Report #85612

[synthesis] Agent declares a task complete and stops looping, even though the objective is only partially met, because the self-evaluation prompt is biased towards confirmation

Frame the task completion check as an adversarial review. Instead of 'Is the task done?', ask 'What evidence proves the task is NOT done?' and require the agent to execute a verification step.

Journey Context:
RLHF-tuned models are heavily biased towards being helpful and agreeing with the user. When an agent asks itself 'Have I achieved the goal?', this sycophancy bias translates into a premature 'Yes'. The agent finds a local optimum that looks like success \(e.g., the file exists\) but fails the global objective \(e.g., the file has the correct content\). By flipping the prompt to an adversarial frame, you counteract the sycophancy bias. The tradeoff is that an adversarial frame might cause the agent to loop unnecessarily on perfect output, but this is far safer than premature termination.
