gwas-database

gwas-database is a skill for Claude Code from jaechang-hits/SciAgent-Skills. It costs 59 tokens per session (7,135 once invoked), scanned A, original, no licence file.

A connection to the NHGRI-EBI GWAS Catalog, a database of published studies linking genetic variants to traits and diseases. It uses the catalog's REST API to query studies, variants, traits, genes, and summary statistics.

In plain words
What is it for?
Finding SNP–trait associations, selecting candidates for polygenic risk scores, studying pleiotropy, and fetching data for Manhattan plots.
Why use it?
It helps developers retrieve genetic-association data without manually searching the database or building API requests from scratch.

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

gwas-database scanned grade A with 1 finding 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 9d ago.

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.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

What ships with it

1 file 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.
