bib-check-agent
Checks every entry in a LaTeX .bib file against Semantic Scholar, DBLP, Crossref, arXiv, OpenAlex, Europe PMC and other open databases, and Google Scholar with the user's help, then researches and fixes the problems, with every fix independently re-checked. Catches hallucinated or made-up citations, wrong authors, years or venues, broken DOIs or arXiv IDs, duplicate entries, and citations that don't support the sentence citing them. Use it whenever the user wants to check, verify, validate, audit, fix or clean up references, citations, a bibliography or a .bib file, or worries that citations might be fake, even if they don't name this skill.
