A developer built a planning agent called PlannerCritic, designed to avoid dangerous outputs by refusing tasks it cannot confidently complete. During testing, the agent escalated 96 out of 97 strict goals, a metric that initially appeared as failure. However, the developer argues this high refusal rate was a sign of the agent's strength, preventing potentially catastrophic outcomes from plausible but flawed plans. The key product lesson learned is that for high-stakes systems, a confident refusal with a precise explanation of the blocker is more valuable than a seemingly successful plan with hidden risks. AI
