dsh-chat-link

DSH's built-in multi-agent collaboration is confined to parent-child subagent hierarchies within a single session; there has been no peer-to-peer channel between separate sessions. dsh-chat-link closes that gap: any two sessions can now converse like an instant-messaging pair, removing the need for a human relay or repeated context copy-paste.

Type @ in any input box to open a native session picker; the chosen target appears as a blue chip tag. On send, the target session is woken immediately and treats the message as a task; when it replies, the source session is woken in turn, creating a true two-way dialogue. If the target is offline, messages persist to a local message board with a three-second polling fallback, surviving DSH restarts. A sidebar inbox panel follows the DSH design system, shows live unread badges, and lets you jump directly to any message or conversation. Five agent tools (chat_link_send, chat_link_inbox, chat_link_history, chat_link_roster, chat_link_register) let every session query and dispatch cross-session messages mid-reasoning, and link names stay in sync with session titles in real time.

Ideal for DSH users running multiple workflow sessions that need frequent context exchange: one session writes code, another does research, and a simple @ keeps them in sync. All data remains local with no cloud dependency and no telemetry.
