**commit‑msg‑checker** is a Node‑based tool that validates Git commit messages against a conventional format (`<type>(<scope>): <subject>`), enforcing types like `feat`, `fix`, `docs`, etc. It’s intended for developers who want to ensure consistent, readable commit logs in JavaScript/Node projects, and can be installed as a dev dependency and enabled via a simple `checker-init` command or custom settings in `package.json`.
