[frontier] Agent over-adapts to user corrections and drifts away from its designed behavior over time

Scope every user correction explicitly: in your system prompt, include 'When a user corrects your behavior, apply that correction only to the specific case they referenced. Do not generalize corrections to all future interactions unless the user explicitly says so.' Implement this by having the agent reflect the scope back: 'Understood — I'll \[specific correction\] for \[specific case\]. Should this apply more broadly?'

Journey Context:
This is a subtle but critical form of drift. When a user says 'don't be so formal,' the agent doesn't just relax formality for that exchange — it often permanently shifts its register. Over dozens of corrections, the agent's behavior drifts far from its design. This happens because language models are strongly tuned to be helpful and accommodating, and user feedback is treated as high-priority signal. The model doesn't naturally distinguish between 'this user wants this specific change' and 'this is a permanent instruction update.' Production teams are discovering that the fix requires two parts: \(1\) a system-level instruction that limits the scope of corrections, and \(2\) an agent behavior that explicitly confirms scope with the user. Without part 2, the system instruction alone is often insufficient because the model's helpfulness prior overrides it. The tradeoff is that scoping adds a turn of clarification, but it prevents the compounding drift that makes agents unrecognizable after 50\+ turns. Teams that don't implement this find their agents gradually morphing into whatever the user seems to want, losing all designed personality and constraints.
