[counterintuitive] More few-shot examples always improve task accuracy

Use 3-5 highly diverse, high-quality few-shot examples; avoid long lists of examples that exceed the model's recency bias window.

Journey Context:
Developers pack prompts with 20\+ few-shot examples hoping to cover edge cases. Models exhibit recency bias, over-indexing on the last few examples, and attention dilution, ignoring the task instructions when overwhelmed by examples. A few highly representative examples outperform many mediocre ones.
