Query IUPHAR/BPS Guide to Pharmacology (GtoPdb) for receptor-ligand interactions, target/ligand metadata, families, and approved drugs.

  • Works in 6 steps: Use geneSymbol=/accession= for canonical… → Read sub-resources for everything beyond… → Filter interactions via… → …
  • Tasks that involve Drug discovery and cheminformatics
  • SKILL.md covers Overview, When to Use, Prerequisites and Quick Start, plus 9 more sections
  • Calls pip; reaches guidetopharmacology.org

What it does

Gtopdb Database is an agent skill from jaechang-hits/SciAgent-Skills. Query IUPHAR/BPS Guide to Pharmacology (GtoPdb) for receptor-ligand interactions, target/ligand metadata, families, and approved drugs. Affinities (pKi/pIC50/pKd), action (Agonist/Antagonist/etc.), species, structures (SMILES/InChI). No auth. Always resolve targets via geneSymbol/accession; most metadata lives in sub-resources (/databaseLinks, /structure, /synonyms).

Its SKILL.md is about 4.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Research & Science, covering Drug discovery and cheminformatics, Cryptography and Protein structure and design. It works with UniProt. The repository describes itself as: 197 bioinformatics & life science skills for Claude Code and AI agents — BixBench 92.0% accuracy. RNA-seq, single-cell, drug discovery, proteomics, and more. Powers OmicsHorizon.

When your agent uses it

  • Tasks that involve Drug discovery and cheminformatics
  • Tasks that involve Cryptography
  • Tasks that involve Protein structure and design

Example prompts

  • “/gtopdb-database”

Requirements

  • Python 3

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Use geneSymbol=/accession= for canonical lookups, never name= — fuzzy name= matches across all fields and silently returns the wrong target.
  2. Read sub-resources for everything beyond IDs. Base /targets/{id} and /ligands/{id} records lack gene symbols, UniProt, SMILES, ChEMBL…
  3. Filter interactions via /targets/{id}/interactions or /ligands/{id}/interactions — never /interactions?targetId=…, which silently ignores…
  4. Use type=Approved server alias to fetch approved drugs; approved=true query param is ignored.
  5. Always cast affinity numerically with errors="coerce" — it's a string that can be ranges, qualified, or missing.
  6. Family endpoint is /targets/families — not /families (which 404s).

What it can do on your machine

Read from SKILL.md and the folder at commit 82c862c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • pip

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • guidetopharmacology.org

    Also links to:

    • doi.org

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Gtopdb Database loads about 4.9k tokens when it runs. Until then it costs about 96 tokens; SKILL.md has 853 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~96
When it runs · the whole SKILL.md, loaded when a task matches
~4.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 853 words (~4,855 tokens).

“The IUPHAR/BPS Guide to Pharmacology (GtoPdb) catalogues drug targets, ligands, and quantitative interactions across receptor pharmacology. The web services REST API at https://www.guidetopharmacology.org/services/ returns JSON for targets, ligands, interactions, and family hierarchies. Base records are intentionally lean — gene symbols…”
