dsh-keymouse-use: Windows Keyboard, Mouse, and Window Automation Tool

The DeepSeek Harness (DSH) plugin `dsh-keymouse-use` is designed to provide low-level control capabilities for automation in Windows environments. It simulates real keyboard and mouse input and performs window management through a helper process, supporting operations such as key combinations, screenshots, window lookup, and window activation. The plugin can be installed locally or via npm, and the client must be restarted after installation for the changes to take effect. Note that it is Windows-only, and coordinates provided by the model are based on physical pixels and require no conversion. The plugin itself does not include visual recognition capabilities; the host environment must provide image recognition support.
