bio-geo-data

bio-geo-data is a skill for Claude Code, Codex from PKU-YuanGroup/OpenAI4S. It costs 141 tokens per session (4,776 once invoked), scanned A, a copy of bio-geo-data, MIT.

A data-access tool for GEO and related repositories, which store gene-expression experiments and their sample and platform details. It can find studies and download processed tables or the original supporting files.

In plain words
What is it for?
Use it to find expression datasets, inspect study and sample metadata, download series matrices, and retrieve raw or supplementary files for further analysis.
Why use it?
It helps distinguish submitter-processed data from raw data and avoids mixing samples incorrectly when a study contains several sub-studies or measurement platforms.

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

bio-geo-data 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 8d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/geo_from_pubmed.py, scripts/geo_to_sra.py, scripts/search_geo.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.

How it starts

The opening of the file, as written. The whole thing — 381 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Version Compatibility

Reference examples tested with: BioPython 1.83+, GEOparse 2.0+, R Bioconductor GEOquery 2.70+, pandas 2.2+

Before using code patterns, verify installed versions match. If versions differ:

  • Python: pip show biopython geoparse then introspect signatures
  • R: packageVersion('GEOquery')

If the GSE structure doesn't match expectations (missing fields, malformed series matrix), re-fetch from FTP directly and inspect the SOFT or MINiML file as source of truth.

GEO Data

"Pull expression data from GEO accession GSE..." -> GEO stores Series (GSE), Samples (GSM), Platforms (GPL), and curated DataSets (GDS, frozen 2018). The single most consequential decision is processed (series matrix) vs raw (supplementary files / linked SRA) — the answer turns on how much trust the submitter's normalization deserves.

The single most-missed gotcha: SuperSeries. A GSE may be a meta-container (!Series_relation = SuperSeries of: GSExxxxx) holding multiple sub-studies on different platforms. Naively pulling samples from a SuperSeries gives mixed Affymetrix + Illumina + RNA-seq, mis-batched.

  • Python: Entrez.esearch(db='gds'), GEOparse for full series download
  • R: GEOquery::getGEO() (Bioconductor; more mature than GEOparse)
  • CLI: wget from ftp.ncbi.nlm.nih.gov/geo/series/...

Required Setup

pip install biopython GEOparse pandas
# OR for R-side:
# R: BiocManager::install('GEOquery')
from Bio import Entrez
Entrez.email = '[email protected]'
Entrez.api_key = 'optional'

GEO record taxonomy

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.

bio-geo-data is a skill published in the GitHub repository PKU-YuanGroup/OpenAI4S (407 stars, last pushed yesterday), licensed MIT. It adds 141 tokens to every session and 4,776 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 98% identical to bio-geo-data, differing in 12 lines, and is treated as a copy.
