xby-seg: An Instance Segmentation Plugin for DeepSeek Harness

xby-seg is a plugin for DeepSeek Harness (DSH) that provides YOLO26-based instance segmentation capabilities for model inference. It can accurately segment objects in images and output information such as bounding boxes and masks. The plugin supports configuring a persistent API key and offers three segmentation interfaces corresponding to image URLs, BASE64-encoded data, and file paths, respectively. The installation command is `dsh plugin --profile web add github:xby_skill/xby-seg`. Users must obtain a key from the official Xiaobenyang website before using it. The plugin is provided under the MIT license and depends on external API services.
