Commit Skill

Generate a 1-line commit message for current changes.

Steps

1. Run jj diff --git --no-pager to inspect the working-copy changes.
2. If there are no changes, say No changes in working copy. and stop.
3. Draft a short 1-line message that explicitly describes the changes. Use no conventional-commit prefix and no verbose description.
4. Return only the commit message. Do not run any source-control mutation commands.

Examples:

• fix token expiry edge case
• refactor auth middleware

Rules

• NEVER run jj commit, jj describe, jj new, or any jj mutation commands
• NEVER run git add, git commit, git push
• NEVER create branches or bookmarks
• Only return the message — the user will commit/describe themselves
