[counterintuitive] Zero-shot is sufficient now that models are instruction-tuned

Use zero-shot for familiar formats, but add 1-2 strong examples when the task requires format fidelity, domain-specific judgment, or avoiding common failure modes. Treat examples as specification, not training data.

Journey Context:
The pendulum swung from 'always use few-shot' to 'zero-shot is enough because instruction tuning is so good.' Neither extreme is right. Modern models are excellent zero-shot generalists, but they still benefit from examples when the desired output is unusual, when there is a known ambiguity, or when the cost of a format error is high \(e.g., generating a migration script, a legal clause, or a structured log entry\). The key is that examples should be used sparingly and as part of the specification, not as a substitute for clear instructions. A single high-quality example often beats a long explanation.
