# 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

## 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
