This skill transforms the agent into an expert in Zod v4, focusing on runtime type validation and parsing of untrusted data at system boundaries. It provides a rigorous set of rules to ensure type safety, prevent common pitfalls, and optimize schema performance in TypeScript applications.
Use this skill when working with Zod for API input/output validation, form validation, environment variable parsing, or when migrating from Zod v3 to v4. It is particularly useful for complex schema design involving discriminated unions, recursive types, and custom refinements.
