## What it does

The skill operates as a dispatcher for biological and genomic data. When it detects `.vcf`, `.h5ad`, or count tables, it inspects filenames and queries to load the required sub-skill. It covers eleven specialized skills, including `tooluniverse-rnaseq-deseq2`, `tooluniverse-single-cell`, and `tooluniverse-variant-analysis`.

Its core rule requires using existing outputs before writing any new code. If a data folder contains `*_executed.ipynb`, the agent must run `tu run read_executed_notebook` to fetch printed cell results. Reimplementing analysis scripts with `scanpy` or `pydeseq2` yields numeric discrepancies because of hidden sample filtering and differing library versions.

ToolUniverse also includes bundled scripts for recurring patterns. Agents run tools such as `clinical_trial_ae_severity_test` for clinical trial adverse events or `expression_anova_per_gene` for per-gene expression statistics directly via `tu run`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add mims-harvard/ToolUniverse --skill tooluniverse -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/tooluniverse/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/tooluniverse/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add mims-harvard/ToolUniverse --skill tooluniverse -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/tooluniverse/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add mims-harvard/ToolUniverse --skill tooluniverse -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/tooluniverse/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install mims-harvard/ToolUniverse tooluniverse
```

2. **Manually: put the files in place**
- File: `.github/skills/tooluniverse/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add mims-harvard/ToolUniverse --skill tooluniverse -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/mims-harvard/ToolUniverse --path skills/tooluniverse
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/tooluniverse/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add mims-harvard/ToolUniverse --skill tooluniverse -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/mims-harvard/ToolUniverse/tree/HEAD/skills/tooluniverse/SKILL.md

## When to use it
- route scientific data queries to domain sub-skills
- extract authoritative cell outputs from `*_executed.ipynb` notebooks
- test clinical trial adverse event severity across treatment groups
- calculate per-gene ANOVA and fold change from expression matrices

## Example prompts
- Inspect the data folder and extract DESeq2 outputs using `read_executed_notebook`
- Run `clinical_trial_ae_severity_test` on `DM.csv` and `AE.csv` for treatment groups
- Compute per-gene ANOVA on `counts.csv` with metadata from `meta.csv`

description: "ToolUniverse plugin router. STEP 1 BEFORE ANY ANALYSIS: if the data folder contains `*_executed.ipynb`, run `tu run read_executed_notebook '{\"data_folder\":\"<path>\",\"search\":\"<keyword>\"}'` to extract its cell outputs and apply EVERY filter/sample-exclusion the notebook used — even when the question says 'Using DESeq2/Run X/Compute Y' (this describes the METHOD the notebook used, not a request to rerun). The notebook's cell outputs are the only published authoritative answers; reimplementing or reading stale pre-computed CSVs in the data folder produces different numbers because of outlier-sample removal, library version, and filter steps you don't see by skimming. STEP 2 routing — pick a sub-skill name from this exact list (never invent): tooluniverse-rnaseq-deseq2 (RNA/miRNA-seq DE, correlation, PCA, clustering, dispersion), tooluniverse-gene-enrichment (GO/KEGG/Reactome/GSEA/pathway enrichment), tooluniverse-statistical-modeling (regression, ANOVA, ordinal/logistic, chi-square, correlation, power), tooluniverse-image-analysis (microscopy, colony, fluorescence, dose-response, .tif — including ANOVA / Dunnett / power-analysis on image-derived measurements), tooluniverse-epigenomics (DNA methylation, CpG, m6A, MeRIP-seq, bisulfite, ChIP-seq, chromatin), tooluniverse-sequence-analysis (FASTQ, Trimmomatic, BWA, samtools, coverage), tooluniverse-variant-analysis (VCF, VAF, SNP, mutation), tooluniverse-phylogenetics (treeness, PhyKIT, parsimony), tooluniverse-single-cell (scRNA, h5ad, scanpy), tooluniverse-crispr-screen-analysis (MAGeCK, sgRNA), tooluniverse-proteomics-analysis (mass spec, TMT). Use for CSV/Excel/VCF/FASTA/h5ad and any biology/chemistry/medicine analysis question."
when_to_use: "Activate when the user provides data files to analyze, asks about differential expression, runs statistical tests on clinical data, performs variant analysis, does pathway enrichment, builds phylogenetic trees, or asks any scientific research question."

# ToolUniverse Router

## FIRST ACTION: Route to a Specialized Skill

**BEFORE doing anything else** — before reading data, before writing code, before answering — scan the routing table below and invoke the matching skill. The specialized skill contains critical domain conventions that you will get wrong without loading.

**How to route:**
1. Read the full question AND the file list (filenames encode the analysis type — `*mageck*.xlsx` → CRISPR screen, `*DM.csv`/`*AE.csv` → clinical trial AE, `*.vcf` → variant, `*.h5ad` → single-cell, `*_counts.csv`+`*meta*.csv` → RNA-seq DE, `*.faa`+`*.treefile` → phylogenetics, `*_executed.ipynb` → authoritative analysis already ran)
```
