BobNet

Enables multiple Claude Code sessions on the same machine to discover each other and exchange messages via a shared local bus.

Uses a two-tier architecture where each Claude Code session runs a short-lived stdio client connecting to a singleton long-lived daemon that routes messages via Unix sockets. Sessions register with names and advertise their expertise, supporting directed and broadcast messaging, status updates, and join/leave event notifications. OS-enforced same-user-only access with no network exposure.
