Report #78762

[architecture] Hallucinations or errors from an early agent compound uncontrollably through subsequent agents

Implement a 'Verifier' agent or deterministic validation step at the boundary between agents to check the output against the original goal and constraints before passing it down the chain.

Journey Context:
In a linear agent chain, if Agent 1 makes a subtle reasoning error, Agent 2 assumes it as ground truth and builds on it, leading to cascading failures. People try to fix this by making the prompt of Agent 1 better, but this doesn't eliminate errors. The architectural fix is the Generator-Verifier pattern. A separate, cheaper/faster agent or a deterministic script evaluates the output against a rubric. Tradeoff: adds latency and token cost, but catches compounding errors early.
