pre-commit

Pre-commit checks validate your code before commits by running build, lint, and test commands. Execute pnpm build, pnpm lint, and pnpm test to enforce code quality, catch errors early, and prevent broken code from entering the repository.

Pre-commit enforces multiple hygiene rules: prohibits console.log except in CLI apps, disallows commented-out code and unreferenced TODOs, requires Effect-TS patterns and proper error handling, ensures barrel exports are updated, and mandates CLAUDE.md updates for new patterns.

Yes, run pnpm lint --fix to automatically fix linting violations and sort imports and objects. This auto-correction streamlines the pre-commit workflow by resolving common issues without manual intervention.

Pre-commit integrates with TypeScript type checking and ESLint linting as part of its hygiene validation pipeline. It runs type checks and lint rules alongside build and test commands to ensure code quality across your PNPM-based project.

Follow the manual pre-commit checklist: verify builds pass, linting passes, tests pass, console.log is removed except in CLI apps, commented code and TODOs without issues are removed, and barrel exports and CLAUDE.md are updated if patterns changed.

Pre-commit validation is essential before pushing code to prevent hygiene violations from entering the codebase. It catches type errors, lint violations, test failures, and convention breaches early, reducing code review friction and maintaining consistent code quality.
