ASP.NET Core Web API guides the creation and modification of ASP.NET Core Web API endpoints with correct HTTP semantics, OpenAPI metadata, and error handling. Use it when adding controllers or minimal APIs, defining DTOs, wiring up OpenAPI/Swagger, or configuring global error handling middleware.

Author Blazor Component creates or reviews Blazor components (.razor files) with correct architecture for parameters, EventCallback, RenderFragment slots, lifecycle, async patterns, and disposal. Use it when writing new Blazor components that do not involve JavaScript interop, forms, prerendering, or HTTP data fetching.

Blazor JS Interop provides patterns for adding, reviewing, and fixing JavaScript interop in Blazor components. Use it for collocated .razor.js modules, IJSRuntime lifecycle, DotNetObjectReference callbacks, and batching interop calls.

C# Scripts runs file-based C# apps with the .NET CLI when the user wants C#/.NET code without creating a project. Use for C# language/API experiments, one-file C# apps, and small multi-file C# apps using #:include/#:exclude or #:ref.

Collect User Input builds forms, validates data, and reacts to user input in Blazor apps. Use it for adding forms, search boxes, filter panels, inline editing, data-entry UI, file uploads, and validation with DataAnnotations or custom rules.

Configure Auth adds authentication and authorization to a Blazor Web App, handling render mode interactions. Use it for [Authorize], AuthorizeView, role/policy access, Identity pages, or fixing null auth state after WebAssembly loads.

Configuring OpenTelemetry .NET sets up distributed tracing, metrics, and logging in ASP.NET Core using the .NET OpenTelemetry SDK. Use it when adding observability, configuring OTLP exporters, creating custom metrics or spans, or troubleshooting trace correlation.

Convert Blazor Server to Web App guides migration of a pre-.NET 8 Blazor Server app to the .NET 8+ Blazor Web App model, converting AddServerSideBlazor and MapBlazorHub to AddRazorComponents and MapRazorComponents, replacing _Host.cshtml with App.razor, and adopting interactive server rendering.

Coordinate Components shares state between Blazor components without a direct parent-child relationship, using cascading values, scoped services, or CascadingValueSource. Use it for cascading values across render mode boundaries or app-wide shared data.

Create Blazor Project scaffolds new ASP.NET Core Blazor web apps using dotnet new blazor, guiding choices of render modes (Static SSR, Interactive Server, WebAssembly, Auto) and initial project structure.

Create Custom Agent scaffolds VS Code custom agent files (.agent.md) that define specialized AI personas with tools, instructions, and handoffs. Use it when creating new agents, configuring workflows, or setting up agent-to-agent handoffs.

Create Data-Driven ASP.NET Core generates or scaffolds ASP.NET Core code—Razor Pages, Blazor components, MVC controllers, views, and Minimal API endpoints—without CLI scaffolding tools. Use it to scaffold CRUD pages and API endpoints backed by Entity Framework Core.
