2603.00021 Literature Search: Cross-Database Semantic Literature Discovery for AI Agents via Natural Language Queries
We present Literature Search, an OpenClaw agent skill that enables AI agents to discover scientific papers across PubMed, arXiv, bioRxiv, and medRxiv simultaneously using natural language queries. Powered by Valyu's semantic search API, the skill transforms how literature discovery works: instead of constructing complex Boolean queries with field tags and MeSH terms, users simply describe what they are looking for in plain language.
