Git Commit Skill

Sensitive File Guard

Before staging, scan git status for sensitive patterns:

• .env*, *.pem, *.key, *.p12, *.pfx
• *.tfstate, *.tfvars (with real values)
• credentials.json, serviceAccountKey.json, *secret*

If a match is found:

1. Append the missing pattern to .gitignore and stage .gitignore.
2. If already tracked, warn and suggest git rm --cached <file>.
3. Never proceed with committing a sensitive file.

Smart Commit Workflow

1. Review & Sensitive File Guard

git status
git diff
git diff --cached
git log --oneline -5

Scan the output against the sensitive patterns above.

2. Auto-stage tracked changes

git add -u

Stage tracked modifications and deletions only. Review untracked files first and stage by name if appropriate.

3. Analyse for multi-concern splitting

Group changed files by directory or feature area. If changes span unrelated concerns (e.g. a bug fix and a new feature), split into separate commits automatically.

4. Generate commit message

• Infer type: feat, fix, chore, docs, refactor, test, style.
• Infer scope from the primary directory or feature area.
• Subject line: imperative voice, under 72 characters.
• Body (optional): explain "why", not "what".

5. Commit via heredoc

git commit -m "$(cat <<'EOF'
type(scope): subject line

Optional body.

Co-Authored-By: Claude <model> <noreply@anthropic.com>
EOF
)"

Replace <model> with the actual model name (e.g. Opus 4.6, Sonnet 4.6).

6. Handle pre-commit hook failure

Fix the issue, re-stage, and create a new commit. Never use --no-verify. Never amend — the failed commit does not exist.

Worktree Workflow

When working in a git worktree (.claude/worktrees/<name>/):

1. Smart commit all changes using the workflow above.
2. Switch to main in the primary working directory.
3. Squash-merge: git merge --squash <worktree-branch>.
4. Commit the squashed result with a single well-formed message.
5. Verify: git log --oneline -5 && git status.
6. Remove: git worktree remove.claude/worktrees/<name>.

Commit before merging, always merge into main, never delete the branch before merge is confirmed, use --squash for linear history.

Rules

• Proceed without confirmation — stage, generate message, and commit in one flow.
• Never commit sensitive files (run the guard first).
• Never amend a published commit — create a new one.
• Never force-push main.
• Never use --no-verify or --no-gpg-sign.
• Prefer named files over git add -A to avoid staging secrets or noise.

Quick Reference

• Sensitive File Guard → git add -u → multi-concern split → Conventional Commit via heredoc with Co-Authored-By.
• Worktree: commit → squash-merge to main → verify → remove.
