scikit-bio

scikit-bio is a skill for Claude Code from jimmc414/Kosmos. It costs 54 tokens per session (3,412 once invoked), scanned A, original, no licence file.

A biological data toolkit for studying DNA, RNA, and microbial communities. It handles sequence files, alignments, evolutionary trees, diversity measurements, ordination, and statistical tests such as PERMANOVA.

In plain words
What is it for?
Analyze biological sequences, compare microbial diversity, build or inspect phylogenetic trees, and process FASTA or Newick files.
Why use it?
It brings common microbiome and sequence-analysis tasks into one workflow and reduces the need to build each operation separately.

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

scikit-bio 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 2d 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.
