Code Quality Principles

This is an always-on skill that enforces KISS, YAGNI, and SOLID principles during code reviews and refactoring. It gives you language-specific examples in Python, Rust, and TypeScript showing simple vs over-engineered approaches, and includes a quick reference table with red flags for each principle. The real value is in the "When Principles Conflict" section, which acknowledges that KISS sometimes beats SOLID on small projects and that YAGNI means you shouldn't add abstractions until you have multiple implementations. It's set to low complexity with a fast model hint, so it won't slow you down, and it integrates with the broader quality gates system if you're using that workflow.
