- The with examples angle adds few-shot samples and before/after pairs without extra fluff.
- Asks for a self-check pass, which cuts hallucinated details.
How to use it in Claude

Keep that context in the thread when you iterate. Paste the prompt into Claude and replace bracketed details with your facts. When experimenters review output, they should see few-shot samples and before/after pairs without hunting for it. Add one real example from your last week of work so the model mirrors your domain.

- Open Claude and paste the prompt block unchanged.
- Replace placeholders with your project facts (experimenters, offer, timeline).
- Confirm the constraint is still visible: sample and metric.
- Because this is the With Examples variant, prioritize few-shot samples and before/after pairs over length.
- Reply with one fix list, then regenerate the final version only.
Example output
Example output shape: H1 with A/B Test Plan, 3 short sections, bullet list of recommendations, closing line that states sample and metric. Facts you supply appear; nothing invented.
Common mistakes
- Using the With Examples prompt but editing it into a vague one-liner.
- Deleting "sample and metric" to save space — that is usually the whole point.
