Git Commit Skill

Analyze changes in the current git repository and create well-structured conventional commits.

Workflow

1. Gather repository state

Run these three commands in parallel to understand the current state:

git status --porcelain
git diff --staged
git diff

Also run in parallel:

git branch --show-current
git log --oneline -10

2. Determine what to commit

If changes are staged (git diff --staged has output):

• •Proceed with staged changes only.

If nothing is staged but unstaged changes exist:

• •Ask the user what to stage, or suggest staging all modified tracked files with git add -u.
• •NEVER blindly run git add -A or git add . — these can stage secrets, build artifacts, or untracked files the user didn't intend to commit.

If nothing changed:

• •Inform the user there are no changes to commit. Stop.

3. Analyze changes

Read the diff carefully to understand:

• •What changed (files, functions, logic)
• •Why it changed (bug fix, new feature, refactor, docs, etc.)
• •Scope of change (single module, cross-cutting, config-only)

4. Detect project commit style

Examine the last 10 commits from git log --oneline -10:

• •If the project uses Conventional Commits (type(scope): description), follow that format.
• •If the project uses a different style (e.g., prefixed tags, plain descriptions), match it.
• •If no clear pattern exists, default to Conventional Commits.

5. Stage files

# Prefer explicit file paths
git add path/to/file1 path/to/file2

# Or stage all tracked changes if user confirms
git add -u

NEVER stage files that likely contain secrets: .env, *.pem, *.key, credentials, tokens.

6. Generate commit message

Follow the detected project style. For Conventional Commits:

<type>(<scope>): <description>

<optional body>

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

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

Rules:

• •Imperative mood, present tense: "add feature", not "added feature"
• •Description under 72 characters
• •One logical change per commit
• •Body explains why, not what (the diff shows what)
• •Always analyze the actual diff content to determine type and scope
• •Include Co-Authored-By trailer

7. Commit

git commit -m "$(cat <<'EOF'
<type>(<scope>): <description>

<optional body>

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
EOF
)"

8. Post-commit

After a successful commit, run git status to confirm clean state.

9. Push (if requested)

Argument parsing: Check if the user passed push as an argument (e.g., /commit push).

If push argument is present:

# Push to the current branch's upstream
git push

If push fails due to no upstream, set it:

git push -u origin $(git branch --show-current)

If push argument is NOT present, do NOT push.

Safety

• •NEVER update git config
• •NEVER run destructive commands (--force, reset --hard, checkout ., clean -f) unless explicitly requested
• •NEVER skip hooks (--no-verify) unless explicitly requested
• •If commit fails due to pre-commit hooks, fix the issue and create a NEW commit (never amend the previous one)
• •NEVER commit files that may contain secrets
• •If uncertain about what to stage, ask the user
