Implements robust TypeScript schema validation and parsing patterns using the latest Zod 4 features and syntax.
This skill provides comprehensive guidance for implementing type-safe data validation using Zod 4, focusing on modern patterns and migrations from version 3. It assists developers in creating schemas for primitives, complex objects, and discriminated unions while leveraging Zod 4's top-level validators such as z.email() and z.uuid(). Whether you are building API request validators, form schemas for React Hook Form, or data transformation pipelines, this skill ensures your validation logic is concise, efficient, and fully type-safe by adhering to the latest best practices.
