What problem does it solve? When a book, article, or speaker cites a study or quotes a statistic, you often cannot tell whether the claim is real, accurately characterized, or retracted. This Skill traces the claim to its source and records a verdict so you never rely on an unverified citation again. ## Core Features & Use Cases - Claim Tracing: Follows each claim through publication, methodology, raw data availability, and independent replication using databases like Retraction Watch, PubPeer, OSF, Semantic Scholar, and OpenAlex. - Structured Verdicts: Classifies each claim as Verified, Partially verified, Unverifiable, Misattributed, or Retracted, with explicit evidence and caveats. - Brain Page Output: Writes the verification result as a citation-checked brain page under concepts/ so future references reuse the verified analysis. - Use Case: A policy brief claims a program reduced costs by 40% citing a Stanford study. Run this Skill to confirm the paper exists, check whether the data is public, and determine whether the citation accurately represents the findings. ## Quick Start Verify this academic claim from the book by tracing it to the original paper and checking its replication status.
