How would you answer an interview scenario involving Structured outputs and tool calling?

For an interview scenario involving Structured outputs and tool calling, I would first clarify the business goal, scale, constraints, and the failure or quality attribute the interviewer wants to explore. Structured outputs constrain model responses to machine-readable schemas, while tool calling lets a model request approved external actions or data. In this scenario, for an assistant that can create support tickets, explain schema validation, authorization, retries, and how you would prevent unintended actions. I would then explain the main alternatives and tradeoffs, identify likely failure modes, and describe how I would validate the solution through testing, observability, security controls, and recovery or rollback planning.
