Zod
> TypeScript-first schema validation with static type inference.
Best use case
Zod is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
> TypeScript-first schema validation with static type inference.
Teams using Zod should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# Zod
> TypeScript-first schema validation with static type inference.
## When to Use
- Validating API request/response bodies
- Form validation with react-hook-form
- Environment variable validation
- Runtime type checking at system boundaries
## Core Patterns
### Schema Definition
```typescript
import { z } from "zod";
const UserSchema = z.object({
name: z.string().min(1).max(100),
email: z.string().email(),
age: z.number().int().positive().optional(),
role: z.enum(["admin", "user", "moderator"]),
tags: z.array(z.string()).default([]),
});
type User = z.infer<typeof UserSchema>;
```
### Validation
```typescript
// parse() throws on failure, safeParse() returns result object
const result = UserSchema.safeParse(data);
if (!result.success) {
console.log(result.error.flatten()); // { fieldErrors: { email: ["Invalid email"] } }
}
```
### Common Combinators
- `.transform()` — transform after validation
- `.refine()` — custom validation logic
- `.superRefine()` — multi-field validation with path
- `z.discriminatedUnion()` — tagged unions
- `z.intersection()` — combine schemas
- `.passthrough()` / `.strict()` — unknown key handling
### Integration
- **react-hook-form**: `zodResolver(schema)` in useForm
- **tRPC**: schemas as input/output validators
- **Next.js**: server action validation
- **Env vars**: `z.object({...}).parse(process.env)` at startupRelated Skills
