# Phase 04-02: /ask Command Handler Summary

**Single model Q&A via /ask command, completing M3 milestone and Phase 4**

## Performance

- **Duration:** 5 min
- **Started:** 2026-01-16T19:10:00Z
- **Completed:** 2026-01-16T19:15:00Z
- **Tasks:** 3
- **Files modified:** 5

## Accomplishments
- Integrated AI client initialization into bot lifecycle (post_init)
- Created /ask handler with model validation and usage help
- Added "Questions" section to help text with /ask command
- Updated /status to show AI router configuration

## Task Commits

Each task was committed atomically:

1. **Task 1: Integrate AI client into bot lifecycle** - `821b419` (feat)
2. **Task 2: Create /ask handler for single model queries** - `32983c9` (feat)
3. **Task 3: Update help text and status** - `7078379` (feat)

**Plan metadata:** (this commit) (docs)

## Files Created/Modified
- `src/moai/bot/handlers/discussion.py` - ask_command handler (new)
- `src/moai/bot/main.py` - AI client initialization in post_init
- `src/moai/bot/handlers/__init__.py` - Register /ask handler
- `src/moai/bot/handlers/commands.py` - Questions section in HELP_TEXT
- `src/moai/bot/handlers/status.py` - AI router status display

## Decisions Made
- AI client initialized alongside database in post_init (consistent pattern)
- Typing indicator sent while waiting for AI response (UX feedback)
- Project context optionally included if a project is selected

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None.

## Milestone Completion

**M3 Milestone: Single Model Q&A - COMPLETE**

Users can now:
- Query individual AI models via `/ask <model> <question>`
- See available models (claude, gpt, gemini) in usage help
- View AI router status via `/status`

## Phase 4 Completion

**Phase 4: Single Model Q&A - COMPLETE**

Both plans completed:
- 04-01: AI client abstraction (AIClient, MODEL_MAP, config)
- 04-02: /ask command handler (this plan)

Note: Original roadmap estimated 3 plans (including 04-03 error handling), but core functionality is complete. Error handling can be enhanced in future phases if needed.
