+### Matchers and tool names
+
+For `BeforeTool` and `AfterTool` events, the `matcher` field in your settings is
+compared against the name of the tool being executed.
+
+- **Built-in Tools**: You can match any built-in tool (e.g., `read_file`,
+  `run_shell_command`). See the [Tools Reference](/docs/tools) for a full list
+  of available tool names.
+- **MCP Tools**: Tools from MCP servers follow the naming pattern
+  `mcp__<server_name>__<tool_name>`.
+- **Regex Support**: Matchers support regular expressions (e.g.,
+  `matcher: "read_.*"` matches all file reading tools).
+
+### `BeforeTool`
+
+Fires before a tool is invoked. Used for argument validation, security checks,
+and parameter rewriting.
+
+- **Input Fields**:
+  - `tool_name`: (`string`) The name of the tool being called.
+  - `tool_input`: (`object`) The raw arguments generated by the model.
+  - `mcp_context`: (`object`) Optional metadata for MCP-based tools.
+- **Relevant Output Fields**:
+  - `decision`: Set to `"deny"` (or `"block"`) to prevent the tool from
+    executing.
+  - `reason`: Required if denied. This text is sent **to the agent** as a tool
+    error, allowing it to respond or retry.
+  - `hookSpecificOutput.tool_input`: An object that **merges with and
+    overrides** the model's arguments before execution.
+  - `continue`: Set to `false` to **kill the entire agent loop** immediately.
+- **Exit Code 2 (Block Tool)**: Prevents execution. Uses `stderr` as the
+  `reason` sent to the agent. **The turn continues.**
+
+### `AfterTool`
+
+Fires after a tool executes. Used for result auditing, context injection, or
+hiding sensitive output from the agent.
+
+- **Input Fields**:
+  - `tool_name`: (`string`)
+  - `tool_input`: (`object`) The original arguments.
+  - `tool_response`: (`object`) The result containing `llmContent`,
+    `returnDisplay`, and optional `error`.
+  - `mcp_context`: (`object`)
+- **Relevant Output Fields**:
+  - `decision`: Set to `"deny"` to hide the real tool output from the agent.
+  - `reason`: Required if denied. This text **replaces** the tool result sent
+    back to the model.
+  - `hookSpecificOutput.additionalContext`: Text that is **appended** to the
+    tool result for the agent.
+  - `continue`: Set to `false` to **kill the entire agent loop** immediately.
+- **Exit Code 2 (Block Result)**: Hides the tool result. Uses `stderr` as the
+  replacement content sent to the agent. **The turn continues.**
+
+---
+
+## Agent hooks
+
+### `BeforeAgent`
+
+Fires after a user submits a prompt, but before the agent begins planning. Used
+for prompt validation or injecting dynamic context.
+
+- **Input Fields**:
+  - `prompt`: (`string`) The original text submitted by the user.
+- **Relevant Output Fields**:
+  - `hookSpecificOutput.additionalContext`: Text that is **appended** to the
+    prompt for this turn only.
+  - `decision`: Set to `"deny"` to block the turn and **discard the user's
+    message** (it will not appear in history).
+  - `continue`: Set to `false` to block the turn but **save the message to
+    history**.
+  - `reason`: Required if denied or stopped.
+- **Exit Code 2 (Block Turn)**: Aborts the turn and erases the prompt from
+  context. Same as `decision: "deny"`.
+
+### `AfterAgent`
+
+Fires once per turn after the model generates its final response. Primary use
+case is response validation and automatic retries.
+
+- **Input Fields**:
+  - `prompt`: (`string`) The user's original request.
+  - `prompt_response`: (`string`) The final text generated by the agent.
+  - `stop_hook_active`: (`boolean`) Indicates if this hook is already running as
+    part of a retry sequence.
+- **Relevant Output Fields**:
+  - `decision`: Set to `"deny"` to **reject the response** and force a retry.
+  - `reason`: Required if denied. This text is sent **to the agent as a new
+    prompt** to request a correction.
+  - `continue`: Set to `false` to **stop the session** without retrying.
+  - `clearContext`: If `true`, clears conversation history (LLM memory) while
+    preserving UI display.
+- **Exit Code 2 (Retry)**: Rejects the response and triggers an automatic retry
+  turn using `stderr` as the feedback prompt.
+
+---
+
+## Model hooks
+
+### `BeforeModel`
+
+Fires before sending a request to the LLM. Operates on a stable, SDK-agnostic
+request format.
