A guide for writing Git commit messages in the Conventional Commits format, a shared style that labels changes such as features, fixes, tests, and documentation.

In plain words
What is it for?
Use it when creating or formatting commit messages, choosing a change type and scope, and documenting the change body or footer.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

commit-helper scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/validate_commit.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Commit Message Helper

A skill for creating properly formatted Git commit messages following the Conventional Commits specification.

When This Skill Activates

This skill activates when you:

  • Ask to commit changes
  • Mention commit messages
  • Request git commit formatting
  • Say "commit" or "git commit"

Commit Message Format

<type>(<scope>): <subject>

<body>

<footer>

Types

Type Description
feat A new feature
fix A bug fix
docs Documentation only changes
style Changes that do not affect the meaning of the code (formatting, etc.)
refactor A code change that neither fixes a bug nor adds a feature
perf A code change that improves performance
test Adding missing tests or correcting existing tests
chore Changes to the build process or auxiliary tools
ci Changes to CI configuration files and scripts
build Changes that affect the build system or external dependencies

Scope

The scope should indicate the area of the codebase affected:

  • For frontend: components, hooks, store, styles, utils
  • For backend: api, models, services, database, auth
  • For devops: ci, deploy, docker
  • Project-specific scopes are also acceptable

Guidelines

Subject Line

  • Use imperative mood ("add feature" not "added feature" or "adds feature")
  • No period at the end
  • Maximum 50 characters
  • Be specific and concise

Body

  • Separate subject from body with a blank line
  • Use the body to explain what and why, not how
  • Wrap at 72 characters per line
  • Mention any breaking changes

Footer

  • Reference issues: Closes #123, Fixes #456, Refs #789
  • Multiple issues: Closes #123, #456, #789
  • Breaking changes: Start with BREAKING CHANGE: followed by description

Examples

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
