Who it is forA developer who is stuck on a bug or codebase question and wants a teammate to join the same Claude session right away.
The problemExplaining a Claude session to a teammate by screenshots or copied text loses context and slows down joint debugging.
The outcomeThe teammate is in the host's session with its shared history, and both people see the same prompts, streamed replies and tool results.
What you need first
- Claude Code 2.1.286 or newer, installed by both the host and each guest
- Your normal Claude authentication
- Git and Node 20+ if you use the setup script or self-host a server
- A Cloudflare account and browser authorization only if you deploy your own Worker
Steps
- In a terminal, run
claude plugin marketplace add Paradigm-Study/claude-share - Run
claude plugin install shared-session@claude-share, then start a new session. - Host: press Share above the prompt or type
/share-session, then copy the link. - Teammate: paste the link into a fresh Claude Code session and send it.
- Either person: ask Claude to read the project README and confirm both sessions show the same reply.
Prompt for your agent
In the Paradigm-Study/claude-share repo, install the shared-session plugin and start a host session that shares a link for the project at <project-path>. Output the share link and confirm the guest session at <guest-session> shows the same prompt and reply. Verify that the guest's prompt ran on the host and the guest's model was not called.
Caveat. Sharing passes the transcript and shared files through the public room server, which is not end to end encrypted, so do not share sessions with secrets.
