# Hooks Validator

Validate hooks configuration in `.claude/settings.json` and hook scripts.

---

## Validation Steps

### 1. Check settings.json
Verify `hooks` section exists and is valid.

### 2. Validate Hook Structure
```json
{
  "hooks": {
    "PreToolUse": [...],
    "PostToolUse": [...],
    "UserPromptSubmit": [...],
    "Stop": [...],
    "SubagentStop": [...],
    "SessionStart": [...],
    "SessionEnd": [...],
    "PreCompact": [...],
    "PostCompact": [...],
    "Notification": [...],
    "Elicitation": [...],
    "ElicitationResult": [...]
  }
}
```

### 3. Validate Each Hook Entry
- [ ] `type` is "command" or "prompt"
- [ ] If `type: "command"`: `command` path exists and script is executable
- [ ] If `type: "prompt"`: `prompt` string is non-empty
- [ ] `timeout` is positive integer if present (default: 60s command, 30s prompt)
- [ ] `once` is boolean if present

### 4. Validate Hook Scripts
- [ ] File exists and is executable
- [ ] Outputs valid JSON
- [ ] Has appropriate shebang
