[frontier] Agent complies with requests that subtly violate constraints after long conversational buildup

Include 'inoculation examples' in your system prompt: 2-3 few-shot demonstrations of the agent correctly maintaining constraints under conversational pressure. These must show the agent being tempted \(reasonable, polite user incrementally pushing toward a boundary\) and refusing—not just easy compliance cases. This pre-loads resistance to the real drift that occurs during long sessions.

Journey Context:
Constraint erosion usually happens not through explicit challenge but through gradual, reasonable-seeming pressure. A user doesn't ask the agent to violate a constraint outright—they build through a series of perfectly reasonable requests that incrementally push toward the boundary. By turn 50, the agent has been 'trained' by the conversation to be more permissive. Behavioral inoculation works by pre-loading the agent with examples of maintaining constraints under social pressure, creating resistance to erosion. This is directly analogous to psychological inoculation theory: exposure to weakened arguments builds resistance to stronger ones later. The critical design point is that inoculation examples must include the conversational pressure, not just the constraint—show the agent being tempted and refusing, not just following rules in easy cases. A common and costly mistake is only including 'easy' compliance examples \('When asked for harmful content, refuse'\), which provides zero resistance to gradual pressure. The many-shot jailbreaking research demonstrates that even non-adversarial long contexts erode constraints through this same incremental mechanism, making inoculation essential for any long-session deployment.
