foldseek

foldseek is a skill for Claude Code, Codex from BioTender-max/ProteinClaw. It costs 90 tokens per session (736 once invoked), scanned A, original, no licence file.

A search tool for comparing protein three-dimensional structures. It can search structure databases such as the Protein Data Bank and AlphaFold Database.

In plain words
What is it for?
Finding similar structures, searching for structural homology, querying databases with a 3D structure, finding remote homologs, and clustering structures.
Why use it?
It can find related proteins that sequence-only searches miss, including distant structural relatives.

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

foldseek 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 8d 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.

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.

foldseek is a skill published in the GitHub repository BioTender-max/ProteinClaw (11 stars, last pushed 6mo ago), with no licence file. It adds 90 tokens to every session and 736 once invoked, about $0.0005 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 2026-08-30.
