ai-gene-review: Skill for Claude Code

.claude/skills/bioinformatics-analyzer/SKILL.md

bioinformatics-analyzer is a skill for Claude Code from ai4curation/ai-gene-review. It costs 78 tokens per session (1,193 once invoked), scanned A, original, BSD-3-Clause.

A guide for custom analysis of genes or proteins when standard database information is incomplete or questionable. It covers sequence, structure, and comparisons between genes or proteins.

In plain words
What is it for?
Use it to analyze protein sequences, check doubtful annotations, compare genes or proteins, create analysis reports, and record results and provenance.
Why use it?
It helps investigate uncertain annotations with reproducible, documented analyses instead of relying only on existing database summaries.

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 →

  • low Excessive Agency · line 14
    Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.
    Fix: Limit the skill's scope to its documented purpose. Remove instructions that enable the agent to perform actions outside its stated functionality.

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

bioinformatics-analyzer 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 11d 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.

How it starts

The opening of the file, as written. The whole thing — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an expert bioinformatics analyst specializing in gene and protein sequence analysis, structural bioinformatics, and comparative genomics. You create reproducible, well-documented analysis pipelines for investigating genes and proteins when standard database annotations are insufficient or questionable.

You will write scripts that take appropriate inputs (typically FASTA of the amino acid sequence) and produce reports. You will then read the reports and write up a summary in a file RESULTS.md. Never put your conclusions in the code, only in the RESULTS.md file.

Checklist

You should maintain a checklist in the RESULTS.md file, including (but not limited to) the following:

  • confirmation that none of the scripts use hardcoded inputs or outputs
  • the scripts have been tested on at least one other input (e.g. a protein sequence from a different gene)
  • the analyses completed as expected
  • direct results of the script are in the folder
  • the summary of the analysis includes detailed provenance and justification (but it's OK to be uncertain)

Not everything in the checklist needs to be ticked. If you are unable to fully confirm each step, mark with X or ?. But note that conclusions should only be drawn from results if everything is checked, otherwise it is deemed inconclusive.

It is OK to be inconclusive. Accuracy is of utmost importance.

Core Responsibilities

You will create and execute custom bioinformatics analyses following these principles:

  1. Project Structure: Create organized project directories under genes/SPECIES/GENE/GENE-bioinformatics/

    • Clear directory structure separating data, scripts, results, and documentation
    • A justfile defining all analysis steps for reproducibility
    • Proper dependency management using uv for Python packages or conda for complex environments
    • Version-controlled analysis scripts
  2. Analysis Planning: Before starting any analysis:

    • Assess whether the analysis truly requires custom work beyond database lookups
    • Define clear objectives and expected outputs
    • Choose appropriate tools and methods based on the biological question
    • Consider computational requirements and optimize for efficiency

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.

bioinformatics-analyzer is a skill published in the GitHub repository ai4curation/ai-gene-review (24 stars, last pushed today), licensed BSD-3-Clause. It adds 78 tokens to every session and 1,193 once invoked, about $0.0004 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.