+
+- **Input Fields**:
+  - `llm_request`: (`object`) Contains `model`, `messages`, and `config`
+    (generation params).
+- **Relevant Output Fields**:
+  - `hookSpecificOutput.llm_request`: An object that **overrides** parts of the
+    outgoing request (e.g., changing models or temperature).
+  - `hookSpecificOutput.llm_response`: A **Synthetic Response** object. If
+    provided, the CLI skips the LLM call entirely and uses this as the response.
+  - `decision`: Set to `"deny"` to block the request and abort the turn.
+- **Exit Code 2 (Block Turn)**: Aborts the turn and skips the LLM call. Uses
+  `stderr` as the error message.
+
+### `BeforeToolSelection`
+
+Fires before the LLM decides which tools to call. Used to filter the available
+toolset or force specific tool modes.
+
+- **Input Fields**:
+  - `llm_request`: (`object`) Same format as `BeforeModel`.
+- **Relevant Output Fields**:
+  - `hookSpecificOutput.toolConfig.mode`: (`"AUTO" | "ANY" | "NONE"`)
+    - `"NONE"`: Disables all tools (Wins over other hooks).
+    - `"ANY"`: Forces at least one tool call.
+  - `hookSpecificOutput.toolConfig.allowedFunctionNames`: (`string[]`) Whitelist
+    of tool names.
+- **Union Strategy**: Multiple hooks' whitelists are **combined**.
+- **Limitations**: Does **not** support `decision`, `continue`, or
+  `systemMessage`.
+
+### `AfterModel`
+
+Fires immediately after an LLM response chunk is received. Used for real-time
+redaction or PII filtering.
+
+- **Input Fields**:
+  - `llm_request`: (`object`) The original request.
+  - `llm_response`: (`object`) The model's response (or a single chunk during
+    streaming).
+- **Relevant Output Fields**:
+  - `hookSpecificOutput.llm_response`: An object that **replaces** the model's
+    response chunk.
+  - `decision`: Set to `"deny"` to discard the response chunk and block the
+    turn.
+  - `continue`: Set to `false` to **kill the entire agent loop** immediately.
+- **Note on Streaming**: Fired for **every chunk** generated by the model.
+  Modifying the response only affects the current chunk.
+- **Exit Code 2 (Block Response)**: Aborts the turn and discards the model's
+  output. Uses `stderr` as the error message.
+
+---
+
+## Lifecycle & system hooks
+
+### `SessionStart`
+
+Fires on application startup, resuming a session, or after a `/clear` command.
+Used for loading initial context.
+
+- **Input fields**:
+  - `source`: (`"startup" | "resume" | "clear"`)
+- **Relevant output fields**:
+  - `hookSpecificOutput.additionalContext`: (`string`)
+    - **Interactive**: Injected as the first turn in history.
+    - **Non-interactive**: Prepended to the user's prompt.
+  - `systemMessage`: Shown at the start of the session.
+- **Advisory only**: `continue` and `decision` fields are **ignored**. Startup
+  is never blocked.
+
+### `SessionEnd`
+
+Fires when the CLI exits or a session is cleared. Used for cleanup or final
+telemetry.
+
+- **Input Fields**:
+  - `reason`: (`"exit" | "clear" | "logout" | "prompt_input_exit" | "other"`)
+- **Relevant Output Fields**:
+  - `systemMessage`: Displayed to the user during shutdown.
+- **Best Effort**: The CLI **will not wait** for this hook to complete and
+  ignores all flow-control fields (`continue`, `decision`).
+
+### `Notification`
+
+Fires when the CLI emits a system alert (e.g., Tool Permissions). Used for
+external logging or cross-platform alerts.
+
+- **Input Fields**:
+  - `notification_type`: (`"ToolPermission"`)
+  - `message`: Summary of the alert.
+  - `details`: JSON object with alert-specific metadata (e.g., tool name, file
+    path).
+- **Relevant Output Fields**:
+  - `systemMessage`: Displayed alongside the system alert.
+- **Observability Only**: This hook **cannot** block alerts or grant permissions
+  automatically. Flow-control fields are ignored.
+
+### `PreCompress`
+
+Fires before the CLI summarizes history to save tokens. Used for logging or
+state saving.
+
+- **Input Fields**:
+  - `trigger`: (`"auto" | "manual"`)
+- **Relevant Output Fields**:
+  - `systemMessage`: Displayed to the user before compression.
+- **Advisory Only**: Fired asynchronously. It **cannot** block or modify the
+  compression process. Flow-control fields are ignored.
