dotnet-cryptography
Modern .NET cryptography covering hashing (SHA-256/384/512), symmetric encryption (AES-GCM), asymmetric cryptography (RSA, ECDSA), key derivation (PBKDF2, Argon2), and post-quantum algorithms (ML-KEM, ML-DSA, SLH-DSA) for .NET 10+. Includes TFM-aware guidance: what's available on net10.0 vs fallback strategies for net8.0/net9.0.
Scope
- Algorithm selection and correct usage of System.Security.Cryptography APIs
- Hashing for integrity (SHA-256/384/512)
- Symmetric encryption (AES-GCM)
- Asymmetric cryptography (RSA, ECDSA)
- Key derivation (PBKDF2, Argon2)
- Post-quantum cryptography (ML-KEM, ML-DSA, SLH-DSA) for .NET 10+
- Deprecated algorithm warnings
Out of scope
- Secrets management and configuration binding -- see [skill:dotnet-secrets-management]
- OWASP vulnerability categories and deprecated security patterns -- see [skill:dotnet-security-owasp]
- Authentication/authorization implementation (JWT, OAuth, Identity) -- see [skill:dotnet-api-security] and [skill:dotnet-blazor-auth]

dotnet-csharp
Baseline C# skill loaded for every .NET code path. Guides language patterns (records, pattern matching, primary constructors, C# 8-15), coding standards, async/await, DI, LINQ, serialization, domain modeling, concurrency, Roslyn analyzers, globalization, native interop (P/Invoke, LibraryImport, ComWrappers), WASM interop (JSImport/JSExport), and type design. Spans 25 topics. Do not use for ASP.NET endpoint architecture, UI framework patterns, or CI/CD guidance.
130dotnet-ui
Builds .NET UI apps across Blazor (Server, WASM, Hybrid, Auto), MAUI (XAML, MVVM, Shell, Native AOT), Uno Platform (MVUX, Extensions, Toolkit), WPF (.NET 8+, Fluent theme), WinUI 3 (Windows App SDK, MSIX, Mica/Acrylic, adaptive layout), and WinForms (high-DPI, dark mode) with JS interop, accessibility (SemanticProperties, ARIA), localization (.resx, RTL), platform bindings (Java.Interop, ObjCRuntime), and framework selection. Spans 20 topic areas. Do not use for backend API design or CI/CD pipelines.
102dotnet-api
Builds ASP.NET Core APIs, EF Core data access, gRPC, SignalR, and backend services with middleware, security (OAuth, JWT, OWASP), resilience, messaging, OpenAPI, .NET Aspire, Semantic Kernel, HybridCache, YARP reverse proxy, output caching, Office documents (Excel, Word, PowerPoint), PDF, and architecture patterns. Spans 32 topic areas. Do not use for UI rendering patterns or CI/CD pipeline authoring.
91dotnet-testing
Defines .NET test strategy and implementation patterns across xUnit v3 (Facts, Theories, fixtures, IAsyncLifetime), integration testing (WebApplicationFactory, Testcontainers), Aspire testing (DistributedApplicationTestingBuilder), snapshot testing (Verify, scrubbing), Playwright E2E browser automation, BenchmarkDotNet microbenchmarks, code coverage (Coverlet), mutation testing (Stryker.NET), UI testing (page objects, selectors), and AOT WASM test compilation. Spans 13 topic areas. Do not use for production API architecture or CI workflow authoring.
87dotnet-advisor
Routes .NET/C# requests to the correct domain skill and loads coding standards as baseline for all code paths. Determines whether the task needs API, UI, testing, devops, tooling, or debugging guidance based on prompt analysis and project signals, then invokes skills in the right order. Always invoked after [skill:using-dotnet] detects .NET intent. Do not use for deep API, UI, testing, devops, tooling, or debugging implementation guidance.
62dotnet-debugging
Debugs Windows and Linux/macOS applications (native, .NET/CLR, mixed-mode) with WinDbg MCP (crash dumps, !analyze, !syncblk, !dlk, !runaway, !dumpheap, !gcroot, BSOD), dotnet-dump, lldb with SOS, createdump, and container diagnostics (Docker, Kubernetes). Hang/deadlock diagnosis, high CPU triage, memory leak investigation, kernel debugging, and dotnet-monitor for production. Spans 17 topic areas. Do not use for routine .NET SDK profiling, benchmark design, or CI test debugging.
