What the dsh-smooth-stream DSH plugin can do

  • Text appears at the rate it arrives, avoiding sudden bursts or pauses.
  • Markdown elements like code and emphasis render inline during streaming, no raw-to-formatted transition.
  • New lines and tool cards slide into view instead of jumping the entire page.
  • Scroll position is controlled by the user; auto-following only engages when scrolled to the bottom.
  • Supports prefers-reduced-motion: disables smooth effects and auto-following when enabled.
  • Pauses rendering when frame rate drops below 30 fps and the reply is off-screen, resumes when conditions improve.

Where the dsh-smooth-stream DSH plugin fits

  • Reading long model responses in DeepSeek Harness Web UI with a natural, flicker-free flow.
  • Maintaining scroll context when the model outputs multiple lines or tool calls simultaneously.
  • Ensuring accessibility for users who prefer reduced motion by automatically falling back to plain output.
  • Improving the visual experience when network latency causes irregular token arrival.

Who the dsh-smooth-stream DSH plugin is for

  • DeepSeek Harness users who interact with the Web UI and want a smoother reading experience.
  • Developers deploying DeepSeek Harness with the web profile who want to customize the streaming output behavior.

dsh-smooth-stream DSH plugin limitations

  • Only works with DeepSeek Harness's Web UI profile (requires `--profile web` during installation).
  • Requires the DeepSeek Harness source code or a local environment where the `dsh` CLI is available.
  • Performance-dependent: smooth rendering may pause if frame rate drops below 30 fps and reply is off-screen.
  • Not an official DeepSeek plugin; community-maintained under MIT license.
