Can I use this skill for frontend form validation?

Absolutely. It provides patterns for attaching UI-specific metadata (labels, placeholders, descriptions) to schemas, which can be used to drive dynamic frontend forms.

Why does the order of .meta() matter in Zod v4?

In Zod v4, methods like .optional() or .min() return new schema instances. Calling .meta() at the end of the chain ensures the metadata is attached to the final version of the schema.

What is the primary benefit of the Zod v4 skill for Claude?

The skill ensures that Claude applies specific Zod v4 patterns, particularly the metadata registry system, which prevents common errors like losing metadata during schema instance creation.

Does this skill help with Zod v3 to v4 migration?

Yes, it identifies deprecated patterns like .merge() and suggests modern equivalents like .extend() and top-level type functions like z.email().

API 开发

Implements Zod v4 patterns and best practices for robust TypeScript schema validation and metadata management.

关于

This skill empowers developers to build more maintainable and type-safe TypeScript applications by providing expert guidance on Zod v4 implementations. It focuses on the modern metadata registry system, ensuring that developers use .meta() and .describe() correctly within method chains to prevent metadata loss. By highlighting common pitfalls—such as the deprecation of .merge() in favor of .extend() and the nuances of schema instance creation—this skill helps maintain clean, introspectable data models suitable for API validation, form generation, and automated documentation.
