dsh-session-collaboration

DeepSeek Harness sessions lack a native channel for collaboration. When juggling multiple concurrent tasks, users often have to manually copy context between windows, breaking flow and risking lost information. dsh-session-collaboration addresses this by letting agent sessions explicitly relay context to each other in both directions, without human intermediation.

At its core, the plugin wires together a session_delegate model tool, an Agent.steer()-based runtime, and a Web jump card into a single collaboration pipeline. Once the model calls session_delegate, the message is admitted through the target session's next-step steering path and appears to the target as inserted model context rather than a new human input, so the caller never has to retype the task in another box. The tool supports synchronous reply-waiting with automatic relay back, as well as one-way delivery. On the Web profile, a "Jump to target session" card switches the current view in one click.

This is built for developers orchestrating complex multi-session workflows, particularly in multi-workspace or multi-agent parallel pipelines. The bundle mounts as an independent patch layer, requires no edits to existing user patches, and disables cross-workspace delivery by default, striking a balance between flexibility and safety.
