Validation

This skill covers creating and organizing Zod validation schemas that are shared between frontend forms and backend API routes. It includes standard validator creation, schema organization by feature, Drizzle-Zod integration for generating schemas from database tables, custom refinements for complex validation rules, and building shared reusable schema primitives.
