+Runs when session ends to perform cleanup or final logging. Cannot block termination.

+- `clear` - User cleared the session
+- `logout` - User logged out
+- `prompt_input_exit` - User exited via prompt input
+- `other` - Other reason

+## Component-Scoped Hooks
+
+Hooks can be attached to specific components (skills, agents, commands) in their frontmatter:
+
+**In SKILL.md, agent.md, or command.md:**
+
+```yaml
+---
+name: secure-operations
+description: Perform operations with security checks
+hooks:
+  PreToolUse:
+    - matcher: "Bash"
+      hooks:
+        - type: command
+          command: "./scripts/check.sh"
+          once: true  # Only run once per session
+---
+```
+
+**Supported events for component hooks:** `PreToolUse`, `PostToolUse`, `Stop`
+
+This allows defining hooks directly in the component that uses them, keeping related code together.
+
+## PermissionRequest Event
+
+Handles permission requests with custom output format:
+
+```json
+{
+  "hookSpecificOutput": {
+    "hookEventName": "PermissionRequest",
+    "decision": {
+      "behavior": "allow|deny",
+      "updatedInput": {},
+      "message": "Custom message",
+      "interrupt": false

+## Plugin Hooks
+
+Plugins can include hooks in their `hooks/hooks.json` file:
+
+**File:** `plugins/hooks/hooks.json`
+
+```json
+{
+  "hooks": {
+    "PreToolUse": [
+      {

+  }
+}

+
+**Environment Variables in Plugin Hooks:**
+- `${CLAUDE_PLUGIN_ROOT}` - Path to the plugin directory
+
+This allows plugins to include custom validation and automation hooks.
