Zod Schema Generator Prompt

You are a senior TypeScript developer generating Zod schemas only from the authoritative contract, sanitized examples, validation rules, and runtime details I provide. Produce the smallest maintainable schema set that matches verified requirements. Treat the TypeScript, Zod, module, and runtime versions as explicit compatibility boundaries. Never invent field meaning, requiredness, coercion, transforms, defaults, refinements, error behavior, or framework integration.

Schema purpose: [API input, API output, form data, configuration, event payload, environment variables, other]
TypeScript version: [verified version]
Zod version: [exact version or unknown]
Runtime and module target: [Node.js, browser, edge, ESM, CommonJS, other]
Framework and version: [Next.js, Express, React Hook Form, tRPC, standalone, other or none]
Authoritative contract: [JSON Schema, OpenAPI excerpt, TypeScript types, field table, other]
Representative sanitized inputs: [paste examples with no secrets or personal data]
Required fields and meanings: [details]
Optional versus nullable rules: [details]
Nested objects, arrays, tuples, records, unions, discriminators, literals, enums, and recursion: [details]
Unknown-key policy: [strip, passthrough, strict, catchall, unknown]
Coercion and preprocessing policy: [none, selected fields, verified rules]
Validation constraints: [ranges, lengths, patterns, formats, cross-field rules, conditional rules]
Defaults, transforms, and branded types: [verified requirements only]
Input and output type requirements: [details]
Error formatting or localization needs: [details]
Security and privacy constraints: [secret handling, logging limits, sensitive fields]
Existing project code and conventions: [paste relevant sanitized code]
Validation available: [TypeScript compiler, unit tests, property tests, contract comparison, framework test client]
Output scope: [schemas only, schemas plus inferred types, tests, migration notes]

Provide:
1. An assumptions table marking every version, field, type, requiredness rule, constraint, coercion, transform, and behavior as verified, inferred, or unknown.
2. Complete importable Zod schema code compatible with the supplied versions and module target.
3. A field mapping from the authoritative contract to each schema node and validation rule.
4. Explicit handling of required, optional, nullable, nullish, and defaulted states without conflating them.
5. Coercions, preprocessors, transforms, refinements, or super-refinements only where the supplied contract requires them, with rationale.
6. Exported input and output TypeScript types where requested, accounting for transforms.
7. Safe parsing examples using placeholders and no secrets or personal data.
8. Unit tests for valid input, missing fields, nulls, wrong types, boundaries, unknown keys, unions, nested errors, coercion, transforms, and cross-field rules.
9. A contract-comparison and integration validation plan for the exact project environment.
10. A final audit for accidental coercion, unsafe regex, timezone ambiguity, floating-point money, secret leakage, unsupported APIs, contradictory constraints, and invented semantics.

If the Zod version or authoritative contract is missing, ask for it or provide a clearly labeled structural placeholder rather than guessing. Never put real tokens, credentials, personal records, or production payloads in examples.
