git-gen

A Bun CLI that analyzes git changes and uses Claude to generate commit messages and PR bodies following your team's conventions.

Setup

bun install

Requires Claude Code to be installed and authenticated.

Usage

bun run index.ts           # default: runs generate
bun run index.ts generate  # same as above
bun run index.ts help      # show help

Prompt Files

The CLI auto-detects your project by matching the current directory against prompt files in src/prompt/.

To add your team's conventions, create a markdown file:

src/prompt/<name>.md

The <name> should match a segment in your project path. For example, if you work in /Users/you/work/acme/app, create src/prompt/acme.md.

The prompt file should describe your commit message format, PR title/body conventions, and any relevant prefixes or templates. See src/prompt/example.md for a reference.
