Report #99933

[architecture] A sub-agent's output is accepted without an independent verification step, letting subtle errors cascade

Insert a dedicated critic/verifier agent that receives the original prompt, the producer's output, and a rubric, and returns a structured pass/fail \+ annotated critique. On failure, route back to the producer with the critique, up to a max retry count, then escalate. Use CriticGPT-style critique models for code; use deterministic validators where possible.

Journey Context:
As models improve, their mistakes become subtler and harder for downstream agents to catch. A separate critic breaks the echo chamber: it is instructed to find flaws against explicit criteria rather than continue the task. It can be an LLM or a deterministic checker. Tradeoffs: latency, cost, and the critic's own hallucinations. Mitigate by requiring the critic to quote exact spans and by falling back to human review on disagreement or high-stakes outputs.
