Skill instructions
Reactor — Getting Started Prefer the plugin. This file is preserved for environments that don't support the Copilot CLI / Claude plugin loading model. If you have a plugin SDK available, install / load the reactor plugin (under plugins/reactor/ in source, or agentkit/plugins/reactor/ in the NuGet). The plugin splits this content into focused per-skill files and is materially cheaper to load than this monolith. Reactor is a React-inspired functional projection for WinUI 3. You write functions that return lightweight element descriptions; a reconciler diffs old vs new trees and patches real WinUI controls. State changes trigger re-renders automatically. No XAML. No data binding. No ViewModels. Which mode are you in? (read this first) Reactor ships as a NuGet package — apps reference it as <PackageReference Include="Microsoft.UI.Reactor" Version="…" / (or :package Microsoft.UI.Reactor@… for single-file). The package carries the framework, the analyzers, and an agent kit (signatures index
