protein-qc

protein-qc is a skill for Claude Code, Codex from BioTender-max/ProteinClaw. It costs 126 tokens per session (1,085 once invoked), scanned A, original, no licence file.

Quality-control guidance for checking protein-design results against structural, binding, expression, and sequence criteria. It includes measures such as pLDDT, ipTM, and PAE, which indicate confidence in predicted structures and interfaces.

In plain words
What is it for?
Use it to set filtering thresholds, assess binding and structure quality, check expression-related risks, and detect issues such as excess cysteines, deamidation sites, or polybasic clusters.
Why use it?
It helps filter out designs that look unreliable, difficult to produce, or likely to have problematic sequence features before further testing.

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

protein-qc scanned grade A with 0 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 10d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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.

protein-qc is a skill published in the GitHub repository BioTender-max/ProteinClaw (11 stars, last pushed 6mo ago), with no licence file. It adds 126 tokens to every session and 1,085 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
