What problem does it solve?

This Skill addresses the challenge of inconsistent Python typing and hidden type errors by providing a structured approach to typing using the standard typing module, Pydantic models for validation, and mypy-based checks to catch errors early.

Core Features & Use Cases

• Typing module usage: Use the Python typing module to annotate functions and data structures for clearer intent and safer code.
• Pydantic model design: Design and validate data structures with Pydantic models to ensure data integrity.
• Mypy configuration & usage: Configure and run mypy to catch type issues before runtime.
• Type aliases & generics: Create clear type aliases and generic abstractions to improve reusability.
• Use Case: Refactor a module to adopt consistent typing, migrate to Pydantic for input data, and validate with mypy across the project.

Quick Start

1. Install required packages: pip install mypy pydantic typing-extensions
2. Annotate code with typing, create Pydantic models, and configure mypy
3. Run mypy to perform static checks and fix type errors
