Explicit is better than implicit - Make validation rules clear and explicit using Zod schemas. Every validation rule should be visible in the schema, not hidden in business logic. Error messages should be specific and helpful, telling users exactly what went wrong and how to fix it.

Design to fail fast and early - Validate input as early as possible, ideally on the client side before submission, and always on the server side. Return clear, specific error messages immediately so users can fix issues without frustration.

Epic Stack uses Conform to handle forms with progressive enhancement.
