Feature request: real-time multi-user collaboration on a single Claude Code session

Summary

There is currently no way for two different user accounts to share and collaborate on a single Claude Code session in real time (think Google Docs / VS Code Live Share, but for a Claude Code chat).

Current state (as I understand it)

• "Share" links from claude.ai are read-only views, not collaborative.
• "Teammates" and "peer sessions" all belong to the same account — different devices/processes, not different humans.
• Remote Control lets you drive your session from another device, but again — single user.
• The only workarounds are screen sharing (one person types) or tmux session sharing (not officially supported).

Use cases this would unlock

• Pair programming with a colleague where both can prompt the same agent.
• Mentoring / onboarding: a senior dev watches a junior's session live and can intervene.
• Live code review where reviewer and author both interact with Claude in the same context.
• Async handoff where a teammate picks up exactly where you left off (richer than a shared transcript).

Possible shapes

• A "Share session" action on claude.ai/code that grants edit access to another Anthropic account (with permission scopes: view / suggest / write).
• An equivalent of isolatePeerMachines extended to cross-account peers (with explicit per-message approval).
• Read-write share links with expiry, similar to Figma/Notion.

Why it matters

Claude Code is increasingly used inside teams, but the paradigm is still "single user + agentic delegation." For software work that is fundamentally collaborative, this is a gap that pushes teams to clunkier workarounds (screen sharing, copy-pasting transcripts).

Thanks for considering!
