Peer-to-peer messaging tool

Key features

• Single peer registrationThe dsh process is registered as a peer (dsh-), Claude Code's ListAgents/SendMessage can directly discover and reply
• Interactive peer_listlists active peers, supports sorting/searching/refreshing
• When receiving a peer message, the injection format comes with a prompt: greetings/confirmation messages do not need to be replied, only reply if there are actual collaboration needs.
• Session identification + internal forwarding: Each session of dsh has an independent short id, the message is marked with @dsh-: identification, Claude replies with the identification, and dsh is forwarded internally to the corresponding session
