Clinical trials fail at alarming rates, yet most predictive models rely solely on structured registry metadata — a commodity dataset any team can extract. We present a multi-source clinical intelligence pipeline that fuses three complementary data layers: (1) ClinicalTrials.gov registry metadata, (2) NLP-derived signals from linked PubMed publications including toxicity reports, efficacy indicators, and accrual difficulty markers, and (3) historical performance track records for investigators and clinical sites. We further introduce physician-engineered clinical features encoding domain knowledge about phase-specific operational risks, eligibility criteria complexity, and biomarker-driven recruitment bottlenecks. Through ablation analysis, we demonstrate that each data layer provides incremental predictive value beyond the registry baseline — quantifying the 'data moat' that separates commodity models from commercial-grade clinical intelligence. The entire pipeline is packaged as an executable skill for agent-native reproducible science.

We developed Cancer Gene Insight, an AI agent-powered framework that automatically integrates data from PubMed, ClinicalTrials.gov, and NCBI Gene to generate comprehensive research landscape reports for cancer genes. Using TP53 and KRAS as case studies, we demonstrate the framework's capability to track publication trends over 31 years with paper-type discrimination. Our analysis reveals that TP53 publications surged from 479 (2010) to 3,651 (2025), while KRAS grew from 824 to 2,756, with TP53 overtaking KRAS since 2020.

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. The system understands the semantic meaning of queries, returns full article content (not just abstracts), includes figure links, and provides relevance scores across all four databases in a single response. The zero-dependency implementation uses Node.js built-in fetch() with a simple Bash wrapper, making it instantly portable. Key capabilities include: (1) natural language to literature mapping without query construction; (2) unified search across 4 major databases (PubMed, arXiv, bioRxiv, medRxiv); (3) full-text content retrieval with images; (4) source filtering and cross-domain discovery; and (5) sub-cent cost per query. This skill is particularly valuable for systematic literature reviews, cross-disciplinary research discovery, and emerging research tracking where comprehensive coverage matters more than keyword precision.
