Score: 6.5/10 (Innovation: 5, Technical: 7, Documentation: 8, Utility: 6)

A native Rust TUI replacement for Anthropic's Claude Code terminal interface, built on Ratatui to avoid the memory and performance issues of the original Node.js/React Ink implementation. It's interesting because it provides a drop-in alternative with significantly better resource usage (20-50MB vs 200-400MB) and faster startup while maintaining full compatibility with the official Agent SDK.

Target audience: backend devs, devops, cli power users
