Can I use this skill to generate JSON Schemas?

Yes, Effect Schema has built-in interoperability for generating JSON Schemas from your TypeScript definitions, ensuring your API documentation stays in sync with your code.

Why does this skill prefer Tagged Unions over optional properties?

Tagged unions make application states explicit and enable exhaustive pattern matching, which prevents 'impossible states' and makes your code much more predictable compared to using multiple optional fields.

How does Schema.Class differ from Schema.Struct?

Schema.Class provides better ergonomics by allowing you to define methods directly on the schema and provides built-in support for Schema.is() type guards, which is more powerful than plain objects.

Does this skill help with parsing raw JSON?

Absolutely. It promotes using Schema.parseJson, which combines JSON parsing and schema validation into a single type-safe step, preventing common runtime errors associated with JSON.parse().

API 开发

Enables type-safe data validation and bidirectional transformations using industry-standard Effect Schema patterns.

This skill provides Claude with specialized knowledge of the Effect Schema library to build robust, type-safe data layers. It emphasizes production-grade patterns such as using tagged unions to eliminate impossible states and leveraging class-based schemas for better ergonomics and domain logic. Whether you are defining API contracts, parsing complex JSON, or implementing custom transformations, this skill ensures your implementation follows the latest Effect ecosystem best practices for maximum reliability and type inference.
