iggm

iggm is a skill for Claude Code, Codex from BioTender-max/ProteinClaw. It costs 127 tokens per session (1,095 once invoked), scanned A, original, no licence file.

A tool for designing antibody and nanobody CDR loops. CDRs are the parts of an antibody that usually make contact with its target; a nanobody is a smaller antibody-like protein.

In plain words
What is it for?
Designing nanobody loops, full antibody heavy- and light-chain CDRs, existing antibody CDRs, and target-conditioned antibody candidates.
Why use it?
It helps create or revise target-specific binding regions without designing the whole antibody from scratch.

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

iggm 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 7d 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.

iggm is a skill published in the GitHub repository BioTender-max/ProteinClaw (11 stars, last pushed 6mo ago), with no licence file. It adds 127 tokens to every session and 1,095 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.
