preflight-checks

To run linters and type checkers on staged files, this Skill scopes checks to modified files and auto-detects tools like ESLint, mypy, and Ruff from project configs. It executes the relevant checks and attempts to auto-fix common formatting and linting errors.

Automatically formatting code and fixing linting errors before a pull request is handled by the auto-fix protocol. It runs detected formatters like Prettier, applies fixes to simple issues, and re-stages the modified files so they are ready for commit.

Yes, this pre-commit code quality check supports Python projects by auto-detecting Ruff and mypy from configuration files like pyproject.toml. It runs these tools on your staged or modified Python files to ensure quality and consistency.

You can use this tool to check TypeScript types and lint JavaScript by auto-detecting ESLint and TypeScript configurations from package.json. It executes these checkers on your changed files to prevent type and lint issues from being committed.

Automated pre-commit tool detection for mixed-language projects works by reading configuration files like package.json and pyproject.toml. It intelligently identifies and runs the relevant linters, formatters, and type checkers for each staged file's respective language.

Scoping pre-commit linting to modified files instead of the whole project optimizes performance by only running checks on changed code. This ensures fast feedback and targeted auto-fixing before commits without processing unaffected files.
