Description

Hi

I am a bit new to laravel/ai but I have a question regarding agents that implements HasStructuredOutput

If the structured format of the StructuredAgentResponse doesn't follow the format defined in the schema - shouldn't an exception be thrown? Should this happen on the Prism level, the Laravel/Ai level - or am I supposed to do this myself?

I don't really see any point in structured output if I have no guarantee that the result will conform to my schema.

Contributor guide

Research direction
Implement validation of structured output against the schema and throw an exception when it doesn't conform. Consider where to place this validation (e.g., in the Prism level or Laravel/Ai level). Also consider providing clear error messages.
