DeepSeek Harness Plugin: dsh-vision-plugin

The dsh-vision-plugin for DeepSeek Harness resolves the cumbersome issue of manually describing images in multimodal conversations by automatically generating a description of image content before a message is sent and injecting it into the message. The plugin supports uploading or pasting images and uses DashScope vision models or Windows offline OCR to parse them. Users can select an OCR-only or vision-based description mode in the chat box; after a successful description, the system automatically inserts the description at the beginning of the message. The plugin follows a strict routing policy, processes images in memory as base64, and never writes them to disk. This tool simplifies multimodal interaction workflows and is suitable for developers.
