Literature Search (Meta Skill)

Orchestrate comprehensive literature searches across multiple databases. Always execute real API calls — never fabricate results or rely on training data.

Priority Order of Databases

1. Semantic Scholar (PRIMARY) — best relevance ranking, AI TLDR summaries, citation graph
2. OpenAlex (PRIMARY) — 250M+ works, powerful filtering, open access URLs
3. arXiv — preprints in physics, math, CS, biology, finance, statistics
4. PubMed — biomedical and life sciences (NCBI may be unreachable from some networks)
5. CrossRef — DOI resolution and metadata only (NOT for search — poor relevance ranking)

IMPORTANT: CrossRef search results are poorly ranked by relevance. Never use CrossRef as the primary search engine. Use it only for DOI-based lookups and metadata enrichment.

Mandatory Search Protocol

Every literature search MUST follow this protocol:
