Individual skill
mvvm-toolkit
CommunityToolkit.Mvvm (the MVVM Toolkit) core: source generators ([ObservableProperty], [RelayCommand], [NotifyPropertyChangedFor], [NotifyCanExecuteChangedFor], [NotifyDataErrorInfo]), base classes (ObservableObject / ObservableValidator / ObservableRecipient), commands (RelayCommand / AsyncRelayCommand), and validation. Companion skills: mvvm-toolkit-messenger for pub/sub, mvvm-toolkit-di for Microsoft.Extensions.DependencyInjection wiring. Works across WPF, WinUI 3, MAUI, Uno, and Avalonia.

# CommunityToolkit.Mvvm (core)
Use this skill when authoring or reviewing ViewModels, properties,
commands, or validation in apps that use `CommunityToolkit.Mvvm` 8.x.
> **Companion skills.** Load **`mvvm-toolkit-messenger`** for `IMessenger`
> pub/sub patterns. Load **`mvvm-toolkit-di`** for
> `Microsoft.Extensions.DependencyInjection` integration.
> **Quick recap.** `[ObservableProperty]` on private fields in `partial`
> classes; `[RelayCommand]` on instance methods; inherit from
> `ObservableObject` (or `ObservableValidator` for input forms,
> `ObservableRecipient` when using `IMessenger`).
