clinical-trials-searchSearch ClinicalTrials.gov with natural language queries. An agent skill from wu-yc/LabClaw.
Clinical Trials Search is an agent skill from wu-yc/LabClaw. Search ClinicalTrials.gov with natural language queries. Find clinical trials, enrollment, and outcomes using Valyu semantic search.
Its SKILL.md is about 1.3k 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 Clinical and healthcare research. The repository describes itself as: LabClaw – Operating Layer for LabOS (Stanford-Princeton AI Co-Scientists). The licence is MIT.
2 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit df37802. It shows what the files ask for, not the result of running them.
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.
Shell commands in SKILL.md call:
jqFrom the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
api.valyu.aiclinicaltrials.govAlso links to:
platform.valyu.aidocs.valyu.aiFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Clinical Trials Search loads about 1.3k tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 317 words of instructions outside code blocks.
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.
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.

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" 15When 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.

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

Search ClinicalTrials.gov with natural language queries. An agent skill from wu-yc/LabClaw. Clinical Trials Search is an agent skill from wu-yc/LabClaw.gov with natural language queries.
Clinical Trials Search fits situations like: tasks that involve Clinical and healthcare research.
Run `npx skills add wu-yc/LabClaw --skill clinical-trials-search -a claude-code`. Or copy the skill folder (skills/literature/clinical-trials-search in wu-yc/LabClaw) into .claude/skills/clinical-trials-search in your project. Claude Code loads it when a task matches its description.
Run `npx skills add wu-yc/LabClaw --skill clinical-trials-search -a codex`. Or copy the skill folder (skills/literature/clinical-trials-search in wu-yc/LabClaw) into .agents/skills/clinical-trials-search in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add wu-yc/LabClaw --skill clinical-trials-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/clinical-trials-search, .gemini/skills/clinical-trials-search, .github/skills/clinical-trials-search and .opencode/skills/clinical-trials-search in your project.
Going by SKILL.md and its folder, Clinical Trials Search needs the command-line tools its instructions call (jq). Our summary lists: Python 3; Node.js.
SKILL.md names 4 domains. In commands or code: api.valyu.ai and clinicaltrials.gov; the agent is likely to contact these 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.
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.
Clinical Trials Search is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.3k tokens (SKILL.md is roughly 5.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Clinical Trials Search: Clinical Trials Database (google-deepmind/science-skills, 3.2k stars), CHARLS Paper Reproduction Guide (xjtulyc/MedgeClaw, 617 stars), Biomedical Analysis Dispatch (xjtulyc/MedgeClaw, 617 stars) and Research Paper (luwill/research-skills, 862 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
