commit

name	commit
description	Stages files, generates a conventional commit message from the diff, and commits. Use this skill whenever the user asks to commit, save changes, make a commit, stage and commit, or says things like "commit this", "commit my changes", "save my work to git", or "create a commit". Also trigger when the user uses shorthand like /commit.

Git Commit Skill

Stage changes, generate a clear commit message, and commit — all in one step.

Workflow

1. Gather context

Run these in parallel:

• git status — see what's changed (never use -uall)
• git diff and git diff --cached — see staged and unstaged changes
• git log --oneline -5 — match the repo's commit style

2. Check for sensitive files

Before staging, scan for files that should not be committed:

• .env, .env.*
• credentials.json, secrets.*, *.pem, *.key
• Any file matching common secret patterns

If found, warn the user and exclude them from staging. Only commit them if the user explicitly confirms.

3. Stage files

• If files are already staged, respect that selection and only add unstaged changes if they're clearly related.
• If nothing is staged, stage all modified and new files (except sensitive ones).
• Prefer git add <specific-files> over git add . when there are fewer than 10 files, to keep things explicit.

4. Generate a commit message

Use conventional commits format:

<type>(<optional scope>): <short summary>

<optional body — what and why, not how>

Types: feat, fix, docs, style, refactor, test, chore, build, ci, perf

Rules for the message:

• Summary line under 72 characters, lowercase, no period
• Pick the type based on what the change actually does, not what files changed
• Scope is optional — use it when changes are clearly scoped to one module/area
• Add a body only when the "why" isn't obvious from the summary
• If changes span multiple concerns, pick the dominant one for the type

Examples:

feat(auth): add JWT token refresh on expiry

fix: prevent duplicate entries in search results

The deduplication filter was applied after pagination,
causing duplicates when results spanned page boundaries.

chore: update dependencies and lock file

5. Commit

Use a heredoc to preserve formatting:

git commit -m "$(cat <<'EOF'
feat(scope): summary here

Optional body here.

Co-Authored-By: Claude <[e-mail]>
EOF
)"

Always append the Co-Authored-By trailer.

6. Confirm

Run git status after committing to verify it succeeded. Report the commit hash and summary to the user.

What this skill does NOT do

• Push — never push unless the user explicitly asks
• Amend — always create a new commit unless told otherwise
• Force anything — no --force, no --no-verify, no skipping hooks
• Interactive git — no -i flags (not supported in this environment)

If a pre-commit hook fails, fix the issue, re-stage, and create a new commit (don't amend).
