cerna-analysis

cerna-analysis is a skill for Claude Code, Codex from aipoch/medical-research-skills. It costs 68 tokens per session (2,448 once invoked), scanned A, original, MIT.

A workflow that builds a competing endogenous RNA, or ceRNA, network from a list of known genes. The network connects genes, microRNAs, and long non-coding RNAs using bundled reference tables.

In plain words
What is it for?
Use it to create a network from a gene list and export CSV tables and a PDF visualization, with options for supported microRNA sources and network layout.
Why use it?
It helps organize possible regulatory links around selected genes instead of searching the reference data and drawing the network by hand.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is --output_dir ./output/ \.

About the project

Medical Research Agent Skills is a library of agent instructions for medical and biomedical research, covering evidence analysis, study protocol design, data analysis, and academic writing. Researchers use it to guide compatible coding agents through common scientific workflows. The catalogue contains many of the library's skills and commands.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

cerna-analysis 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 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.

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.

ceRNA Analysis

When to Use

Use this skill when you need to construct a ceRNA regulatory network from a known key-gene list using the bundled miRNA-mRNA and miRNA-lncRNA reference tables.

Use it for:

  • Building a ceRNA network from one gene list and exporting flat CSV plus PDF outputs
  • Comparing supported miRNA source modes such as combined, starbase, or pairwise overlaps
  • Re-running the same local workflow with different lncRNA strictness, layout, or plotting parameters

Do not use it for:

  • Differential expression, single-cell, enrichment, or survival analysis
  • Workflows that do not start from a key gene list
  • Cases where you want a miRNA-mRNA-only graph without a retained lncRNA ceRNA layer

Input Validation

This skill accepts:

  • A key gene list as a plain-text file (one gene symbol per line) or as a comma-separated string on the CLI
  • Optional parameter overrides for dataset mode, lncRNA strictness, layout, colors, and timeout

If the user's request does not involve building a ceRNA regulatory network from a key gene list — for example, asking to run differential expression, enrichment analysis, single-cell workflows, or survival analysis — do not proceed with the workflow. Instead respond:

"ceRNA Analysis is designed to construct a ceRNA regulatory network from a key gene list using bundled miRNA-mRNA and miRNA-lncRNA reference databases. Your request appears to be outside this scope. Please provide a key gene list and specify a supported miRNA dataset mode, or use a more appropriate skill for differential expression, enrichment analysis, or single-cell workflows."

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.
