This skill provides specialized guidance for C# developers to apply fundamental software engineering principles within the .NET ecosystem. It helps Claude identify and refactor common code smells such as magic numbers, over-engineered abstractions, and redundant validation logic. By enforcing DRY (Don't Repeat Yourself), KISS (Keep It Simple, Stupid), and YAGNI (You Aren't Gonna Need It), this skill assists in writing code that is not only functional but also highly maintainable, readable, and optimized for long-term project health.
