Fact-Check Pass Skill
Everything in a published piece is a claim someone can be wrong about — a date, a number, a quote, an implication. This skill does what a good fact-checker does: it pulls every checkable assertion out of the prose, verifies each against a source, and stops the high-risk ones (stats, quotes, anything defamatory) from going out on a "probably right."
Working from a brief
Given the draft, produce the claim inventory and status — check what you can against the provided/known sources, and for anything you can't verify, mark it clearly rather than guessing. Never assert a fact is confirmed without a basis.
Required Inputs
Ask for (if not provided, else infer and label):
- The draft (article, script, report)
- Available sources — the reporter's notes, documents, links, transcripts
- Risk level / venue — where it publishes and how litigious/high-stakes the subject is
Output Format
Claim inventory
Every checkable assertion extracted:
| # | Claim (as written) | Type | Status | Source / basis | Fix |
|---|
- Type: number/stat · quote · name/title · date · causal/implied · characterization.
- Status: ✅ confirmed · 🟡 needs sourcing · ⚠️ unverifiable · 🔴 wrong/misleading.
High-risk flags
The claims that must not publish unverified — statistics, direct quotes and their attribution, named individuals (especially any allegation), superlatives ("first," "only," "largest"), and anything potentially defamatory. Each with what's needed to clear it.
Fixes
For every 🔴/⚠️: the correction, a hedge to the supportable version, or "cut it." For 🟡: the source to obtain.
Sign-off
What's still open before this can publish, and a note that quotes should be confirmed with the speaker/transcript and legal review sought for anything defamatory.
Quality Checks
- Every checkable claim is inventoried, not just the obvious ones
- Each claim has a status and a named source/basis (or is marked unverifiable)
- Numbers, quotes, names, and superlatives are treated as high-risk and flagged
- Potentially defamatory statements are flagged for verification and legal review
- Nothing is marked confirmed without an actual basis
- Every problem claim has a concrete fix (correct / hedge / cut)
Anti-Patterns
- Reading for tone instead of extracting discrete claims
- Marking something "confirmed" on memory or vibes
- Letting a round number or a paraphrased quote through unchecked
- Missing implied/causal claims because they're not stated as facts
- Waving through a defamatory line without verification or legal input
- Rewriting the prose instead of flagging and sourcing the facts
