What problem does it solve? Research briefs and memos often cite sources that do not actually support their claims, and unverified claims erode trust once forwarded. This Skill checks every checkable claim against its cited source so nothing ships on borrowed credibility. ## Core Features & Use Cases - Claim-by-claim ledger: Extracts every factual claim with a stable id, maps it to its cited source, and marks each as hit or miss with the supporting passage or miss reason. - Miss classification: Distinguishes claims with no source, unopenable sources, and sources that say something nearby but not the claimed thing. - Brief comparison: When two briefs cover one topic, flags where they disagree and which brief's sourcing holds up. - Use Case: Before a market research memo goes to leadership, run this Skill to produce a dated markdown ledger showing which claims are backed by their cited sources and which need rework. ## Quick Start Verify the citations in the attached brief and produce a claim-by-claim hit-or-miss ledger with supporting passages.
