API Development

Implements type-safe data validation, parsing, and transformations using @effect/schema for robust TypeScript applications.

This skill provides specialized guidance for working with @effect/schema, the premier data modeling and validation library for the Effect ecosystem. It enables Claude to define complex schema structures, perform runtime data validation, and execute seamless transformations between internal and external data formats. Whether building API boundaries, processing form data, or managing internal state, this skill ensures strict type safety and predictable data handling across the entire application lifecycle, leveraging the power of functional programming in TypeScript.
