When should I use safeParse vs parse?

Use safeParse for all user-facing validation and external data sources to handle errors as data without throwing exceptions. Reserve parse for internal configurations where an invalid value represents a critical programming error.

Why use Zod instead of standard TypeScript interfaces?

TypeScript only provides compile-time checking for code you control. Zod provides runtime validation for data you don't control (like APIs or forms) and automatically generates types from schemas so your validation and types never drift apart.

How does this skill handle cross-field validation like password confirmation?

The skill provides patterns for using superRefine, which allows you to access the entire data object to compare fields and attach error messages to specific property paths.

Can Zod automatically convert data types?

Yes, this skill includes patterns for using z.coerce to turn string inputs into numbers or booleans, and .transform() to convert validated strings into complex objects like Date instances.

API 개발

Implements robust TypeScript runtime validation using Zod for API responses, form inputs, and system boundaries.

This skill provides specialized guidance for implementing professional Zod schema validation patterns in TypeScript projects. It ensures data integrity by enforcing strict validation at trust boundaries—such as API responses, form inputs, and configuration files—while automatically deriving TypeScript types from schemas to prevent definition drift. Built for Zod v4, it covers advanced patterns including discriminated unions, data transformations, and safe parsing to prevent unhandled exceptions, helping developers maintain clean, type-safe codebases that handle external data reliably.
