+# Phase 6 Plan 1: Consensus Generation Summary
+
+**AI-powered consensus generation via CONSENSUS_PROMPT constant, generate_consensus() orchestrator function, and /consensus command handler**
+
+## Performance
+
+- **Duration:** 5 min
+- **Started:** 2026-01-16T20:02:13Z
+- **Completed:** 2026-01-16T20:07:55Z
+- **Tasks:** 2
+- **Files modified:** 4
+
+## Accomplishments
+
+- Added CONSENSUS_PROMPT constant with JSON output instructions for agreements/disagreements
+- Implemented generate_consensus() function using existing build_context() and AI client
+- Created save_consensus() and get_consensus() service functions for persistence
+- Added /consensus command handler with Markdown formatting
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Add consensus generation to orchestrator and service** - `8242de5` (feat)
+2. **Task 2: Create /consensus command handler** - `ee9f8ca` (feat)
+
+## Files Created/Modified
+
+- `src/moai/core/orchestrator.py` - Added CONSENSUS_PROMPT, generate_consensus()
+- `src/moai/core/services/discussion.py` - Added save_consensus(), get_consensus()
+- `src/moai/bot/handlers/discussion.py` - Added consensus_command handler
+- `src/moai/bot/handlers/__init__.py` - Registered consensus CommandHandler
+
+## Decisions Made
+
+- JSON format for consensus output (agreements: string[], disagreements: [{topic, positions}])
+- Graceful error handling on JSON parse failure returns empty consensus
+- Check for existing consensus before generating new one
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None.
+
+## Next Phase Readiness
+
+- Consensus generation complete, ready for 06-02 (export functionality)
+- /consensus command fully functional for active discussions
