {
+  constructor(envVar: string) {
+    super(`Missing environment variable: ${envVar}`);
+    this.name = 'MissingEnvVarError';
+  }
+}
+```
+
+---
+
+## 5. Built-in Tools
+
+### 5.1 Tools Facade
+
+Access all built-in tools through the `tools` object:
+
+```typescript
+import { Agent, tools } from 'praisonai';
+
+const agent = new Agent({
+  instructions: "Research assistant",
+  tools: [
+    tools.tavily(),           // Web search
+    tools.codeExecution(),    // Code sandbox
+    tools.firecrawl(),        // Web scraping
+    tools.perplexity(),       // Perplexity search
+  ]
+});
+```
+
+### 5.2 Available Built-in Tools
+
+| Category | Tools |
+|----------|-------|
+| **Search** | `tavily()`, `tavilySearch()`, `tavilyExtract()`, `tavilyCrawl()` |
+| **Search** | `exa()`, `exaSearch()`, `perplexity()`, `perplexitySearch()` |
+| **Search** | `parallel()`, `parallelSearch()` (multi-provider) |
+| **Scraping** | `firecrawl()`, `firecrawlScrape()`, `firecrawlCrawl()` |
+| **Domain Search** | `valyuWebSearch()`, `valyuFinanceSearch()`, `valyuPaperSearch()` |
+| **Domain Search** | `valyuBioSearch()`, `valyuPatentSearch()`, `valyuSecSearch()` |
+| **Security** | `guard()`, `redact()`, `verify()` (superagent) |
+| **Code** | `codeExecution()`, `executeCode()`, `codeMode()` |
+| **Bedrock** | `bedrockCodeInterpreter()`, `bedrockBrowserNavigate()` |
+| **Vector** | `airweave()`, `airweaveSearch()` |
+| **Custom** | `custom()` for custom tool creation |
+
+---
+
+## 6. LLM Providers
+
+### 6.1 Supported Providers
+
+| Provider | Config Key | Models |
+|----------|------------|--------|
+| **OpenAI** | `openai/gpt-4o-mini` | gpt-4o, gpt-4o-mini, gpt-4-turbo |
+| **Anthropic** | `anthropic/claude-3-opus` | claude-3-opus, claude-3-sonnet, claude-3-haiku |
+| **Google** | `google/gemini-1.5-pro` | gemini-1.5-pro, gemini-1.5-flash |
+| **AI SDK** | via peer dependency | All AI SDK providers |
+
+### 6.2 Backend Resolution
+
+```typescript
+// Automatic resolution (AI SDK preferred)
+const agent = new Agent({ llm: "gpt-4o-mini" });
+
+// Force native provider
+const agent = new Agent({ llm: "openai/gpt-4o-mini" });
+
+// Check backend
+const backend = await agent.getBackend();
+console.log(agent.getBackendSource()); // 'ai-sdk' | 'native'
+```
+
+---
+
+## 7. Memory System
+
+### 7.1 Memory Types
+
+```typescript
+import { Memory, FileMemory, AutoMemory } from 'praisonai';
+
+// Basic memory
+const memory = new Memory({ sessionId: "user-123" });
+
+// File-based persistence
+const fileMemory = new FileMemory({
+  path: './data/memory.json',
+  sessionId: "user-123"
+});
+
+// Auto-detecting memory (short-term + long-term)
+const autoMemory = new AutoMemory({
+  enableShortTerm: true,
+  enableLongTerm: true,
+  provider: 'file'  // or 'sqlite', 'chroma'
+});
+```
+
+### 7.2 Memory with Agent
+
+```typescript
+import { Agent, db } from 'praisonai';
+
+const agent = new Agent({

+## 8. Hooks & Callbacks
+
+### 8.1 Agent Callbacks
+
+```typescript
+import { Agent, AgentCallbacks } from 'praisonai';
+
+const callbacks: AgentCallbacks = {
+  onStart: (agent, input) => console.log('Starting:', input),
+  onEnd: (agent, output) => console.log('Result:', output),
+  onToolCall: (agent, tool, args) => console.log('Calling:', tool),
+  onError: (agent, error) => console.error('Error:', error)
+};
+
+const agent = new Agent({
+  instructions: "Be helpful",
+  callbacks
+});
+```
+
+### 8.2 Workflow Hooks
+
+```typescript
+import { WorkflowHooks, createLoggingWorkflowHooks } from 'praisonai';

+
+---
+
+## 9. Workflows
+
+### 9.1 Task-Based Workflows

+    return summarize(research);
+  }
+});
+
+const workflow = new Workflow([researchTask, summaryTask]);
+const results = await workflow.run(createContext('workflow-1'));
+```
+
+### 9.2 Loop Pattern
+
+```typescript
+import { Loop, loop } from 'praisonai';
+
+const iterativeLoop = new Loop({

+| Agent class | `src/agent/simple.ts` |
+| Tool decorator | `src/tools/decorator.ts` |
+| Tool registry | `src/tools/registry/index.ts` |

