Build augmented reality interfaces for display glasses using Jetpack Compose Glimmer, covering design principles, theming, input mapping, and projected activity setup.

Migrates an Android XML View to Jetpack Compose using a structured 10-step process, from candidate selection and analysis to theming, layout conversion, validation, and cleanup.

Scaffolds new agent skills conforming to the Agent Skills specification and dotnet/skills repository conventions, generating SKILL.md files with proper frontmatter and directory structures.

Scaffolds eval.yaml test files for agent skills in the dotnet/skills repository, including scenario writing, assertion definition, and rubric creation.

Scaffolds VS Code custom agent files (.agent.md) with YAML frontmatter, tool configuration, handoffs, and instructions for specialized AI personas.

Run, filter, or troubleshoot .NET tests with `dotnet test`, detecting the test platform (VSTest vs Microsoft.Testing.Platform) and framework to apply the correct command syntax.

Calculates CRAP (Change Risk Anti-Patterns) scores for .NET methods by combining cyclomatic complexity with code coverage data from Cobertura XML reports.

Install a .NET SDK into a project-local directory for safe preview testing, version pinning, or reproducible team setups without modifying the system-wide installation.

Grades individual test methods and produces a compact markdown table with a letter grade, score band, and one-line note for each test.

Configure and collect crash dumps for modern .NET applications (CoreCLR and NativeAOT) on Linux, macOS, and Windows, including containers.

Add light/dark mode, custom branded themes, and runtime theme switching to .NET MAUI apps using AppThemeBinding, ResourceDictionary swapping, and system theme detection APIs.

Analyzes test suites across multiple languages and tags each test with standardized traits (positive, negative, critical-path, etc.) for better test categorization and coverage visibility.

Test C# MCP servers at unit and integration levels using xUnit, Moq, and the MCP client SDK.

Reference for test filter syntax across VSTest and MTP platforms, covering MSTest, NUnit, xUnit v3, and TUnit frameworks with examples and translation guidance.

Author and review GitHub Actions workflow YAML to ensure syntactic and structural correctness, preventing failures from unquoted expressions and other YAML-vs-Actions traps.

Run, debug, and interactively test C# MCP servers locally with IDE configuration, MCP Inspector, and GitHub Copilot Agent Mode integration.

Provides guidance on using the new .NET 10 cross-platform safe area API for edge-to-edge layouts, keyboard avoidance, and migration from legacy iOS-only APIs.

Sets up Microsoft Testing Platform hot reload to iterate fixes on failing tests without rebuilding, covering package installation, environment configuration, and the iterative workflow.

Create MCP servers using the C# SDK and .NET project templates, covering scaffolding, tool/prompt/resource implementation, and transport configuration for stdio and HTTP.

Migrate .NET projects from per-project package versioning to NuGet Central Package Management (CPM) using Directory.Packages.props, with baseline build capture, version conflict resolution, and post-conversion validation.

Publish and deploy C# MCP servers to NuGet, Docker, Azure, and the MCP Registry.

Add authentication and authorization to a Blazor Web App, handling render modes, Identity pages, and auth state serialization.

Plan complex Blazor UI features by decomposing them into focused, composable components with clear data flow and implementation order.

Add, review, or fix JavaScript interop in Blazor components, including collocated modules, lifecycle timing, batching, typed wrappers, and disposal patterns.

Create, run, configure, and review BenchmarkDotNet microbenchmarks for .NET code, covering project setup, comparison strategies, and cost-aware execution.

Wire UI controls to ViewModel properties with compile-time safety, change notification, and minimal overhead using .NET MAUI data bindings.

Improve CLI build performance by enabling MSBuild Server for persistent caching of evaluation results across sequential builds.

Analyzes test suites to measure assertion diversity, detect shallow or trivial assertions, and identify tests that lack meaningful verification.

Analyzes .NET project code coverage and CRAP (Change Risk Anti-Patterns) scores to identify risk hotspots, methods blocking coverage gains, and prioritize where to add tests.

Analyzes production code to find gaps in existing tests by reasoning about hypothetical mutations and checking whether tests would catch them.

Run file-based C# apps with the .NET CLI for quick experiments, prototypes, and small utilities without creating a project.

Correctly call native C/C++ libraries from .NET using P/Invoke and LibraryImport, covering function signatures, string marshalling, memory lifetime, SafeHandle, and cross-platform patterns.

Guides technology selection and implementation of AI and ML features in .NET 8+ applications using ML.NET, Microsoft.Extensions.AI, Microsoft Agent Framework, GitHub Copilot SDK, ONNX Runtime, and OllamaSharp.
