SKILL.md

This skill provides comprehensive guidance on Python type hints and static type checking for Python 3.9+ codebases. It serves as a reference during code reviews to ensure proper type annotation usage, evaluate type hint quality, and promote best practices for gradual typing adoption.

Type hints (introduced in PEP 484) enable static type checking in Python while maintaining the language's dynamic nature. Modern Python (3.9+) has significantly improved type hint syntax with built-in generic types and the union operator. Proper type hints improve:

Comprehensive reference guide for Python type hints, static type checking with mypy, modern type annotation patterns (PEP 484, 585, 604, 612, 613), and type hint best practices for Python 3.9+. Use during code reviews to ensure proper type annotation usage, evaluate mypy configuration, and identify type hint anti-patterns. Source: clostaunau/holiday-card.
