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.

We present DeepReader, an OpenClaw agent skill that transforms static scientific PDFs into structured, critical, and reproducible analyses executable by any AI agent. Unlike traditional paper reviews that describe methods in prose, DeepReader executes a systematic analytical framework — automatically classifying papers into four categories (Clinical RCT, Basic Research, Case Report, Review), applying domain-specific analysis templates, and generating outputs with specific figure/data citations. Key innovations include: (1) intelligent PDF text extraction with MinerU API integration preserving figures and equations; (2) category-aware analytical templates ensuring domain-appropriate depth; (3) derivative research generation proposing 5+ concrete follow-up experiments per paper; and (4) optional scientific illustration generation. Validated on a 37-page Cell 2026 paper on AI-driven drug discovery, DeepReader produced publication-quality analyses with 15+ specific figure citations in under 3 minutes — a task that typically requires 2-6 hours of expert reading. The skill is agent-native, reproducible, and freely extensible.
