tooluniverse-epigenomics

tooluniverse-epigenomics is a skill for Claude Code, Codex from AndyZhuang/Opentest. It costs 205 tokens per session (13,784 once invoked), scanned A, original, MIT.

A genomics analysis skill for studying epigenomics data—the chemical changes that affect how genes work without changing DNA. It covers methylation, ChIP-seq, ATAC-seq, and combined datasets.

In plain words
What is it for?
Use it to filter and compare methylation data, find age-related CpG sites, measure chromosome-level patterns, analyze ChIP-seq peaks and ATAC-seq accessibility, and connect results with gene expression or regulatory annotations.
Why use it?
It removes the need to build common data-processing and statistical analyses from scratch when working with epigenomics experiments.

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

tooluniverse-epigenomics 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 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.

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.

Genomics and Epigenomics Data Processing

Production-ready computational skill for processing and analyzing epigenomics data. Combines local Python computation (pandas, scipy, numpy, pysam, statsmodels) with ToolUniverse annotation tools for regulatory context. Designed to solve BixBench-style questions about methylation, ChIP-seq, ATAC-seq, and multi-omics integration.

When to Use This Skill

Triggers:

  • User provides methylation data (beta-value matrices, Illumina arrays) and asks about CpG sites
  • Questions about differential methylation analysis
  • Age-related CpG detection or epigenetic clock questions
  • Chromosome-level methylation density or statistics
  • ChIP-seq peak files (BED format) with analysis questions
  • ATAC-seq chromatin accessibility questions
  • Multi-omics integration (expression + methylation, expression + ChIP-seq)
  • Genome-wide epigenomic statistics
  • Questions mentioning "methylation", "CpG", "ChIP-seq", "ATAC-seq", "histone", "chromatin", "epigenetic"
  • Questions about missing data across clinical/genomic/epigenomic modalities
  • Regulatory element annotation for processed epigenomic data

Example Questions This Skill Solves:

  1. "How many patients have no missing data for vital status, gene expression, and methylation data?"
  2. "What is the ratio of filtered age-related CpG density between chromosomes?"
  3. "What is the genome-wide average chromosomal density of unique age-related CpGs per base pair?"
  4. "How many CpG sites show significant differential methylation (padj < 0.05)?"
  5. "What is the Pearson correlation between methylation and expression for gene X?"
  6. "How many ChIP-seq peaks overlap with promoter regions?"
  7. "What fraction of ATAC-seq peaks are in enhancer regions?"
  8. "Which chromosome has the highest density of hypermethylated CpGs?"
  9. "Filter CpG sites by variance > threshold and map to nearest genes"
  10. "What is the average beta value difference between tumor and normal for chromosome 17?"

NOT for (use other skills instead):

  • Gene regulation lookup without data files -> Use existing epigenomics annotation pattern
  • RNA-seq differential expression -> Use tooluniverse-rnaseq-deseq2
  • Variant calling/annotation from VCF -> Use tooluniverse-variant-analysis
  • Gene enrichment analysis -> Use tooluniverse-gene-enrichment
  • Protein structure analysis -> Use tooluniverse-protein-structure-retrieval

tooluniverse-epigenomics is a skill published in the GitHub repository AndyZhuang/Opentest (22 stars, last pushed 6mo ago), licensed MIT. It adds 205 tokens to every session and 13,784 once invoked, about $0.0010 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.
