Claude Code sessions can now message each other
Two open sessions can talk: Claude finds the others with ListAgents and sends a message through SendMessage, either because you asked or on its own when a change in one session affects the work in another. Only text Claude writes crosses over — never conversation history, never files. Since version 2.1.232 you can also address a session directly by typing @ followed by its name. The feature runs on macOS and Linux and needs version 2.1.224 or later, and /list-agents shows what is available. It pays off most when you keep the frontend and backend of the same project in separate sessions.
