The instructions your agent reads when the skill is triggered.

Clinical Trials Search

Search the complete ClinicalTrials.gov database of clinical studies 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 trial information including phases, conditions, interventions, and outcomes
Image Links: Includes data visualizations when available
Comprehensive Coverage: Access to all ClinicalTrials.gov data

Requirements

Node.js 18+ (uses built-in fetch)
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:

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

Then use the full path for all commands:

$CLINICAL_TRIALS_SCRIPT "CAR-T cell therapy trials" 15

API Key Setup Flow

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

Ask the user for their API key: "To search ClinicalTrials.gov, I need your Valyu API key. Get one free ($10 credits) at https://platform.valyu.ai"
Once the user provides the key, run:
```
scripts/search setup <api-key>
```
Retry the original search.

When to Use This Skill

Adding to Your Project

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

Python Integration

from valyu import Valyu

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

response = client.search(
    query="your search query here",
    included_sources=["valyu/valyu-clinical-trials"],
    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

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-clinical-trials"],
  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.