+
+## 18. Naming Conventions
+
+```typescript
+// Registration/Mutation
+registerTool()       // Register tool to registry
+addHook()            // Add hook to manager
+
+// Retrieval
+getTool()            // Single tool by name

+class FunctionTool { }        // Tool class
+class ToolRegistry { }        // Registry class
+```
+
+---
+
+## 19. CLI Parity Requirement
+
+Every feature implemented must have a corresponding CLI representation:
+
+```typescript
+// Pattern: If you add an API, add a CLI command
+// Feature: Agent memory
+// API: await agent.clearMemory()
+// CLI: praisonai-ts memory clear --session <id>
+```
+
+| Feature | API | CLI Equivalent |
+|---------|-----|----------------|
+| Chat | `agent.chat(prompt)` | `praisonai-ts agent chat` |
+| Multi-agent | `team.start(task)` | `praisonai-ts agents run` |
+| Server | `createServer()` | `praisonai-ts serve` |
+
+---
+
+## 20. Verification Checklist
+
+For every feature/change, verify:
+
+- [ ] **Tests pass**: `npm test`
+- [ ] **TypeScript compiles**: `npm run build`
+- [ ] **Lint clean**: `npm run lint`
+- [ ] **No heavy imports at top-level**: Check lazy loading
+- [ ] **Async-safe**: Proper Promise handling
+- [ ] **Multi-agent safe**: No shared mutable state
+- [ ] **CLI works**: Command appears in `--help`
+- [ ] **Docs updated**: JSDoc with examples
+
+---
+
+## 21. Documentation Standards
+
+### 21.1 JSDoc Comments
+
+All public APIs must have JSDoc with examples:
+
+```typescript
+/**
+ * Creates an agent with the given configuration.
+ *
+ * @param config - Agent configuration
+ * @returns Configured agent instance
+ *
+ * @example
+ * ```typescript
+ * const agent = new Agent({
+ *   instructions: "Be helpful"
+ * });
+ * const response = await agent.chat("Hello");
+ * ```
+ */
+export class Agent { }
+```
+
+### 21.2 Mermaid Diagrams
+
+Use two-color scheme for architecture diagrams:
+- **Dark Red (#8B0000)**: Agents, inputs, outputs
+- **Teal (#189AB4)**: Tools, utilities
+
+```mermaid
+graph LR
+    A[Agent]:::agent --> B[Tool]:::tool
+    B --> C[Result]:::agent
+    classDef agent fill:#8B0000,color:#fff
+    classDef tool fill:#189AB4,color:#fff
+```
+
+### 21.3 Beginner-Friendly
+
+Documentation should make users feel: *"With just a few lines of code, I can do this!"*
+
+```typescript
+// 3 lines to chat with AI
+const agent = new Agent({ instructions: "Be helpful" });
+const response = await agent.chat("Hello");
+console.log(response);
+```
+
+---
+
+## 22. Free Core / Paid Upgrade Path
+
+Design features so that:
+
+| Aspect | Guideline |
+|--------|------------|
+| **Core remains free** | Essential agent functionality always open source |
+| **Clear upgrade path** | Support, cloud, managed services as paid options |
+| **Reduces friction** | Features reduce production risk, not just add functionality |
+| **Safe by default** | Simple to adopt, hard to misuse |
+
+---
+
+## 23. Implementation Checklist
+
+For every feature/change:
+
+- [ ] **TypeScript-first**: Full type definitions with generics
+- [ ] **No new deps**: Use optional dependencies only
+- [ ] **Lazy imports**: Heavy deps imported inside functions
+- [ ] **Naming**: Follow conventions (create*, get*, XConfig)
+- [ ] **Tests**: Write unit tests in `tests/`
+- [ ] **Docs**: Update this file and Mintlify docs
+- [ ] **Examples**: Add to `examples/` directory
+- [ ] **Async-safe**: Support async/await patterns
+- [ ] **Error handling**: Use custom error classes
+
+---
+
+## 24. Design Goals
+
+> Make PraisonAI the **best TypeScript agent framework in the world**
+
+1. **Simpler** than competitors (fewer concepts, cleaner API)
+2. **More extensible** (registry-driven, plugin-ready)
+3. **Faster** (lazy loading, AI SDK integration)
+4. **Type-safe** (full TypeScript support)
+5. **Production-ready** (observability, guardrails, MCP)
+
+---
+
+## 25. Python Parity
+
+This TypeScript SDK maintains feature parity with the Python SDK:
+
+| Python | TypeScript | Notes |
+|--------|------------|-------|
+| `Agent` | `Agent` | Same API |
+| `Agents` | `AgentTeam` | `Agents` is alias |
+| `Task` | `Task` | Same API |
+| `@tool` | `tool()` | Function vs decorator |
+| `Memory` | `Memory`, `FileMemory` | Same concepts |
+| `Hooks` | `HookManager` | Same events |
+| `Knowledge` | `Knowledge`, `RAG` | Same features |
+
