DeepSeek Harness Plugin: dsh-vdesktop

The DeepSeek Harness plugin `dsh-vdesktop` uses the Windows API to create an invisible virtual desktop, enabling LLM agents to interact with GUI applications. Through an HTTP frame-capture service and a JSON-RPC toolchain, it supports 12 desktop operations, screenshots, mouse and keyboard control, and file access. It features full lifecycle management, semantically accurate clicking, process supervision, and a web-based visualization panel, allowing agents to run applications in an isolated environment while supporting human takeover. Installation requires configuring the Sidecar path and handling asynchronous startup logic, aiming to bridge the gap between command-line agents and graphical interfaces.
