100 / 100 · Low risk

Fine to try.

By emotixco/claude-skills-founder (GitHub) · coding · 844 stars · scanned at commit ea6864c

Stress-test a startup idea before any code is written. Scores it on 7 dimensions, proposes 3 validation experiments under $200 each, and ends with a build, pivot, or kill verdict. Use when a founder asks whether an idea is worth building.

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/'validate-idea' ] || [ -L ~/.agents/skills/'validate-idea' ]; then echo 'A skill folder named validate-idea already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/emotixco/claude-skills-founder' "$d" && git -C "$d" checkout --quiet 'ea6864c05c2f4a3666b9d6c14c550b20f35a04c9' -- 'skills/validate-idea' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/validate-idea' ~/.agents/skills/'validate-idea' && 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/'validate-idea' ~/.claude/skills/'validate-idea' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
