[synthesis] Agent confidently repeats wrong approach for multiple consecutive steps

Inject a step evaluator that independently checks if the cumulative state is closer to the goal, and if 2 consecutive steps fail to change the evaluation score, force a strategic pivot prompt that clears the recent scratchpad and forces a new plan.

Journey Context:
Agents often get stuck in sunk-cost loops. If an agent makes a wrong assumption, it tries to fix the symptoms of that assumption rather than questioning the assumption itself. The LLM sees its own previous reasoning in the context and feels compelled to continue the narrative. Simple retry limits don't work because the agent thinks it's making progress. A meta-evaluator that scores the distance to goal rather than the consistency of the plan is required to break the narrative consistency bias, combining insights on generative agent looping with reward-hacking mitigation.
