windows-automation is agent-read markdown (skill) from vellum-ai/vellum-assistant: Automate native Windows apps and system interactions with PowerShell, documented COM APIs, and Microsoft UI Automation through the Windows host executor. Use for launching or inspecting desktop apps, opening Windows Settings, controlling scriptable Microsoft Office apps, and interacting with native UI when no direct CLI or API is available..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
