Maps the assumptions behind an innovation initiative (desirability, feasibility, viability), picks the riskiest one, and writes an experiment card with pass and fail thresholds set before the experiment runs, part of the Innovation Pack by 90n. Use this whenever the user says "run experiment-designer", "design an experiment", "how do we test this without building it", "what is our riskiest assumption", "write the experiment card", or when a team is about to build something and has not said what…

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

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

if [ -e ~/.agents/skills/'experiment-designer' ] || [ -L ~/.agents/skills/'experiment-designer' ]; then echo 'A skill folder named experiment-designer already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/polar-bear-org/claude-skills' "$d" && git -C "$d" checkout --quiet '95f01806ca43f6ee788d0579743e35853b695930' -- 'packs/innovation-pack/skills/experiment-designer' && mkdir -p ~/.agents/skills && cp -R "$d"/'packs/innovation-pack/skills/experiment-designer' ~/.agents/skills/'experiment-designer' && 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/'experiment-designer' ~/.claude/skills/'experiment-designer' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
