docs(readme): clarify /loop runs a prompt or custom command, not built-ins

fix(tui): address /loop review round 2 — ticker re-arm, self-paced command, resume guard
- stopLoop re-arms the poll ticker after removing one loop, so stopping one of several no longer strands the rest with no tick scheduled (jatmn). - a bare self-paced /command is rejected with a pointer to the interval form: self-paced drives a free-form goal via the playbook + LOOP: control line, which a custom command's expanded template never carries, so it would silently degrade to adaptive polling (jatmn). - /resume only tears loops down on an actual session-id change; /resume latest or /resume <currentID> can resolve to the already-active session, whose loops are its own, not a "previous" session's (CodeRabbit). - tests: skipped-behind-modal loop stays scheduled, footer carries the next-wake time, the confirmed /clear actually wipes the transcript, plus multi-loop stop keeping the ticker alive and self-paced-/command rejection.

-Only `name` and `description` are recognized in the frontmatter today. The `name` defaults to the directory name. Within a single skills root, duplicate names are resolved by lexicographic directory order. During an agent run, Zero loads the default skills directory before plugin skill roots; earlier roots win name collisions silently. Plugin-declared skills (section 6) are merged into the active agent run at plugin activation time, so bundled skills appear in the available skills list and can be loaded with the `skill` tool.

-# How Zero Works
-
-This document explains Zero's architecture at a high level: the layers, module
-boundaries, data flow, and runtime concepts behind the interactive TUI and the
-headless `zero exec` mode.
-
-It is written as a progressive map: each high-level section introduces the
-concepts you need for orientation, then points to the later section that explains
-the mechanics in more detail.
-
-## Big Picture
-
-Zero is a Go CLI application with two main user-facing surfaces:
-
- **Interactive TUI** (`zero`): a Bubble Tea application that renders chat,
-  tool cards, permission prompts, model/provider pickers, and session controls.
- **Headless exec** (`zero exec ...`): a scriptable command runner that uses the
-  same agent loop and tools, but writes text, JSON, or stream-JSON events.
-
-Both surfaces converge on the same core agent runtime:
-
-```mermaid
-flowchart TD
-    User[User / automation] --> CLI[cmd/zero -> internal/cli]
-
-    CLI --> TUI[Interactive TUI<br/>internal/tui]
-    CLI --> Exec[Headless exec<br/>internal/cli/exec.go]
-    CLI --> ACP[ACP / editor bridge<br/>internal/acp]
-
-    TUI --> Agent[Agent loop<br/>internal/agent]
-    Exec --> Agent
-    ACP --> Agent
-
-    Agent --> Provider[Provider runtime<br/>internal/zeroruntime.Provider]
-    Provider --> APIs[OpenAI / Anthropic / Gemini / compatible APIs]
-
-    Agent --> Registry[Tool registry<br/>internal/tools.Registry]
-    Registry --> CoreTools[Core tools<br/>read/edit/shell/search/plan]
-    Registry --> MCP[MCP tools<br/>internal/mcp]
-    Registry --> Specialists[Specialist tools<br/>internal/specialist]
-    Registry --> Plugins[Plugin tools<br/>internal/plugins]
-    Registry --> LocalControl[Browser / terminal / desktop helpers]
-
-    Agent --> Sandbox[Permission + sandbox engine<br/>internal/sandbox]
-    Agent --> Hooks[Hooks dispatcher<br/>internal/hooks]
-    Agent --> Sessions[Session event store<br/>internal/sessions]
-```
-
-The important split is:
-
- `internal/tui` is the **presentation layer**. For the mechanics, see
-  [Presentation Layer: Bubble Tea TUI](#presentation-layer-bubble-tea-tui) and
-  [How the TUI and Agent Loop Connect](#how-the-tui-and-agent-loop-connect).
- `internal/agent` is the **reasoning/tool loop**. For the per-turn mechanics,
-  see [Agent Loop](#agent-loop), [Tool Execution Lifecycle](#tool-execution-lifecycle),
-  and [Context Budget and Compaction](#context-budget-and-compaction).
- `internal/tools`, `internal/sandbox`, and provider packages are the **runtime
-  capability layer**. For the details, see [Runtime Provider Layer](#runtime-provider-layer),
-  [Tools and Capabilities](#tools-and-capabilities), and
-  [Permission and Sandbox Model](#permission-and-sandbox-model).
- `internal/sessions` is the **durable event log** used for resume, fork,
-  rewind, sub-agents, and history. See [Session Storage and History](#session-storage-and-history).
