literature-search

literature-search is a skill for Claude Code from huifer/drug-discovery-skills. It costs 65 tokens per session (2,021 once invoked), scanned A, original, no licence file.

A literature-search tool for finding research papers in PubMed and preprint databases. Preprints are research manuscripts shared before formal publication, and the tool also summarizes papers and identifies trends.

In plain words
What is it for?
Use it to search biomedical literature, summarize papers, identify key studies, spot research trends, and stay current with new findings.
Why use it?
It helps you find important research and understand large collections of papers without reading every result from scratch. This makes literature reviews and research monitoring easier.

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 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 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/pubmed_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.

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.
