Git Commit

Staged Changes

Run git status to see what changes are staged for commit. If there are no staged changes, stage all modified files.

Title

Create a clear, succinct title that explains what the commit accomplishes. Brief - only the essentials.

Use imperative mood: "Add feature" not "Added feature" or "Adds feature"

Good examples:

• Add user authentication
• Fix memory leak in parser
• Update dependencies
• Remove deprecated API endpoints

Avoid overly detailed titles and phrases like "This commit..." or "Changes to..."

Body

MOST COMMITS SHOULD HAVE NO BODY. DO NOT ADD A BODY UNLESS ABSOLUTELY NECESSARY. A title-only commit is almost always better.

Before adding a body, ask yourself: Does this body add information that isn't obvious from the title? If the body just expands on what the title already says, delete it.

Bad example:

Add writing-markdown skill

- Add SKILL.md with instructions
- Add scripts/resource-paths script

The body just restates "Add writing-markdown skill" in more words. Delete the body.

Only add a body when the title genuinely can't capture important context. The body must contain non-redundant detail that adds real value.

Write bodies in markdown. Use markdown formatting for lists, emphasis, code, etc.

Common patterns (only when a body is truly necessary):

• Simple context (1-2 sentences): Explain the "why" or rationale when it's not obvious
• Bullet list: List specific changes when there are multiple distinct items
• Paragraph + bullet list: Provide context, then list specific changes under a "Changes:" header
• Multiple sections: Use headers to organize complex changes (e.g., "Changes:" and "Template-specific changes:")

The title says "what" - the body explains "why" or provides specific details

Formatting

YOU MUST use the format script before outputting the final commit message.

Run the format script with your drafted title and body:

./format-commit-message.sh --title "Your commit title" --body "Your commit body"

Create Commit

After formatting, create the commit using the formatted message. Use a heredoc to preserve formatting:

git commit -m "$(cat <<'EOF'
Commit title here

Optional body here.
EOF
)"

Rationalizations

REQUIRED: See references/examples.md for correct formatting.
