✍️ Git Commit Writer
Generate Conventional Commit messages from your staged git diff: auto-detects type and scope from the changed files, flags breaking changes, and keeps work-in-progress out of the message. Clean, searchable history that plays nicely with automated changelog tools.

About this skill
What it does
The Git Commit Writer automates the process of crafting high-quality, professional commit messages. It analyzes your staged changes using git diff --cached to generate messages following the Conventional Commits specification. It intelligently detects the correct change type, identifies the relevant scope based on your file paths, and flags breaking changes automatically.
How it works
The skill follows a rigorous multi-step analytical process:
- Verifies staged files via
git statusto ensure it only commits what you've actually added. - Summarizes impact using
--statand inspects logic changes within patch files. - Applies Scope Detection Rules to map file paths (like
src/auth/) to logical scopes (likeauth). - Evaluates breaking change indicators, such as signature changes or schema modifications.
Why use this skill
Writing good commits is hard, especially when context-switching. While a basic AI might just summarize what you did, this developer-centric skill ensures your repo history remains clean, searchable, and compatible with automated changelog tools. It prevents common mistakes like including unstaged "work-in-progress" code in the message description or using non-standard types.
Supported tools
Designed for any AI agent with shell access (CLI), it specifically targets environments like Claude Code, Cursor, and Windsurf where git is available in the integrated terminal.

Allowed Hosts
Git Commit Writer needs terminal access to run read-only git commands: `git diff --cached` (to see staged changes) and `git status --short` (to understand file state). It never runs destructive git commands like `git commit` itself — the user types the commit message manually.
