tooluniverse-rnaseq-deseq2

tooluniverse-rnaseq-deseq2 is a skill for Claude Code, Codex from AndyZhuang/Opentest. It costs 124 tokens per session (4,476 once invoked), scanned A, original, MIT.

A workflow for finding genes whose activity differs between groups in RNA sequencing data. It uses DESeq2-style statistical analysis to normalize read counts, account for variability, test contrasts, and connect selected genes with biological pathways.

In plain words
What is it for?
Use it with RNA-seq count data and sample information to compare conditions, analyze multiple factors or contrasts, shrink fold-change estimates, filter results by chosen thresholds, and perform gene annotation or pathway enrichment.
Why use it?
Raw read counts cannot be compared directly because samples differ in sequencing depth and biological variability. This workflow applies the statistical steps needed to identify meaningful changes while supporting multi-factor designs and batch effects.

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-rnaseq-deseq2 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 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.

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.

RNA-seq Differential Expression Analysis (DESeq2)

Comprehensive differential expression analysis of RNA-seq count data using PyDESeq2, with integrated enrichment analysis (gseapy) and gene annotation via ToolUniverse.

BixBench Coverage: Validated on 53 BixBench questions across 15 computational biology projects covering RNA-seq, miRNA-seq, and differential expression analysis tasks.


Core Principles

  1. Data-first approach - Load and validate count data and metadata BEFORE any analysis
  2. Statistical rigor - Always use proper normalization, dispersion estimation, and multiple testing correction
  3. Flexible design - Support single-factor, multi-factor, and interaction designs
  4. Threshold awareness - Apply user-specified thresholds exactly (padj, log2FC, baseMean)
  5. Reproducible - Set random seeds, document all parameters, output complete results
  6. Question-driven - Parse what the user is actually asking and extract the specific answer
  7. Enrichment integration - Chain DESeq2 results into pathway/GO enrichment when requested
  8. English-first queries - Use English gene/pathway names in all tool calls

When to Use This Skill

Apply when users:

  • Have RNA-seq count matrices and want differential expression analysis
  • Ask about DESeq2, DEGs, differential expression, padj, log2FC
  • Need dispersion estimates or diagnostics
  • Want enrichment analysis (GO, KEGG, Reactome) on DEGs
  • Ask about specific gene expression changes between conditions
  • Need to compare multiple strains/conditions/treatments
  • Ask about batch effect correction in RNA-seq
  • Questions mention "count data", "count matrix", "RNA-seq", "transcriptomics"

Required Packages

# Core (MUST be installed)
import pandas as pd
import numpy as np
from pydeseq2.dds import DeseqDataSet
from pydeseq2.ds import DeseqStats

# Enrichment (optional, for GO/KEGG/Reactome)
import gseapy as gp

# ToolUniverse (optional, for gene annotation)
from tooluniverse import ToolUniverse

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.
