You have to treat AI agents like employees who need regular performance reviews. Just as you wouldn’t let a human employee run a department for 3 years without checking if they’ve developed bad habits, you cannot deploy an AI agent, walk away, and assume it will function exactly the same way 90 days later. You must continuously monitor, audit, and prune its memory to keep it aligned with its original purpose.

Give an agent memory and it improves for a few weeks, then slowly forgets what it was for.
