Audit a research paper draft (LaTeX sources + .bib) for related work it should cite but does not, above all close prior work that undermines its novelty claims. Searches Semantic Scholar, arXiv, DBLP and Crossref, follows citation graphs, verifies every hit, and produces a prioritized, evidence-backed report plus BibTeX. Use when asked to find missing references/citations, check related-work coverage, test a novelty claim against prior art, do a pre-submission literature check, or anticipate reviewer comments like "the authors overlook X". Not for writing a related-work section from scratch or for formatting a .bib.

Check a BibTeX bibliography against the real published record. Finds fabricated or non-existent references, wrong titles, author lists, DOIs, venues, volumes, pages and years, retracted papers, and arXiv/bioRxiv preprints that have since been published. Use it when asked to check, audit, validate, fact-check, clean up or "fix" a .bib file or reference list, before submitting a paper or thesis, or whenever citations were written or edited by an LLM.

**Run the script, then read its report.** `bibcheck` resolves each entry by a stable identifier first (DOI, arXiv id, then DBLP by title) and compares the record back against the `.bib`, so a fabricated title under a correct DOI is caught. It checks every entry, which a manual pass over a long bibli

**You are the checker.** Measured against the same agent without this skill, careful reading found planted inequality, algebra and dropped-hypothesis errors as often as the skill did, and real slips in unplanted papers at the same rate. What this skill adds is a method for the reading, a hygiene scr
