geo-database SKILL.md skillA
geo-database from marielynneblock/arcanum-artifex is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add marielynneblock/arcanum-artifex/geo-database@git:20260710.0115f49Pins git:20260710.0115f49 in mdr.lock. Pin the fingerprint instead.

Access NCBI GEO for gene expression/genomics data. Search/download microarray and RNA-seq datasets (GSE, GSM, GPL), retrieve SOFT/Matrix files, for transcriptomics and expression analysis.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# GEO Database ## Overview The Gene Expression Omnibus (GEO) is NCBI's public repository for high-throughput gene expression and functional genomics data. GEO contains over 264,000 studies with more than 8 million samples from both array-based and sequence-based experiments. ## When to Use This Skill This skill should be used when searching for gene expression datasets, retrieving experimental data, downloading raw and processed files, querying expression profiles, or integrating GEO data into computational analysis workflows. ## Core Capabilities ### 1. Understanding GEO Data Organization GEO organises data hierarchically using different accession types: **Series (GSE):** A complete experiment with a set of related samples - Example: GSE123456 - Contains experimental design, samples, and overall study information - Largest organisational unit in GEO - Current count: 264,928+ series **Sample (GSM):** A single experimental sample or biological replicate - Example: GSM987654 - Contains individual sample data, protocols, and metadata - Linked to platforms and series - Current count: 8,068,632+ samples **Platform (GPL):** The microarray or sequencing platform used …

How to install
mdr add marielynneblock/arcanum-artifex/geo-database@sha256:d057a730a70e9ee8The line at the top of this page pins the label git:20260710.0115f49, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
