Report #38355

[architecture] Downstream agents blindly trust the output of upstream agents, allowing subtle logic errors to cascade

Insert an independent Verifier agent at the boundary before passing artifacts to the next agent, explicitly checking the output against the original task requirements without access to the generating agent's context.

Journey Context:
A common anti-pattern is the happy path pipeline where Agent A writes code, and Agent B deploys it. If Agent A writes subtly flawed code, Agent B will deploy broken software. By inserting a Verifier agent whose only system prompt is to find flaws in the output against the spec, you create separation of concerns. The tradeoff is increased latency and token cost \(running an extra LLM call per step\), but it dramatically reduces cascading logic failures. For code, deterministic execution \(unit tests\) is even better than an LLM verifier.
