## Current State
- **Phase:** DEVELOPMENT
- **Current Task:** task-012 (Implement AddTodo form)
- **Agent:** agent-frontend-001

## Progress Today
- [x] Bootstrap complete
- [x] Discovery complete
- [x] Architecture complete - OpenAPI spec created
- [x] Database schema implemented
- [x] Backend API endpoints (GET, POST, PUT)
- [ ] Frontend components (in progress)
- [ ] DELETE endpoint
- [ ] Integration tests

## Decisions Made
- Using SQLite for simplicity (per PRD)
- React Query for data fetching
- TailwindCSS for styling

## Mistakes & Learnings
- Initially forgot return type on Express handler
  - Fix: Always add `: void` to handlers
- First test run failed due to missing dev dependency
  - Fix: Check package.json before running tests

## Next Steps
1. Complete AddTodo form component
2. Implement TodoList component
3. Add DELETE endpoint
4. Run full test suite
