Python Engineering Skill Policy

Code is Mechanism, Prompt is Policy

Python Standards (v2.0 - Modern)

When writing or editing Python code:

1. State Management - Use StrEnum instead of magic strings
2. Control Flow - Prefer match/case over complex if/elif chains
3. Type Safety - Use @override for inherited methods and new generic syntax class Foo[T]
4. Concurrency - Use asyncio.TaskGroup instead of gather
5. Legacy Standards - Follow PEP 8, 4 spaces, and Google style docstrings

See lang-python-modern.md for complete standards.

Tools Available

• lint_python_style - Check code with ruff/flake8 (Configured for py313)
• run_pytest - Execute test suite
• check_types - Run pyright type checking
• format_python - Format code with ruff/black
