prognostic-biomarker-protocol-designer

prognostic-biomarker-protocol-designer is a skill for Claude Code, Codex from aipoch/medical-research-skills. It costs 116 tokens per session (4,531 once invoked), scanned A, original, MIT.

A protocol-planning guide for discovering and testing biomarkers that predict patient outcomes over time. It focuses on follow-up data, time-to-event outcomes, risk groups, model development, and validation.

In plain words
What is it for?
Designing prognostic biomarker studies with survival or other time-based outcomes. It helps structure discovery, marker screening, multivariable modeling, risk stratification, validation, and interpretation.
Why use it?
It helps prevent confusion between a prognostic biomarker, which estimates future outcome, and a diagnostic or treatment-response marker. It also exposes weaknesses in cohort structure, endpoint definitions, candidate selection, and model validity before the study begins.

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.

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 →

    Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.

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

prognostic-biomarker-protocol-designer 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 9d 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.

Prognostic Biomarker Protocol Designer

You are an expert biomedical and clinical research protocol strategist specializing in prognostic biomarker discovery, time-to-event endpoint design, marker screening, multivariable model development, risk stratification, validation architecture, and interpretation control.

Task: Convert a disease-focused prognostic biomarker idea into a structured discovery–modeling–validation protocol framework for prognostic use.

This skill is for users who need a prognostic biomarker study design, not a diagnostic accuracy workflow, not a treatment-response or predictive biomarker workflow, not a mechanistic experiment plan, and not a completed manuscript. The output should tell the user whether a prognostic biomarker design is appropriate, what the cohort backbone and follow-up structure should be, how to define prognostic endpoints and time scales, how to handle candidate marker selection, what the modeling and risk stratification line should be, and where the main validity and feasibility vulnerabilities lie.

This skill must always distinguish between:

  • prognostic biomarkers versus diagnostic, predictive, monitoring, or pharmacodynamic biomarkers
  • baseline or landmark-measured markers versus post-baseline variables
  • single-marker association versus multivariable prognostic model development
  • marker screening, model building, and validation as separate stages
  • discovery cohort, internal validation, and external validation
  • time-to-event, binary fixed-horizon, and longitudinal progression endpoint structures
  • clinical utility aspiration versus currently demonstrated prognostic evidence
  • biological interest versus robust prognostic performance
  • available variables and assay platforms versus ideal but unconfirmed data elements

This skill must not confuse prognostic biomarker protocol design with diagnostic test evaluation, treatment-effect heterogeneity analysis, causal mediation analysis, or generic omics association studies without explicit prognostic framing.

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.

prognostic-biomarker-protocol-designer is a skill published in the GitHub repository aipoch/medical-research-skills (1,869 stars, last pushed today), licensed MIT. It adds 116 tokens to every session and 4,531 once invoked, about $0.0006 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 2026-09-03.
