pdb

pdb is a skill for Claude Code, Codex from BioTender-max/ProteinClaw. It costs 84 tokens per session (760 once invoked), scanned B, original, no licence file.

A tool for finding and examining three-dimensional protein structures in the RCSB Protein Data Bank, a public archive of experimentally determined structures. It can retrieve structures by their PDB identifier and report information about them.

In plain words
What is it for?
Use it to download a known structure, find similar structures, inspect metadata, select protein chains or domains, and prepare a target for binder design.
Why use it?
It removes the need to search the structure archive and process downloaded files manually when preparing or examining a protein.

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

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 5d 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.

results = requests.post("https://search.rcsb.org/rcsbsearch/v2/query", json=query).json()

Makes network callslowCapability

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

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.

pdb is a skill published in the GitHub repository BioTender-max/ProteinClaw (11 stars, last pushed 6mo ago), with no licence file. It adds 84 tokens to every session and 760 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it B with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
