Why does this skill recommend safeParse over parse?

safeParse returns a result object containing either the data or error issues without throwing exceptions. This allows for explicit error handling and prevents application crashes when processing invalid user input.

Does this skill support the latest version of Zod?

Yes, it includes specific guidance for Zod v4, covering performance improvements, top-level APIs like z.email(), and migration paths from v3 method chaining.

How do I prevent type duplication with this skill?

The skill enforces the use of z.infer to automatically derive TypeScript types from your Zod definitions, ensuring your validation logic and type system never drift apart.

What is the benefit of using discriminated unions in schemas?

Discriminated unions provide much clearer error messages and allow TypeScript to efficiently narrow types within conditional logic or switch statements based on a shared tag field.

Desarrollo de API

Implements robust TypeScript runtime validation using Zod schemas for API responses, web forms, and system configurations.

This skill provides a standardized framework for implementing Zod-based runtime validation at critical trust boundaries like API entry points and user forms. It enforces best practices such as deriving TypeScript types directly from schemas with z.infer, utilizing safeParse to prevent unhandled exceptions, and using named constants for validation limits. By providing patterns for discriminated unions, complex refinements, and data transformation, this skill ensures that your application remains type-safe and resilient against untrusted external data while minimizing code duplication.
