dsh-session-collaboration

DeepSeek Harness sessions have no built-in way to collaborate with one another. When running multiple concurrent agent tasks, users tend to copy context by hand between windows, which breaks focus and risks losing information. dsh-session-collaboration fills that gap by enabling explicit, bidirectional context relaying between sessions with no human in the loop.

The plugin integrates a session_delegate model tool, an Agent.steer()-backed relay runtime, and a Web jump card into a single collaboration pipeline. When the model invokes session_delegate, the payload is admitted through the target session's next-step steering path, so the target perceives it as inserted model context rather than a fresh human input. The caller does not need to retype the task in another prompt box. The tool supports synchronous reply-waiting with an automatic return relay, as well as one-way or reverse delivery when the other side is already waiting. In the Web profile, a "Jump to target session" card lets the user switch the current view with a single click.

This bundle is aimed at developers who coordinate multi-session or multi-agent workflows, especially in parallel pipelines across working directories. It mounts as a standalone patch layer, leaves existing user patches untouched, and keeps cross-workspace delivery disabled by default, offering a pragmatic balance between flexibility and operational safety.
