gnomad-database

gnomad-database is a skill for Claude Code from Delphine-L/claude_global. It costs 62 tokens per session (1,924 once invoked), scanned A, original, no licence file.

A guide for querying gnomAD, the Genome Aggregation Database, which contains genetic variation data from large human populations. It covers population allele frequencies, gene constraint scores such as pLI and LOEUF, and loss-of-function intolerance through a GraphQL API.

In plain words
What is it for?
Use it for rare-disease variant interpretation, pathogenicity assessment, population-frequency checks, and finding genes that are intolerant of loss-of-function changes.
Why use it?
It helps interpret whether genetic variants or genes are uncommon or appear less able to tolerate damaging changes.

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

gnomad-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 11d 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.

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.

gnomad-database is a skill published in the GitHub repository Delphine-L/claude_global (19 stars, last pushed 3mo ago), with no licence file. It adds 62 tokens to every session and 1,924 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
