literature-search

literature-search is a skill for Claude Code, Codex from beita6969/ScienceClaw. It costs 90 tokens per session (1,810 once invoked), scanned A, original, MIT.

A planned search workflow that looks across academic databases such as Semantic Scholar, OpenAlex, arXiv, PubMed, and Crossref to build comprehensive bibliographies.

In plain words
What is it for?
Use it to find relevant papers, check the state of research, discover open-access links, and build a bibliography for a review.
Why use it?
It reduces the need to repeat the same search across multiple databases and helps enrich records with citation and publication details.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

literature-search scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Literature Search (Meta Skill)

Orchestrate comprehensive literature searches across multiple databases. Always execute real API calls — never fabricate results or rely on training data.

Priority Order of Databases

  1. Semantic Scholar (PRIMARY) — best relevance ranking, AI TLDR summaries, citation graph
  2. OpenAlex (PRIMARY) — 250M+ works, powerful filtering, open access URLs
  3. arXiv — preprints in physics, math, CS, biology, finance, statistics
  4. PubMed — biomedical and life sciences (NCBI may be unreachable from some networks)
  5. CrossRef — DOI resolution and metadata only (NOT for search — poor relevance ranking)

IMPORTANT: CrossRef search results are poorly ranked by relevance. Never use CrossRef as the primary search engine. Use it only for DOI-based lookups and metadata enrichment.

Mandatory Search Protocol

Every literature search MUST follow this protocol:

Step 1: Semantic Scholar Search (always do this first)

# Primary search — returns papers ranked by relevance with AI summaries
curl -s "https://api.semanticscholar.org/graph/v1/paper/search?\
query=YOUR+SEARCH+TERMS&limit=10&\
fields=title,authors,year,abstract,citationCount,influentialCitationCount,\
isOpenAccess,openAccessPdf,url,externalIds,tldr,venue,publicationDate"

Parse results with:

| python3 -c "
import sys, json
data = json.load(sys.stdin)
print(f'Total: {data[\"total\"]} papers')
for i, p in enumerate(data['data']):
    authors = ', '.join(a['name'] for a in (p.get('authors') or [])[:3])
    if len(p.get('authors') or []) > 3: authors += ' et al.'
    tldr = p.get('tldr', {})
    tldr_text = tldr['text'][:150] if tldr else 'N/A'
    oa = '🔓' if p.get('isOpenAccess') else '🔒'
    doi = (p.get('externalIds') or {}).get('DOI', '')
    print(f'[{i+1}] {p[\"title\"]}')
    print(f'    {authors} ({p.get(\"year\",\"?\")}) — {p.get(\"venue\",\"?\")}')
    print(f'    Cited: {p.get(\"citationCount\",0)} (influential: {p.get(\"influentialCitationCount\",0)}) {oa}')
    print(f'    TLDR: {tldr_text}')
    print(f'    DOI: {doi}')
    print()

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

literature-search is a skill published in the GitHub repository beita6969/ScienceClaw (898 stars, last pushed 3mo ago), licensed MIT. It adds 90 tokens to every session and 1,810 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
