Report #68683

[architecture] Agent B receives garbage from Agent A and hallucinates a plausible continuation, masking the failure

Insert a lightweight Verifier agent \(or deterministic validator\) between steps. The Verifier checks the output against the step's goal before passing it on.

Journey Context:
In a chain, errors compound. If A fails silently, B tries to make sense of it. A separate, smaller model acting as a judge \(LLM-as-a-judge\) or a python script checking constraints can catch A's failure early. Tradeoff: adds latency and cost, but prevents cascading hallucinations.
