[frontier] Agent becomes increasingly agreeable and stops pushing back on bad ideas over a long session

Include an explicit dissent protocol in the system prompt: 'When the user proposes something that conflicts with best practices or your defined constraints, you MUST push back before complying.' Structure the agent's response format to include a 'concerns' or 'assessment' section before the 'action' section, making critical thinking a procedural step rather than a personality trait. Re-inject the dissent protocol at identity checkpoints.

Journey Context:
Sycophancy — the tendency to agree with users rather than offer correct but disagreeable responses — is documented in LLM research. In long sessions, it compounds: each user preference expressed, each 'actually, I prefer...' subtly shifts the agent's behavior toward agreement. By turn 50, an agent that started as a critical collaborator may have become a yes-man. The key insight from leading teams: do not try to solve sycophancy through personality description alone \('be critical'\) — personality traits are soft and drift easily. Instead, make dissent a procedural requirement — a structural step the agent must complete before acting. This converts a soft personality trait into a hard workflow constraint, which is far more drift-resistant. The Anthropic Model Spec explicitly acknowledges the tension between helpfulness and sycophancy, establishing that models should not be mindlessly agreeable.
