What problem does it solve? Claims and statistics enter documents, decks, and decisions without anyone verifying where they actually came from. This Skill audits a single source or claim — chasing citation chains to the primary origin, checking what the original actually says versus what is quoted of it, and grading the evidence before you repeat it. ## Core Features & Use Cases - Claim Chasing: Follow citation chains to the primary source, flagging dead ends and repetition masquerading as corroboration. - Incentive and Evidence Audit: Identify funders and conflicts of interest, grade evidence type (measurement vs testimony, replicated vs single-shot), and check denominator discipline and base rates. - Trust Verdicts: Assign a verdict (solid, usable-with-caveats, unverified, debunked) and archive a provenance line with the claim. - Use Case: Before putting "poor code quality costs $85B annually" in an executive deck, trace it to a decade-old vendor extrapolation with no published methodology, mark it unverified, and replace it with your own checkable internal metric. ## Quick Start Fact-check the claim "remote work increases productivity by 47%" before I cite it in my report, tracing it to its primary source and grading the evidence.
