What this skill does

# Bioinformatics Skills Gateway

Use when asked about bioinformatics, genomics, sequencing, variant calling, gene expression, single-cell analysis, protein structure, pharmacogenomics, metagenomics, phylogenetics, or any computational biology task.

This skill is a gateway to two open-source bioinformatics skill libraries. Instead of bundling hundreds of domain-specific skills, it indexes them and fetches what you need on demand.

## Sources

◆ **bioSkills** — 385 reference skills (code patterns, parameter guides, decision trees)
  Repo: https://github.com/GPTomics/bioSkills
  Format: SKILL.md per topic with code examples. Python/R/CLI.

◆ **ClawBio** — 33 runnable pipeline skills (executable scripts, reproducibility bundles)
  Repo: https://github.com/ClawBio/ClawBio
  Format: Python scripts with demos. Each analysis exports report.md + commands.sh + environment.yml.

## How to fetch and use a skill

1. Identify the domain and skill name from the index below.
2. Clone the relevant repo (shallow clone to save time):
   ```bash
   # bioSkills (reference material)
   git clone --depth 1 https://github.com/GPTomics/bioSkills.git /tmp/bioSkills

   # ClawBio (runnable pipelines)
   git clone --depth 1 https://github.com/ClawBio/ClawBio.git /tmp/ClawBio
   ```
3. Read the specific skill:
   ```bash
   # bioSkills — each skill is at: <category>/<skill-name>/SKILL.md
   cat /tmp/bioSkills/variant-calling/gatk-variant-calling/SKILL.md

   # ClawBio — each skill is at: skills/<skill-name>/
   cat /tmp/ClawBio/skills/pharmgx-reporter/README.md
   ```
4. Follow the fetched skill as reference material. These are NOT Hermes-format skills — treat them as expert domain guides. They contain correct parameters, proper tool flags, and validated pipelines.
