commitlint is a linter that validates commit messages against rules, typically a conventional commit format, and fails when a message does not conform. It runs as a hook locally or as a check in CI. It enforces the structured commit messages that automated versioning and changelogs depend on.
Why it matters
Release automation that reads commit messages only works if those messages follow the convention. commitlint enforces that at commit time, so the history stays parseable. Running it both as a local hook and a CI check catches violations before they reach the main branch.
