Report #59329

[architecture] Downstream agent attempts to fix or hallucinate around malformed output from an upstream agent

Implement a stateless 'Verifier' agent or deterministic validation step between agents. If validation fails, route back to the generator agent with the specific validation error, rather than passing garbage forward.

Journey Context:
LLMs are eager to please; if fed bad JSON or incomplete data, they will often try to infer the missing pieces rather than throwing an error. This leads to unpredictable, hard-to-debug states downstream. The tradeoff is that adding a verifier adds latency and token cost. However, it is far cheaper than letting an error cascade through 5 agents, requiring a complete restart. The verifier should be a separate, focused prompt \(or deterministic code\) that outputs a strict PASS/FAIL and rationale.
