Create Skill Test scaffolds evaluation specs (eval.yaml) for agent skills in the dotnet/skills repository, covering stimuli, graders, rubrics, fixture files, and statistical sizing to avoid overfitting. Use it when creating skill tests or adding evaluation coverage.

Fetch and Send Data covers calling APIs, loading data into Blazor components, and handling the async lifecycle. Use it for registering HttpClient, building service abstractions for Auto/WebAssembly render modes, and displaying loading and error states.

Improve Skill Quality diagnoses failing or unconvincing skill evaluations and turns them into targeted fixes. Use it when an evaluation verdict is a regression, underpowered, or returns no credible improvement, or when deciding whether to strengthen or retire a weak skill.

Minimal API File Upload implements file upload endpoints in ASP.NET Core minimal APIs using IFormFile and IFormFileCollection, covering size limits, content validation, and anti-forgery handling. Use it when building .NET 8+ APIs that accept multipart/form-data uploads.

.NET P/Invoke correctly calls native C/C++ libraries from .NET using DllImport and LibraryImport, covering signatures, strings, memory, SafeHandle, and cross-platform patterns. Use it for writing, reviewing, or debugging native interop code in .NET.

NuGet Trusted Publishing sets up NuGet trusted publishing (OIDC) on GitHub Actions to replace long-lived API keys with short-lived tokens. Use when migrating from secrets.NUGET_API_KEY, setting up keyless or secure NuGet publishing, or creating a new NuGet publish workflow.

Optimizing EF Core Queries diagnoses and fixes slow Entity Framework Core queries by reducing generated SQL, database round-trips, and per-call translation cost. Use it when an EF Core query or data-access path is slow, emits N+1 statements, or pays LINQ translation overhead on every call.

Plan UI Change decomposes complex Blazor UI features into focused, composable components with parent-child data flow, then immediately implements them bottom-up. Use it when building multi-section pages, dashboards, or any Blazor UI with three or more distinct visual sections.

Skill Scaffolder creates new agent skills that conform to the Agent Skills specification and dotnet/skills conventions, generating SKILL.md frontmatter, section templates, and validation guidance. Use it when setting up a new skill directory or writing a description that the runtime will route to.

Support Prerendering makes interactive Blazor components work correctly when prerendered, fixing duplicate data loads, UI flicker, null references during prerender, and state persistence across the handoff. Use it when prerendering causes issues in Server, WebAssembly, or Auto render mode apps.

Technology Selection helps developers choose the right .NET AI/ML stack (ML.NET, Microsoft.Extensions.AI, Microsoft Agent Framework, ONNX Runtime, OllamaSharp) for classification, LLM integration, RAG, agentic workflows, and local inference in .NET 8+ projects.

Workflow Authoring teaches how to write GitHub Actions workflow YAML that is syntactically valid for GitHub Actions, not just YAML. Use it when editing or reviewing .github/workflows files, writing expressions with ${{ }}, quoting scalars, or diagnosing workflow file issues with actionlint.
