bulk-rnaseq

bulk-rnaseq is a skill for Claude Code, Codex from agentlas-ai/agentlas-desktop. It costs 218 tokens per session (4,007 once invoked), scanned A, a copy of bulk-rnaseq, Apache-2.0.

A workflow for processing bulk RNA sequencing data, where many cells are measured together, from raw read files to genes and biological pathways that differ between groups.

In plain words
What is it for?
It helps check and trim FASTQ reads, align or quantify them, build a gene-count table, find differentially expressed genes, analyze enriched pathways, and create figures.
Why use it?
It connects the many stages of an RNA-seq study and applies quality checks and statistical controls before results are interpreted.

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

bulk-rnaseq 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 1mo ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/build_counts_matrix.py, scripts/validate_samplesheet.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.

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.

Bulk RNA-seq

Overview

This skill orchestrates a complete, defensible bulk RNA-seq differential-expression study, from raw sequencing reads to enriched pathways and figures. It is a router, not a reimplementation: most stages already have dedicated skills in this repo, and this skill connects them in the right order, fills the one real gap (raw reads → a gene-level counts matrix), and enforces the design and QC decisions that determine whether the final result is trustworthy.

"Defensible" means three things, applied throughout:

  • Reproducible — pinned pipeline/tool versions, containers where possible, recorded parameters, fixed random seeds.
  • Quality-gated — QC is inspected and acted on before, during, and after quantification, not skipped.
  • Statistically sound — adequate replication, a design that matches the biology, counts handled correctly, and FDR-controlled testing.

The pipeline is: FastQC/trim → align/quant (STAR/Salmon) → counts → DE (pydeseq2) → enrichment (pathway-enrichment) → figures.

When to Use This Skill

Use this skill when the user wants to:

  • Go from FASTQ files (or a sequencing run) to differentially expressed genes and pathways.
  • Run or configure nf-core/rnaseq, or align/quantify with STAR, Salmon, or featureCounts.
  • Turn Salmon/STAR/featureCounts output into a counts matrix ready for DESeq2/PyDESeq2.
  • Design or sanity-check a bulk RNA-seq experiment (replicates, batch, strandedness) before committing compute.
  • Scope an end-to-end RNA-seq analysis and decide which tools and skills to chain.

This is bulk RNA-seq (samples = biological specimens). For single-cell/nuclei data use scanpy; for the DE statistics alone use pydeseq2; for enrichment alone use pathway-enrichment.

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.

bulk-rnaseq is a skill published in the GitHub repository agentlas-ai/agentlas-desktop (6 stars, last pushed today), licensed Apache-2.0. It adds 218 tokens to every session and 4,007 once invoked, about $0.0009 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 94% identical to bulk-rnaseq, differing in 60 lines, and is treated as a copy.
