Entity Framework Core patterns for .NET 10. Covers DbContext configuration, migrations workflow, interceptors, compiled queries, ExecuteUpdateAsync, ExecuteDeleteAsync, value converters, and query optimization. Load this skill when working with databases, writing queries, managing schema changes, or when the user mentions "EF Core", "Entity Framework", "DbContext", "migration", "LINQ query", "database", "SQL", "N+1", "Include", "split query", "value converter", "interceptor", or "compiled query".
Architecture selection advisor for .NET applications. Asks structured questions about domain complexity, team size, system lifetime, compliance, and integration needs, then recommends the best-fit architecture: Vertical Slice, Clean Architecture, DDD + Clean Architecture, or Modular Monolith. Load this skill when the user asks "which architecture", "choose architecture", "set up project", "new project", "architecture decision", "restructure", or "how should I organize". Always load BEFORE any architecture-specific skill.
Asynchronous messaging patterns for .NET applications. Covers Wolverine and MassTransit, outbox pattern, saga and choreography, and broker configuration for RabbitMQ and Azure Service Bus. Load this skill when implementing event-driven communication, background processing, module-to-module messaging, or when the user mentions "Wolverine", "MassTransit", "message bus", "RabbitMQ", "Azure Service Bus", "event", "publish", "consumer", "outbox", "saga", "integration event", "queue", or "pub/sub".
Dependency health report for .NET solutions: outdated NuGet packages, vulnerable versions, and commercial-license traps (MediatR, MassTransit, FluentAssertions, AutoMapper) — powered by the get_nuget_packages MCP tool. Invoke when: "outdated packages", "check dependencies", "stale packages", "package audit", "dependency health", "are my packages up to date", "license check", "vulnerable packages", "nuget audit".
Domain-Driven Design tactical patterns for .NET applications. Covers aggregates, aggregate roots, value objects, domain events, domain services, strongly-typed IDs, and repository patterns for aggregate persistence. Load this skill when implementing DDD, working with aggregates, value objects, domain events, bounded contexts, or when the architecture-advisor recommends DDD + Clean Architecture. Pair with the clean-architecture skill.
Convert .NET test projects from xUnit.net v2 or v3 to MSTest v4. Use for replacing xunit packages, [Fact]/[Theory], xUnit assertions, fixtures, ITestOutputHelper, traits, skips, and xUnit parallelization with MSTest equivalents while preserving the current VSTest or MTP runner. DO NOT USE FOR: xUnit v2 to v3 upgrades, MSTest version upgrades, migrations from NUnit/TUnit, or runner-only VSTest to MTP migrations.
OpenTelemetry observability for .NET 10 applications. Covers traces, metrics, and logs using the OpenTelemetry SDK with OTLP export. Includes custom ActivitySource, IMeterFactory metrics, resource configuration, and Aspire Dashboard integration. Load this skill when setting up distributed tracing, custom metrics, OTLP export, or when the user mentions "OpenTelemetry", "OTLP", "traces", "spans", "Activity", "ActivitySource", "metrics", "IMeterFactory", "Meter", "Counter", "Histogram", "Gauge", "telemetry", "observability", "distributed tracing", "OTEL", or "Aspire Dashboard".
Observability overview and glue for .NET 10: how the pieces fit together, plus the cross-cutting parts owned here — ASP.NET health check endpoints (/health), correlation IDs, and log-level strategy. For deep Serilog setup load `serilog`; for traces and metrics load `opentelemetry`. Load this skill when setting up observability from scratch, wiring health check endpoints or correlation IDs, or when the user says "logging", "observability", "monitoring setup", "liveness", "readiness", or "ILogger".
CI/CD pipelines for .NET applications. Covers GitHub Actions and Azure DevOps YAML pipelines with build, test, publish, and deploy stages. Load this skill when setting up continuous integration, automated testing, deployment workflows, or when the user mentions "CI/CD", "pipeline", "GitHub Actions", "Azure DevOps", "workflow", "deploy", "build pipeline", "publish", "NuGet push", "release", or "continuous integration".
Structured logging with Serilog for .NET 10 applications. Covers two-stage bootstrap, appsettings configuration, enrichers, sinks, request logging, destructuring, and Serilog.Expressions. Load this skill when setting up Serilog, configuring log sinks, enrichers, or structured logging, or when the user mentions "Serilog", "structured logging", "log enrichment", "Seq", "LogContext", "UseSerilog", "WriteTo", "message template", "Serilog.Expressions", "request logging", "log sink", "rolling file", or "audit log".
Run a comprehensive 7-phase verification pipeline for .NET projects: build, analyzers, antipattern detection, tests, security, formatting, and diff review. Each phase produces PASS/FAIL with actionable output and the pipeline short-circuits on critical failures. Also the authority on verification strategy: which phases to run for a given change, quality gates, and fix-and-retry loops. Use when: "verify", "check everything", "is this ready", "pre-PR check", "run all checks", "quality gate", "verification strategy", "which checks should run", or after completing a feature or refactor.
Dependency injection patterns for .NET 10. Covers service lifetimes, keyed services, the decorator pattern, factory pattern, and common DI pitfalls. Load this skill when registering services, resolving lifetime issues, designing service composition, or when the user mentions "DI", "dependency injection", "service registration", "AddScoped", "AddTransient", "AddSingleton", "keyed services", "decorator", "Scrutor", "IServiceCollection", or "captive dependency".
