# Core Development Principles
principles:
  - name: 'Python Modernization'
    description: 'Use modern Python features and maintain compatibility with 3.13+'
    rules:
      - 'All projects must use Python 3.13 or newer'
      - 'Use type hints throughout all code'
      - 'Prefer dataclasses over traditional classes for data structures'
      - 'Use pathlib for all file path operations'

  - name: 'Virtual Environment Isolation'
    description: 'Maintain clean, reproducible development environments'
    rules:
      - 'All projects must use Python virtual environments'
      - 'Virtual environments must be named `.venv` in project root'
      - 'Dependencies must be pinned in requirements.txt'
      - 'Development dependencies must be separate from production'

  - name: 'Test-Driven Development'
    description: 'Write tests first, maintain high test coverage'
    rules:
      - 'All new features must include tests before implementation'
      - 'Test coverage must be maintained at 80% minimum'
      - 'Use pytest as the primary testing framework'
      - 'Unit tests, integration tests, and API tests must be separated'

  - name: 'Containerization Standards'
    description: 'Consistent container deployment across all services'
    rules:
      - 'Use Docker Compose V3 syntax exclusively'
      - 'Command must be `docker compose` not `docker-compose`'
      - 'Multi-stage builds for production containers'
      - 'Health checks in all service definitions'
