Joy Hooks

joy

A terminal dashboard for monitoring Claude Code sessions in real-time.

Joy displays all active Claude Code sessions with their current state, project name, and latest message -- like a LINE/Slack unread indicator for your AI coding sessions.

Claude Code Hooks Setup

Install the joy-hooks plugin using the Claude Code CLI:

claude plugin marketplace add https://github.com/yumazak/joy
claude plugin install joy-hooks@joy

That's it! The plugin registers all necessary hooks automatically. Hooks silently do nothing when joy is not running, so no error messages will appear.
