Lint And Validate

Enforces a strict validation loop after every code change across Node.js, TypeScript, and Python projects. Runs ESLint, TypeScript compiler checks, npm audit for JavaScript, and Ruff, Bandit, and MyPy for Python. The mandatory framing is intentional: it won't let you mark work complete until linting and type checks pass. Useful if you want Claude to catch style issues and type errors before you do, though the rigid "must pass before done" rule might feel heavy handed on exploratory work or when dealing with legacy codebases that have existing violations. Best for greenfield projects or teams that want automated quality gates baked into the workflow.

Lint and Validate

When to Use

Use after behavior or configuration changes when a repository has relevant lint or type checks. Read the repository's instructions and package scripts first. Run focused checks during development and the required checks before completion.
