lint

The `lint` skill provides an integrated framework for validating, formatting, and ensuring the quality of code before committing changes. It addresses common problems in software development such as inconsistent code style, type errors, security vulnerabilities, and documentation issues. By offering targeted linting and formatting capabilities, it enables developers to maintain high-quality code standards across a codebase, reducing the likelihood of bugs, runtime errors, and style inconsistencies that can arise when multiple contributors work on the same project.

This skill includes a comprehensive set of features for code quality assurance. It supports formatting code using Ruff, validating style compliance, performing type checks with mypy, and auditing code for security issues with Bandit. Users can run full checks across the codebase or target specific files or directories for more efficient validation. Additional capabilities include formatting snapshot test files, checking spelling and documentation, and verifying test infrastructure. The skill emphasizes automated fixes for style issues and selective type checking after adding type annotations, making it a versatile tool for maintaining consistent coding practices.

The `lint` skill is ideal for developers who want to ensure their code meets project standards before committing or pushing changes. Typical use cases include formatting newly edited files, validating code style and type hints, auditing security-sensitive code, and checking documentation or test artifacts. It is particularly useful in collaborative environments where multiple contributors must adhere to consistent style and quality guidelines, as well as in projects where automated checks are part of the continuous integration workflow. Target users include Python developers, quality assurance engineers, and teams aiming to streamline code review and enforce project-wide coding standards.
