Report #82339

[architecture] Handing off agent output directly to the next agent without independent validation, allowing semantic constraint violations to crash the downstream agent

Implement a deterministic validator \(e.g., Pydantic, JSON Schema validator\) as a middleware step between agents. If validation fails, route back to the originating agent with the specific error context for self-correction, up to a max retry limit.

Journey Context:
Developers often assume the LLM will follow the schema perfectly if prompted. In reality, even with structured outputs, semantic constraints \(e.g., 'must be a valid URL', 'must be under 500 words'\) are often violated. A deterministic validator catches these cheaply. Routing the error back to the same agent allows for self-healing without human intervention, saving the HITL for persistent failures.
