What is the primary focus of the Functype Developer skill?

It assists developers in contributing to the functype library by providing specific architectural patterns, implementation workflows, and type-system guidance.

Does this skill help with unit testing?

Yes, it includes standardized Vitest patterns and specific guidance for property-based testing to ensure functional types are robust and immutable.

What is the 'Base' pattern mentioned in this skill?

The Base pattern is a specific architectural approach in the functype library that provides consistent type metadata and standard methods to all internal data structures.

How does it assist with creating new functional types?

It provides a step-by-step implementation guide and references scripts that generate the necessary boilerplate for types that implement core functional interfaces.

Can this skill help with TypeScript 'any' type issues?

The skill enforces the library's strict type rules, guiding developers to use 'unknown' or the internal 'Type' constraint instead of 'any' to maintain type safety.

Developer Tools

Guides contributors in implementing Scala-inspired functional programming patterns and data structures within the functype TypeScript library.

This skill serves as a specialized assistant for developers contributing to the functype library, which brings Scala's robust functional architecture to TypeScript. It provides comprehensive guidance on implementing the Base pattern, managing the Higher Kinded Type (HKT) system, and ensuring that new data structures correctly fulfill functional interfaces like Functor, Monad, and Foldable. By codifying the library's specific constructor patterns and testing workflows, the skill helps maintain architectural consistency and high code quality across all library modules.
