About this skill

Message other Claude sessions by name, and spawn/coordinate detached background Claude agents. Use when the user asks to talk to another Claude, have two sessions message each other, delegate work to a worker/sub agent, run several Claudes in parallel, build a team of agents, or check on / reply to a running agent. Register a name, then send and receive messages by name; incoming messages are delivered to you automatically.
