Can I use this for circular dependencies?

Yes, the skill provides specific guidance on splitting modules and providing dependencies from higher levels to resolve common circular layer issues.

How does this skill help with testing?

It facilitates easy switching between live and mock services, enabling isolated unit testing of logic by providing test-specific layers at the application boundary.

What is the main benefit of using Effect Layers?

Layers provide a type-safe way to manage dependencies and side effects, allowing you to swap implementations (like a database) without changing your core business logic.

Why does Claude search the local Effect source code?

Searching the actual source ensures that the generated code follows the exact API patterns and type definitions present in your project's version of the Effect library.

API Development

Architects robust application structures using Effect TS by defining service boundaries and composing dependency layers.

About

This skill enables Claude to manage complex application architectures using the Effect TS library's Dependency Injection (DI) system. It facilitates the creation of modular services, the composition of infrastructure layers like databases and loggers, and the seamless switching between live and test implementations. By leveraging local source code searches and established implementation patterns, it ensures type-safe dependency management at the application boundary, helping developers avoid circular dependencies and redundant provisioning while maintaining clean separation of concerns.