-
-## Architecture Spine
-
-The easiest way to understand Zero is not as a set of independent packages, but
-as one spine with several mechanisms attached to it:
-
-```mermaid
-flowchart LR
-    Surface[Surface<br/>TUI / exec / ACP] --> Run[Run request<br/>prompt + runtime options]
-    Run --> Agent[Agent loop<br/>turns, tools, recovery]
-    Agent --> Capabilities[Capabilities<br/>providers + tools + sandbox]
-    Capabilities --> Events[Runtime events<br/>text, tool calls, permissions, usage]
-    Events --> Surface
-    Events --> Sessions[Session log<br/>resume, fork, rewind, history]
-
-    Config[Config / guidelines / skills] --> Run
-    Extensions[MCP / specialists / plugins / hooks] --> Capabilities
-```
-
-The **TUI + agent loop** is the main story because it explains the normal user
-experience: type a prompt, watch the model stream, approve tool use, see file
-changes, and receive a final answer. Other mechanisms are still important, but
-most of them attach to the same spine:
-
-| Mechanism | Where it attaches | What it changes |
-| --- | --- | --- |
-| Config, provider profiles, model registry | Before a run starts | Which provider/model is used and what defaults apply. |
-| Project/user guidelines, skills, specialists context | Prompt construction | What instructions and available capabilities the model sees. |
-| Tool registry, MCP, plugins, local-control helpers | Capability layer | Which actions the model may request. |
-| Permission policy, sandbox, command-prefix grants | Tool execution | Whether a requested action can run, needs approval, or is denied. |
-| Hooks | Tool lifecycle | Optional before/after observers or blockers around tool calls. |
-| Sessions, checkpoints, compaction metadata | Event persistence/context | What can be resumed, forked, rewound, or summarized for later turns. |
-| Stream-JSON | Surface layer | How the same runtime events are emitted for automation instead of rendered in the TUI. |
-
-So this document focuses first on the TUI/agent-loop bridge, then explains the
-supporting mechanisms in terms of where they connect to that bridge.
-
-Use this as the reading path:
-
-| If you see this concept in a high-level flow | Read this detail section |
-| --- | --- |
-| Surface submits a run | [Startup Flow](#startup-flow), then [How the TUI and Agent Loop Connect](#how-the-tui-and-agent-loop-connect) |
-| Agent builds context and advances turns | [Agent Loop](#agent-loop) |
-| “Maybe compact context” | [Context Budget and Compaction](#context-budget-and-compaction) |
-| Model requests a tool | [Tool Execution Lifecycle](#tool-execution-lifecycle), then [Tools and Capabilities](#tools-and-capabilities) |
-| Tool needs approval or sandbox access | [Permission and Sandbox Model](#permission-and-sandbox-model) |
-| Events appear in the UI or stream-JSON | [How the TUI and Agent Loop Connect](#how-the-tui-and-agent-loop-connect), [Stream-JSON Protocol](#stream-json-protocol) |
-| Resume, fork, rewind, or sub-agent history | [Session Storage and History](#session-storage-and-history) |
-
-## Main Packages
-
-The sections above describe the architecture in concepts. If you want to connect
-those concepts to implementation details, use this table as the code map before
-reading the deeper flows below.
-
-| Package | Role |
-| --- | --- |
-| `cmd/zero` | Tiny binary entrypoint; calls `internal/cli.Run`. |
-| `internal/cli` | Command parsing, config resolution, provider creation, registry setup, TUI/exec/ACP launch paths. |
-| `internal/tui` | Bubble Tea model/update/view code, transcript rendering, composer, prompts, slash commands, setup wizard. |
-| `internal/agent` | Core loop that sends messages to the model, streams output, executes tools, handles permissions, compaction, retries, and final answers. |
-| `internal/zeroruntime` | Provider-neutral message, tool-call, stream, usage, and image types. Providers implement `Provider.StreamCompletion`. |
-| `internal/providers` | Factory that turns a resolved provider profile into an OpenAI, Anthropic, Gemini, Codex, or compatible provider adapter. |
-| `internal/tools` | Tool interface, registry, core read/write/shell/network tools, local-control wrappers, tool safety metadata, redaction, output ceilings. |
-| `internal/sandbox` | Permission policy, path/network checks, grant store, command-prefix approvals, and platform sandbox backends. |
-| `internal/sessions` | Local append-only session storage: `metadata.json` + `events.jsonl`. |
-| `internal/config` | User/project config resolution, active provider, preferences, sandbox/tool settings. |
-| `internal/mcp` | MCP server config, client runtime, permission store, and MCP tool registration. |
-| `internal/specialist` / `internal/swarm` | Sub-agent manifests and team/member orchestration exposed as tools. |
-| `internal/localcontrol` / `internal/browser` | Runtime helpers used by config-gated local-control tool wrappers. |
-| `internal/plugins` / `internal/skills` / `internal/hooks` | Extension surfaces loaded into the agent context, tool registry, or tool lifecycle. |
-| `internal/streamjson` | Machine-readable protocol for `zero exec --input-format/--output-format stream-json`. |
-
-## Startup Flow
-
-### Interactive TUI (`zero`)
-
-```mermaid
-sequenceDiagram
-    participant Main as cmd/zero
-    participant CLI as internal/cli
-    participant Config as internal/config
-    participant TUI as internal/tui
-    participant Agent as internal/agent
-
-    Main->>CLI: Run(args)
-    CLI->>Config: resolve config for workspace
-    CLI->>CLI: build provider
-    CLI->>CLI: build tool registry
-    CLI->>CLI: register core, config-gated local-control, specialists, MCP, plugins
-    CLI->>CLI: create sandbox engine + session store
-    CLI->>TUI: run Bubble Tea with Options
-    TUI->>TUI: Init / Update / View event loop
-    TUI->>Agent: agent.Run on submitted prompt
-```
-
-The TUI owns terminal interaction. It tracks composer state, transcript rows,
-scrolling, permission dialogs, model/provider pickers, setup wizard state, and
-visual updates. When the user submits a prompt, the TUI builds `agent.Options`
-with callbacks like `OnText`, `OnToolCall`, `OnToolResult`, `OnPermission`,
-`OnAskUser`, and `OnUsage`. Those callbacks convert runtime events into visible
-transcript rows and session events.
