# Phase 3 Plan 1: Project Service & List/Create Summary

**Project service layer with list/create functions and /projects, /project new Telegram commands**

## Performance

- **Duration:** 3 min
- **Started:** 2026-01-16T18:40:00Z
- **Completed:** 2026-01-16T18:43:00Z
- **Tasks:** 2
- **Files modified:** 4

## Accomplishments

- Created services package with project service module
- Implemented list_projects(), create_project(), get_project() functions
- Added /projects command to list all projects with details
- Added /project new "Name" command to create projects

## Task Commits

Each task was committed atomically:

1. **Task 1: Create project service module** - `718dcea` (feat)
2. **Task 2: Implement /projects and /project new handlers** - `3f3b5ce` (feat)

## Files Created/Modified

- `src/moai/core/services/__init__.py` - Service package init, exports
- `src/moai/core/services/project.py` - list_projects, create_project, get_project
- `src/moai/bot/handlers/projects.py` - projects_command, project_command handlers
- `src/moai/bot/handlers/__init__.py` - Register project handlers

## Decisions Made

- Used service layer pattern to keep handlers thin
- Single project_command handler parses subcommands (new/select/delete/models/info)
- Default models list: ["claude", "gpt", "gemini"]

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None

## Next Phase Readiness

- Project service ready for additional operations (select, delete, models, info)
- Handler structure supports adding more subcommands
- Ready for 03-02-PLAN.md (project select/delete)
