What problem does it solve? Blog posts often contain statistics and claims that are misquoted, outdated, or unsupported by their cited sources, and manually checking every link is slow and error-prone. This Skill automates claim extraction and source verification so you can publish with confidence. ## Core Features & Use Cases - Claim Extraction: Identifies all load-bearing claims including statistics, product, policy, ranking, comparative, and legal statements, with or without citations. - Source Verification: Validates and fetches cited URLs safely, classifies sources into quality tiers (T1-T5), detects echo clusters, and scores each claim from VERIFIED (1.0) to NOT FOUND (0.0). - Verification Report: Produces a structured report with per-claim scores, flags uncited claims as UNVERIFIED with suggested search queries, and lists recommended actions. - Use Case: Before publishing a marketing blog post citing "73% of marketers use AI (HubSpot, 2025)", run this Skill to confirm the statistic actually appears on the cited page and flag any claims lacking sources. ## Quick Start Ask the AI to fact check your blog post file, for example by saying: fact check the claims and sources in my draft post at content/blog/q3-trends.md.
