Optimizes agent context setup for .NET/C# projects. Use when starting a new session, when agent output quality degrades (wrong patterns, hallucinated APIs, unaware of .NET conventions), when switching between Avalonia/Blazor/ASP.NET Core codebases, or when you need to configure CLAUDE.md, .editorconfig, and analyzer…

Skill Claude CodeCodex
Guides systematic root-cause debugging for .NET/C# code. Use when dotnet test fails, dotnet build breaks, behavior doesn't match expectations, or you encounter any unexpected error (NullReferenceException, TaskCanceledException, missing DI registration, EF Core migration conflict). Use when you need a systematic…

Skill Claude CodeCodex
Subjects every non-trivial decision to a fresh-context adversarial review before it stands. Use when correctness matters more than speed, when working in unfamiliar code, when stakes are high (production, security-sensitive logic, irreversible operations like EF Core migrations or deploys), or any time a confident…

Structures git workflow practices for .NET/C# projects — atomic commits, trunk-based branches, pre-commit hygiene with dotnet test + dotnet format, worktrees for parallel agent work. Use when making any code change to a .NET solution, when committing, branching, resolving conflicts, or organizing work across multiple…

Skill Claude CodeCodex
Refines raw ideas into sharp, actionable .NET/C# concepts through structured divergent and convergent thinking. Use "idea-refine" or "ideate" to trigger when deciding what to build next in a .NET solution — new Avalonia app, ASP.NET Core API, EF Core data model, NuGet library, or process improvement.

Skill Claude CodeCodex
Delivers .NET/C# changes incrementally — thin vertical slices with dotnet build + dotnet test verification between each. Use when implementing any feature that touches more than one project or assembly. Use when you're about to write a large amount of code at once, or when a task feels too big to land in one step.

Tests .NET/C# systems at their integration boundaries — HTTP APIs with WebApplicationFactory , EF Core against real databases via Testcontainers (PostgreSQL, SQL Server, Redis), Blazor/Razor Pages in real browsers via Microsoft.Playwright, Avalonia UI via Avalonia.Headless.XUnit. Works with xUnit v2/v3 on VSTest or…

Extracts what the user actually wants instead of what they think they should want. Achieves this through one-question-at-a-time interview until 95% confidence about the underlying intent. Use when an ask is underspecified ("build me X" without "for whom" or "why now"), when the user explicitly invokes ("interview me"…

Instruments .NET/C# code so production behavior is visible and diagnosable. Use when adding logging, metrics, tracing, or alerting to an ASP.NET Core / Blazor / worker / desktop app. Use when shipping any feature that runs in production and you need evidence it works. Use when production issues are reported but you…

Optimizes .NET/C# application performance — measure first with BenchmarkDotNet / dotnet-counters / dotnet-trace / PerfView, then fix the specific bottleneck (EF Core N+1, sync-over-async, Gen2 GC pressure, thread-pool starvation, allocation hotspots, unbounded queries, missing pagination, Kestrel misconfiguration).…

Skill Claude CodeCodex
Breaks .NET/C# work into ordered, verifiable tasks. Use when you have a spec or clear requirements and need to decompose work into implementable units with dotnet CLI verification steps. Use when a task feels too large to start, when you need to estimate scope across a multi-project solution, or when parallel work is…

Creates specs before coding a .NET/C# project. Use when starting a new .NET 8+ solution, feature, or significant change and no specification exists yet. Use when requirements are unclear, ambiguous, or only exist as a vague idea. Frames examples for Avalonia, ASP.NET Core, Blazor, .NET MAUI, EF Core, xUnit, and MSTest.
