This hook checks Git commit messages against the Conventional Commits pattern. Use it when commit history needs to support changelogs and semantic versioning.

## What it does

The hook attaches to the `PreToolUse` event for `Bash` and runs `.claude/hooks/conventional-commits.py`. Before a commit is created, it checks the message against `type(scope): description`.

Accepted types are `feat`, `fix`, `docs`, `style`, `refactor`, `perf`, `test`, `chore`, `ci`, `build`, and `revert`. Keeping these labels consistent makes the Git history usable for changelog generation and semantic versioning. The check will not run without `python3`.

## Install

### Claude Code (native platform)

1. **claude-code-templates**
```bash
npx claude-code-templates@latest --hook git/conventional-commits
```

2. **Manually: put the files in place**
- File: `.claude/settings.json` — The hooks block: event (PreToolUse, PostToolUse, Stop…) → command. Personal ones go to ~/.claude/settings.json

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/davila7/claude-code-templates/tree/HEAD/cli-tool/components/hooks/git/conventional-commits.json

## When to use it
- validate Git commit messages
- enforce the `type(scope): description` pattern
- reject unsupported commit types
- keep history ready for changelogs and semantic versioning

## Example prompts
- Create a commit with the message `feat(auth): add GitHub sign-in`.
- Commit the email validation fix as `fix(forms): correct email checking`.
- Make a documentation commit using the `docs` type and a short description.
