commit-message
Use whenever a Conventional Commit message is being drafted — whether the user asks ("write commit message", "draft commit from staged changes", "generate conventional commit", "message for git commit -F -") or you are about to propose one proactively after finishing work (e.g. completing tasks, wrapping up a feature, or summarizing staged changes). Invoke before writing the message inline. Not for creating commits, amending history, or full code review.
