[counterintuitive] Providing few-shot examples to teach the model a new task or reasoning pattern

Use zero-shot with detailed instructions for capability; reserve few-shot strictly for demonstrating complex output formatting or edge-case handling.

Journey Context:
Developers often copy 3-5 examples hoping the model will 'learn' the task. With modern frontier models, few-shot examples often hurt performance because the model overfits to the style, length, or even errors of the examples, constraining its native reasoning. Zero-shot with clear instructions leverages the model's full pre-trained capabilities. Few-shot is only valid when you need to show a highly specific, non-standard output schema that is hard to describe textually.