-
-### Headless exec (`zero exec`)
-
-```mermaid
-flowchart TD
-    A[Parse exec flags] --> B[Resolve config + provider]
-    B --> C[Build tool registry]
-    C --> D[Resolve prompt / stream-json input / images]
-    D --> E[Prepare or resume session]
-    E --> F[Create stream-json/text/json writer]
-    F --> G[agent.Run]
-    G --> H[Write final output and exit code]
-```
-
-`zero exec` uses the same `agent.Run` loop as the TUI, but without interactive
-terminal state. It can persist sessions, resume/fork existing sessions, run in
-stream-JSON mode for automation, and always requires a stronger completion
-signal so a no-tool assistant response is not treated as success while work is
-still pending.
-
-## Agent Loop
-
-The core loop lives in `internal/agent.Run`. Conceptually, every turn follows
-this cycle:
-
-```mermaid
-flowchart TD
-    Start[Build system prompt + user prompt] --> Expose[Partition visible tools]
-    Expose --> Compact[Maybe compact context]
-    Compact --> Request[Send CompletionRequest to provider]
-    Request --> Stream[Collect streamed text, reasoning, usage, tool calls]
-
-    Stream --> HasTools{Tool calls?}
-    HasTools -- No --> FinalCheck{Final answer acceptable?}
-    FinalCheck -- Yes --> Done[Return Result]
-    FinalCheck -- No --> Nudge[Append user nudge and continue]
-
-    HasTools -- Yes --> Execute[Execute tool calls]
-    Execute --> Permission[Permission / sandbox / hooks]
-    Permission --> ToolResult[Append tool result messages]
-    ToolResult --> Diagnostics[Post-edit diagnostics / self-correct]
-    Diagnostics --> Expose
-```
-
-Key responsibilities of the loop:
-
-1. **Build prompt state** — combines the system prompt, project/user guidelines,
-   loaded skills/specialist instructions, the current user prompt, and images. The
-   resulting message list is the model-facing context that later tool results are
-   appended to. Resumed session history is replayed by the caller before a new run,
-   not passed as a separate `agent.Run` history field.
-2. **Expose tools** — starts from the registry built by the CLI, then filters
-   tool definitions by permission mode, enabled or disabled filters, and
-   deferred-loading rules. Tool schemas also count toward context budget, so they
-   matter for compaction decisions.
-3. **Call provider** — sends a provider-neutral `zeroruntime.CompletionRequest`.
-4. **Stream events** — forwards text, reasoning, tool-call deltas, and usage to
-   the caller via callbacks.
-5. **Execute tools** — decodes tool arguments, checks filters, applies
-   permissions and sandbox policy, dispatches hooks, runs the registered tool,
-   redacts output, and appends a tool message. See
-   [Tool Execution Lifecycle](#tool-execution-lifecycle).
-6. **Recover and guard** — handles malformed tool calls, repeated failures,
-   empty turns, context pressure, stream reconnect/retry, and max-turn fallback.
-   Context pressure is handled by [Context Budget and Compaction](#context-budget-and-compaction).
-7. **Finalize** — returns a final answer or a structured incomplete/stop reason.
-
-The model never directly mutates the workspace. It asks for tool calls; Zero
-validates and executes those calls through the registry, permission policy, and
-sandbox engine.
-
-## Tool Execution Lifecycle
-
-A tool call is part of the model conversation, not a side channel that bypasses
-it. The model proposes an action, Zero decides whether that action is allowed to
-run, the tool returns a structured result, and that result becomes context for the
-next provider request.
-
-```mermaid

-    participant Agent as agent.Run
-    participant Policy as filters + permissions + sandbox

-    end
-
-    Agent->>Model: next request includes prior assistant tool_call + tool result
-    Model-->>Agent: continue with more tools or final answer
-```
-
-Conceptually, one requested tool goes through these phases:
-
-1. **Proposal** — the provider streams assistant content and may emit one or more
-   tool calls. Zero can show the partial tool arguments in the TUI while they are
-   still streaming, but nothing has executed yet.
-2. **Decode and gate** — the agent validates JSON arguments, checks whether the
-   tool is enabled, applies permission mode, asks the sandbox engine about path,
-   network, shell, or command-prefix constraints, and may invoke permission
-   callbacks.
-3. **Execute** — the selected registry entry runs locally, through MCP, as a
-   specialist/sub-agent, or through a plugin/local-control helper. Hooks can run
-   before or after this step.
-4. **Normalize result** — Zero turns the outcome into an agent `ToolResult`: a
-   success, failure, denial, cancellation, timeout, or validation error with
-   output/metadata that may be redacted or truncated.
-5. **Append to context** — the result is appended as a tool-result message paired
-   with the assistant tool call. The next model request includes that result, so
-   the model can inspect it and decide what to do next.
