# git-commit

Reads your diff, picks the commit type and scope, and writes a Conventional Commits message. Handy when every commit ends up as fix or update.

## What it does

The skill inspects the changes in your repo and decides the type itself: `feat`, `fix`, `docs`, `refactor`, `perf`, `test`, `build`, `ci`, `chore`, `revert`. It then suggests a scope and a one-line description in imperative mood, under 72 characters. Breaking changes get an exclamation mark after the type or scope, or a `BREAKING CHANGE` footer.

The flow is straightforward. It runs `git diff --staged` first, falls back to `git diff` on the working tree when the index is empty, and checks `git status --porcelain` along the way. If nothing is staged, or the changes deserve separate commits, it stages files by path, by pattern such as `*.test.*`, or through `git add -p`. Then it builds the message and calls `git commit -m`. You can override type, scope and description by hand.

Bash is the only tool the skill is allowed to use. A safety protocol sits in the instructions: no touching git config, no `--force` or hard reset unless you ask, no `--no-verify` to skip hooks, no force push to main or master. Secrets like `.env`, `credentials.json` and private keys should stay out of the commit. When a hook rejects the commit, the skill fixes the problem and creates a new commit instead of amending.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add ilteoood/harness --skill git-commit -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/git-commit/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/git-commit/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add ilteoood/harness --skill git-commit -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/git-commit/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add ilteoood/harness --skill git-commit -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/git-commit/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install ilteoood/harness git-commit
```

2. **Manually: put the files in place**
- File: `.github/skills/git-commit/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add ilteoood/harness --skill git-commit -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/ilteoood/harness --path skills/core/git-commit
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/git-commit/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add ilteoood/harness --skill git-commit -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/ilteoood/harness/tree/HEAD/skills/core/git-commit/SKILL.md

## When to use it
- write a Conventional Commits message without reading the diff yourself
- split a messy working tree into several logical commits
- flag a breaking change so release tooling picks it up
- keep `.env` files and private keys out of a commit
- make commit history follow one style

## Example prompts
- commit the changes in src/components
- make a commit with type feat and scope api
- commit only the test files, leave the rest alone

# Git Commit with Conventional Commits

## Overview

Create standardized, semantic git commits using the Conventional Commits specification. Analyze the actual diff to determine appropriate type, scope, and message.

## Conventional Commit Format

```
<type>[optional scope]: <description>

[optional body]

[optional footer(s)]
```

## Commit Types

| Type       | Purpose                        |
| ---------- | ------------------------------ |
| `feat`     | New feature                    |
| `fix`      | Bug fix                        |
| `docs`     | Documentation only             |
| `style`    | Formatting/style (no logic)    |
| `refactor` | Code refactor (no feature/fix) |
| `perf`     | Performance improvement        |
| `test`     | Add/update tests               |
| `build`    | Build system/dependencies      |
| `ci`       | CI/config changes              |
| `chore`    | Maintenance/misc               |
| `revert`   | Revert commit                  |

## Breaking Changes

```
# Exclamation mark after type/scope
feat!: remove deprecated endpoint

# BREAKING CHANGE footer
feat: allow config to extend other configs

BREAKING CHANGE: `extends` key behavior changed
```

## Workflow

### 1. Analyze Diff

```bash
# If files are staged, use staged diff
git diff --staged

# If nothing staged, use working tree diff
git diff

# Also check status
git status --porcelain
```

### 2. Stage Files (if needed)

If nothing is staged or you want to group changes differently:

```bash
# Stage specific files
git add path/to/file1 path/to/file2

# Stage by pattern
git add *.test.*
git add src/components/*

# Interactive staging
git add -p
```

**Never commit secrets** (.env, credentials.json, private keys).

### 3. Generate Commit Message

Analyze the diff to determine:

- **Type**: What kind of change is this?
- **Scope**: What area/module is affected?
- **Description**: One-line summary of what changed (present tense, imperative mood, <72 chars)

### 4. Execute Commit

```bash
# Single line
git commit -m "<type>[scope]: <description>"

# Multi-line with body/footer
git commit -m "$(cat <<'EOF'
<type>[scope]: <description>

<optional body>

<optional footer>
EOF
)"
```
