Haskell Functional Software Crafter
Implements high-assurance Haskell software using advanced type systems, pure functional patterns, and robust effect management.
The nw-fp-haskell skill provides specialized guidance for architecting and developing mission-critical applications in Haskell. It focuses on leveraging Haskell's unique strengths, such as GADTs for type-safe state machines, smart constructors for domain validation, and the Three Layers pattern for clean effect management. This skill helps developers move from basic functional concepts to production-grade software craftsmanship, ensuring codebases remain maintainable, testable, and correct-by-construction through rigorous type-level programming and property-based testing patterns.
