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.
