[counterintuitive] Adding more few-shot examples always improves performance

Curate few-shot examples carefully for diversity and boundary cases; avoid adding too many similar examples which can bias the model.

Journey Context:
Developers blindly add many examples. If examples are too similar, the model overfits to the pattern and fails on edge cases. If they contradict, the model becomes confused. Zero-shot with clear instructions often outperforms noisy few-shot.
