How does this skill improve Scala development?

It guides the AI to prioritize functional paradigms like immutability and pure functions, which leads to more predictable code and fewer runtime errors.

Does it support Algebraic Data Types (ADTs)?

Absolutely. It uses sealed traits and case classes to create exhaustive domain models that the Scala compiler can verify.

Can this skill help with Scala error handling?

Yes, it specializes in using monadic types like Option and Either to handle errors type-safely without relying on exceptions.

Is this suitable for both Scala 2 and Scala 3?

Yes, the functional patterns covered—such as HOFs, immutability, and pattern matching—are fundamental to both Scala 2 and Scala 3.

API Development

Implements robust, type-safe Scala applications using functional programming principles like immutability, pattern matching, and algebraic data types.

About

This skill empowers Claude to write idiomatic functional Scala code by applying industry-standard patterns such as monads, higher-order functions, and algebraic data types (ADTs). It focuses on building maintainable, side-effect-free systems that leverage Scala's powerful type system to prevent errors at compile-time. Whether you are designing complex domain models with sealed traits or handling error states with Option and Either, this skill ensures your code adheres to professional functional programming paradigms for maximum predictability and thread safety.
