Pull arXiv and Semantic Scholar literature—with citation chains and PDF-to-markdown extraction—for reviews before you build ML features or write technical content.
About
papers is an agent research skill in the Claude Night Market / Tome family that searches academic literature through arXiv, Semantic Scholar, Unpaywall, CORE.ac.uk, PubMed Central, and author preprint pages when you need citations, formal methods, or literature reviews—not forum opinions or GitHub implementations. It orders sources for free metadata first, uses Semantic Scholar where citation graphs matter, and routes PDFs through the leyline document-conversion protocol: try markitdown’s convert_to_markdown for structured tables and equations, then fall back to paginated Read if MCP is unavailable. Triggers include building citation chains, surveying a niche before committing to an ML-heavy validate prototype, or grounding launch and grow content in citable papers. The skill explicitly deflects community takes to discourse skills and implementations to code-search, which keeps Prism journey placement honest. Solo builders wire it into Claude Code-style stacks when agent tooling must cite primary research instead of hallucinated references.
- Six-source priority stack: arXiv, Semantic Scholar, Unpaywall, CORE, PubMed Central, author preprints
- Semantic Scholar citation graphs (documented 100 req / 5 min)
- Explicit When NOT To Use: discourse vs code-search skills
- PDF pipeline prefers markitdown MCP convert_to_markdown, then Read-tool fallback
- Depends on leyline:document-conversion protocol (~350 estimated tokens in metadata)

What it does
Pull arXiv and Semantic Scholar literature—with citation chains and PDF-to-markdown extraction—for reviews before you build ML features or write technical content.
Files
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 increments as needed
- Note: tables and figures will not extract as cleanly
Extraction Targets
From the converted markdown, extract:
- Abstract and key findings
- Methodology and experimental setup
- Results tables and figures
- Citation information (authors, year, venue)
- Key equations or formal definitions
Fallback Guidance
When a paper is paywalled and no open version exists:
- Public library JSTOR/ProQuest access via library card
- DeepDyve article rental
- Inter-library loan request
- Direct author email template
Exit Criteria
- [ ] At least one academic source queried in priority order
(arXiv first, then Semantic Scholar, then Unpaywall/CORE/PubMed)
- [ ] PDF content converted via
leyline:document-conversion
protocol: markitdown MCP attempted first, Read-tool fallback used if markitdown is unavailable
- [ ] Each paper result includes citation info (authors, year, venue)
and an abstract or key findings summary
- [ ] Paywalled papers with no open version trigger the fallback
guidance (library, DeepDyve, ILL, author contact) rather than returning an empty result
- [ ] If all sources return zero results, this is stated explicitly
rather than generating fabricated paper entries
