git-cai-cli 0.7.2

Use LLM to create git commit messages

cai

cai is a Git extension that automates the creation of commit messages.
Simply run git cai to generate a meaningful, context-aware commit message based on the changes in your repository.

cai uses a Large Language Model (LLM) to analyse diffs and new files, producing concise and informative commit messages.

Currently supported providers:

• OpenAI
• Gemini
• Anthropic
• Groq
• xAI
• Mistral
• DeepSeek

---

Prerequisites

• Python 3.10 or higher
• pipx
• An API key for at least one of the following providers:
  • OpenAI
  • Gemini (free tier available)
  • Anthropic
  • Groq (free tier available)
  • xAI
  • Mistral
  • DeepSeek

---

Features

• Automatically detects added, modified, and deleted files
• Generates meaningful, context-aware commit messages using an LLM
• Seamless integration with Git
• Supports multiple LLM providers and models
• Global configuration with per-repository overrides
• Repository-specific language, style, and model selection
• Optional commit squashing with automatic summary generation

---

Installation

Install cai using pipx:

pipx install git-cai-cli

Ensure that pipx binaries are available in your PATH:

pipx ensurepath

Restart your shell after installation.

If you are running Arch Linux or an Arch-based distribution such as EndeavourOS, CachyOS, etc., you can install the package from the AUR using a package manager like Paru.

paru -S cai

---

Usage

Once installed, cai works like a standard Git command:

git cai

cai uses the output of git diff to generate a commit message.
The generated message is opened in your configured Git editor, allowing you to review or edit it before committing.

In short: it behaves like git commit, but the commit message is pre-filled.

Ignoring files

To exclude specific files or directories from being considered when generating commit messages, create a .caiignore file in the root of your repository.

• Files listed in .gitignore are always excluded
• .caiignore is intended for tracked files that should not influence commit messages

The syntax is identical to .gitignore.

---

Configuration

On first execution, cai automatically creates two configuration files:

• Global configuration:
  ~/.config/cai/cai_config.yml

• API tokens:
  ~/.config/cai/tokens.yml

Don't be scared the first run will show an error. It only misses a token. Add your provider API keys to tokens.yml. Once configured, cai will reuse them automatically. Set your preferred LLM in cai_config.yml (Groq by default).

Repository-specific configuration

Each repository can be configured independently.

If a cai_config.yml file exists in the root of a repository, cai will use it instead of the global configuration.
This allows different projects to use different providers, models, languages, and styles.

Examples of per-repository customization:

• Different LLM providers or models
• Different commit message languages
• Different writing styles or tones
• Emojis enabled or disabled per project

To create a repository-specific configuration:

cp ~/.config/cai/cai_config.yml .

Modify the copied file as needed. As an alternative execute:

git cai -g

Available configuration options

• default – default LLM provider
• model – model to use for the selected provider
  (note: not all models may be compatible)
• temperature – controls how creative the generated messages are
• language – language used for commit messages
• style – tone or style of the commit message
• emoji – enable or disable emojis
• load_tokens_from – path to the file where API tokens are stored

---

CLI

In addition to git cai, the following options are available:

• -h --help – show help and available commands
• -a, --all – stage all tracked modified and deleted files
• -c, --crazy – Trust the LLM and commit without checking
• -d, --debug – enable debug logging
• -g, --generate-config – generate the default git_config.yml in the current directory
• -l, --list – list available languages and styles
• -s, --squash – squash commits on the current branch and summarize them
• -u, --update – check for updates
• -v, --version – show the installed version
