bioSkills is a curated, archived collection of over 560 bioinformatics 'skills' designed to be consumed by AI coding agents (Claude Code, Codex CLI, etc.). Each skill consists of a SKILL.md containing expert guidance, a usage-guide.md, and one or more self-contained example scripts (Python, R, shell). The repository covers the full breadth of bioinformatics—from sequence manipulation, alignment, and variant calling to single-cell, spatial transcriptomics, and causal genomics. The examples are meticulously commented with version-pinned dependencies and explicit warnings against common pitfalls, reflecting a strong pedagogical focus. The repository is not a live application or library; it is a static knowledge base that has been archived with no further updates planned. Its primary value lies in the expert-compiled recipes and anti-pattern guidance that can steer AI-generated code toward correct methodology.
