How do I implement type safety in an existing project?

This skill provides an incremental adoption strategy, focusing on annotating public signatures first and enabling strict mode on a per-module basis.

What are Protocols in this context?

Protocols allow for structural typing (static duck typing), letting you define interfaces based on object behavior and methods rather than strict class inheritance.

How does this skill improve Python code quality?

It implements static type checking patterns that catch errors before execution, serves as enforced documentation, and improves IDE autocompletion and developer experience.

Can I use this with older Python versions?

Yes, while it favors modern Python 3.10+ syntax like the pipe operator for unions, it provides patterns and aliases compatible with older versions using the typing module.

Does this require specific tools like mypy?

While it provides the logic and patterns, it is designed to be paired with static type checkers like mypy or pyright to validate the annotations automatically.

Implements robust static analysis and type hinting patterns to ensure Python code reliability and maintainability.

概要

Python Type Safety empowers developers to leverage modern Python's static typing ecosystem within Claude Code. By implementing comprehensive type hints, generics, and structural protocols, this skill helps catch logical errors during development rather than at runtime. It provides standardized patterns for type narrowing, generic repositories, and strict mypy/pyright configurations, transforming Python into a more predictable and self-documenting language for large-scale applications and professional libraries.
