[frontier] How to verify agent is still following core instructions mid-session before drift manifests

Implement identity checkpoints every N turns: include a verification prompt requiring the agent to explicitly state its core instructions before proceeding. Structure: 'Before continuing, confirm your operating constraints: \[list key constraints\]. Acknowledge and proceed.' Log whether the agent's acknowledgment matches the original instructions — mismatches are early drift signals that precede behavioral drift by 5-10 turns.

Journey Context:
Teams initially tried passive monitoring \(checking if outputs still match constraints\), but by the time drift is visible in outputs, it is already entrenched. The checkpoint pattern is active — it forces the agent to re-engage with its instructions before drift manifests in behavior. The acknowledgment step is not just verification, it is therapeutic: the act of stating the instructions re-weights them in the model's current attention window. This is similar to how repeating a mantra maintains focus under distraction. The logging aspect is crucial for production systems — it provides a drift early-warning signal before behavioral drift occurs, giving operators a 5-10 turn advance window to intervene.
