[frontier] Agent behavioral constraints weaken when context accumulates many examples of different behavior pattern

Monitor the example ratio — the count of turns demonstrating off-spec behavior vs. on-spec behavior. When off-spec examples exceed a threshold \(emerging heuristic: 5-7 consecutive off-spec turns\), inject a system-level pattern break: a fresh exemplar demonstrating the correct behavior, framed as a context update rather than a correction.

Journey Context:
Anthropic's many-shot jailbreaking research demonstrated that many in-context examples of a behavior can override model training. The same principle applies to instruction following: accumulated turns of slightly off-spec behavior \(due to user framing, ambiguity, or early drift\) compound and become the de facto instruction. The model treats its own prior responses as a stronger signal than the original system prompt. The emerging practice is monitoring the 'example ratio' and inserting pattern breaks before the override threshold. A pattern break is not just a reminder — it's a fresh exemplar that demonstrates the correct behavior, resetting the accumulated off-spec pattern. The tradeoff is that pattern breaks can feel discontinuous to the user, so they must be framed as natural context updates \('Updating my approach based on project context...'\) rather than corrections \('I was drifting, let me reset'\). The critical nuance: reminders without exemplars don't work. The model needs to see the desired behavior pattern, not just be told about it.
