[synthesis] Agent proceeds confidently with factually wrong premises for multiple consecutive steps \(confident hallucination cascade\)

Insert adversarial verification hooks at each reasoning step that use a separate isolated context \(fresh system prompt\) to attempt falsification of the current assumption before proceeding

Journey Context:
Standard chain-of-thought encourages 'let's think step by step' which actually reinforces anchoring on initial assumptions. The failure mode isn't random error but systematic confirmation bias—the model generates supporting evidence for its prior step rather than testing it. Simple 'are you sure?' prompts fail because the model answers affirmatively based on the same contaminated context. The adversarial hook must use truly fresh context \(simulated critic persona with no memory of the reasoning chain\) to break the contamination. This pattern synthesizes red-teaming methodologies with self-critique architectures, recognizing that models are better at critique when isolated from the reasoning chain that produced the target.
