Coding & Dev Tools

dotnet Bundle

Generates personalized greetings based on the time of day and the person's name.

dotnet Bundle

Guides developers through capturing diagnostic artifacts to diagnose production .NET performance issues, including tool selection and data collection across Windows, Linux, containers, and Kubernetes.

dotnet Skill

Add the /bl switch to MSBuild-based commands to generate binary logs for build diagnostics and performance analysis.

dotnet Skill

Optimize MSBuild build parallelism by configuring /maxcpucount, graph build mode, project references, and analyzing binlogs to reduce multi-project solution build times.

dotnet Skill

Diagnose and fix slow MSBuild incremental builds by identifying why targets re-execute unnecessarily, covering common causes like missing Inputs/Outputs, volatile properties, and FileWrites registration.

dotnet Skill

Provides canonical MSBuild property definition patterns including conditional defaults, composition, path normalization, target framework detection, and evaluation order for diagnosing and fixing property issues in .props and .csproj files.

dotnet Bundle

Audits test code in any language using the academic testsmells.org 19-smell catalog, producing a severity-ranked report with specific locations and actionable fixes.

dotnet Skill

Write, create, modernize, or fix comprehensive MSTest unit tests with MSTest 3.x/4.x APIs, covering assertions, data-driven tests, lifecycle, and async patterns.

dotnet Bundle

Resolve IL trim and AOT analyzer warnings in .NET projects to make them compatible with Native AOT and trimming.

dotnet Skill

Call APIs, load data into components, and handle the async lifecycle in Blazor.

dotnet Bundle

Implement Shell-based navigation in .NET MAUI apps, including AppShell setup, URI-based navigation with GoToAsync, route registration, query parameters, flyout and tab configuration, and navigation guards.

dotnet Bundle

Parse source files to find which ones have no test file referencing their declared types, producing a prioritized worklist of untested files.

dotnet Skill

Fix interactive Blazor components that break during prerender: duplicate data loads, null references, UI flicker, and state loss. Persist state across the prerender-to-interactive handoff, disable prerendering, exclude pages from interactive routing, and detect prerender vs interactive at runtime.

dotnet Skill

Measure and optimize .NET build performance by establishing baselines, enabling MSBuild Server, using artifacts output, and trimming dependency graphs.

dotnet Skill

Detects MSBuild projects with conflicting OutputPath or IntermediateOutputPath to diagnose build failures.

dotnet Bundle

Scaffolds new Blazor web applications with the correct render mode, project structure, and authentication setup.

dotnet Bundle

Detects and fixes common MSBuild anti-patterns in .csproj, .vbproj, .fsproj, .props, .targets, and .proj files, covering Exec misuse, unquoted conditions, hardcoded paths, and more.

dotnet Bundle

Provides file paths to language-specific extension files for the code-testing pipeline, enabling discovery of guidance for .NET, Python, TypeScript, and other languages.

dotnet Bundle

Analyzes .NET Framework CLR activation logs to diagnose runtime loading failures, version selection issues, and Feature-on-Demand dialog behavior.

dotnet Skill

Migrate legacy MSBuild project files to SDK-style format, reducing .csproj complexity and enabling modern .NET features.

dotnet Bundle

Provides file paths to language-specific reference files for polyglot test analysis skills, enabling framework-aware detection of test markers, assertions, and patterns across .NET, Python, TypeScript, Java, Go, Ruby, Rust, Swift, Kotlin, PowerShell, and C++.

dotnet Bundle

Symbolicate .NET runtime frames in Apple platform .ips crash logs by extracting UUIDs and addresses, locating dSYM debug symbols, and running atos to produce function names with source file and line numbers.

dotnet Bundle

Configure dependency injection in .NET MAUI apps — service registration in MauiProgram.cs, lifetime selection, constructor injection, Shell navigation auto-resolution, platform-specific registrations, and testability patterns.

dotnet Skill

Mechanically replace static dependency call sites with wrapper or built-in abstraction calls across a bounded scope, such as migrating DateTime.UtcNow to TimeProvider.GetUtcNow() or File.ReadAllText to IFileSystem.

dotnet Skill

Migrates .NET Framework code using Thread.Abort to cooperative cancellation with CancellationToken in modern .NET 6+.

dotnet Skill

Optimize Entity Framework Core queries by fixing N+1 problems, choosing correct tracking modes, using compiled queries, and avoiding common performance traps.

dotnet Skill

Diagnose MSBuild build failures by analyzing .binlog files using an MCP server or text-log replay.

dotnet Skill

Scan C# source files for hard-to-test static dependencies and produce a ranked report of static call sites by frequency.

dotnet Bundle

Scans C#/.NET code for ~50 performance anti-patterns across async, memory, strings, collections, LINQ, regex, serialization, and I/O with tiered severity classification.

dotnet Skill

Guides creation and validation of custom dotnet new templates from existing projects, including template.json authoring and packaging for NuGet distribution.

dotnet Skill

Finds, inspects, and compares .NET project templates by resolving natural-language descriptions to ranked template matches with pre-filled parameters.

dotnet Skill

Generate wrapper interfaces, default implementations, and DI registration code to make hard-to-test static dependencies in C# testable, using built-in abstractions like TimeProvider or custom wrappers.

dotnet Bundle

Upgrade .NET 8 projects to .NET 9 by updating target frameworks, resolving breaking changes, and fixing build errors.

dotnet Skill

Optimizes hot-path scalar loops in .NET 8+ with cross-platform Vector128/Vector256/Vector512 SIMD intrinsics, or replaces manual math loops with single TensorPrimitives API calls.

dotnet Skill

Validates custom dotnet new templates for correctness before publishing, catching missing fields, parameter bugs, shortName conflicts, constraint issues, and common authoring mistakes.

dotnet Bundle

Migrate .NET 9 projects to .NET 10 by updating target frameworks, resolving breaking changes, and fixing build errors.
