About this plugin
When you run multiple DSH sessions on the same host, they are isolated islands: no way to pass a message, no way to wake a dormant peer. dsh-s2s uses an in-process broker so sessions can address each other by name (title) and also resume a session that has gone idle. The whole path is zero-port, zero-WebSocket, zero network overhead.
Unlike cross-host a2a, s2s stays single-process on one host and borrows only the injection idioms (followup when idle, inject when busy). All delivery is direct in-memory. Six model tools cover discovery, messaging, history, and scheduled wake-up; mailboxes persist locally with atomic writes and self-healing; the sender side has built-in hop limits and rate control to prevent loops.
If you run several role-based sessions (dev, product, QA, etc.) on one machine and want them to collaborate like colleagues, picking each other by name and waking dormant peers without a hub or an open port, s2s is built for that.
Use Cases
- Dev session pings the product session by name to confirm a requirement before coding
- Schedule a dormant QA session to run regression tests on a timer and report back
- Multiple role-based sessions chain together to deliver a full project on one machine
Best For
- Users running multiple DSH sessions on a single host
- Developers who want multi-role AI collaboration without a hub or open ports
- Agent-workflow practitioners who need inter-session messaging and on-demand wake-up
