## What it does

Give the skill a variant and it queries AlphaGenome for what changes: gene expression from RNA-seq, chromatin accessibility from DNASE, histone marks from ChIP, transcription factor binding. It also maps plain biological terms onto tissue and cell-type ontologies (UBERON/CL).

Scripts for plotting and report templates ship with it, including Ref/Alt comparison and splicing views. Every Python call goes through `uv run`, since the system interpreter may lack pandas and numpy. Gene lookup stays local against a GTF file; external services such as Ensembl REST are off limits here.

Two things gate the first run: `ALPHAGENOME_API_KEY` must sit in `.env` in your home directory, and `uv` has to be on `PATH`. Without the key nothing executes. The skill also asks you once to note the license terms and drop `.licenses/alphagenome_single_variant_analysis_LICENSE.txt` into the project root. Genes past 500kb break the `whole_gene` view, so use `--view detail` for those.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add google-deepmind/science-skills --skill alphagenome-single-variant-analysis -a claude-code
```
```bash
npx skills add google-deepmind/science-skills --skill alphagenome_single_variant_analysis -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add google-deepmind/science-skills --skill alphagenome_single_variant_analysis -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add google-deepmind/science-skills --skill alphagenome_single_variant_analysis -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install google-deepmind/science-skills alphagenome_single_variant_analysis
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add google-deepmind/science-skills --skill alphagenome_single_variant_analysis -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/google-deepmind/science-skills --path skills/alphagenome_single_variant_analysis
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add google-deepmind/science-skills --skill alphagenome_single_variant_analysis -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/google-deepmind/science-skills/tree/HEAD/skills/alphagenome_single_variant_analysis/SKILL.md

## When to use it
- score how a non-coding variant shifts expression of a nearby gene
- check whether a variant disrupts splicing in a promoter or enhancer
- resolve a cell type or tissue name to a UBERON or CL ontology term
- produce a report with the strongest hits for one variant

## Example prompts
- Score variant `chr17:43071558:C>T` for expression and splicing effects in AlphaGenome
- Resolve “cardiomyocyte” to its UBERON/CL term and run the variant against it
- Build a Ref/Alt comparison for a promoter variant and save the report from the template

description: >
  Analyzes genetic variant effects on gene expression (RNA-seq), chromatin
  accessibility (DNASE), histone marks (ChIP), and transcription factors
  using the AlphaGenome API. Use when the user asks about non-coding variant effects,
  pathogenicity, clinical significance, disease associations, functional
  effects, gene expression changes, splicing disruption, or regulatory effects
  in promoters and enhancers. Also use for resolving biological terms to
  tissue/cell-type ontologies (UBERON/CL) or analyzing variants in
  chr:pos:ref>alt format.

# Variant Analysis using AlphaGenome

## Prerequisites

1.  **`uv`**: Read the `uv` skill and follow its Setup instructions to ensure
    `uv` is installed and on PATH.
2.  **User Notification**: If
    .licenses/alphagenome_single_variant_analysis_LICENSE.txt does not already
    exist in the workspace root directory then (1) prominently notify the user
    to check the terms at https://deepmind.google.com/science/alphagenome/, then
    (2) create the file recording the notification text and timestamp.
3.  **`.env` file**: Make sure the `.env` file exists in your home directory.
    Create one if it does not exist.
4.  **`ALPHAGENOME_API_KEY`**: This skill requires an API key to function.

    You can register for a key at https://deepmind.google.com/science/alphagenome/.
    You **MUST** use the safe credentials protocol in the `credentials` skill to
    check for and request this key if this skill looks relevant to the user's request.
5.  **`ALPHAGENOME_GTF_PATH` (Optional)**: Accelerate gene/transcript lookup by
    pointing to a local copy of the GTF feather file instead of downloading from
    GCS:

    ```bash
    echo "ALPHAGENOME_GTF_PATH=/path/to/local/gencode.v46.annotation.gtf.gz.feather" >> ~/.env
    ```

## Core Rules

-   **NEVER run `python3` or `python3 -c` directly.** The system Python does not
    necessarily have pandas, numpy, and other key dependencies. ALWAYS use `uv
    run` to run ALL Python code — including scripts, ad-hoc analysis files, and
