What it does

Clinicaltrials DB is an agent skill from aipoch/medical-research-skills. Query the ClinicalTrials.gov API v2 to search for clinical trials, retrieve detailed study protocols, and analyze recruitment status; use when you need to find trials by condition/drug, export results, or verify study details by NCT ID.

Its SKILL.md is about 760 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts and reference files (for example `clinicaltrials-db_audit_result_v1.json`, `references/api_reference.md` and `scripts/query_clinicaltrials.py`).

It sits in Business, Finance & HR, covering Recruiting and HR and Clinical and healthcare research. The repository describes itself as: Hundreds of agent skills for medical research, including protocol design, data analysis, evidence insights, and academic writing. The licence is MIT.

When your agent uses it

You need to find trials by condition/drug
Verify study details by NCT ID

Example prompts

“/clinicaltrials-db”

Requirements

Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit 686e09d. 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
Ships 1 file in scripts/ (Python), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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

Clinicaltrials DB loads about 762 tokens when it runs, and up to ~964 if it reads all its reference files. Until then it costs about 64 tokens; SKILL.md has 228 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~64
When it runs · the whole SKILL.md, loaded when a task matches: ~762
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~964

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); the scripts in this folder are not scanned.

name: clinicaltrials-db
description: Query the ClinicalTrials.gov API v2 to search for clinical trials, retrieve detailed study protocols, and analyze recruitment status; use when you need to find trials by condition/drug, export results, or verify study details by NCT ID.
license: MIT
author: AIPOCH

Source: https://github.com/aipoch/medical-research-skills

When to Use

You need to find clinical trials for a specific condition (e.g., “cancer”) and filter by recruitment status (e.g., Recruiting).
You want to locate trials involving a particular intervention (drug/biologic/device) and quickly review matching studies.
You need to retrieve full study protocol details (including eligibility criteria) for a known NCT identifier.
You want to export or programmatically process trial metadata for downstream analysis or reporting.
You need to validate study status and key fields (phase, locations, sponsor) from the authoritative ClinicalTrials.gov source.

Key Features

Search studies via ClinicalTrials.gov API v2 using common filters (condition, intervention, recruitment status, result limits).
Retrieve detailed study information by NCT ID, including protocol and eligibility criteria.
Simple Python interface for integrating trial search and retrieval into scripts and pipelines.
Reference documentation for advanced query parameters and field definitions (see references/api_reference.md).

Dependencies

Python 3.9+
requests >= 2.28

Example Usage

python

from scripts.query_clinicaltrials import search_studies, get_study_details

def main():
    # 1) Search studies (example: recruiting cancer studies)
    results = search_studies(
        condition="cancer",
        status="RECRUITING",
        limit=10,
    )

    print("Search results:")
    for i, item in enumerate(results, start=1):
        # The exact keys depend on the API fields returned by the implementation.
        # Print the raw item to keep this example runnable across field selections.
        print(f"\n[{i}] {item}")

    # 2) Get study details by NCT ID
    nct_id = "NCT01234567"
    study = get_study_details(nct_id)

    print(f"\n\nStudy details for {nct_id}:")
    print(study)

if __name__ == "__main__":
    main()

Implementation Details

API Backend: Uses ClinicalTrials.gov API v2 endpoints to query study records and fetch study details.
Search Parameters:
- condition: Condition/disease term used to match relevant studies.
- status: Recruitment status filter (e.g., RECRUITING).
- limit: Maximum number of records to return.
Study Detail Retrieval:
- get_study_details(nct_id) fetches the full record for a single study identified by its NCT ID and returns the protocol-level information (including eligibility criteria when available).
Advanced Queries / Field Definitions:
- For additional query parameters, response fields, and definitions, refer to references/api_reference.md.

Files

Or copy the skill folder (scientific-skills/Evidence Insight/clinicaltrials-db in aipoch/medical-research-skills) into .agents/skills/clinicaltrials-db in your project. Codex loads it when a task matches its description.

Can I use Clinicaltrials DB 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 aipoch/medical-research-skills --skill clinicaltrials-db -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/clinicaltrials-db, .gemini/skills/clinicaltrials-db, .github/skills/clinicaltrials-db and .opencode/skills/clinicaltrials-db in your project.

What does Clinicaltrials DB need to run?

Going by SKILL.md and its folder, Clinicaltrials DB needs Python for the scripts in its folder. Our summary lists: Python 3.

Does Clinicaltrials DB access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Clinicaltrials DB 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. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does Clinicaltrials DB use?

Clinicaltrials DB 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 Clinicaltrials DB use?

About 762 tokens (SKILL.md is roughly 3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 202 tokens, read only when the agent opens those files.

What are the alternatives to Clinicaltrials DB?

Skills that share tags, products or a category with Clinicaltrials DB: Searching Clinicaltrials (maziyarpanahi/openmed, 5.5k stars), Ct Status Diff (agentii-ai/agentii-investment-intelligence, 207 stars), Clinical Trials Database (google-deepmind/science-skills, 3.2k stars) and Pp Clinical Trials (mvanhorn/printing-press-library, 2.1k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Clinicaltrials DB?

aipoch (a GitHub organization) maintains it in aipoch/medical-research-skills, which has 1,937 GitHub stars. The repository holds 578 skills in this directory. The repository was last updated on September 17, 2026.
