Use when planning how many patients or cases a study needs before data collection (power analysis, IRB justification). Walks a decision tree to the right test and returns reproducible R/Python code and IRB-ready justification text. Analyzing collected data is /analyze-stats.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'calc-sample-size' ] || [ -L ~/.agents/skills/'calc-sample-size' ]; then echo 'A skill folder named calc-sample-size already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/Aperivue/medsci-skills' "$d" && git -C "$d" checkout --quiet 'e0ea3b0be3bf529aa0b94ee5fd8450e78848932c' -- 'skills/calc-sample-size' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/calc-sample-size' ~/.agents/skills/'calc-sample-size' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'calc-sample-size' ~/.claude/skills/'calc-sample-size' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
