What it does

Biomedical Search is an agent skill from wu-yc/LabClaw. Complete biomedical information search combining PubMed, preprints, clinical trials, and FDA drug labels. Powered by Valyu semantic search.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Research & Science, covering Academic paper search and Clinical and healthcare research. It works with PubMed. The repository describes itself as: LabClaw – Operating Layer for LabOS (Stanford-Princeton AI Co-Scientists). The licence is MIT.

When your agent uses it

  • Tasks that involve Academic paper search
  • Tasks that involve Clinical and healthcare research

Example prompts

  • “/biomedical-search”

Requirements

  • Python 3
  • Node.js

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

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

What it can do on your machine

Read from SKILL.md and the folder at commit df37802. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • jq

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • api.valyu.ai

    Also links to:

    • platform.valyu.ai
    • docs.valyu.ai

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Biomedical Search loads about 1.4k tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 337 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~39
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Complete biomedical information search combining PubMed, preprints, clinical trials, and FDA drug labels. Powered by Valyu semantic search.

license

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:

bash
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:

bash
$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:

    bash
    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

Adding to Your Project

If you're building an AI project and want to integrate Biomedical Search directly into your application, use the Valyu SDK:

Python Integration
python
from valyu import Valyu

client = Valyu(api_key="your-api-key")

response = client.search(
    query="your search query here",
    included_sources=["valyu/valyu-pubmed", "valyu/valyu-biorxiv", "valyu/valyu-medrxiv", "valyu/valyu-clinical-trials", "valyu/valyu-drug-labels"],
    max_results=20
)

for result in response["results"]:
    print(f"Title: {result['title']}")
    print(f"URL: {result['url']}")
    print(f"Content: {result['content'][:500]}...")
TypeScript Integration
typescript
import { Valyu } from "valyu-js";

const client = new Valyu("your-api-key");

const response = await client.search({
  query: "your search query here",
  includedSources: ["valyu/valyu-pubmed", "valyu/valyu-biorxiv", "valyu/valyu-medrxiv", "valyu/valyu-clinical-trials", "valyu/valyu-drug-labels"],
  maxResults: 20
});

response.results.forEach((result) => {
  console.log(`Title: ${result.title}`);
  console.log(`URL: ${result.url}`);
  console.log(`Content: ${result.content.substring(0, 500)}...`);
});

See the Valyu docs for full integration examples and SDK reference.

Can I use Biomedical Search in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add wu-yc/LabClaw --skill biomedical-search -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/biomedical-search, .gemini/skills/biomedical-search, .github/skills/biomedical-search and .opencode/skills/biomedical-search in your project.

What does Biomedical Search need to run?

Going by SKILL.md and its folder, Biomedical Search needs the command-line tools its instructions call (jq). Our summary lists: Python 3; Node.js.

Does Biomedical Search access the network?

SKILL.md names 3 domains. In commands or code: api.valyu.ai; the agent is likely to contact it when it follows the instructions. As links in the text: platform.valyu.ai and docs.valyu.ai. This is read from the text; nothing was executed.

Is Biomedical Search safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Biomedical Search use?

Biomedical Search is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Biomedical Search use?

About 1.4k tokens (SKILL.md is roughly 5.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Biomedical Search?

Skills that share tags, products or a category with Biomedical Search: Medical Research Toolkit (FreedomIntelligence/OpenClaw-Medical-Skills, 3.1k stars), Pubmed Database (google-deepmind/science-skills, 3.2k stars), Meta Feasibility Analyzer (aipoch/medical-research-skills, 1.9k stars) and Baseline Extraction For Clinical Trials (aipoch/medical-research-skills, 1.9k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
