When should I use Effect.gen?

Effect.gen should be used whenever you need to perform sequential operations or handle complex logic where the pipe syntax might become difficult to read.

Why does this skill discourage using if/else and loops?

Effect-TS emphasizes functional purity. By using Match and Array modules instead of imperative constructs, you achieve better type safety, exhaustiveness checking, and more composable code.

How does this skill handle domain errors?

It promotes the use of Schema.TaggedError, which allows errors to be treated as first-class citizens that are fully trackable by the TypeScript compiler.

What are the benefits of Schema-first modeling?

Defining data with Effect Schema provides a single source of truth for your types, runtime validation, and automated tools like encoders/decoders, reducing boilerplate and bugs.

Is this skill compatible with existing TypeScript projects?

Yes, it is designed to help you incrementally adopt Effect-TS patterns or maintain high standards in projects already using the Effect ecosystem.

API 개발

Enforces functional programming patterns and idiomatic Effect-TS conventions for robust, type-safe TypeScript development.

This skill acts as a specialized architect for the Effect-TS ecosystem, ensuring that Claude adheres to strict functional programming principles. It mandates the elimination of imperative constructs like loops and if/else statements in favor of Effect's powerful Match, Schema, and collection modules. By prioritizing schema-first data modeling and generator syntax, it helps developers build highly composable, maintainable, and predictable backend services that leverage the full power of the Effect ecosystem.
