How does it handle dependency injection?

The skill provides patterns for defining services using Context.Tag and composing them into Layers, allowing for clean, testable, and modular codebases.

Why does the skill suggest cloning the Effect source code?

By indexing the core Effect source code locally, the skill can resolve complex type errors and implementation ambiguities that are not always clear from high-level documentation.

What is the primary benefit of using this Effect-TS skill?

It ensures that Claude follows idiomatic functional programming patterns, preventing common mistakes like using try-catch inside generators and ensuring strict type safety for errors.

Can it help me move away from throwing exceptions?

Absolutely. It focuses on converting traditional exceptions into typed errors using Effect's fail and catchTag mechanisms, making error states explicit in your types.

Does this skill help with Next.js development?

Yes, it includes specific guidance for Effect + Next.js integration, particularly focusing on the @prb/effect-next ecosystem for seamless framework support.

API開発

Guides the implementation of functional programming patterns using the Effect library for robust TypeScript applications.

概要

The Effect-TS Expert skill transforms Claude into a specialized consultant for functional programming in TypeScript. It provides idiomatic patterns for service composition, dependency injection via Layers, and comprehensive error management using Effect's typed error system. Whether you are refactoring imperative code, managing complex resource lifecycles with Scopes, or integrating with Next.js, this skill ensures your implementation follows canonical best practices. It proactively researches the Effect source code and your project's existing patterns to deliver type-safe, maintainable, and production-ready solutions.
