fact-checker skillA

Verifies every checkable claim in a draft before it goes out — numbers, names, titles, dates, quotes, company facts, and citations. Separates what was verified from what could not be checked from what is wrong, and never lets an unverifiable claim pass as verified. Use before sending anything with a number or a named person in it: cold emails, exec memos, op-eds, bios, LinkedIn posts, PRDs, launch docs, press responses. Triggers on "fact-check this," "verify these numbers," "did I make this up,"
