Pubmed Database

Direct HTTP access to PubMed's E-utilities REST API for systematic literature searches and citation management. You'll use this when you need to construct complex Boolean queries with MeSH terms, pull batches of abstracts programmatically, or build automated literature monitoring workflows. The skill covers search syntax (field tags like [mh] for MeSH, [tiab] for title/abstract), all the core E-utilities endpoints (ESearch, EFetch, ESummary), and practical patterns for systematic reviews using PICO frameworks. If you're doing Python work, the docs suggest using biopython's Bio.Entrez instead. This is for raw REST calls or custom implementations where you need control over the HTTP layer.
