If you're querying biomedical literature, this hooks Claude Code directly into PubMed and NCBI E-utilities instead of relying on general web search. It handles MeSH term queries, field tags, date ranges, and PMID lookups, which matters when you need repeatable search strings for systematic reviews or meta-analyses. The skill walks through proper query construction by breaking research questions into concepts and combining them with Boolean operators. With 1.1K installs and passing three security audits, it's become a go-to for anyone doing literature reviews or pulling citation metadata programmatically. Saves you from manually formatting E-utilities HTTP requests or wrestling with PubMed's web interface when you just want abstracts and publication data in your workflow.
