Turn a request into a usable toolDeepSeek showcased Harness Creator Mode on November 2, allowing people to build custom plugins with natural-language requests.

Harness connects models with files, code execution and tools; it is open source and available in public preview worldwide.

Extend both interfaces and actionsPlugins can add tools, skills and interface elements. Users can turn recurring work into a dedicated panel and invoke it within an existing conversation. DeepSeek’s official demo prompt collection includes 3D building displays, poster design, a video-editing workbench and a paper reader. The prompts specify placement, inputs and interactions as well as the desired function.

They describe a plugin and refine the generated result through conversation; DeepSeek notes that some demonstrations required several iterations. Composable plugins give developers and people with recurring workflows a way to adapt the same assistant to their own working environment.
