noidea 0.4.0

AI powered commit suggestions

noidea

AI-powered commit message suggestions via git hooks. Stages a diff, sends it to Claude, and pre-fills your commit editor.

Demo

Install

pipx install noidea
noidea init

Requires pipx. Alternatively: pip install noidea

noidea init installs a prepare-commit-msg hook in your repo. From then on, every git commit opens your editor with a suggested message pre-filled.

API Key Setup

noidea needs an Anthropic API key. Three options (checked in order):

1. Keyring (recommended): noidea keys add
2. Environment variable: export ANTHROPIC_API_KEY=sk-ant-...
3. .env file: ANTHROPIC_API_KEY=sk-ant-... in a .env file

Commands

noidea init

Installs the prepare-commit-msg hook. Backs up any existing hook as .bak. Respects core.hooksPath.

noidea suggest

Generates a commit message from the current staged diff and prints it.

Options:
  -F, --file TEXT    Write message to file instead of stdout (used by the hook)
  -M, --model TEXT   Override the model used for generation

noidea keys

Manage API keys stored in the system keyring.

noidea keys show    # Show saved keys
noidea keys add     # Add a key interactively
noidea keys remove  # Remove a key interactively

noidea test

Sends a test message to the Claude API to verify your key and connectivity work.

noidea update

Updates noidea via pipx upgrade noidea (falls back to pip install --upgrade noidea).

noidea --version

Prints the current version.

Config

Optional config at ~/.noidea/config.json:

{
  "llm": {
    "max_tokens": 1024,
    "small_model": "claude-haiku-4-5",
    "large_model": "claude-sonnet-4-6",
    "context_limit": 600000,
    "system_prompt": "Your custom prompt here"
  }
}

Falls back to built-in defaults if no config file exists. The default prompt follows conventional commits style (feat/fix/refactor/etc.) with a 72-character subject line limit. Smaller diffs use small_model (Haiku) for speed; larger diffs automatically switch to large_model (Sonnet).

Requirements

• Python 3.10+
• Anthropic API key
