-
-## Development Commands
-
-### Backend (API)
-
-All Python commands must be prefixed with `uv run --project api`:
-
-```bash
-# Start development servers
-./dev/start-api                   # Start API server
-./dev/start-worker                # Start Celery worker
-
-# Run tests
-uv run --project api pytest      # Run all tests
-uv run --project api pytest tests/unit_tests/     # Unit tests only
-uv run --project api pytest tests/integration_tests/  # Integration tests
-
-# Code quality
-./dev/reformat                    # Run all formatters and linters
-uv run --project api ruff check --fix ./    # Fix linting issues
-uv run --project api ruff format ./         # Format code
-uv run --directory api basedpyright         # Type checking
-```
-
-### Frontend (Web)
-
-```bash
-cd web
-pnpm lint                         # Run ESLint
-pnpm eslint-fix                   # Fix ESLint issues
-pnpm test                         # Run Jest tests
-```
-
-## Testing Guidelines
-
-### Backend Testing
-
-- Use `pytest` for all backend tests
-- Write tests first (TDD approach)
-- Test structure: Arrange-Act-Assert
-
-## Code Style Requirements
-
-### Python
-
-- Use type hints for all functions and class attributes
-- No `Any` types unless absolutely necessary
-- Implement special methods (`__repr__`, `__str__`) appropriately
-
-### TypeScript/JavaScript
-
-- Strict TypeScript configuration
-- ESLint with Prettier integration
-- Avoid `any` type
-
-## Important Notes
-
-- **Environment Variables**: Always use UV for Python commands: `uv run --project api <command>`
-- **Comments**: Only write meaningful comments that explain "why", not "what"
-- **File Creation**: Always prefer editing existing files over creating new ones
-- **Documentation**: Don't create documentation files unless explicitly requested
-- **Code Quality**: Always run `./dev/reformat` before committing backend changes
-
-## Common Development Tasks
-
-### Adding a New API Endpoint
-
-1. Create controller in `/api/controllers/`
-1. Add service logic in `/api/services/`
-1. Update routes in controller's `__init__.py`
-1. Write tests in `/api/tests/`
-
-## Project-Specific Conventions
-
-- All async tasks use Celery with Redis as broker
-- **Internationalization**: Frontend supports multiple languages with English (`web/i18n/en-US/`) as the source. All user-facing text must use i18n keys, no hardcoded strings. Edit corresponding module files in `en-US/` directory for translations.
