概要
This skill acts as an automated guide for maintaining high-quality Python code within the GMailArchiver repository. It ensures consistency across the codebase by enforcing strict type hints, standardized import ordering, and formatting rules as defined in the project's authoritative documentation. It is particularly useful for developers looking to fix linting errors, resolve Mypy type-checking issues, or verify that new contributions align with the project's Python 3.14+ requirements and 100-character line length limit.