-6. **Render and persist** — the result is surfaced to the TUI, stream-JSON
-   writer, or ACP client. TUI and exec record rich tool/session events for
-   resume/history; ACP currently persists conversational messages and streams
-   tool/permission updates to the client.
-
-Tool success and failure are both informative context. A successful `read_file`
-result gives the model file contents; a failed `edit_file` result gives the model
-an error such as “old string not found”; a denied shell command tells the model
-that the action is not currently permitted. The model is expected to use that
-feedback to continue, choose another tool, ask the user, or explain the blocker.
-
-The judgement that “information is sufficient” is made by the model, not by the
-TUI. Zero controls the loop mechanics: it keeps appending messages, enforces
-safety, retries or nudges around malformed/empty/incomplete turns, and stops on
-hard limits. But the semantic decision to call another tool versus produce a
-final answer comes from the next provider response. In other words:
-
-```mermaid
-flowchart TD
-    Result[Tool result appended to conversation] --> Next[Next provider request]
-    Next --> Decide{Model response}
-    Decide -- More information/action needed --> MoreTools[Request another tool]
-    MoreTools --> Result
-    Decide -- User input needed --> AskUser[Call ask_user or explain question]
-    AskUser --> Result
-    Decide -- Enough information --> Final[Final assistant answer]
-    Decide -- Invalid / empty / unsafe --> Guard[Agent guardrail, retry, denial, or stop reason]
-    Guard --> Next
-```
-
-This is why tool output is usually more than UI decoration. It is part of the
-working memory for the next model turn, subject to context-window pressure and
-compaction. The TUI may summarize or prettify it for the user, but the agent loop
-also stores the machine-facing result that the model sees.
-
-## Context Budget and Compaction
-
-The `Maybe compact context` step in the agent-loop diagram is Zero's context-window
-pressure valve. It is not a separate memory engine; it rewrites the current
-model-facing conversation so the next provider request fits within the configured
-context window.
-
-Compaction is enabled only when the run knows a positive `ContextWindow`. When it
-is enabled, the loop does this near the top of each turn:
-
-```mermaid
-flowchart TD
-    Tools[Partition visible tools] --> Estimate[Estimate messages + tool-definition tokens]
-    Estimate --> Under{Under threshold?}
-    Under -- Yes --> Keep[Keep context as-is]
-    Under -- No --> Grown{Grown past low-water mark?}
-    Grown -- No --> Keep
-    Grown -- Yes --> Prune[Prune stale large tool outputs]
-    Prune --> Recheck{Back under threshold?}
-    Recheck -- Yes --> KeepPruned[Use pruned context]
-    Recheck -- No --> Summarize[Summarize oldest middle]
-    Summarize --> Replace[system messages + summary + recent suffix]
-```
-
-The trigger is intentionally approximate:
-
- Zero estimates request size using message text, images, tool-call arguments, and
-  the tool definitions advertised on that turn.
- The proactive threshold is roughly **two-thirds of the context window**.
- Provider usage from completed turns is used to calibrate the rough estimate over
-  time, so the budget gauge and compaction decision track the provider more
-  closely after a few turns.
- A low-water mark prevents the loop from re-summarizing the same already-compacted
-  history on every turn.
-
-When compaction actually runs, it tries to preserve the parts most likely to be
-needed by the model:
-
- leading system messages stay verbatim;
- the most recent turns stay verbatim (`CompactionPreserveLast`, defaulting to the
-  agent's normal preserve count);
- the preserved suffix is widened to a provider-valid turn boundary so tool-result
-  messages are not replayed without their corresponding assistant tool call;
- the older middle is summarized into one user-role message labeled
-  `[Summary of earlier conversation]`;
- structured state that should not be paraphrased away, such as active plan/loaded
-  skill state, is preserved alongside the prose summary.
-
-There are two compaction paths:
-
-1. **Proactive compaction** runs before the provider call when the estimated
-   request is over threshold.
-2. **Reactive compaction** runs after a provider returns a context-limit style
-   error. Zero compacts once and retries that same turn; if the provider still
-   rejects the request, the error is surfaced rather than looping forever.
-
-Compaction failures are conservative. If the summarizer fails during proactive
-compaction, Zero keeps the original messages and tries to continue. It does not
-drop conversation history just to make room.
-
-## Presentation Layer: Bubble Tea TUI
-
-`internal/tui` is a Bubble Tea application. The usual Bubble Tea shape applies:
-
-```mermaid
-flowchart LR
-    Init[model.Init] --> Update[model.Update]
-    Update --> View[model.View]
-    View --> Terminal[Terminal frame]
-    Terminal --> Msg[tea.Msg: key, mouse, window, agent event]
-    Msg --> Update
-```
-
-The TUI is intentionally not the agent brain. It is responsible for:
-
- collecting user input from the composer;
- rendering assistant text, reasoning, tool cards, permissions, plans, usage,
-  files, and sidebars;
- handling slash commands and modal surfaces;
- converting agent callbacks into Bubble Tea messages;
- persisting visible session events;
- allowing live provider/model/permission changes.
