pdb-structure

pdb-structure is a skill for Claude Code, Codex from beita6969/ScienceClaw. It costs 80 tokens per session (1,291 once invoked), scanned A, original, MIT.

A programming guide for searching the RCSB Protein Data Bank, a public repository of experimentally determined 3D structures of proteins and other biological molecules.

In plain words
What is it for?
It helps find structures by text, retrieve metadata, inspect experimental details, and download structure files for research workflows.
Why use it?
It provides a way to retrieve structural biology data without manually searching and downloading entries from the database.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

pdb-structure scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

pdb-structure is a skill published in the GitHub repository beita6969/ScienceClaw (898 stars, last pushed 3mo ago), licensed MIT. It adds 80 tokens to every session and 1,291 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
