foldseek

foldseek is a skill for Claude Code, Codex from BioTender-max/awesome-bio-agent-skills. It costs 90 tokens per session (1,350 once invoked), scanned A, original, no licence file.

A tool for finding proteins with similar three-dimensional shapes using Foldseek. It can search databases such as the Protein Data Bank and AlphaFold Database.

In plain words
What is it for?
Use it to search for structural relatives, find remote homologs, query protein-structure databases, and group similar structures.
Why use it?
Proteins with related shapes may be related even when their amino-acid sequences look different. Shape-based searching can reveal matches that sequence searches miss.

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 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 11d 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.

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.

foldseek is a skill published in the GitHub repository BioTender-max/awesome-bio-agent-skills (176 stars, last pushed 2mo ago), with no licence file. It adds 90 tokens to every session and 1,350 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 2 findings (makes network calls, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
