# Commit Message Preparation

This prompt shapes Git commit messages around Conventional Commits, with a type, scope, subject, body, and optional footer. Use it when reviewing a diff.

## What it does

The prompt asks for the change and its reason instead of a description of implementation details. It defines a structure with a type, an optional scope, a short subject, a required body, and an optional footer. The rules require imperative wording, a subject no longer than 50 characters, and body lines wrapped at 72 characters.

It covers `feat`, `fix`, `refactor`, `perf`, `style`, `test`, `docs`, `build`, `ci`, `chore`, and `revert`. It also separates independent changes into different commits, allows issue references, and gives a format for breaking changes. A banned-words section filters vague or exaggerated wording.

For Claude Code, the listed path is `.claude/commands/prompts.csv.md`. Check the project’s command setup before relying on that location.

## Install

### ChatGPT (native platform)

**How to use**
- Paste the text at the start of a chat or into project instructions

### Claude Code

**Manually: put the files in place**
- File: `.claude/commands/prompts.csv.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/f/prompts.chat/tree/HEAD/prompts.csv

## When to use it
- write a commit message in Conventional Commits format
- choose the right commit type and scope
- explain a change and its reason in the body
- split independent changes into separate commits
- remove vague wording from commit messages

## Example prompts
- Prepare a commit message from the current diff. Choose the Conventional Commits type and scope, then include a body that explains what changed and why.
- Review the changes in `LoginView` and suggest separate commits for independent work. Follow the subject limits and include a body for each message.
- Write a commit message for the fix that prevents a form from being submitted twice. Use imperative wording and a specific subject.

# Git Commit Guidelines for AI Language Models

## Core Principles

1. **Follow Conventional Commits** (https://www.conventionalcommits.org/)
2. **Be concise and precise** - No flowery language, superlatives, or unnecessary adjectives
3. **Focus on WHAT changed, not HOW it works** - Describe the change, not implementation details
4. **One logical change per commit** - Split related but independent changes into separate commits
5. **Write in imperative mood** - "Add feature" not "Added feature" or "Adds feature"
6. **Always include body text** - Never use subject-only commits

## Commit Message Structure

```
<type>(<scope>): <subject>

<body>

<footer>
```

### Type (Required)

- `feat`: New feature
- `fix`: Bug fix
- `refactor`: Code change that neither fixes a bug nor adds a feature
- `perf`: Performance improvement
- `style`: Code style changes (formatting, missing semicolons, etc.)
- `test`: Adding or updating tests
- `docs`: Documentation changes
- `build`: Build system or external dependencies (npm, gradle, Xcode, SPM)
- `ci`: CI/CD pipeline changes
- `chore`: Routine tasks (gitignore, config files, maintenance)
- `revert`: Revert a previous commit

### Scope (Optional but Recommended)

Indicates the area of change: `auth`, `ui`, `api`, `db`, `i18n`, `analytics`, etc.

### Subject (Required)

- **Max 50 characters**
- **Lowercase first letter** (unless it's a proper noun)
- **No period at the end**
- **Imperative mood**: "add" not "added" or "adds"
- **Be specific**: "add email validation" not "add validation"

### Body (Required)

- **Always include body text** - Minimum 1 sentence
- **Explain WHAT changed and WHY** - Provide context
- **Wrap at 72 characters**
- **Separate from subject with blank line**
- **Use bullet points for multiple changes** (use `-` or `*`)
- **Reference issue numbers** if applicable
- **Mention specific classes/functions/files when relevant**

### Footer (Optional)

- **Breaking changes**: `BREAKING CHANGE: <description>`
- **Issue references**: `Closes #123`, `Fixes #456`
- **Co-authors**: `Co-Authored-By: Name <email>`

## Banned Words & Phrases

**NEVER use these words** (they're vague, subjective, or exaggerated):

❌ Comprehensive
❌ Robust
❌ Enhanced
❌ Improved (unless you specify what metric improved)
❌ Optimized (unless you specify what metric improved)
❌ Better
❌ Awesome
❌ Great
❌ Amazing
❌ Powerful
❌ Seamless
❌ Elegant
❌ Clean
❌ Modern
❌ Advanced

## Good vs Bad Examples

### ❌ BAD (No body)
```
feat(auth): add email/password login
```

**Problems:**
- No body text
- Doesn't explain what was actually implemented

### ❌ BAD (Vague body)
```
feat: Add awesome new login feature

This commit adds a powerful new login system with robust authentication
and enhanced security features. The implementation is clean and modern.
```

**Problems:**
- Subjective adjectives (awesome, powerful, robust, enhanced, clean, modern)
- Doesn't specify what was added
- Body describes quality, not functionality

### ✅ GOOD
```
feat(auth): add email/password login with Firebase

Implement login flow using Firebase Authentication. Users can now sign in
with email and password. Includes client-side email validation and error
handling for network failures and invalid credentials.
```

**Why it's good:**
- Specific technology mentioned (Firebase)
- Clear scope (auth)
- Body describes what functionality was added
- Explains what error handling covers

---

### ❌ BAD (No body)
```
fix(auth): prevent login button double-tap
```

**Problems:**
- No body text explaining the fix

### ✅ GOOD
```
fix(auth): prevent login button double-tap

Disable login button after first tap to prevent duplicate authentication
requests when user taps multiple times quickly. Button re-enables after
authentication completes or fails.
```

**Why it's good:**
- Imperative mood
- Specific problem described
- Body explains both the issue and solution approach

---

### ❌ BAD
```
refactor(auth): extract helper functions

Make code better and more maintainable by extracting functions.
```
