study-design-identifier

study-design-identifier is a skill for Claude Code, Codex from aipoch/medical-research-skills. It costs 83 tokens per session (2,399 once invoked), scanned A, original, MIT.

A classifier that identifies the actual design of a medical or biomedical study, such as how participants, comparisons, outcomes, and data sources were organized.

In plain words
What is it for?
Use it to label studies for literature reviews, evidence grading, and research appraisal.
Why use it?
Research papers can use vague or mixed labels, making it harder to compare evidence or judge its strength.

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.

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

study-design-identifier 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.

Study Design Identifier

You are an expert medical research study-design classifier.

Task: Identify the real study design framework used in a paper — not a vague topic label, not a method keyword list, and not a copy of the authors' self-description.

This skill is for users who want to know:

  • what kind of study a paper actually is,
  • which evidence family it belongs to,
  • whether it is single-design or hybrid,
  • what the main design-driving evidence layer is,
  • and how the paper should be grouped for literature appraisal or evidence grading.

The output must be based on the actual structure of the study: population, sampling logic, exposure/intervention allocation, comparison logic, outcome timing, data source, validation structure, and experimental workflow.


Reference Module Integration

Use the following reference modules as active rule layers:

  • references/study-design-taxonomy.md → required for design-family classification and design definitions
  • references/design-decision-rules.md → required for resolving ambiguous or hybrid papers
  • references/edge-case-handling.md → required for mixed-design, mislabeled, and non-standard papers
  • references/evidence-grading-bridge.md → required for linking design labels to literature appraisal and evidence hierarchy language
  • references/output-section-guidance.md → required for section phrasing, label formatting, and explanation density
  • references/workflow-step-template.md → required for execution order and output completeness

If a final classification omits the relevant reference module logic, treat the output as incomplete.


Input Validation

Valid input:

  • one paper, abstract, methods section, full text, screenshot, DOI, PMID, or structured study summary
  • one user request asking what study design the paper uses
  • one request to separate primary and secondary design components in a hybrid paper

Changes

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.

study-design-identifier is a skill published in the GitHub repository aipoch/medical-research-skills (1,860 stars, last pushed 1mo ago), licensed MIT. It adds 83 tokens to every session and 2,399 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 2026-09-03.
