Does it support React Hook Form?

Absolutely. It provides specific implementation patterns for connecting Zod schemas to React Hook Form using the zodResolver library.

How does this skill help with Zod 3 to 4 migration?

The skill identifies deprecated Zod 3 patterns, such as z.string().email(), and replaces them with modern Zod 4 top-level validators like z.email() for cleaner code.

Can I use this for complex object validation?

Yes, it includes patterns for nested objects, arrays, records, discriminated unions, and sophisticated refinements using superRefine for multi-field validation.

How does Zod 4 handle error messages compared to earlier versions?

Zod 4 introduces a more streamlined error parameter in the schema definition (e.g., z.string({ error: 'msg' })) which this skill helps you implement correctly.

API開発

Streamlines the creation, migration, and implementation of Zod v4 schemas for robust TypeScript data validation.

概要

This skill equips Claude with the specific patterns and syntax required for Zod v4, ensuring type-safe data validation and parsing in modern TypeScript applications. It provides comprehensive guidance on migrating from Zod 3 to 4, implementing top-level validators, handling complex object schemas, and utilizing advanced features like discriminated unions and transformations. Whether you are building API request adapters, form validation logic with React Hook Form, or data coercion layers, this skill ensures your schemas are concise, performant, and follow the latest Zod best practices.
