Use when building .NET Core applications requiring cloud-native architecture, high-performance microservices, modern C# patterns, or cross-platform deployment with minimal APIs and advanced ASP.NET Core features.
This skill embodies the principles of "Clean Code" by Robert C. Martin (Uncle Bob). Use it to transform "code that works" into "code that is clean."
Provides guidance for generating comprehensive C# unit tests in .NET projects. Use when writing, scaffolding, or improving unit tests for C# code using MSTest, NUnit, or xUnit frameworks. Covers framework detection, test structure, edge-case analysis, mocking rules, and best practices. DO NOT use for integration tests, end-to-end tests, or non-.NET languages.

Use when writing new functions, adding features, fixing bugs, or refactoring by applying TDD principles - write failing tests before implementation code, make them pass, then refactor.
Use during implementation when designing modules, functions, and components requiring SOLID principles for maintainable, flexible architecture.
Use when modifying existing files, refactoring, improving code quality, or touching legacy code by applying the Boy Scout Rule to leave code better than you found it.
