🐒 git-chimp

Because writing commit messages and pull requests sucks. Let the AI do it.

git-chimp automates your Git commits and pull requests using AI. It analyzes your staged changes or commit history, then generates surprisingly coherent commit messages and PRs—so you can stop typing “fix stuff” for the fifth time today.

⚠️ This is an early-stage tool! Features are limited, monkeys are still learning.

🧠 Features

• 🧵 git-chimp commit – GPT-powered commit message generation from staged changes
• 🚀 git-chimp pr – GPT-generated pull request descriptions from commit diffs
• 📝 git-chimp changelog – Auto-generate changelogs, with optional AI summaries
• ⚙️ git-chimp config – Manage .chimprc settings without editing the file
• 🧪 Supports both local and global .chimprc configs
• 🐙 Integrates with GitHub for PR management

Coming soon:

• 🔀 Branch naming assistant (git-chimp name or git-chimp branch)
• 🧪 Dry run support (--dry-run)
• 🍿 Emoji support and improved Conventional Commit modes

📦 Installation

npm install -g git-chimp

Or use it via npx:

npx git-chimp commit

🧠 Initialize Your Config with init

You can quickly create or update your .chimprc file using the built-in init command:

npx git-chimp init

You'll be prompted to choose:

• Local or Global config location
• Local: stored in ./.chimprc
• Global: stored in ~/.chimprc

Then you'll be walked through a few simple questions to generate the correct config for your project or environment. If a config already exists, it will be merged with your new choices — no overwrites or data loss.

Some fields (like openaiApiKey) are only written to global config for security and reusability.

• 🐙 GitHub Token: https://github.com/settings/tokens (Requires repo scope)

🛠 Configuration

[!WARNING]
The .git-chimprc file has been replaced with .chimprc. It will, however, continue to work - for now.

git-chimp supports configuration via the gitChimp namespace in a .chimprc file at the root of your repo. This should be a plain JSON file (no .json extension).

Example .chimprc:

{
  "gitChimp": {
    "model": "gpt-3.5-turbo",
    "tone": "sarcastic",
    "prMode": "draft",
    "enforceSemanticPrTitles": true,
    "enforceConventionalCommits": true,
    "changelog": {
      "aiSummary": true,
      "output": "CHANGELOG.md",
      "from": "v1.0.0",
      "to": "HEAD"
    }
  }
}

Config Options

Key	Type	Description
tone	string	Sets the writing style (e.g., "corporate-safe", "dry sarcasm", "chaotic evil")
model	string	OpenAI model to use (gpt-3.5-turbo, gpt-4, gpt-4o, gpt-4o-mini)
enforceConventionalCommits	boolean	If true, enforces Conventional Commit style
enforceSemanticPrTitles	boolean	If true, enforces semantic PR titles (e.g., feat: prefix)
prMode	string	PR mode: open (default), draft, display
changelog	object	Changelog generation options (see below)

changelog options:

Key	Type	Description
aiSummary	boolean	If true, generates an AI summary section for the changelog
output	string	File path to write or append changelog content (e.g., "CHANGELOG.md")
from	string	Git tag or commit to start from (e.g., "v1.0.0")
to	string	Git ref to end at (defaults to HEAD if omitted)

🛠 Config Commands

You can use git-chimp config to manage settings in your .chimprc without editing the file manually (though you still can if you like that sort of thing).

Prints all current config values under the gitChimp namespace.

Gets the value of a specific config key.

config set

💡 Pro Tip

The config system is merge-friendly. It works like this (highest priority wins):

• Command-line flags (e.g., --tone)
• .chimprc config
• Defaults baked into the tool

So yeah — you can go full control freak without ever touching a config file, or commit to the chimp with a persistent setup.

🧨 Can I override git commit?

Yes... but with caution. You can alias git commit to use git-chimp, but this disables standard Git commit behavior.

Here’s an alias override (not recommended unless you're into danger):

git config --global alias.commit '!git-chimp commit'

For a safer setup, try:

git config --global alias.chimp-commit '!git-chimp commit'
git config --global alias.chimp-pr '!git-chimp pr'

Then use:

git chimp-commit
git chimp-pr

Or if you're lazy and proud:

alias gc='git-chimp commit'
alias gp='git-chimp pr'
