Does it support type narrowing?

Absolutely. The skill covers TypeGuards, Literals, and standard narrowing techniques like isinstance and None checks.

What Python versions does this skill support?

The patterns focus on Python 3.10 and 3.11+, utilizing modern features like the pipe (|) union operator, Self, and TypeVarTuple.

Can it help with JSON-like data structures?

Yes, it includes patterns for TypedDict, which allows you to define the specific keys and value types for dictionary objects.

How does this handle structural typing?

It provides specific patterns for using the Protocol class from the typing module to implement static duck typing.

Does this work with mypy and pyright?

Yes, all patterns are designed to be compatible with major static type checkers, and it includes configuration templates for both mypy and pyright.

개발자 도구

Implements modern Python type hints and safety patterns to ensure robust, self-documenting codebases.

소개

This skill equips Claude with specialized knowledge for implementing advanced type systems in Python 3.10+ environments. It provides comprehensive guidance on modern syntax, including Union types (X | Y), structural typing via Protocols, and Generic type variables. By following these patterns, developers can leverage static analysis tools like mypy and pyright more effectively, catching bugs early and improving IDE autocompletion and code maintainability across complex projects.
