pubchem-compound-search
77 / 100 · Review before installing
Check before installing. Some of what it can do is expected: a coding skill usually runs build and test commands.
By jaechang-hits/SciAgent-Skills (GitHub) · coding · 388 stars · scanned at commit 65d6ceb
Query PubChem (110M+ compounds) directly via the PUG-REST/JSON API with plain `requests` — no SDK install required. Search by name/CID/SMILES/InChIKey/formula, retrieve properties (MW, XLogP, TPSA, H-bond counts), do similarity/substructure searches with async ListKey polling, fetch synonyms, descriptions, assay summaries, and download SDF/PNG. For local cheminformatics use rdkit; for bioactivity-centric workflows use chembl-database-bioactivity.
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/'pubchem-compound-search' ] || [ -L ~/.agents/skills/'pubchem-compound-search' ]; then echo 'A skill folder named pubchem-compound-search 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 "$d" checkout --quiet '65d6ceb875e20b751ffb3a6d8ee19516558789e1' -- 'skills/structural-biology-drug-discovery/pubchem-compound-search' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/structural-biology-drug-discovery/pubchem-compound-search' ~/.agents/skills/'pubchem-compound-search' && 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/'pubchem-compound-search' ~/.claude/skills/'pubchem-compound-search' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
