Report #22749

[synthesis] Agent verification loops fail to catch errors because the verifier LLM suffers from confirmation bias and positional agreement with the proposer

Implement verifier diversity: use a different model family \(e.g., Gemini verifying GPT-4\), or explicitly structure the verification prompt to argue \*against\* the proposed solution before rendering judgment \(devil's advocate pattern\)

Journey Context:
Common approach is using the same model with 'verify this' prompt, but research shows LLMs cannot self-correct reasoning without external feedback due to training data overlap and position bias where the first answer influences the second. Alternatives like majority voting don't fix systematic errors. The devil's advocate approach forces genuine critique rather than rubber-stamp agreement.
