[gotcha] Model becomes compliant after a long sequence of benign-looking examples

Limit the number of in-context examples, especially when they come from user-controlled sources. Monitor context windows for repeated harmful patterns and apply output filtering to generated responses, not just the input. Use classifiers that detect harmful outputs regardless of how the context was primed.

Journey Context:
People think one or two safety examples will not matter, but models are few-shot learners. An attacker can prepend dozens or hundreds of subtly harmful Q&A pairs before the target query. The model treats the pattern as a continuation task and bypasses safety training. Defending only the final user turn misses the attack because the jailbreak is distributed across the whole context.
