Skill instructions
Async Resources in Reactor Reactor replaces the UseState + UseEffect + manual-cancellation dance with three hooks. Reads return AsyncValue<T, writes return a Mutation handle. The hook owns the cancellation token, dedups across siblings, caches results in a shared QueryCache, and drops late results on unmount. Available on any Component subclass directly; on RenderContext as extension methods for function components (Memo(ctx = ...) or RenderEachTime(ctx = ...)). 1. UseResource — single fetch csharp AsyncValue<T UseResource<T( Func<CancellationToken, Task<T fetcher, object[] deps, ResourceOptions? options = null); AsyncValue<T is a sealed 4-state record: Loading, Data(T Value), Error(Exception), Reloading(T Previous) (stale-while-revalidate). Pattern-match with a switch: csharp class UserCard : Component { public override Element Render() { var user = UseResource( ct = Api.GetUserAsync(userId, ct), deps: new object[] { userId }); return user switch { AsyncValue<User.Loading = TextBlock(
