pyopenms

pyopenms is a skill for Claude Code, Codex from jimmc414/Kosmos. It costs 86 tokens per session (1,341 once invoked), scanned A, original, no licence file.

A Python interface to OpenMS for analysing mass spectrometry data, which measures chemical or molecular signals. It supports workflows for proteomics, the study of proteins, and metabolomics, the study of small molecules.

In plain words
What is it for?
It helps process LC-MS/MS data, detect features, identify peptides, and quantify proteins or metabolites using formats such as mzML and mzIdentML.
Why use it?
It brings file handling, signal processing, identification, and measurement tasks into Python-based analysis pipelines.

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

pyopenms 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 yesterday.

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 ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
