[synthesis] Agent becomes confidently wrong for multiple consecutive steps due to cascading confirmation bias

Introduce adversarial step-verification. Before executing a tool call based on a previous assumption, run a secondary, isolated LLM call with the prompt: 'Given the original goal, does the current step logically follow from the evidence, or is it rationalizing a prior assumption?'

Journey Context:
In multi-step ReAct loops, if an agent makes a minor incorrect assumption in step 1, it often forms a query in step 2 that is subtly biased to confirm step 1. The broad results from step 2 are then cherry-picked to reinforce the flawed premise. By step 3, the agent is entirely confident in a fabricated reality. Standard self-reflection \(asking the same model 'are you sure?'\) often amplifies the bias. The synthesis here is combining LLM sycophancy research with agent loop dynamics: you cannot break a confirmation loop with the same context that created it.
