+# Phase 3 Plan 3: Project Models & Delete Summary
+
+**Full Project CRUD complete: /project models configures AI model list, /project delete removes projects with cascade - M2 milestone done**
+
+## Performance
+
+- **Duration:** 5 min
+- **Started:** 2026-01-16T18:50:00Z
+- **Completed:** 2026-01-16T18:55:00Z
+- **Tasks:** 2
+- **Files modified:** 2
+
+## Accomplishments
+- Added update_project_models(project_id, models) to service layer
+- Added delete_project(project_id) with cascade handling
+- Implemented /project models command (show/set AI models for current project)
+- Implemented /project delete command requiring explicit ID for safety
+- Completed M2 milestone: full project CRUD via Telegram
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Add update_models and delete_project to service** - `e2e10d9` (feat)
+2. **Task 2: Implement /project models and /project delete handlers** - `bb3eab7` (feat)
+
+**Plan metadata:** `afab4f8` (docs: complete plan)
+
+## Files Created/Modified
+- `src/moai/core/services/project.py` - Added update_project_models and delete_project functions
+- `src/moai/bot/handlers/projects.py` - Added models/delete handlers, updated usage help
+
+## Decisions Made
+- Require explicit project ID for delete (not name) for safety
+- Comma-separated model list parsing (e.g., "claude,gpt,gemini")
+- Clear user_data selection when deleting the currently selected project
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+None
+
+## Next Phase Readiness
+- M2 milestone complete
+- Full project CRUD available: new, select, info, models, delete
+- Ready for Phase 4: Single Model Q&A