-
-When a prompt is submitted, the TUI starts a background command that invokes
-`agent.Run`. Streaming callbacks send messages back into the Bubble Tea update
-loop, so rendering remains responsive while the agent is working.
-
-## How the TUI and Agent Loop Connect
-
-A common source of confusion is that Zero has two event loops running at once:
-
-1. **Bubble Tea loop** — owns terminal input, in-memory UI state, and frames.
-2. **Agent loop** — owns model turns, tool execution, permissions, retries, and
-   stop conditions.
-
-They are connected by `tea.Cmd` and `agent.Options` callbacks. The TUI never
-runs provider/tool logic directly inside `Update`; instead, submit handling gates
-and dispatches a prompt, the TUI starts a background command, and that command
-calls `agent.Run` with callbacks that send runtime events back to the Bubble Tea
-program. Function names in this section are illustrative code anchors, not API
-boundaries.

-    TUI->>TUI: mark run complete, flush rows/events, unlock composer
-```
-
-In the TUI path, the same event can have three representations:
-
-| Runtime thing | Agent representation | TUI representation | Session representation |
-| --- | --- | --- | --- |
-| Assistant text | streamed provider text forwarded through `OnText` | incremental assistant row text | assistant message event |
-| Reasoning preview | `OnReasoning` callback | collapsible/preview reasoning row | usually not the same as final assistant text |
-| Tool call | `agent.ToolCall` from collected provider stream | tool card, specialist card, or plan panel update | `EventToolCall` |
-| Tool result | `agent.ToolResult` | result card/status, changed files, plan/specialist updates | `EventToolResult` |
-| Permission prompt/audit | `PermissionRequest` / `PermissionEvent` | modal prompt or permission row | permission request/decision events |
-| Usage/context | provider usage + measured context | context gauge / usage metadata | usage event |
-
-### One interactive turn, end to end
-
-For a normal prompt in the interactive TUI:
-
-1. Submit handling validates composer state and command gates, then dispatches
-   the prompt to the launch path.
-2. The launch path appends immediate UI rows, creates a cancellable run context,
-   and starts `runAgent` as a `tea.Cmd`; run bookkeeping assigns the `runID` used
-   to correlate later events.
-3. `runAgentWithOptions` copies the current UI-controlled runtime choices into
-   `agent.Options`: provider/model labels, permission mode, cwd, session ID,
-   images, registry, response style, context window, and self-correction hooks.
-4. The command wraps agent callbacks. For example:
-   - `OnText` sends incremental assistant text into the TUI message sink.
-   - `OnToolCallStart` / `OnToolCallDelta` show live tool-argument streaming.
-   - `OnToolCall` creates visible tool rows and appends session events.
-   - `OnToolResult` creates result rows, updates plan/specialist side panels, and
-     records changed files.
-   - `OnPermissionRequest` sends a prompt to the TUI and blocks the agent loop
-     until the user answers or the run context is cancelled.
-   - `OnAskUser` does the same for model-initiated clarification questions.
-5. `agent.Run` builds provider-neutral messages and tool definitions, streams a
-   provider response, executes any requested tools through the registry/sandbox,
-   appends tool results back into the model conversation, and repeats until it has
-   a final answer or a stop condition.
-6. When `agent.Run` returns, the command emits `agentResponseMsg`. The Bubble Tea
-   loop marks the run complete, flushes queued rows/session events, updates usage
-   and file state, and re-enables the composer.
-
-The important architectural point: **the TUI is stateful and reactive, but the
-agent loop is the source of runtime truth for model/tool progress**. Presentation
-state is derived from callback events and persisted session events; workspace
-changes happen only through tools executed by the agent runtime.
-
-### Feature flows use the same bridge
-
-For one interactive turn, the supporting systems do not run beside the TUI/agent
-loop; they run inside or around it:
-
-```mermaid
-flowchart TD
-    Submit[TUI submit] --> Options[Build agent.Options]
-    Options --> Context[Assemble context<br/>config, guidelines, history, skills]
-    Context --> ProviderCall[Provider stream]
-    ProviderCall --> StreamEvents[Text/reasoning/tool-call events]
-    StreamEvents --> Render[TUI render callbacks]
-
-    ProviderCall --> ToolCall{Tool call?}
-    ToolCall -- No --> Final[Final response]
-    ToolCall -- Yes --> ToolGate[Tool gate<br/>filters, permissions, sandbox]
-    ToolGate --> HooksBefore[beforeTool hooks]
-    HooksBefore --> Execute[Tool / MCP / specialist / plugin]
-    Execute --> HooksAfter[afterTool hooks]

-    ToolResult --> Persist[Session events]
-    ToolResult --> Context
-
-    Final --> Persist
-    Persist --> Resume[Resume / fork / rewind / parent metadata]
-```
-
-Most interactive features are variations of that same bridge rather than separate
-architectures:
-
- **Slash commands** either mutate TUI state directly (`/model`, `/permission`,
-  `/help`) or start short `tea.Cmd` jobs that later return a message to `Update`
-  (`/doctor`, `/search`, `/compact`, session commands).
- **Permissions** sit between a model-requested tool call and actual execution:
-  the agent blocks on `OnPermissionRequest`, the TUI surfaces a modal and sends
-  the decision back through a channel, and the session log records the
-  request/decision events.
