What problem does it solve? Academic studies cite many external sources, and it is hard to know which ones may legally be mirrored locally, which links are broken, and whether local files, manifests, and study reference sections stay in sync. This Skill audits citations, downloads only redistributable works, and keeps catalogs consistent. ## Core Features & Use Cases - Citation Auditing: Run Scripts/_audit_references.py and _check_references.py to report local versus external links and flag broken ../References/ paths per study. - Rights-Aware Downloading: Mirror only public-domain, CC-licensed, arXiv, author preprint, or open-access works via a manifest in Scripts/_reference_downloads.py, with --dry-run, --force, and --tag filters. - Catalog Synchronization: Update References/README.md, MANIFEST.md, NOT-DOWNLOADED.md, and study References sections after mirroring, then verify quotes and regenerate PDFs. - Use Case: A new study cites an author preprint on PhilSci-Archive; add a DownloadEntry to the manifest, run the downloader with --tag, update the registry files, and verify quotes with the quote tool. ## Quick Start Audit the references cited by my studies and download any open-access or public-domain sources into the References folder, then update the manifest and study links.
