git-commit - SKILL.md Agent Skill

name: git-commit description: Compose CI-valid commit messages with Jira linking and sign-off. Use when the user asks to commit, write a commit message, or git commit. Never execute the commit — only present the message and command for the user to run.

Git Commit Skill

Never run git add or git commit yourself. The user will review, adjust if needed, and execute the commit manually.

For full commit message validation rules, formats, and troubleshooting, see commit-message-guide.md in this skill directory.

Step 1: Check Branch

Run git branch --show-current. If on main, warn the user and ask if they want to continue or switch to a new branch first.

Step 2: Gather Info

Use AskQuestion to ask:

Jira issue ID (e.g. MTV-1234) — if "None", ask for chore type (deps, docs, ci, test, refactor, lint, build)
Add AI co-author line? (Yes / No)

Step 3: Analyze Changes

Run git diff HEAD and git status to see all changes since the last commit (staged, unstaged, and untracked files). Use these diffs to understand what changed and why.

Step 4: Generate Commit Message

Format:

MTV-XXXX | <imperative description, ~72 chars total>

<body: what changed and why, lines wrapped at 72 chars>

Ref: https://redhat.atlassian.net/browse/MTV-XXXX
Resolves: MTV-XXXX

Title (~72 chars max, imperative mood):

With Jira: MTV-XXXX | description
Without Jira: chore(type): description (skips CI — no Ref:/Resolves: needed)

Trailers (with Jira only):

Ref: https://redhat.atlassian.net/browse/MTV-XXXX
Resolves: MTV-XXXX (required by CI)

If co-author requested, append: Co-authored-by: AI Assistant <noreply@cursor.com>

Step 5: Present Message and Command

Present the full commit message in a code block, followed by a ready-to-run git command the user can copy-paste:

git add <relevant files>
git commit -s -m "$(cat <<'EOF'
<the commit message>
EOF
)"
