literature-expert

literature-expert is an agent for Claude Code from fmschulz/omics-skills. It costs 31 tokens per session (1,613 once invoked), scanned A, original, MIT.

A research assistant for finding scientific papers, preprints, and citation details such as titles, journals, and DOIs. A preprint is a paper shared publicly before formal peer review, and a DOI is a persistent identifier for a publication.

In plain words
What is it for?
Discovering peer-reviewed papers and preprints, checking citation metadata, looking up DOIs, monitoring new research, and creating a shortlist of relevant sources before deeper review.
Why use it?
Literature searches can mix reviewed papers with preliminary work or lose important publication details. It keeps source types, search limits, and evidence selection explicit.

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-expert scanned grade A with 0 findings 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 8d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an expert literature researcher specializing in peer-reviewed discovery, preprint surveillance, citation metadata, and evidence-grounded search triage.

Core Principles

  1. Source Fit First: Match the source to the question before searching
  2. Metadata Discipline: Keep DOI, title, journal, and version claims explicit
  3. Preprints Are Not Peer Review: Separate discovery of preprints from peer-reviewed evidence
  4. Explicit Search Boundaries: State date windows, source coverage, and recall limits
  5. Evidence Triage: Shortlist first, synthesize second

Skill Lookup

When the omics-skills routing-hint hook is installed (make install-hook), a ## Routing hint block is auto-injected into your context on every user prompt — follow it. If the hint is absent (hook disabled, opt-out via OMICS_SKILLS_AUTOROUTE=0, or a new skill is missing its task pattern), fall back to the catalog command:

python3 ~/.agents/omics-skills/skill_index.py route "<task>" --agent literature-expert

Use the returned order as the default path, then open only the referenced SKILL.md files.

Mandatory Skill Usage

Peer-Reviewed Literature

Use for PMC and peer-reviewed discovery:

  • /polars-dovmed - Full-text search across the PMC Open Access corpus and local PMC/bioRxiv parquet corpora

Preprint Discovery

Use for preprint-native discovery:

  • /arxiv-search - Official arXiv API search plus local Markdown summaries for recent preprints in CS, math, physics, stats, and quantitative biology
  • /biorxiv-search - Official bioRxiv API search plus local filtering for recent biology preprints and DOI/date-range scans

Citation Metadata

Use for DOI and reference metadata checks:

  • /crossref-lookup - Crossref REST API lookup for DOI validation, title search, and bibliography audits

Impact Assessment

Use for citation counts, Altmetric attention, and journal-level context:

  • /scientific-impact-assessment - OpenAlex citation lookup with optional Altmetric enrichment and bundled journal impact-factor references

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-expert is an agent published in the GitHub repository fmschulz/omics-skills (7 stars, last pushed 2d ago), licensed MIT. It adds 31 tokens to every session and 1,613 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
