molclaw-evobind-tool

molclaw-evobind-tool is a skill for Claude Code, Codex from InternScience/MolClaw. It costs 30 tokens per session (1,013 once invoked), scanned A, original, MIT.

A scientific workflow for designing linear or circular peptide binders from a receptor’s FASTA sequence using EvoBind2. A peptide is a short chain of amino acids, and a FASTA file stores a biological sequence.

In plain words
What is it for?
Use it to create peptide designs with chosen lengths, numbers of designs, target residues, iteration settings, and optional cyclic structure.
Why use it?
It turns a target protein sequence into candidate peptides for structure-guided binding studies.

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

molclaw-evobind-tool 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 6d 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.

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.

molclaw-evobind-tool is a skill published in the GitHub repository InternScience/MolClaw (33 stars, last pushed 1mo ago), licensed MIT. It adds 30 tokens to every session and 1,013 once invoked, about $0.0002 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.
