dsh-side-chat

When collaborating with an Agent in DeepSeek Harness, you often need to ask follow-up questions, analyze a selected passage in isolation, or run a parallel workstream without leaving the main conversation. Spawning a new terminal, switching windows, and manually pasting context breaks your flow and risks losing critical details. dsh-side-chat solves exactly this: it embeds a full native DSH session to the right of the main chat, with no custom chat UI and no need to leave the current view.

The side chat is a real DSH Session. Message rendering, tool calls, approval flows, attachments, and model switching are all driven by DSH native components. The main session and side chat share the same workspace, so file edits and command execution produce real side effects, yet their transcripts remain fully independent. When more context is needed, the side_chat_context tool retrieves bounded, relevant parent-session fragments on demand rather than blindly duplicating the entire history. Selecting text in a main message triggers a one-click reference that injects only at send time, leaving no hidden residue in the draft.

It is built for developers who need frequent multi-threaded Agent interaction: a quick side question while debugging a main task, a deeper probe on a specific code passage during review, or validating a subtask in parallel while orchestrating a workflow. The panel can be hidden, preserved, or safely deleted; it coexists mutually exclusively with Better Sidebar; and every interaction stays on the DSH native experience with no custom message renderer or composer.
