Jev’s best use case for agent harnesses isn’t model routing or tool checks. It’s drift detection. It’s like telling someone they’re getting off topic without telling them how to fix it. Works for people. Will work for agents. Jev is fast and cheap enough to run continuously. Score every step for drift, then steer the agent back on course. No extra work for the prompt author.
