biomedical-search

biomedical-search is a skill for Claude Code from yorkeccak/scientific-skills. It costs 30 tokens per session (1,418 once invoked), scanned B, original, MIT.

A search tool covering biomedical sources such as PubMed, bioRxiv and medRxiv preprints, clinical-trial records, and FDA drug labels. It accepts ordinary-language questions and combines results from these sources.

In plain words
What is it for?
Use it to find research papers, early results, clinical trials, and official drug-label information for a biomedical question.
Why use it?
It gives you one place to search different kinds of biomedical evidence instead of checking each database separately.

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 B, and why

biomedical-search scanned grade B 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 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/search.mjs), 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 — 215 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Search across all major biomedical databases (PubMed, bioRxiv, medRxiv, ClinicalTrials.gov, FDA drug labels) simultaneously using natural language queries powered by Valyu's semantic search API.

Why This Skill is Powerful

  • No API Parameter Parsing: Just pass natural language queries directly - no need to construct complex search parameters
  • Semantic Search: Understands the meaning of your query, not just keyword matching
  • Full-Text Access: Returns complete content from literature, trials, and drug labels
  • Image Links: Includes figures and images when available
  • Comprehensive Coverage: Search across PubMed, bioRxiv, medRxiv, clinical trials, and drug labels simultaneously
  • Unified Results: Get results from all biomedical sources in a single query

Requirements

  1. Node.js 18+ (uses built-in fetch)
  2. Valyu API key from https://platform.valyu.ai ($10 free credits)

CRITICAL: Script Path Resolution

The scripts/search commands in this documentation are relative to this skill's installation directory.

Before running any command, locate the script using:

BIOMEDICAL_SCRIPT=$(find ~/.claude/plugins/cache -name "search" -path "*/biomedical-search/*/scripts/*" -type f 2>/dev/null | head -1)

Then use the full path for all commands:

$BIOMEDICAL_SCRIPT "CAR-T cell therapy" 20

API Key Setup Flow

When you run a search and receive "setup_required": true, follow this flow:

  1. Ask the user for their API key: "To search biomedical databases, I need your Valyu API key. Get one free ($10 credits) at https://platform.valyu.ai"

  2. Once the user provides the key, run:

    scripts/search setup <api-key>
    
  3. Retry the original search.

When to Use This Skill

  • Complete biomedical information gathering
  • Clinical research combined with basic science
  • Finding trials, literature, and official drug info together
  • Evidence-based medicine research
  • Disease understanding from multiple angles

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.

biomedical-search is a skill published in the GitHub repository yorkeccak/scientific-skills (61 stars, last pushed 7mo ago), licensed MIT. It adds 30 tokens to every session and 1,418 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
