[counterintuitive] Should I always add few-shot examples to prompts

Start with zero-shot with detailed instructions. Add few-shot only if zero-shot fails, or if the task requires a highly specific output format that is difficult to describe textually.

Journey Context:
Developers reflexively add 3-5 examples to every prompt, assuming examples are the best way to teach the model. For modern, highly capable models, few-shot can constrain the model too much, causing it to mimic the style or surface-level patterns of the examples rather than solving the actual underlying logic. Zero-shot with detailed instructions often outperforms few-shot on complex reasoning tasks.