- **Plans, specialists/sub-agents, and ask-user prompts** all follow the same
-  runtime pattern: the model requests a capability, the agent records the
-  call/result in its conversation, and the TUI mirrors the visible state as plan
-  panels, specialist cards, or question forms. Specialist session metadata can
-  carry parent/root and sub-agent/spec fields, with richer linkage depending on
-  the specialist or swarm path.
- **Streaming tool writes** start as provider tool-call deltas before execution;
-  the TUI shows the arguments live, then replaces/augments them with the actual
-  `ToolResult` after the tool runs.
- **Compaction** is an agent-loop context-management step; the TUI may show that
-  it happened, but the purpose is to keep the next provider request within budget.
- **Stream-JSON** is another surface over the same callbacks: `zero exec`
-  serializes the events as JSON protocol events instead of Bubble Tea views.
-
-So a feature-specific deep dive should usually explain: what user event starts it,
-which `tea.Msg`/callback carries it, which agent/tool event is authoritative, and
-which session events make it resumable.
-
-## Runtime Provider Layer
-
-Providers are hidden behind this interface in `internal/zeroruntime`:
-
-```go
-type Provider interface {
-    StreamCompletion(ctx context.Context, request CompletionRequest) (<-chan StreamEvent, error)
-}
-```
-
-The agent loop only knows about provider-neutral messages, tool definitions,
-stream events, reasoning blocks, images, and token usage. Provider adapters in
-`internal/providers/*` translate those neutral types to provider-specific APIs:
-
- OpenAI and OpenAI-compatible APIs;
- Anthropic and Anthropic-compatible APIs;
- Gemini;
- Codex / ChatGPT OAuth-backed runtime.
-
-`internal/providers.New` resolves the configured model through the model
-registry/catalog, normalizes API model IDs and base URLs, attaches API keys or
-OAuth resolvers, and returns the concrete adapter.
-
-## Tools and Capabilities
-
-Tools implement a common interface and are registered by name in
-`internal/tools.Registry`.
-
-```mermaid
-flowchart TD
-    AgentToolCall[Tool call from model] --> Decode[Decode JSON args]
-    Decode --> Filter[Enabled/disabled + permission-mode filter]
-    Filter --> Precheck[Pre-permission rejecters]
-    Precheck --> SandboxEval[Sandbox Evaluate]
-    SandboxEval --> Prompt{Needs user approval?}
-    Prompt -- Yes --> Decision[Permission callback]
-    Prompt -- No --> Run[Registry.RunWithOptions]
-    Decision --> Run
-    Run --> Redact[Redact secrets + enforce output ceiling]
-    Redact --> Message[Return tool result to model]
-```
-
-Core tool groups include:
-
- **Read-only tools**: file reads, directory listing, glob, grep, LSP navigation,
-  skills, `ask_user`, permission requests.
- **Write tools**: `write_file`, `edit_file`, `apply_patch`, `update_plan`.
- **Shell tools**: `exec_command`, `write_stdin`, legacy `bash`.
- **Network tools**: `web_fetch` and optional web search backend.
- **Local-control tools**: config-gated wrappers for browser, terminal, desktop,
-  and artifact helpers backed by packages such as `internal/localcontrol` and
-  `internal/browser`.
- **Extension tools**: MCP tools, specialists/sub-agents, swarm tools, plugins.
-
-Tool definitions include safety metadata: side-effect class, permission level,
-reason, and whether prompt-gated tools are advertised in auto-like modes. The
-agent uses this metadata plus per-turn filters and deferred-loading state to
-choose which registered tools the model can see and whether a call can run
-immediately.
-
-## Permission and Sandbox Model
-
-Zero has two related but separate checks:
-
-1. **Tool permission metadata** says whether a tool is allowed, denied, or needs
-   approval.
-2. **Sandbox policy** evaluates the actual request: path scope, network access,
-   destructive shell patterns, explicit escalation, persistent/session grants,
-   and platform isolation availability.
-
-```mermaid
-flowchart TD
-    Call[Tool call] --> Safety[Tool Safety metadata]
-    Call --> Scope[Workspace/additional roots scope]
-    Safety --> Engine[Sandbox Engine Evaluate]
-    Scope --> Engine
-    Engine --> Allow[Allow]
-    Engine --> Prompt[Prompt user]
-    Engine --> Deny[Deny]
-    Prompt --> Grant[Turn/session/persistent grant]
-    Grant --> Execute[Execute tool]
-    Allow --> Execute
-    Deny --> Result[Return denied tool result]
-```
-
-The sandbox engine can:
-
- auto-allow workspace writes for safe file-edit tools;
- block reads/writes outside the allowed scope;
- prompt for recoverable outside-workspace access;
- deny or prompt for network depending on policy;
- detect destructive shell commands;
- run shell commands through a platform backend when available;
- remember session or persistent grants;
- support narrow command-prefix approvals.
-
-The user-facing TUI and `zero exec` mode both route permission requests through
-callbacks, but the TUI can show interactive modals while headless mode generally
-returns non-interactive fallback behavior unless a protocol/client handles it.
