[counterintuitive] few shot better than zero shot

Start with zero-shot with clear instructions; only add few-shot examples if the model fails to follow the format or logic, as bad examples can drastically degrade performance via context contamination.

Journey Context:
Devs stuff prompts with 5-10 examples thinking it anchors the model. If the examples are slightly off-distribution, too similar, or contain subtle errors, the model will amplify those errors \(few-shot contamination/bias\). Modern instruction-tuned models are highly capable of zero-shot adherence, and few-shot can actually constrain them or teach them bad edge-case behaviors present in the examples.
