Checkpoint commit

Checkpoint Commit

Use this skill when you want a real commit, not an autosave fallback.

Required Workflow

1. Confirm the current directory is inside a git repository.
2. Inspect git status --short.
3. If staged changes already exist, use them as the commit boundary.
4. If nothing is staged but the working tree is dirty, stage the current work with git add -A because the user explicitly invoked a commit checkpoint.
5. If there are still no changes, stop and report that there is nothing to commit.
6. Gather commit context from the staged diff:
   • git diff --cached --name-status
   • git diff --cached --stat
   • git diff --cached --unified=2
   • git log --oneline -5
7. Write the commit message from the actual diff.
8. Create the commit immediately unless the user explicitly asked for a preview only.

Commit Message Rules

• Follow Conventional Commits.
• Choose feat, fix, docs, refactor, test, chore, perf, or ci based on the behavioral change shown in the diff, not only file names.
• Add a scope only when it is obvious and materially helpful.
• Keep the subject line concise, imperative, and specific.
• Use the user's $ARGUMENTS as optional intent if it improves the message.
• Add a body only when the diff spans multiple tightly related changes and the extra context is genuinely useful.
• Do not use timestamps.
• Do not use placeholder phrases like update files or misc changes.
• Do not expose hidden reasoning or chain-of-thought.

Guardrails

• Prefer one logical commit. If the staged diff spans unrelated concerns, stop and tell the user to split the change set.
• Do not push.
• Do not amend unless the user explicitly asks.
• If git commit fails, report the failure and the proposed commit message clearly.

Output

After committing, report:

1. The final commit subject.
2. Whether a commit body was used.
3. The files included in the staged set.
