How does Zod 4 differ from Zod 3 in this skill?

This skill prioritizes Zod 4's new top-level validators like z.email() and z.uuid() over the older chainable string methods, and utilizes the updated error object syntax.

Can I use this skill for frontend form validation?

Yes, it includes specific implementation patterns for React Hook Form using the zod-resolver to handle complex UI validation states.

How does it handle complex conditional validation?

The skill includes patterns for discriminated unions and superRefine, which are essential for validating objects where the schema depends on the value of a specific key.

Does this skill support data type conversion?

Absolutely. It provides patterns for coercion, allowing you to automatically convert strings to numbers, booleans, or Date objects during the validation process.

API Development

Implements robust TypeScript-first schema validation and parsing using optimized Zod v4 patterns.

About

The Zod 4 skill equips Claude with specialized knowledge for defining, parsing, and validating data structures using the latest Zod version 4 syntax. It streamlines the creation of type-safe schemas for APIs, forms, and configuration files while providing clear patterns for migrating legacy Zod 3 codebases. By focusing on advanced features like discriminated unions, data coercion, and custom refinements, this skill ensures that your application's data integrity is maintained with minimal boilerplate and maximum performance.
