Winui Code Review

This is a pre-commit checklist for WinUI 3 projects that catches the patterns compilers miss. It walks through MVVM compliance (are you using ObservableProperty correctly, do you have UI types in your ViewModels), x:Bind gotchas (Mode not set, missing x:DataType on DataTemplates), accessibility gaps (AutomationId on interactive controls), theming mistakes (hardcoded colors instead of ThemeResource), and performance traps (blocking the UI thread, non-virtualized lists). It pairs with a Roslyn analyzer that ships diagnostic codes for migration issues and runtime pitfalls, though the analyzer integration requires a build script from another skill. Run this after the build passes but before you push, when automated tests won't catch fragile or slow code that technically works.
