Effect Ts

Summary

Teaches Claude how to work with Effect-TS, the typed functional programming library that brings structured concurrency, dependency injection, and error channels to TypeScript. Covers the full stack: Schema validation, Layer composition, fiber-based concurrency primitives, Stream processing, and the Effect.gen generator syntax that makes it all readable. The paradigm guide is the smart part here,it explicitly tackles the mental model shift from Promises and includes refactoring recipes and anti-patterns. Most useful when you're either migrating a codebase to Effect or building services that need typed errors and testable dependencies. Not for React's useEffect or Redux side effects, despite the name collision.
