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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00067 | $0.02804 |
| Opus 5 | $0.00034 | $0.01402 |
| Sonnet 5 | $0.00013 | $0.00561 |
| Haiku 4.5 | $0.00007 | $0.00280 |
Grade A, and why
nomogram-construction 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 — 339 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Nomogram Construction
When to Use
Use this skill when you need to:
- build a prognosis nomogram from already selected clinical prognostic variables;
- estimate model discrimination with a C-index table;
- export a nomogram bundle and generate a publication-ready nomogram PDF.
Typical user requests:
- "Build a prognosis nomogram from age, stage, and risk score."
- "Use these Cox-selected predictors to construct a nomogram and calculate the C-index."
- "Generate a nomogram PDF from a survival prediction model."
When Not to Use
Do not use this skill for:
- screening prognostic variables from scratch with Cox regression;
- ROC curves, calibration curves, or decision-curve analysis;
- diagnosis models, binary classification, or non-survival outcomes;
- single-cell, differential-expression, or pathway analysis.
When to Read External Files
| Situation | File to Read | Purpose |
|---|---|---|
| Need algorithm details | references/algorithm.md |
Cox-based nomogram workflow, C-index, and assumptions |
| Need to run analysis | scripts/main.R |
Execute Rscript scripts/main.R --mode build ... or --mode plot ... |
| Encounter errors | references/troubleshooting.md |
Common SKILL_* errors and solutions |
| Need CLI examples | references/cli-guide.md |
Detailed command-line examples |
| Need test data | tests/data/ |
Example clinical CSV for smoke testing |
Input Validation
This skill accepts:
- A clinical CSV file with survival time, event indicator, and pre-selected prognostic features
- Requests to build a Cox-based prognostic nomogram and compute the C-index
- Requests to re-render a nomogram PDF from an existing
.qsbundle (plot mode)
If the user's request does not involve nomogram construction from survival data — for example, asking to screen features with Cox regression, generate calibration curves, perform ROC analysis, or analyze non-survival binary outcomes — do not proceed with this workflow. Instead respond:

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.

nomogram-construction is a skill published in the GitHub repository aipoch/medical-research-skills (1,855 stars, last pushed 1mo ago), licensed MIT. It adds 67 tokens to every session and 2,804 once invoked, about $0.0003 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.
