Report #60880
[frontier] Agent gradually overwrites core safety constraints with user preferences during long sessions
Implement instruction hierarchy tagging with explicit override guards that physically block lower-tier instructions from modifying higher-tier constraints
Journey Context:
Flat prompt structures assume instructions are equally durable; in practice, user messages exhibit position bias and recency effects that overwrite system instructions after 30\+ turns. Hierarchical tagging with hard boundaries \(system/assistant/user tiers\) prevents constraint erosion without sacrificing conversational flexibility, whereas naive repetition wastes tokens and still fails under pressure.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
