pubmed

pubmed is a skill for Claude Code from 0xmariowu/Autosearch. It costs 27 tokens per session (324 once invoked), scanned A, original, MIT.

A search connector for PubMed, the free database of biomedical and life-science research from the U.S. National Library of Medicine. It finds medical papers, clinical trials, drug studies, and biological research.

In plain words
What is it for?
Use it to find medical journal articles, clinical trials, drug research, abstracts, DOIs, and PubMed identifiers.
Why use it?
It provides a focused way to locate biomedical literature and publication details for research-backed answers.

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

pubmed 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 10d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (__init__.py, methods/api_search.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.

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.

What it actually says

Overview

PubMed is NCBI's free search engine for biomedical and life sciences literature. No API key required. Best for medical research, clinical trials, drug studies, and biological science papers.

When to Choose It

  • Biomedical, clinical, or pharmaceutical research queries
  • Searching for peer-reviewed medical journal articles
  • Finding abstracts with DOI or PubMed ID for citation

Uses E-utilities API: esearch.fcgi to get IDs, esummary.fcgi to fetch metadata.

Quality Bar

  • Evidence items have non-empty title and url.
  • No crash on empty or malformed API response.
  • Source channel field matches the channel name.
Files

What ships with it

2 files 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.
