bites-the-dsh

In the DeepSeek Harness WebUI, conversations advance linearly. When you need to re-watch a segment for a review call, build a teaching demo, or let a script inspect events turn-by-turn, the only options are manual scrolling or exporting the transcript. Bites the DSH turns the native conversation into an in-place replay timeline: hit Replay session in the session header and the whole thread enters a read-only playback mode, with no side panel required.

During replay, the native composer, model switcher, stop button, branch action, and assistant write actions are all locked while the source session keeps running independently in the background. You can pause, play forward, play in reverse, step event-by-event, adjust playback speed, compress idle gaps, or seek directly to any event, turn, or timestamp. An optional simulated-typing preview shows the next user message in the read-only composer without touching the live draft.

It is built for teams and developers who need session review, demo presentations, or scripted playback control. Bites the DSH exposes a per-session observable controller via ctx.sessionPlayback, so other DSH plugins can subscribe to the clock, control direction and speed, read the current position, and seek by event or turn. The API deliberately exposes no mutation of the source session. All labels in English and Chinese render through DSH theme tokens and sit natively inside ChatView, keeping the visual experience consistent.
