messygit 0.1.2

CLI that drafts Conventional Commits from staged git diffs with Claude, then commit, cancel, or edit.

messygit

messygit is a command-line tool that reads your staged Git changes, asks Claude (via the Anthropic API) to suggest a Conventional Commits subject line, and then lets you commit, cancel, or edit the message before running git commit.

Why use it

• Keeps commit subjects consistent (feat(scope): describe the change) without thinking up wording from scratch.
• Only the staged diff is sent to the model—what you git add is what gets summarized.
• The API key is never printed in full; show uses a masked preview.
• Clear errors for missing keys, rejected keys, and billing or zero-balance situations.

Requirements

• Python 3.10 or newer
• Git (run inside a repository)
• An Anthropic API key with access to the Messages API

Installation

pip install messygit

This installs the messygit command (see [project.scripts] in pyproject.toml).

Install from source

From a checkout of this project:

cd messygit
python -m venv .venv
source .venv/bin/activate   # Windows: .venv\Scripts\activate
pip install -e .

API key

messygit resolves the key in this order:

1. Environment variable ANTHROPIC_API_KEY
2. Config file ~/.messygit/config.json (written by messygit config)

If neither is set, the default command exits with a short message explaining how to fix it.

Save a key to the config file:

messygit config --key YOUR_ANTHROPIC_API_KEY

Show a masked key (which source is active, without revealing the secret):

messygit show

Usage

Typical flow:

git add .
messygit

1. If there is nothing staged, messygit tells you to run git add first.
2. Otherwise it sends the staged diff to Claude and prints a suggested one-line message.
3. You are prompted: commit (default), no (cancel), or edit (open $EDITOR to change the message).
4. On confirmation, it runs git commit -m "..." with your chosen text.

Commands

Command	Description
messygit	Generate a message from git diff --staged, then prompt to commit / cancel / edit.
messygit config --key KEY	Store the Anthropic API key under ~/.messygit/config.json.
messygit show	Print a masked API key and whether it comes from the environment or config file.

Commit message style

The model is instructed to follow Conventional Commits, for example:

feat(auth): validate refresh tokens

Allowed types include: feat, fix, docs, style, refactor, test, chore. Subjects are one line, imperative, lowercase, no trailing period, and kept within a reasonable length (see your prompts in the package if you customize behavior).

Development

Without installing the package, from the repository root (the directory that contains the messygit package folder):

.venv/bin/python -m messygit.cli

Subcommands:

python -m messygit.cli config --key YOUR_KEY
python -m messygit.cli show
