100 / 100 · Low risk

Fine to try.

By Uxcel-Lab/product-skills (GitHub) · design · 40 stars · scanned at commit 5007cd0

Plan how to test the assumptions behind a product idea before building — decompose the idea into its load-bearing beliefs, prioritize the riskiest, phrase them as falsifiable hypotheses, and pick the cheapest method that answers the question. Or critique an existing validation plan. Trigger when asked to validate an idea, de-risk a feature, plan discovery/experiments, test assumptions or a hypothesis, design an MVP test, or decide "how do we know this will work?"

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/'pm-assumption-testing' ] || [ -L ~/.agents/skills/'pm-assumption-testing' ]; then echo 'A skill folder named pm-assumption-testing already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/Uxcel-Lab/product-skills' "$d" && git -C "$d" checkout --quiet '5007cd0241ccaa51ae2e4681f9618912dc10e239' -- 'pm/processes/assumption-testing' && mkdir -p ~/.agents/skills && cp -R "$d"/'pm/processes/assumption-testing' ~/.agents/skills/'pm-assumption-testing' && 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/'pm-assumption-testing' ~/.claude/skills/'pm-assumption-testing' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
