winui-code-review skillA

winui-code-review is agent-read markdown (skill) from microsoft/win-dev-skills: Code quality review for WinUI 3 apps — MVVM compliance, x:Bind correctness, accessibility, theming, security, and performance. Use before committing to catch issues that the compiler and UI tests won't find..

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.

What the file says

### When to Use

Run a code review **after the app builds and before committing**. This catches quality issues that aren't build errors and aren't visible in UI tests — patterns that compile and run but are wrong, fragile, or slow.

### How to Review

Read through the project's XAML and C# files and check each section below. The `Microsoft.WindowsAppSDK.Analyzers` Roslyn analyzer ships with the `winui-dev-workflow` skill and is injected when `BuildAndRun.ps1` calls project-mode `winapp run`. The wrapper supplies a temporary file through the environment-backed MSBuild `CustomAfterDirectoryBuildProps` hook, preserving SDK composition and each project's normal `Directory.Build.props` discovery (including referenced projects), then restores the environment and removes the temporary file. Plain `winapp run`, `dotnet build`, and Visual Studio do **not** load the analyzer automatically; to enable it outside the wrapper, add the `<Analyzer Include="..." />` and `<Import Project="..." />` entries to the project's own `Directory.Build.props` (or wait for the planned NuGet package).

The analyzer catches a curated set of WinUI 3 / Windows App SDK issues with categorized 4-digit IDs:
