Community Project: claude-duet - real-time shared Claude Code sessions

Hi team,

I built an open-source CLI tool called claude-duet that lets two developers share a Claude Code session in real time.

How it works:

• Host runs Claude Code locally (headless mode via the Agent SDK)
• Partner connects directly via WebRTC peer-to-peer
• Both see Claude's responses streamed live
• All communication is E2E encrypted (NaCl secretbox + scrypt)
• Host can review partner prompts before execution (approval mode)

Use cases:

• Invite a colleague to jump into your session for a quick brainstorm
• Pair program across offices with one shared Claude context
• Demo Claude Code to someone without screen sharing
• Code review with Claude explaining changes live

The guest doesn't need their own API key or Claude account - they just run a join command.

Would love any feedback from the team, and happy to discuss how this could potentially integrate with Claude Code natively.
