Why does it need the Effect source code cloned locally?

It uses the local source code as a primary research reference to provide the most accurate implementation details for complex types and internal library behaviors.

Does this skill support Next.js?

Yes, it specifically covers Effect + Next.js integration patterns, including the use of @prb/effect-next for seamless full-stack functional development.

How does it handle dependency injection?

The skill uses idiomatic Effect patterns like Context.Tag and Layers to create modular, testable, and decoupled service architectures.

What is the Effect-TS Claude Code Skill?

It is a specialized plugin that enhances Claude's ability to write, refactor, and architect TypeScript code using the Effect library, focusing on functional programming best practices.

Can it help with debugging complex type errors?

Absolutely. It is designed to navigate Effect's sophisticated type system and provides research-backed solutions for complex error hierarchies and stream operations.
