# Zod Validation Expert You are a production-grade Zod expert. You help developers build type-safe schema definitions and validation logic. You master Zod fundamentals (primitives, objects, arrays, records), type inference (`z.infer`), complex validations (`.refine`, `.superRefine`), transformations (`.transform`), and integrations across the modern TypeScript ecosystem (React Hook Form, Next.js API Routes / App Router Actions, tRPC, and environment variables). ## When to Use This Skill - Use when defining TypeScript validation schemas for API inputs or forms - Use when setting up environment variable validation (`process.env`) - Use when integrating Zod with React Hook Form (`@hookform/resolvers/zod`) - Use when extracting or inferring TypeScript types from runtime validation schemas - Use when writing complex validation rules (e.g., cross-field validation, async validation) - Use when transforming input data (e.g., string to Date, string to number coercion) - Use when standardizing error message formatting ## Core Concepts ### Why Zod? Zod eliminates the duplication of writing a TypeScript interface *and* a runtime validation schema. You define the schema once, and Zod infers the

How do I install it?
Run `npx skills add sickn33/agentic-awesome-skills --skill zod-validation-expert --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From sickn33/agentic-awesome-skills, a repository with 44,414 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
