# smart-commit

A Claude hook that commits the changed file right after Edit or Write. Useful when you would rather not build git history by hand.

## What it does

smart-commit attaches to `PostToolUse` events for the `Edit` and `Write` tools. Once Claude has changed a file, the hook checks that you are inside a git repository, stages the file and commits it. For edits the message is built from the file name and the size of the change: under 10 lines is `minor`, under 50 is `moderate`, anything larger is `major`. New files get a simpler message with `Add new file` and the name.

There is no script to maintain. Two shell commands live in `.claude/settings.json` and lean on `git add`, `git diff --cached --numstat` and `git commit`. If the file has not changed or the commit fails, the hook exits quietly, so you will not see an error.

The catch: a commit fires for every changed file right after each edit. On a repo with many small tweaks the log fills up with near-identical entries, and you never write the message yourself. Worth testing on a throwaway branch first.

## Install

### Claude Code (native platform)

1. **claude-code-templates**
```bash
npx claude-code-templates@latest --hook git-workflow/smart-commit
```

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-workflow/smart-commit.json

## When to use it
- record a file edit in git without a manual commit
- keep a change history while the agent works
- separate small edits from large ones by line count
- commit a freshly created file
- stop forgetting git during a Claude session

## Example prompts
- Edit `src/api/client.js` and let smart-commit handle the commit
- Create `docs/setup.md` — the hook will commit it
- Check `git log` to confirm a new commit appeared after the edit
