Winmd Api Search

This is a smart Windows API discovery tool that searches through cached WinMD metadata to find the right APIs for any desktop capability. Instead of hunting through documentation when you need camera access, file pickers, or UI controls, you search with plain English terms like "take picture" or "save settings" and get back ranked results with full type signatures, methods, and enum values. It indexes the Windows Platform SDK, WinAppSDK, and any NuGet packages in your projects. The search scoring is well-tuned, handling exact matches, partial matches, and even PascalCase initials. Beats manually digging through Microsoft Learn when you just need to know what methods are available on a specific type.

WinMD API Search

This skill helps you find the right Windows API for any capability and get its full details. It searches a local cache of all WinMD metadata from:

Windows Platform SDK — all Windows.* WinRT APIs (always available, no restore needed)
WinAppSDK / WinUI — bundled as a baseline in the cache generator (always available, no restore needed)
NuGet packages — any additional packages in restored projects that contain .winmd files
Project-output WinMD — class libraries (C++/WinRT, C#) that produce .winmd as build output

Even on a fresh clone with no restore or build, you still get full Platform SDK + WinAppSDK coverage.

When to Use This Skill

User wants to build a feature and you need to find which API provides that capability
User asks "how do I do X?" where X involves a platform feature (camera, files, notifications, sensors, AI, etc.)
You need the exact methods, properties, events, or enumeration values of a type before writing code
You're unsure which control, class, or interface to use for a UI or system task
