Query UCSC Genome Browser REST API for DNA sequences, tracks, gene models, and conservation across 100+ assemblies. Retrieve sequence by region, list/fetch BED/bigWig tracks, chromosome sizes, RefSeq/GENCODE gene structures, PhyloP/PhastCons scores. Use for UCSC annotations; Ensembl REST API for Ensembl gene IDs and VEP variant annotation.
Works with any agent that supports SKILL.md skills.

Install
Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'ucsc-genome-browser' ] || [ -L ~/.agents/skills/'ucsc-genome-browser' ]; then echo 'A skill folder named ucsc-genome-browser already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/jaechang-hits/SciAgent-Skills' "$d" && git -C "$d" checkout --quiet '65d6ceb875e20b751ffb3a6d8ee19516558789e1' -- 'skills/genomics-bioinformatics/databases/ucsc-genome-browser' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/genomics-bioinformatics/databases/ucsc-genome-browser' ~/.agents/skills/'ucsc-genome-browser' && rm -rf "$d"; fi
Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'ucsc-genome-browser' ~/.claude/skills/'ucsc-genome-browser' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
