python scripts/preflight.py
Run before batch operations to verify API endpoints are reachable.
The format converter (scripts/format-converter.py) uses Python stdlib only — no extra dependencies. Run python scripts/format-converter.py --test to verify the conversion pipeline.
npx claudepluginhub jing1312/nature-figure-skill --plugin nature-skillsMulti-source academic literature search, citation verification, MeSH strategy building, citation file conversion (.nbib/.ris/.bib), and reference management (BibTeX, ID conversion). Useful for coordinated multi-step literature workflows.
Searches PubMed, Semantic Scholar, and bioRxiv/medRxiv with API-verified citations to prevent hallucinations. Generates BibTeX entries for medical research literature.
Searches academic papers across arXiv, PubMed, Semantic Scholar, bioRxiv, medRxiv, Google Scholar, and more. Retrieves BibTeX citations, downloads PDFs, analyzes citation networks for literature reviews and research.
