What zod-validation-expert does

This skill configures the coding agent to build schema definitions for application inputs. It emphasizes parsing over simple validation, prompting the model to use type coercion on query strings or form payloads.

The instructions cover deriving static definitions via z.infer, processing responses with safeParse, and configuring transformations. It also supplies patterns for binding schemas to React Hook Form adapters and Next.js server actions.

Your project requires TypeScript and the zod package in node_modules. Without them, the generated schemas will fail compilation.

What it helps with

  • generate TypeScript types directly from runtime schemas
  • coerce and validate incoming form data in Next.js actions
  • wire Zod resolvers into React Hook Form components
  • implement cross-field validation rules using refine

Example prompts for the agent

  • Write a Zod schema for a user profile form with custom password matching logic.
  • Generate a typed validation schema for Next.js Server Actions handling FormData with boolean flags.
  • Create a discriminated union schema in Zod and extract the resulting TypeScript type.