-
-## Session Storage and History
-
-Sessions live locally under Zero's data directory. A session directory contains:
-
- `metadata.json` — session ID, title, cwd, provider/model, parent/root IDs,
-  spec/sub-agent fields, timestamps, and event count.
- `events.jsonl` — append-only event log with messages, tool calls/results,
-  permissions, usage, checkpoints, forks, compaction, and specs. TUI and exec use
-  the richer event stream; ACP currently records conversational message history
-  while streaming tool and permission updates to the client.
-
-```mermaid
-flowchart LR
-    TUI[TUI callbacks] --> Store[internal/sessions.Store]
-    Exec[exec recorder] --> Store
-    Store --> Metadata[metadata.json]
-    Store --> Events[events.jsonl]
-    Events --> Resume[resume]
-    Events --> Fork[fork]
-    Events --> Rewind[rewind/checkpoints]
-    Events --> Children[parent/root metadata]
-```
-
-This is why sessions can be resumed, forked, rewound, and inspected without a
-remote service. Zero stores the local event history; providers only receive the
-messages needed for the current completion request.
-
-## Stream-JSON Protocol
-
-`zero exec --output-format stream-json` emits newline-delimited JSON events for
-integrations and CI. The protocol is implemented in `internal/streamjson` and is
-specified in [STREAM_JSON_PROTOCOL.md](STREAM_JSON_PROTOCOL.md).
-
-Common output event types include:
-
- `run_start`, `text`, `reasoning`, `tool_call`, `tool_result`;
- `permission`, `permission_request`, `permission_decision`;
- `checkpoint`, `restore`, `usage`, `final`, `warning`, `error`, `run_end`.
-
-Input stream-JSON can provide `prompt` or `message` events and image payloads.
-The CLI parses those events, resolves a single prompt, validates/decodes images,
-and passes the result into the same agent loop used everywhere else.
-
-## Extensibility Flow
-
-Zero's extension surfaces are loaded before the agent loop starts:
-
-```mermaid
-flowchart TD
-    Config[Config resolution] --> Registry[Tool registry]
-    Registry --> Core[Core tools]
-    Registry --> MCP[MCP server tools]
-    Registry --> Specialist[Specialist / Task tools]
-    Registry --> Plugin[Plugin tools]
-
-    Config --> Prompt[System prompt context]
-    Prompt --> Guidelines[AGENTS.md / ZERO.md]
-    Prompt --> Skills[Skills list]
-    Prompt --> SpecialistContext[Specialist descriptions]
-
-    ToolLifecycle[Tool lifecycle] --> Hooks[beforeTool / afterTool hooks]
-```
-
- **Project/user guidelines** become prompt context.
- **Skills** are instruction packs the model can load on demand.
- **Specialists** are sub-agents callable through the `Task` tool.
- **MCP servers** contribute external tools.
- **Plugins** can add tools, hooks, and skill roots. Bootstrap merges plugin skill
-  roots into the runtime skill tool and prompt-visible skill list; the base
-  `internal/skills` scanner still scans one root at a time.
- **Hooks** can observe or block tool lifecycle events.
-
-## End-to-End Data Flow
-
-A typical interactive edit request looks like this:
-
-```mermaid
-sequenceDiagram
-    participant U as User
-    participant T as TUI
-    participant A as Agent loop
-    participant P as Provider
-    participant R as Tool registry
-    participant S as Sandbox
-    participant FS as Workspace/session files
-
-    U->>T: Type prompt and press Enter
-    T->>A: agent.Run(prompt, provider, options)
-    A->>P: CompletionRequest(messages, tool definitions)
-    P-->>A: Stream text + tool call edit_file
-    A->>S: Evaluate edit_file args
-    S-->>A: allow/prompt/deny decision
-    A->>T: permission callback if prompt needed
-    T-->>A: user decision
-    A->>R: Run edit_file
-    R->>FS: Write workspace file
-    R-->>A: Tool result + changed files
-    A->>P: Next CompletionRequest with tool result
-    P-->>A: Final answer
-    A-->>T: Result + callbacks
-    T->>FS: Append session events
-    T-->>U: Render final transcript
-```
-
-The same request in `zero exec` follows the same provider/tool/sandbox path, but
-streaming events are written to stdout/stderr instead of rendered in Bubble Tea.
-
-## Mental Model
-
-When you work on Zero, start by locating the change on the four-layer spine from
-[Architecture Spine](#architecture-spine) — Surface, Agent loop, Capabilities,
-Persistence — then jump to the package that owns that boundary:
-
- UI behavior? Start in `internal/tui`.
- Command-line behavior? Start in `internal/cli`.
- Model/tool-turn behavior? Start in `internal/agent`.
- A new capability? Register a tool in `internal/tools` or an extension surface.
- Safety policy? Start in `internal/sandbox` and agent permission wiring.
- Resume/history behavior? Start in `internal/sessions` and session recorders.

