Report #24948

[synthesis] Model drops its system persona or constraints when provided with many few-shot examples that slightly contradict the rules

If using few-shot examples, ensure they are perfectly consistent with the system prompt. For Claude, place the system constraints after the few-shot examples, or repeat the core constraint at the end of the prompt.

Journey Context:
Claude is highly susceptible to being 'distracted' by few-shot examples, overriding the system prompt if the examples imply a different format. GPT-4o is more robust to few-shot overrides but might mimic the tone of the examples too closely. Recency bias in attention mechanisms means the model weighs examples heavily; reinforcing constraints after the examples anchors the model back to the desired behavior.
