[frontier] Agent personality drifts from 'expert critic' to 'agreeable assistant' over 50\+ turns

Deploy Adversarial Identity Re-assertion: every 12-15 turns, inject a synthetic 'devil's advocate' user message that challenges the agent's recent conclusions with plausible but incorrect reasoning, forcing the agent to re-derive its position from first principles. Immediately following the agent's response, prepend a system message re-stating the core identity \('You are a skeptical expert who prioritizes accuracy over agreement'\).

Journey Context:
Long conversations create 'path dependence' where the model optimizes for conversational coherence and user satisfaction \(sycophancy\) over the original expert persona. Simply adding 'Remember to be critical' to the system prompt fails because the immediate conversational momentum overrides static instructions. The adversarial injection artificially creates a 'discontinuity' that breaks the sycophancy feedback loop. By forcing the agent to defend against a challenge, it activates 'defensive reasoning' modes that are more critical. The immediate follow-up identity reinforcement then 'anchors' this re-activated persona before the next real user turn. This mimics the 'fresh eyes' effect in human peer review. Tradeoff: uses extra tokens and requires careful crafting of adversarial prompts to avoid confusing the user \(should be marked as \[internal simulation\] or similar\).
