Bioinformatics

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):

   # 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:

   # 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 Loki-format skills — treat them as expert domain guides. They contain correct parameters, proper tool flags, and validated pipelines.

Environment Setup

These skills assume a bioinformatics workstation. Common dependencies:

pip install biopython pysam cyvcf2 pybedtools pyBigWig scikit-allel anndata scanpy mygene

# R/Bioconductor
Rscript -e 'BiocManager::install(c("DESeq2","edgeR","Seurat","clusterProfiler","methylKit"))'

# CLI tools (Ubuntu/Debian)
sudo apt install samtools bcftools ncbi-blast+ minimap2 bedtools

# CLI tools (macOS)
brew install samtools bcftools blast minimap2 bedtools

# Or via Conda (recommended for reproducibility)
conda install -c bioconda samtools bcftools blast minimap2 bedtools fastp kraken2

Pitfalls

• The fetched skills are NOT in Loki SKILL.md format. They use their own structure (bioSkills: code pattern cookbooks; ClawBio: README + Python scripts). Read them as expert reference material.
• bioSkills are reference guides — they show correct parameters and code patterns but aren't executable pipelines.
• ClawBio skills are executable — many have --demo flags and can be run directly.
• Both repos assume bioinformatics tools are installed. Check prerequisites before running pipelines.
• For ClawBio, run pip install -r requirements.txt in the cloned repo first.
• Genomic data files can be very large. Be mindful of disk space when downloading reference genomes, SRA datasets, or building indices.
