Provider-agnostic code review using AI
Use Claude, Gemini, Codex, OpenCode, Cursor Agent, Kilo, Kiro, Ollama, LM Studio, GitHub Models, MiniMax, or any AI to enforce your coding standards.
Pure Bash core. Works everywhere.

🎯 Why?
You have coding standards. Your team ignores them. Code reviews catch issues too late.
GGA runs on every commit, validating staged files against your AGENTS.md. Like having a senior developer review every line before it hits the repo.

- 🔌 Provider agnostic — Claude, Gemini, Codex, OpenCode, Cursor Agent, Kilo, Kiro, Ollama, LM Studio, GitHub Models, MiniMax
- 📦 Pure Bash core — no runtime framework; individual providers may require their own CLI or API tooling
- 🪝 Git native — Standard pre-commit hook
- ⚡ Smart caching — Skip unchanged files
- 🔍 PR review mode — Review full PRs, not just last commit
- 🪟 Cross-platform — macOS, Linux, Windows (Git Bash), WSL
📦 Installation
Homebrew (recommended)
brew install gentleman-programming/tap/gga
Manual
git clone https://github.com/Gentleman-Programming/gentleman-guardian-angel.git
cd gentleman-guardian-angel
./install.sh
Windows (Git Bash, PowerShell, cmd.exe)
git clone https://github.com/Gentleman-Programming/gentleman-guardian-angel.git
cd gentleman-guardian-angel
bash install.sh
echo 'export PATH="$HOME/bin:$PATH"' >> ~/.bashrc && source ~/.bashrc
On Windows, the installer also creates ~/bin/gga.bat so gga can be called from cmd.exe and PowerShell. Add %USERPROFILE%\bin to your Windows user PATH for those shells; .bashrc only affects Git Bash.
WSL is also fully supported — no special configuration needed.
Oh My Zsh users
If you use Oh My Zsh with the git plugin enabled (the default), the alias gga will conflict with this CLI. You'll see:
git: 'gui' is not a git command. See 'git --help'.
Fix: Add this line to your ~/.zshrc after the Oh My Zsh source line:
unalias gga 2>/dev/null
Then run source ~/.zshrc or open a new terminal.
🚀 Quick Start
cd ~/your-project
gga init # Create .gga config
gga install # Install git hook
# Edit .gga to set your PROVIDER
# Create AGENTS.md with your coding standards
# Done — every commit gets reviewed 🎉
