How does this skill assist with mypy configuration?

It provides a standardized, 'strict' pyproject.toml configuration that enables rigorous checks like disallowing untyped definitions and redundant casts.

What is the benefit of using Protocol over standard inheritance?

Protocols enable structural subtyping, allowing Claude to define interfaces that classes can satisfy without explicit inheritance, promoting more flexible code.

Does this skill support Python versions older than 3.13?

Yes, while it prioritizes Python 3.13 features like the 'type' statement, it includes compatible patterns for versions 3.9+ such as TypeAlias and built-in generics.

Can this skill help reduce the use of 'Any' in my code?

Absolutely. It provides strategies for using 'object', generics, and TypedDict to replace 'Any' with more precise, type-safe alternatives.

Herramientas para Desarrolladores

Enforces strict Python 3.13 type hinting and mypy configurations to ensure production-grade code quality and static type safety.

Acerca de

This skill provides comprehensive guidance for implementing advanced Python typing patterns and maintaining zero-error mypy strict mode compliance. It covers modern Python 3.13 features including the new 'type' statement, PEP 604 union operators, and structural typing via Protocols. It is essential for developers who want to eliminate runtime TypeErrors, improve IDE autocompletion, and establish robust CI/CD type-checking gates for high-stakes Python applications.
