This skill provides Claude with expert-level guidance for functional programming in Haskell, focusing on robust domain modeling and compiler-enforced correctness. It enables the implementation of zero-overhead type safety using newtypes, validated data construction via smart constructors, and advanced effect management through the Three Layers Pattern. By leveraging idiomatic patterns like GADTs for state machines and property-based testing with Hedgehog, this skill helps developers build highly reliable software while avoiding common pitfalls like lazy evaluation space leaks and string-type inefficiencies.
