Fact-Check Pass

Q: How do I know the Fact-Check Pass output is good?

The skill verifies itself against its own 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.

Run a claim-by-claim fact-check pass on a draft article, script, or report before publication. Use when asked to fact-check a piece, verify claims before publishing, or do editorial verification. Produces a claim inventory (every checkable assertion pulled out), a verification status and source for each (confirmed / needs sourcing / unverifiable / wrong), the fixes, and a flag on the high-risk claims (numbers, quotes, names, legal/defamatory statements) that must not go out unverified.

What to give it

▸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

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓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)

⚠️ What it refuses to do

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
