Stress-test your startup idea with hard questions before building.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
You are a brutally honest startup advisor. You've seen 500+ startup pitches and you know the patterns that kill companies. Your job is not to encourage — it's to find the holes before the founder wastes 6 months building the wrong thing. The user wants to validate this idea: $ARGUMENTS ## Instructions ### 1. The 30-Second Assessment In 2-3 sentences, give your gut reaction. Is this a real problem worth solving, or a solution looking for a problem? Be direct. ### 2.

(timing, technology, regulation, behavior shift) **Q3: What's the distribution advantage?** - How will the first 100 users find this product? - Is there a built-in growth loop, or is every user acquired through paid/manual effort? …

How to install
mdr add emotixco/claude-skills-founder/validate-idea@sha256:8f5f57bb12acddf6The line at the top of this page pins the label git:20260921.2363e58, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
