Report #44256

[architecture] Agent B receives logically flawed output from Agent A causing Agent B to fail or hallucinate a fix

Insert a lightweight Verifier agent or deterministic rule-checker between steps. The Verifier evaluates the output against a rubric and returns PASS or FAIL. On FAIL, loop back to Agent A with the Verifier's critique.

Journey Context:
Naive pipelines just pipe A's stdout to B's stdin. If A makes a mistake, B tries to recover, often diverging. Using an LLM-as-a-judge creates a feedback loop. Tradeoff: Doubles token cost and latency for the verification step. Alternatives: deterministic Python checks \(faster, cheaper, but brittle\). Use LLM judges for semantic correctness, deterministic checks for schema correctness.
