The missing link between Claude Code sessions

Send context, plans, and findings between sessions in real time. Never copy-paste across terminals again.

Pair programming

Send a prompt, pass an interface, share a snippet or a diagram — directly into your partner's session context. They see it at their next prompt. No Slack, no screen share, no "hey can you look at line 42."

Both sessions stay focused on their own work. When one finds something the other needs, /coop sends it through. Claude reads the conversation, composes the message, and your partner's Claude picks it up automatically.

alice — feature-auth
> refactor AuthProvider to use token rotation
Claude Done. New interface:
interface AuthProvider { rotate(token: string): Promise<TokenPair> validate(token: string): boolean revoke(sessionId: string): void }
> /coop pass the new AuthProvider interface to bob
Sent to feature-auth
bob — feature-auth
> wire up the login API route
from @alice
New AuthProvider interface with token rotation — rotate(), validate(), revoke(). Use this for the login route.
Claude Got it. I'll implement the login route using Alice's new AuthProvider interface.

Group work

Generate a plan, split it into sections, and share it with your team. Each person takes a piece and coordinates through their Claude Code session — without ever leaving the shell.

The plan lives in everyone's context. When Alice finishes the API layer, she sends a status update. Bob's Claude sees it and knows the endpoints are ready for the UI. Carol's tests can target the real interfaces, not stubs.

Teleport your session

Working from your desktop? Check the code in, push your context — what you were doing, what's left, what you tried — and pick it up seamlessly on your laptop, a server, or a teammate's machine.

Session context travels with the work, not the hardware. Your plans, findings, and in-progress notes arrive at the next prompt on whatever machine you open next.
