Vision Use: Enabling the DeepSeek Harness Agent to See the Screen and Control the Windows Desktop

The Vision Use plugin for DeepSeek Harness (DSH) addresses the issue of agents being unable to directly perceive the desktop environment. By integrating visual channels and system-level operation interfaces, it provides features such as screen capture, mouse movement and clicking, keyboard input, and sending key combinations. It supports both native Windows and WSL2 environments and is easy to install. Once enabled, an agent can control desktop applications using natural-language instructions, such as searching the web or opening Notepad to type text. The plugin is privacy-focused: screenshots are sent only as context and do not generate network requests. Note the compatibility limitations related to Chinese input and some applications, such as Chromium and WinUI.
