Implementation is complete, well-tested, and production-ready.

## Implementation Complete **Problem:** Hook manager service needed CRUD operations for managing hooks in Claude Code settings files. **Changes Made:** 1. **HookManager service** (`services/hook_manager.py`): - `get_hooks(source)` - Read hooks from specific settings source - `get_hooks_for_event(event_type, source)` - Read hooks for specific event - `add_hook(event_type, matcher, hook, source)` - Add single hook to matcher - `add_hook_matcher(event_type, matcher_data, source)` - Add complete matcher - `update_hook(event_type, matcher, hook_index, hook, source)` - Update specific hook - `remove_hook(event_type, matcher, hook_index, source)` - Remove hook by index or all - `remove_hooks_for_event(event_type, source)` - Clear all hooks for event - `clear_hooks(source)` - Remove all hooks from source - Full validation using Pydantic models - Preserves other settings when writing 2. **API Endpoints** (`routers/config.py`): - `GET /config/hooks/{source}` - Get hooks from specific source - `GET /config/hooks/{source}/{event_type}` - Get hooks for event - `POST /config/hooks/add` - Add a hook - `POST /config/hooks/add-matcher` - Add complete matcher - `PUT /config/hooks/update` - Update a hook - `DELETE /config/hooks/remove` - Remove hook(s) - `DELETE /config/hooks/{source}/{event_type}` - Clear event hooks - `DELETE /config/hooks/clear` - Clear all hooks 3. **Tests** (`tests/unit/test_hook_manager.py`): - 35 comprehensive unit tests covering all operations - All tests passing **Verification:** ``` pytest tests/unit/test_hook_manager.py tests/unit/test_config_reader.py -v ============================== 65 passed ============================== ``` **QA Criteria Status:** - [x] Can read existing hooks from settings - [x] Can add new hook configuration - [x] Can remove hook by event - [x] Validates hook structure - [x] Preserves other settings when writing

## Feature Triage Complete **Status:** PARTIALLY IMPLEMENTED **Summary:** The `hook_manager.py` file exists but is essentially empty (just a docstring). READ operations for hooks are already fully implemented in ConfigReader and exposed via GET `/config/hooks`. What's missing is the WRITE side: Create, Update, Delete operations. **Current Implementation:** - ConfigReader already handles reading and merging hooks from all settings sources - HooksConfig and related models are fully defined in models/config.py - GET /config/hooks endpoint is functional **What Needs Implementation:** - HookManager service with add_hook(), remove_hook(), update_hook() methods - Read-modify-write pattern for settings files (preserving other settings) - Hook structure validation using existing Pydantic models - New API endpoints for CRUD operations **Implementation Location:** - Primary: `src/cli_agent_api/services/hook_manager.py` - Endpoints: New router or extend `routers/config.py` - Tests: `tests/unit/test_hook_manager.py` **Complexity:** Medium (~300-400 lines service + endpoints, ~200-300 lines tests) **Dependencies:** CLIAPI-22 (ConfigReader) - already completed See attached triage report at /tmp/triage-CLIAPI-24.md for full details.
