git-commit - SKILL.md Agent Skill

name: git-commit description: Use when the user asks to commit changes, stage and commit, or says "commit my changes" — stages all uncommitted changes and creates a structured commit message with emoji, title, and summary

Git Commit

Overview

Stages and commits all uncommitted changes with a structured message: a random emoji, a concise title, and a short summary. Optionally adds a Co-Authored-By line if the user mentions agent helped.

Permissions required: git commit, git rebase

Commit Message Format

[emoji] [title]

[summary — 1 to 5 lines depending on complexity]

With co-authorship:

[emoji] [title]

[summary — 1 to 5 lines depending on complexity]

Co-Authored-By: [model-name] [model-version] <model-email>

Rules:

Title line (emoji + text): max 100 characters
Summary lines: max 100 characters each
Summary length: 1 line for trivial changes, up to 5 lines for complex ones
Emoji: pick a random emoji, do not map specific emojis to change types
Co-authorship: add only when the user explicitly says Claude helped or co-authored

Steps

Run git diff and git status to understand all uncommitted changes
Analyze the changes to determine:
- A concise, descriptive title
- An appropriate emoji
- A summary proportional to complexity
Stage changes: git add <specific files> — avoid git add -A unless all changes should be committed
Commit using a HEREDOC to preserve formatting:

git commit -m "$(cat <<'EOF'
🔧 Title of the change

Summary of the change, respecting the 100-char line limit.
Add more lines only if the change is complex enough to warrant it.
EOF
)"

With co-authorship:

git commit -m "$(cat <<'EOF'
✨ Title of the change

Summary of the change.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
EOF
)"

Run git status to confirm the commit succeeded

Co-Authorship

Use the model name and version from the current environment. The model ID claude-sonnet-4-6 becomes Claude Sonnet 4.6. Format:

Co-Authored-By: Claude [Model Name] [Version] <noreply@anthropic.com>

Common Mistakes

Mistake	Fix
Title over 100 chars	Shorten — cut adjectives, use imperative verbs
Summary too long for a trivial change	1 line is enough for small fixes
Adding co-authorship unprompted	Only add when user explicitly requests it
Using `git add -A` blindly	Stage specific files to avoid committing secrets or unrelated work
Skipping `git status` after commit	Always verify the commit landed correctly
