dsh-adrian-agents-group-work

DeepSeek Harness can natively deliver a message only between a parent session and its direct child. Two sibling members have no built-in channel to talk to each other. dsh-adrian-agents-group-work turns a single chat session into a room: a chair agent opens the room, names and spawns a set of member agents, and the plugin carries messages between members through on-disk mailbox files. Everyone shares one task list, and the chair watches the room, nudges silent members, and judges the stop condition. All state lives on disk with atomic write-then-rename, so a process restart or a cold-resumed member rebuilds the room exactly as it was.

Each member receives five room tools (send a message, read the roster, create a task, list tasks, claim or complete a task). The chair gets four additional management tools (open room, pause delivery, resume delivery, close room) plus a debug tool. Delivery is turn-based: no member polls an inbox, and the chair is the only role that can receive a mid-turn message. If a member fails, the plugin writes a notice to the chair mailbox naming the member and the provider error; a third failure within ten minutes also wakes the chair so it can nudge once and then replace the stuck member. Optional progress lines report the last completed tool call of each busy member every thirty seconds, with zero extra model calls.

This plugin suits anyone running DeepSeek Harness 0.1.2-rc.1 or later who needs multiple agents to collaborate on one job: debating a design, voting on options, splitting sub-tasks, or working toward a stop condition such as consensus or majority. It is standalone, declares all six host capabilities (services, commands, subagents, systemPrompt, agents, sessions), and requires no other plugin. Restart the web profile after install and the room tools are ready in every new root session.
