query-pdb

query-pdb is a skill for Claude Code, Codex from BioTender-max/awesome-bio-agent-skills. It costs 70 tokens per session (972 once invoked), scanned B, original, no licence file.

A database lookup for experimentally determined protein structures. The RCSB Protein Data Bank stores structures produced with methods such as X-ray crystallography, cryo-electron microscopy, and NMR.

In plain words
What is it for?
Looking up PDB identifiers and finding crystal, cryo-EM, or NMR structures of proteins.
Why use it?
It provides a direct way to find three-dimensional evidence about a protein rather than relying only on sequence or predicted structure.

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 B, and why

query-pdb scanned grade B with 2 findings 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 12d 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.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

What this file has done since we first saw it

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.
