What problem does it solve? Researchers need to summarize gene or protein evidence from multiple public databases without losing track of which claim came from which source, and without overstating what abstracts or curated records actually support. ## Core Features & Use Cases - Multi-source evidence retrieval: Queries UniProt for curated protein records and PubMed, Europe PMC, or arXiv for literature, matching the source to the research question. - Claim-to-source traceability: Attaches a canonical clickable citation (PMID, UniProt accession, arXiv ID) to every substantive claim and separates curated annotations from individual-paper findings. - Structured deliverables: Produces an evidence_brief.md and sources.json with retrieval metadata, limitations, and next evidence needed. - Use Case: Ask for a summary of a human gene's function; the Skill retrieves the reviewed UniProt entry, scans recent literature, and returns a cautious brief with a claim-to-source table and references. ## Quick Start Use the life-science-evidence-brief skill to research the function of human TP53 and produce a cited evidence brief with sources saved to files.
