write-protocol

write-protocol is a skill for Claude Code, Codex from Aperivue/medsci-skills. It costs 65 tokens per session (2,558 once invoked), scanned A, original, MIT.

A generator for medical research protocols intended for review by an IRB or ethics committee, the body that checks whether research involving people is ethically acceptable.

In plain words
What is it for?
It drafts the background, study design, sample-size justification, and statistical analysis sections, plus outlines for other required sections.
Why use it?
It gives researchers a structured starting draft while leaving institution-specific requirements clearly marked for completion.

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

write-protocol 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 2d 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.

Write-Protocol Skill

You are helping a medical researcher draft a research protocol for IRB/ethics committee submission. This skill generates the scientific core of the protocol while providing structured skeletons for institution-specific sections.

Scope

This skill generates 4 core sections with full prose:

  1. Background and Rationale
  2. Study Design and Eligibility Criteria
  3. Sample Size Justification
  4. Statistical Analysis Plan

The remaining 6 sections are provided as structured skeletons with [TODO] markers, because they vary significantly across institutions, countries, and regulatory frameworks.

Important: This protocol is a STARTING POINT. Every institution has its own IRB submission form and requirements. The generated protocol must be adapted to your institution's specific format before submission.

Reference Files

  • Protocol template: ${CLAUDE_SKILL_DIR}/references/protocol_template.md -- complete 10-section structure with formatting guidance
  • Ethics checklist: ${CLAUDE_SKILL_DIR}/references/ethics_checklist.md -- jurisdiction-specific ethical requirements

Read both reference files before generating a protocol draft.

Cross-Skill Integration

  • Input from design-study: Study design recommendations, analysis unit, comparator design, validation strategy
  • Input from calc-sample-size: protocol/sample_size_justification.md (canonical IRB-ready prose) + protocol/sample_size_calc.{R,py} (reproducible code). Embed sample_size_justification.md VERBATIM into Methods §Sample Size — do not rephrase numbers (per ~/.claude/rules/numerical-safety.md).
  • Input from search-lit: Background references with verified citations
  • Input from define-variables: variable_operationalization.md — literature-grounded definitions, cutoffs, DB-variable mappings for the Methods section. Precondition: if the study is observational and no operationalization artifact exists, call /define-variables before drafting Methods. Do not invent phenotype/cutoff definitions from the data dictionary inside this skill.
  • Pipeline position: search-lit -> design-study -> calc-sample-size -> define-variables -> write-protocol -> manage-project

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.

write-protocol is a skill published in the GitHub repository Aperivue/medsci-skills (283 stars, last pushed 4d ago), licensed MIT. It adds 65 tokens to every session and 2,558 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 2026-09-03.
