Report #50624

[frontier] Agent has drifted significantly from its original instructions but there's no mechanism to detect the drift until a constraint violation becomes visible to the user

Implement periodic 'identity verification' steps in your agent loop. Every N turns \(typically 10-15\), insert a hidden verification prompt: 'Before continuing, list the 3 most important constraints you are operating under.' Compare the output against the original constraint list to detect drift before it causes violations.

Journey Context:
Drift is invisible until it causes a problem. By the time you notice the agent has stopped following a constraint, it may have been drifting for 20\+ turns, potentially causing silent errors. The solution is proactive verification: forcing the agent to articulate its constraints at regular intervals. This works because the act of stating constraints re-activates them in the model's attention—a form of self-priming that partially resets drift. What people get wrong: relying on human monitoring to catch drift, which doesn't scale. The tradeoff is that verification steps consume tokens and add latency. Production teams in 2025 solve this by running verification as a parallel process \(a lightweight 'supervisor' agent\) rather than interrupting the main conversation flow, or by embedding verification in chain-of-thought reasoning that doesn't produce visible output.
