# Phase 5 Plan 4: @Mention Direct Messages Summary

**@claude/@gpt/@gemini direct message handlers with discussion context and enhanced /status display**

## Performance

- **Duration:** 8 min
- **Started:** 2026-01-16T19:50:00Z
- **Completed:** 2026-01-16T19:58:00Z
- **Tasks:** 3
- **Files modified:** 4

## Accomplishments

- Added query_model_direct() function for single model queries with optional discussion context
- Implemented @mention message handler with regex filter for @claude, @gpt, @gemini
- Direct messages persist with is_direct=True flag when discussion is active
- Enhanced /status command to show active discussion info (round progress, message count, discussion ID)

## Task Commits

Each task was committed atomically:

1. **Task 1: Add query_model_direct() to orchestrator** - `5934d21` (feat)
2. **Task 2: Implement @mention message handler** - `3296874` (feat)
3. **Task 3: Update /status to show active discussion info** - `2a86d39` (feat)

**Plan metadata:** (pending)

## Files Created/Modified

- `src/moai/core/orchestrator.py` - Added query_model_direct() function for direct model queries
- `src/moai/bot/handlers/discussion.py` - Added mention_handler for @model messages
- `src/moai/bot/handlers/__init__.py` - Registered MessageHandler with regex filter
- `src/moai/bot/handlers/status.py` - Enhanced to show project and discussion state

## Decisions Made

- Direct messages prefix user input with "[Direct to you]:" so model knows it's specifically addressed
- MessageHandler registered after CommandHandlers to ensure commands take priority
- Regex filter `^@(claude|gpt|gemini)\s` requires space after model name

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None

## Next Phase Readiness

- M8 milestone (@mention direct messages) complete
- Phase 5 complete (M4, M5, M8 all done)
- Discussion infrastructure ready for consensus generation (Phase 6)
- Message context and is_direct flag available for export filtering
