Report #51972

[architecture] Relying on a single agent to both generate and verify its own output leads to blind spots and sycophancy

Implement a separate, independent Verifier agent with a distinct system prompt and stricter evaluation criteria to judge the Worker agent's output before passing it to the next stage.

Journey Context:
Self-correction works for formatting but fails for logical hallucinations because the LLM is biased toward its own generation. A separate verifier \(Generator-Verifier architecture\) breaks this bias. The tradeoff is doubling token cost and latency. However, for high-stakes pipelines, this separation of concerns is the only reliable way to catch subtle logic errors that a self-reviewing agent will gloss over.
