# Dependency graph
requires:
  - phase: 05-multi-model-discussions/02
    provides: Orchestrator with query_models_parallel, /open command
  - phase: 04-single-model-qa/02
    provides: AIClient.complete() and typing indicator pattern
provides:
  - build_context() for assembling discussion history
  - run_discussion_round() for sequential model execution
  - /discuss command for starting multi-round discussions
  - /next command for round progression
  - /stop command for early termination
affects: [05-04-mentions, 06-consensus, 06-export]

key-decisions:
  - "Sequential execution uses for-loop (not asyncio.gather) so each model sees prior responses"
  - "Context stored in user_data['discussion_state'] for /next and /stop access"
  - "All prior responses formatted as user messages with **Model:** prefix for context"

patterns-established:
  - "run_discussion_round returns dict[str, str] and creates Round+Messages"
  - "Discussion state in user_data enables multi-command flows"

# Phase 5 Plan 3: Discuss Mode Summary

**Sequential multi-round discussion with /discuss, /next, /stop commands and full context building**

## Performance

- **Duration:** 5 min
- **Started:** 2026-01-16T19:40:00Z
- **Completed:** 2026-01-16T19:45:21Z
- **Tasks:** 3
- **Files modified:** 3

## Accomplishments

- Added build_context() to convert discussion history to OpenAI message format
- Added run_discussion_round() for sequential model execution with context accumulation
- Implemented /discuss [rounds] command with configurable round limit
- Implemented /next for round progression and /stop for early termination
- State stored in user_data for multi-command discussion flow

## Task Commits

Each task was committed atomically:

1. **Task 1: Add context building and sequential round execution** - `9133d4e` (feat)
2. **Task 2: Implement /discuss command handler** - `104eceb` (feat)
3. **Task 3: Implement /next and /stop commands** - `3ae08e9` (feat)

**Plan metadata:** (pending)

## Files Created/Modified

- `src/moai/core/orchestrator.py` - Added build_context() and run_discussion_round() functions
- `src/moai/bot/handlers/discussion.py` - Added discuss_command, next_command, stop_command handlers
- `src/moai/bot/handlers/__init__.py` - Registered /discuss, /next, /stop command handlers

## Decisions Made

- Sequential execution uses for-loop instead of asyncio.gather so each model sees responses from earlier models in the same round
- Context messages use user role with **Model:** prefix for AI context
- Discussion state stored in user_data["discussion_state"] for multi-command flow

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None

## Next Phase Readiness

- M5 milestone (Discuss mode sequential) complete
- Ready for 05-04-PLAN.md (@mention direct messages)
- Discussion infrastructure ready for consensus generation in Phase 6
