[counterintuitive] Providing 3-5 input/output examples to teach the model a specific output format

Use zero-shot prompting with native structured output schemas \(JSON mode / Structured Outputs / tool use\) instead of few-shot examples.

Journey Context:
Few-shot was essential when models struggled with formatting. Now, few-shot examples often conflict with the model's native capabilities or strict JSON schemas, leading to unpredictable behavior. If you use Structured Outputs \(JSON schema\), few-shot examples are not only redundant but can actively confuse the schema adherence. Zero-shot \+ schema is more robust, token-efficient, and guarantees the output type.
