Prompt / template

<draft>[paste]</draft>
<sources>[paste the source documents or notes the draft is based on]</sources>
List every factual claim in the draft (numbers, dates, names, quotes, cause-and-effect statements). For each one, say whether <sources> supports it, contradicts it, or doesn't mention it, and quote the supporting line. If you can't find support, say "not supported"; don't guess. Finish with the claims I must verify or remove before publishing.
