Ask the expert: "what do you notice that a beginner wouldn't?" — this extracts what no manual ever captures.

Show the model 2-5 examples of the desired output style so it mirrors the pattern with high precision.

Separate prompt parts with XML tags (instructions, examples, document) so the model handles each precisely.

In few-shot, deliberate variety (positive/negative/edge case) matters more than count.

Give the model 2-3 complete input-output examples before your ask, instead of explaining the rule verbally.
