biomedical-literature-search

biomedical-literature-search is a skill for Claude Code, Codex from PharMolix/OpenBioMed. It costs 75 tokens per session (918 once invoked), scanned A, original, MIT.

A research tool for finding biomedical papers in PubMed, a database of medical and life-science publications, and bioRxiv, a server for sharing biomedical preprints before peer review. It retrieves titles, abstracts, authors, and links.

In plain words
What is it for?
Use it to find papers on diseases, treatments, or drug discovery topics, retrieve recent biomedical preprints, and gather material for a literature review.
Why use it?
It reduces the time spent searching separate literature databases and collecting paper details by hand.

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

biomedical-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 13d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (examples/basic_example.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Search PubMed and bioRxiv for biomedical research papers with titles and abstracts.

When to Use

  • Find research papers on a specific biomedical topic
  • Retrieve recent preprints from bioRxiv
  • Get paper titles, abstracts, authors, and links
  • Literature review for drug discovery or biomedical research

Workflow

PubMed Search (Keyword-based)

import requests
import xml.etree.ElementTree as ET

# Step 1: Search for PMIDs
search_url = "https://eutils.ncbi.nlm.nih.gov/entrez/eutils/esearch.fcgi"
params = {"db": "pubmed", "term": "PD-1 inhibitor cancer", "retmax": 10, "retmode": "json"}
response = requests.get(search_url, params=params)
pmids = response.json()["esearchresult"]["idlist"]

# Step 2: Fetch paper details
fetch_url = "https://eutils.ncbi.nlm.nih.gov/entrez/eutils/efetch.fcgi"
response = requests.get(fetch_url, params={"db": "pubmed", "id": ",".join(pmids), "rettype": "abstract", "retmode": "xml"})

bioRxiv Fetch (Date-range based)

import requests

# Fetch papers by date range
url = "https://api.biorxiv.org/details/biorxiv/2026-02-01/2026-03-01"
response = requests.get(url)
papers = response.json()["collection"]

for paper in papers[:5]:
    print(f"Title: {paper['title']}")
    print(f"Abstract: {paper['abstract'][:200]}...")

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
