Does this skill support migration from Zod v3?

Yes, it includes specific guidance on v4 changes, such as using .extend() instead of the deprecated .merge() and using top-level validation methods.

Why is method chain order important in Zod v4?

In Zod, methods like .optional() or .min() create new instances. This skill ensures you call metadata methods last so that annotations are attached to the final object.

Can this help with JSON schema conversion?

Yes, it provides patterns and references for converting Zod schemas to JSON schema formats for interoperability with other tools.

How does this skill handle Zod v4 metadata?

It enforces the use of .meta() and .describe() at the end of method chains to prevent metadata loss, as Zod methods often return new schema instances.

Implements TypeScript-first schema validation using Zod v4 best practices and advanced metadata patterns.

This skill provides specialized guidance for working with Zod v4, focusing on building robust TypeScript schemas with static type inference. It specifically addresses the nuanced metadata registry system in v4, ensuring that annotations like descriptions and labels are correctly preserved through method chains. Whether you are migrating from v3, defining strict objects, or creating complex validation logic, this skill helps developers avoid common pitfalls such as lost metadata or deprecated method usage to ensure data integrity across the stack.
