Profile →npx skills add majiayu000/claude-skill-registry --skill papers --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Academic Papers Search ## When To Use - Finding academic papers, citations, or formal research - Building literature reviews or citation chains ## When NOT To Use - Community opinions (use `/tome:discourse`) - Code implementations (use `/tome:code-search`) Search arXiv, Semantic Scholar, and open-access sources. ## Sources (Priority Order) 1. arXiv API (free, unlimited metadata) 2. Semantic Scholar API (100 req/5min, citation graphs) 3. Unpaywall (legal free version discovery) 4. CORE.ac.uk (open-access aggregator) 5. PubMed Central (biomedical) 6. Author preprint pages (WebSearch fallback) ## PDF Processing After acquiring a paper URL or local file path, convert the PDF to markdown for better extraction quality. ### Conversion (prefer markitdown) Apply the `leyline:document-conversion` protocol: 1. **Try markitdown first**: call the MCP `convert_to_markdown` tool with the PDF URL or `file://` path. This produces structured markdown preserving tables, equations, figures, and section hierarchy. 2. **Fall back to Read tool** if markitdown is unavailable: - Read with `pages: "1-20"` for the first chunk - Continue with `pages: "21-40"` for longer papers - Continue in 20-page incremen

What does the papers skill do?
Search academic literature via arXiv, Semantic Scholar, and open-access PDFs.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill papers --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
