winui-code-review

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.

winui-design

Use when designing, reviewing, or fixing WinUI 3: layout planning, control choice, Fluent Design alignment, Light/Dark/High Contrast theming, typography, spacing, brushes, accessibility, and XAML data-binding design. Load before authoring new XAML, reviewing UI PRs, migrating desktop UI to WinUI, or choosing between WinUI controls/patterns.

winui-dev-workflow

Build and run workflow for WinUI 3 apps — project creation, BuildAndRun.ps1 script, winapp run, error diagnosis, and prerequisites. Use when building, running, or fixing build errors in a WinUI 3 project.

winui-packaging

MSIX packaging, code signing, and distribution for WinUI 3 apps — build for release, certificate generation (winapp cert generate), certificate trust, code signing (winapp sign), self-contained deployment, CI/CD with GitHub Actions, and Microsoft Store submission. Use when preparing for release, creating MSIX installers, managing certificates, setting up CI/CD packaging, or publishing to the Microsoft Store.

winui-session-report

Analyze the current or a recent agent session (GitHub Copilot CLI or Claude Code) and generate a diagnostic report. Use when asking for session feedback, debugging agent behavior, or reviewing what happened during a build session.

winui-setup

Install and verify the prerequisites the win-dev-skills WinUI 3 toolchain depends on — .NET SDK 10, the WinApp CLI, the WinUI 3 .NET templates, and Developer Mode. Use when setting up a new machine, after a Windows reset, or when another winui skill reports a missing prerequisite (e.g., `winapp` not found, `dotnet` not found, the WinUI 3 templates are missing, or Developer Mode is off).

winui-ui-testing

Automated UI testing for Windows desktop apps — generate a batch test script with the `winapp ui` UI Automation harness, run all tests in one pass, read results. Covers element assertions, interactions, value checking (TextBox, ComboBox, ToggleSwitch), keyboard shortcuts and typing (send-keys), hover, drag-and-drop, touch and pen input, file pickers, flyouts, dialogs, persistence, accessibility audits, and screenshot/video capture. Works on any Windows app (Win32, WPF, WinForms, WinUI 3, packaged or unpackaged).

winui-wpf-migration

Migrate WPF applications to WinUI 3 — namespace replacement (System.Windows → Microsoft.UI.Xaml), control mapping (DataGrid→ListView, WrapPanel→ItemsRepeater, TabControl→TabView), threading (Dispatcher→DispatcherQueue), imaging (System.Drawing→BitmapImage), MVVM conversion to CommunityToolkit.Mvvm, and DynamicResource→ThemeResource. Use when converting WPF code, replacing WPF namespaces, or fixing migration build errors.
