- Tool-enabled critiques. Can search the web, inspect the codebase and make tool calls during reviews.
- Terminal UI. Provides an interactive Ink-based interface that runs alongside Claude Code.
- Hooks integration. Automatically configures Claude Code hooks to monitor session events and trigger reviews.
