Effect-TS is a powerful TypeScript library for building robust, type-safe applications using a functional effect system that manages errors, dependencies, and resources.

Can I use this for data validation?

Absolutely. It includes comprehensive patterns for Effect Schema, allowing for type-safe decoding and encoding of external data with detailed error reporting.

How does it handle dependency injection?

The skill implements the Service and Layer patterns, allowing Claude to define explicit requirements for functions and provide implementations at the application's edge.

How does this skill improve error handling?

It enables Claude to utilize Effect's type-safe error channel, ensuring that all possible failure paths are tracked in the type system rather than being lost in generic Promises.

Does this skill support Effect.gen syntax?

Yes, the skill provides the patterns necessary for Claude to write clean, imperative-looking asynchronous code using generators while maintaining full functional purity.

API開発

Implements robust, type-safe functional systems using Effect-TS for advanced error handling, dependency injection, and resource management.

This skill empowers Claude to architect and build high-performance TypeScript applications using the Effect ecosystem. It provides expert guidance on using Effect.gen for readable async code, managing service dependencies with Context.Tag and Layer, and ensuring type-safe data validation via Effect Schema. It is particularly useful for developers building resilient systems that require explicit error tracking, deterministic resource cleanup, and highly composable functional patterns that go beyond standard Promises.
