About this skill
Writing good commit messages is often the last thing developers want to spend time on, yet messy commit history makes debugging, reviewing, and onboarding harder. This skill takes a git diff, staged changes, or a plain description of what changed and turns it into a clear, specific commit message — following conventional commit format when appropriate, with a body when the change needs context. It can also split unrelated changes into multiple commits, generate changelog-ready summaries, and draft PR-friendly change descriptions, all while flagging any secrets that shouldn't be committed.
What it does
- Writes clear, specific commit titles in conventional commit format
- Adds a detailed commit body when the change needs context
- Detects when a diff contains unrelated changes and suggests splitting into multiple commits
- Generates changelog-ready summaries
- Drafts pull-request-friendly change descriptions
- Flags potential secrets or sensitive data found in a diff
What is included
- Concise runtime skill definition for generating commit messages
- Full workflow for classifying and writing commits
- Complete commit style guide with conventional commit types and examples
- Ready-to-use templates for single, grouped, and changelog-style commits
- Worked examples covering features, bug fixes, and mixed-change splits
How to use it
1. Share a git diff, staged changes, list of changed files, or a description of the change. 2. Mention your preferred commit style if you have one (conventional, short, or detailed). 3. Say whether you want one commit or a split into multiple commits. 4. Review the generated commit title, body, or grouped commit plan. 5. Copy the ready-to-use git commit command directly into your terminal.
Examples
I added a password reset flow to the auth module. Write a commit message.
A conventional commit — feat(auth): add password reset flow — with a body explaining what changed, why, and any relevant notes, formatted as a ready-to-run git commit command.
