dsh-side-chat

When the main conversation is running a complex multi-step workflow, you often need to ask a quick question, verify a variable, or run a command without interrupting the agent or manually copying context into another window. DSH Side Chat solves exactly this: a truly independent native DSH session opens alongside the main chat. It is not a floating panel nor a hand-built chat UI, but a full DSH Session where two threads proceed in parallel.

Both sessions share the same workspace, so file modifications and tool side-effects are real, yet their transcripts remain fully independent. The side chat never auto-copies the entire main conversation. It presents the complete native interface: model picker, attachments, tool invocations, and approval flows all work out of the box. Select text in any main message to quote it into the side chat; the reference is injected only at send-time and leaves no residue in the composer. When the side chat genuinely needs more context, it retrieves bounded, relevant fragments from the parent session via the side_chat_context tool rather than duplicating the full history.

Ideal for DeepSeek Harness users running long tasks, multi-step reasoning, or workflow orchestration. If you frequently want to step aside and ask a question while the agent is mid-execution, or prefer to compare two approaches side by side without cross-contamination, this plugin is built for that workflow.
