ruby-oop

Two commands. That's it.

```bash

# 1. Install the CLI

curl -fsSL https://han.guru/install.sh | bash

# 2. Auto-detect and install plugins for your project

han plugin install --auto

```

Next time you use Claude Code, validation hooks run automatically when you finish a conversation.

Alternative Installation

```bash

# Homebrew (macOS/Linux)

brew install thebushidocollective/tap/han

```

1. Install - One command installs the CLI and auto-detects plugins for your stack
2. Code - Claude writes code as usual. No workflow changes needed
3. Validate - Stop hooks run automatically. Linters, formatters, type checkers, and tests are all verified
4. Learn - Local metrics track success rates and calibrate confidence. Nothing leaves your machine