Vasanthdev2004	ac25352e12	fix(tui): address /loop review round 2 — ticker re-arm, self-paced command, resume guard - stopLoop re-arms the poll ticker after removing one loop, so stopping one of several no longer strands the rest with no tick scheduled (jatmn). - a bare self-paced /command is rejected with a pointer to the interval form: self-paced drives a free-form goal via the playbook + LOOP: control line, which a custom command's expanded template never carries, so it would silently degrade to adaptive polling (jatmn). - /resume only tears loops down on an actual session-id change; /resume latest or /resume <currentID> can resolve to the already-active session, whose loops are its own, not a "previous" session's (CodeRabbit). - tests: skipped-behind-modal loop stays scheduled, footer carries the next-wake time, the confirmed /clear actually wipes the transcript, plus multi-loop stop keeping the ticker alive and self-paced-/command rejection.	2026-07-06 08:53:04 +05:30
Vasanthdev2004	de7f0b6a5b	fix(tui): finish /loop v1 — real self-paced completion, session scope, leave gate Response to the review. The self-paced path was the real gap: it advertised model-chosen completion but nothing ever wrote the done/next-wake fields, so it was just adaptive polling dressed up. Replaced that with an actual control channel — each self-paced iteration runs a short maintenance playbook and ends its reply with a control line (LOOP: DONE / LOOP: CONTINUE [interval]) that advanceLoop parses to stop the loop or pick the next wake. The two dead model fields are gone; done and next-wake now come from the model's output. Rest of the review: - loops stop on a session switch (/new, /resume) instead of firing the previous conversation's prompt into the new one - validateLoopTarget resolves custom /commands up front and rejects unknowns, so a mistyped `/loop 5m /nope` isn't scheduled and then re-sent as literal text - a one-shot confirm gates /clear and /quit while loops are active - age-based auto-expire (24h) next to the iteration cap - the two CodeRabbit test nits (HasPrefix footer check, bare `/loop stop` on a single loop) Hardening from a self-review pass over the above: - normalize CRLF and allow a trailing note on the control line, so `LOOP: DONE — all clean` and \r\n replies still stop the loop - disarm the leave-confirm before the queue/exit early returns, so an interposed prompt can't leave it falsely armed - a loop no longer fires behind an open picker/modal; a run launched behind the /resume picker would otherwise complete into whatever session you switch to	2026-07-06 08:53:04 +05:30
Vasanthdev2004	3eafaf584d	fix(tui): stop looping on repeated failure + clear loop tag on cancel Addresses CodeRabbit review on #502: - advanceLoop now counts consecutive failed iterations (loopMaxFailures=3) and stops the loop, so a loop whose turns keep erroring no longer churns to the iteration cap (the doom guard only sees identical non-empty answers). - cancelRun clears activeLoopID and re-arms the interrupted loop for its next cadence, so a cancelled iteration is not left running forever and the next unrelated turn is not misattributed as that loop's completion.	2026-07-06 08:53:04 +05:30
Vasanthdev2004	9cfdb2fecf	docs(readme): add /loop to the slash-command table	2026-07-06 08:53:04 +05:30
Vasanthdev2004	4ffbf4e0fe	test(tui): drive /loop end-to-end through Update (submit + stale tick)	2026-07-06 08:53:04 +05:30
Vasanthdev2004	440d4df367	feat(tui): /loop self-paced adaptive cadence + footer summary + /clear note Third slice of #501. - Self-paced loops now use an adaptive cadence (2m early -> 30m heartbeat as iterations accrue), with the loopNextWake channel kept as an override for a future explicit model signal. - Persistent footer segment "↻ N loops · next 3:05pm" while loops are active. - /clear notes that loops keep running (it wipes the transcript, not the session) so a loop never silently fires into a cleared screen. - Tests for adaptive cadence + footer summary.	2026-07-06 08:53:04 +05:30
Vasanthdev2004	4bc9a97176	feat(tui): wire /loop into the turn lifecycle — dispatch, idle tick, continuation Second slice of #501. Adds the controller and wires it in: - /loop command registered (commands.go) and dispatched to handleLoopCommand. - Loop state on the model (loops, activeLoopID, loopSeq/loopTicking poll guards, loopNextWake/loopDone self-pace channel). - An idle poll tick (loopTickMsg, ~1s) fires the earliest due loop only when the session is idle — mirrors the launchQueuedMessageIfReady guard so loops and a user's queued prompt never collide; a self-perpetuating tea.Tick that stops when no loops remain. - The agentResponseMsg completion seam advances a loop iteration (schedule next wake for fixed, model delay for self-paced) with doom-loop, iteration-cap, and done stop conditions, restarting the ticker if other loops remain. - /loop list\|stop\|stop all, footer summary + list rendering, and a guard that only a prompt or custom /command may loop (not a built-in). Controller tests cover start/advance/self-paced-delay/done/doom/cap/stop/busy.	2026-07-06 08:53:04 +05:30
Vasanthdev2004	6d7d3946c8	feat(tui): /loop foundation — command parsing, loop state, safety bounds First slice of the /loop feature (#501): the self-contained core with no TUI wiring yet. parseLoopCommand handles the leading-interval, trailing-"every", bare-self-paced, and list/stop forms; loopState models one session-scoped loop with doom-loop + iteration-cap fields; interval/self-pace clamps and duration formatting round it out, with unit tests. Because Zero drives loops off a Go timer rather than a cron backend, arbitrary intervals (90s, 7m) are supported with no whitelist limitation.	2026-07-06 08:52:13 +05:30
