clinvar-database

clinvar-database is a skill for Claude Code, Codex from google-deepmind/science-skills. It costs 45 tokens per session (4,015 once invoked), scanned A, original, Apache-2.0.

A database of human genetic variants and the evidence behind their clinical classifications, such as Pathogenic, Benign, or Variant of Uncertain Significance (VUS). It is maintained by the National Center for Biotechnology Information (NCBI).

In plain words
What is it for?
Use it to look up clinical significance and pathogenicity for human genomic variants, review supporting evidence, and find confirmed positive variants for testing or benchmarking variant-analysis tools.
Why use it?
It provides a common reference for judging whether a DNA change may be related to disease, including the reasoning and evidence submitted by clinical and research groups.

About the project

Science Skills is a collection of add-ons that give AI agents structured instructions, scripts, and references for scientific research, including genomics, structural biology, cheminformatics, and literature search. Researchers use it to guide agents through specialized scientific tasks with information from databases and tools such as AlphaGenome, AFDB, and UniProt. The catalogue entries are individual skills from this collection.

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 A, and why

clinvar-database scanned grade A with 0 findings 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 6d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/clinvar_api.py), 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

ClinVar Database

Prerequisites

  1. uv: Read the uv skill and follow its Setup instructions to ensure uv is installed and on PATH.
  2. User Notification: If .licenses/clinvar_database_LICENSE.txt does not already exist in the workspace root directory then (1) prominently notify the user to check the terms at https://www.ncbi.nlm.nih.gov/clinvar/, then (2) create the file recording the notification text and timestamp.
  3. .env file: Make sure the .env file exists in your home directory. Create one if it does not exist.
  4. NCBI_API_KEY (optional): Raises the NCBI rate limit from 3 to 10 requests/second. The skill works without it, but a key is recommended if the user plans many queries or encounters a 429 error. You can register for a key for free at https://www.ncbi.nlm.nih.gov/account/settings/. You MUST use the safe credentials protocol in the credentials skill to check for and request this key if this skill looks relevant to the user's request.

Overview

ClinVar is the primary consensus record for clinical classifications of human genomic variations. It provides the "clinical ground truth" for pathogenicity labels (Pathogenic, Likely Pathogenic, Benign, VUS) based on assertions from global laboratories.

When to Use

Use when you need to:

  • Find the current clinical significance and star rating (review status) for a specific variant.
  • Fetch clinician notes, assertion criteria, or rationales for previous clinical laboratory classifications.
  • Retrieve the preferred condition name and associated HPO terms for a specific variant.
  • Find a list of variant controls (e.g., "Find all Pathogenic variants in the HBB gene within 50bp of a signal").
  • Check for conflicting interpretations for a given variant and identify the organizations submitting each classification.

Do NOT use when you need to:

  • Find specific allele frequencies in global populations (use gnomAD).
  • Describe the normal biological role of a protein and typical inheritance patterns (use OMIM).
  • Predict mechanistic effects of novel mutations, like frameshifts or exon skipping (use AlphaGenome).
  • Find recommended surveillance schedules for patients with a pathogenic variant (use GeneReviews).
  • Generate or view 3D structural models of affected proteins (use PDB / AlphaFold).

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

clinvar-database is a skill published in the GitHub repository google-deepmind/science-skills (2,844 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 45 tokens to every session and 4,015 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
