[counterintuitive] Providing 3-5 complex few-shot examples to teach a task to modern frontier models

Use zero-shot with highly explicit instructions and structured output schemas first; only add 1-2 minimal few-shot examples if the output format is highly unintuitive or to demonstrate a specific edge case.

Journey Context:
Few-shot was essential for base models like GPT-3 because they couldn't follow zero-shot instructions. With modern instruction-tuned models, few-shot examples often conflict with the system prompt or each other, and consume massive context windows. If the examples have a subtle flaw, the model will amplify it. Zero-shot with clear schemas is more robust and leaves context for the actual task.
