What problem does it solve? Keeping a personal research paper library organized is tedious: papers arrive as DOIs, URLs, or PDFs, metadata is often incomplete, and exporting clean BibTeX for manuscripts requires manual cleanup. This Skill operates the pzi CLI to add, search, tag, validate, and export entries in a local BibTeX library. ## Core Features & Use Cases - Add papers from any source: Add entries by DOI, URL, or PDF, in bulk from files or an inbox, with idempotent behavior that avoids duplicates. - Search and export: Query by keyword, author, or year, inspect full records by citekey, and export the library as BibTeX or JSON. - Metadata maintenance: Validate citations with strict checks, fill missing metadata, promote preprints to published versions, dedupe, and manage orphan PDFs. - Use Case: Before submitting a paper, run a strict library check to audit citation metadata, promote any preprints to their published versions, and export the final BibTeX file. ## Quick Start Add the paper with DOI 10.1145/example to my pzi library, tag it as systems, and export the updated BibTeX.
