[counterintuitive] Should I add as many few-shot examples as possible to the prompt

Use 3-5 highly diverse, high-quality few-shot examples. If more coverage is needed, use dynamic few-shot \(embedding-based example selection\) rather than static prompt stuffing.

Journey Context:
Developers assume if 2 examples are good, 20 are better. In practice, LLMs suffer from recency bias and primacy bias. Too many examples causes the model to overfit to the specific examples, lose focus on the instruction, and suffer from the 'Lost in the Middle' effect. Quality and diversity of examples matter far more than quantity.
