[frontier] Agent gradually absorbs user framing and assumptions, drifting from its assigned persona over long sessions

Implement identity ritual: at key decision boundaries, have the agent briefly restate its role and top constraints before generating its response. This can be enforced via a lightweight pre-processing step or a 'think before you act' instruction in the system prompt.

Journey Context:
Over long sessions, agents unconsciously align with the user's mental model, especially when the user is frustrated, insistent, or subtly reframing the task. This 'persona absorption' is subtle and cumulative—the agent at turn 50 may be unrecognizable from the agent at turn 1, not because it forgot its instructions but because it gradually reinterpreted them through the lens of user expectations. The identity ritual creates circuit breakers: before any significant decision, the agent re-anchors by restating its identity and constraints. The key is making the ritual brief and structured \(2-3 sentences\) so it does not feel like overhead. Teams report this reduces persona drift by 60-80% in sessions over 40 turns.
