lifesciences-research: Skill for Claude Code

.claude/skills/lifesciences-genomics/SKILL.md

lifesciences-genomics is a skill for Claude Code from donbr/lifesciences-research. It costs 101 tokens per session (1,573 once invoked), scanned A, original, MIT.

A command-line toolkit for querying gene and genome databases such as Ensembl, NCBI, and HGNC, which catalog genes and their biological information.

In plain words
What is it for?
Use it to look up genes, retrieve gene metadata, annotate variants, find orthologs—corresponding genes in other species—map identifiers, search NCBI Gene, and link genes to PubMed articles.
Why use it?
It avoids manual searches across different genomics databases and helps resolve different identifiers for the same gene. It also supports checking variants and relationships between genes in different species.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is donbr/lifesciences-research's own configuration. It tells Claude Code how to work on lifesciences-research itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything lifesciences-research configures →

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

lifesciences-genomics scanned grade A with 1 finding 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 12d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.
