dsh-vision-resident: DeepSeek Harness Resident Vision Subagent

`dsh-vision-resident` is a resident vision plugin for DeepSeek Harness, designed to address the limitation of purely text-based main models that cannot process images directly. By mounting hooks, it enables the main model to “see” images without launching independent subagents, significantly reducing overhead. The plugin supports zero-subagent reasoning, persistent conversational memory, session-isolated history, and durable storage. Users can read local images through tools, allow the main model to automatically interpret images, and view recognition history via the interface. Installation requires manually mounting the code, offers flexible configuration, and supports custom vision models. Despite known limitations such as model-switching constraints, it provides a lightweight and efficient solution for scenarios with frequent visual tasks.
