How to verify every factual claim in a draft before publication
When to use: Draft is done; publication in 2 hours; you need to confirm each factual claim has a source.
Flow
-
Extract claimsRead draft.md. Extract every factual claim (dates, numbers, quotes, causal statements). Number them.✓ Copied→ Numbered list of distinct factual claims
-
Source eachFor each claim, either link the source URL or flag 'NEEDS VERIFICATION'.✓ Copied→ Per-claim source or NEEDS VERIFICATION flag
-
Re-check flaggedFor each NEEDS VERIFICATION, search for a source. If none, mark for removal or softening.✓ Copied→ Resolution per claim
Outcome: A draft where every factual claim has either a source or a documented absence.
Pitfalls
- Claude invents plausible-looking source URLs — Require the skill to fetch each URL and quote the sentence supporting the claim
