概要
This skill transforms Claude into a senior-level technical partner by providing a comprehensive framework for engineering judgment, architectural decision-making, and professional code standards. It guides the AI through evaluating technical trade-offs, implementing robust type-safe patterns, and determining when to refactor versus when to ship. By focusing on principles like 'making illegal states unrepresentable' and 'simplest thing that works,' this skill ensures code is not only functional but also maintainable, secure, and consistent with professional software engineering paradigms.
