git-commit-helper

A helper that creates Git commit messages from the changes you staged. Git is a version-control system, and a staged change is one selected for the next commit.

In plain words
What is it for?
Use it when committing changes, when no commit message was supplied, or when you need a clear message based on the current Git diff.
Why use it?
It removes the need to summarize a diff manually and formats the result using Conventional Commits, a shared style such as feat, fix, or docs followed by a short description.

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

git-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 2d ago.

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.

Git Commit Helper Skill

Generate conventional commit messages from your git diff.

When I Activate

  • git commit without message
  • ✅ User asks "what should my commit message be?"
  • ✅ Staged changes exist
  • ✅ User mentions commit or conventional commits
  • ✅ Before creating commits

What I Generate

Conventional Commit Format

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

<body>

<footer>

Types:

  • feat: New feature
  • fix: Bug fix
  • docs: Documentation changes
  • style: Code style (formatting, no logic change)
  • refactor: Code refactoring
  • perf: Performance improvements
  • test: Test additions or fixes
  • build: Build system changes
  • ci: CI/CD changes
  • chore: Maintenance tasks

Examples

Feature Addition

# You staged:
git add auth.service.ts login.component.tsx

# I analyze diff and suggest:
feat(auth): add JWT-based user authentication

- Implement login/logout functionality
- Add token management service
- Include auth guards for protected routes
- Add unit tests for auth service

Closes #42

Bug Fix

# You staged:
git add UserList.tsx

# I suggest:
fix(components): resolve memory leak in UserList

Fixed subscription not being cleaned up in useEffect,
causing memory leak when component unmounts.

Closes #156

Breaking Change

# You staged:
git add api/users.ts

# I suggest:
feat(api): update user API response format

Changed response structure to include metadata
for better pagination and filtering support.

BREAKING CHANGE: User API now returns { data, metadata }
instead of direct array. Update client code accordingly.

Documentation Update

# You staged:
git add README.md docs/api.md

# I suggest:
docs: update API documentation with authentication examples

- Add authentication flow diagrams
- Include cURL examples for protected endpoints
- Document error responses

Analysis Process

Step 1: Check Staged Changes

Files

What ships with it

1 file 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.
