What problem does it solve? Broken bibliography entries, missing local reference files, and bad links inside generated study PDFs are easy to miss when editing academic studies. This Skill runs the repository's reference check suite so citation and link problems are caught before committing bibliography or reference-file changes. ## Core Features & Use Cases - Bibliography and link validation: Checks ## References entries and every ../References/... link in study bodies against local mirror files, flagging empty, corrupt, or bot-wall HTML saved as PDF. - PDF link auditing: Verifies generated study PDFs contain no file:// links and that stable site links resolve to usable sources, with a --skip-pdf option and single-study --study <Slug> filtering. - Companion-note coverage guidance: Explains that canonical suites do not cover technical/research notes, and how to check those bibliographies and PDF annotations directly. - Use Case: After downloading new reference mirrors and editing a study's bibliography, run the suite to confirm every citation resolves, then regenerate affected PDFs before committing. ## Quick Start Ask the assistant to run the reference integrity checks on the study you just edited and report any broken bibliography entries or PDF links.
