cmt

AI-powered git commit messages. Fast.

Generates conventional commit messages from your staged diff using Claude.

Install

# Run directly
npx @fridzema/cmt        # npm
yarn dlx @fridzema/cmt   # yarn
bunx @fridzema/cmt       # bun

# Install globally
npm i -g @fridzema/cmt
yarn global add @fridzema/cmt
bun add -g @fridzema/cmt

Prerequisites

• git
• Claude CLI (claude)

Usage

# Generate a commit message (interactive)
cmt

# Skip confirmation, commit immediately
cmt --direct

# Commit with a specific message
cmt "feat: add user auth"

# Use a different model (default: haiku)
cmt --model sonnet

# Skip automatic git add
cmt --no-add

Options

-d, --direct          Skip confirmation, commit immediately
-m, --model <model>   Claude model to use (default: haiku)
--no-add              Skip automatic 'git add -A'
-v, --version         Show version
-h, --help            Show help

How it works

1. Stages all changes (git add -A, unless --no-add)
2. Sends the diff to Claude
3. Gets back a conventional commit message
4. Shows the message for confirmation:
   • Accept — commit as-is
   • Edit — type your own message
   • Regenerate — ask Claude for a new message
   • Quit — abort without committing
5. Use --direct to skip confirmation and commit immediately
