Report #97603

[frontier] Agent's hard safety or business rules erode when long context contains many examples of non-compliant behavior

Limit untrusted in-context demonstrations; classify and sanitize long inputs before they reach the model; prepend a high-authority developer anchor; treat repeated pattern injection as adversarial.

Journey Context:
Anthropic's many-shot jailbreaking research shows that as the number of faux dialogues grows, override success follows a power law. The same in-context learning that improves benign tasks can undermine constraints. Prompt classification cut attack success from 61% to 2% in their experiments.
