dsh-computer-use-win: Add Windows Desktop Observation and Operation Capabilities to DSH

dsh-computer-use-win is a DSH plugin maintained by Yu-tao-Li, designed to provide computer operation capabilities for Windows desktops to AI agents. Based on the MCP stdio server and the PowerShell/UIA engine, this plugin offers 22 desktop tools to address the needs of agents for reading window structure, executing input, and managing window states. Its core capabilities include visual observation via the UIA accessibility tree and a three-level screenshot chain (PrintWindow, WGC, screen area), supporting control finding and coordinate-based OCR fallback; executing mouse and keyboard operations and window management; and featuring safety mechanisms such as coordinate homing and emergency stop failsafe. Installation requires a Windows system and Node.
