dsh-vision-provider: Selecting Vision Model Combinations in the DeepSeek Harness Web UI

dsh-vision-provider is a community plugin for DeepSeek Harness (DSH), designed to enable a dual-model bridge of "vision model analysis + DeepSeek reasoning responses." Rather than native pixel input, it exposes third-party vision models declared with image input capability in Settings as an optional combination. When a user sends an image-containing request, the selected vision model processes the image, and the result replaces the original image before being handed over to DeepSeek for reasoning, tool invocation, and final responses; plain-text requests are handled directly by DeepSeek. The plugin supports configuring third-party vision models via the Web UI or directly connecting to OpenAI-compatible endpoints. Installation requires Node.js >=22.19.0 and a compatible DSH version.
