Designing Zod schemas for Mastra agent outputs involves applying constraint patterns and self-documenting principles to ensure data integrity. You define structured types for summaries, findings, and scores to improve LLM reliability.

Validating inter-field dependencies in a Zod schema is achieved using refinements. Refinements allow you to apply custom validation logic across multiple fields, ensuring complex data relationships are correctly checked before processing.

Defining Zod schemas for Mastra workflow suspend and resume states requires modeling the exact data structure needed to pause execution. You apply schema composition to maintain data integrity and ensure reliable state transitions across steps.

Using discriminated unions and recursive schemas in Zod allows for complex data modeling of nested or variant structures. These advanced techniques enable flexible, type-safe parsing of hierarchical data formats within TypeScript applications.

Use Zod transforms when you need to modify or convert input data into a different output type, whereas refinements are for validating existing data without changing its shape. Both ensure data conforms to required formats and constraints.
