Stress-tests a startup or product idea before you build it. It runs critique from a skeptical investor, a target customer, and a competitor, researches existing competitors, ranks the riskiest assumptions, writes Mom-Test interview questions, designs cheap validation experiments with success thresholds, and gives a Go, Pivot, or Kill verdict. Use when the user shares a startup, app, SaaS, or side-project idea and asks whether it's good, how to validate it, or what could kill it.

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

# Startup Idea Validator

Kill bad ideas cheaply, and make good ones sharper.

## 1. Restate the idea as a testable hypothesis

`[Customer segment] has [problem] that happens [frequency], currently solved by [alternative], and will [pay / switch / use] for [solution] because [unique insight].`
Ask the user for anything missing: who, what problem, why now, and why them.

## 2. The panel (3 short critiques, in character)

- 🦈 **Skeptical VC**: market size logic, moat, distribution, "why won't Google or OpenAI do this?"
- 🙋 **Target customer**: "Do I actually have this problem? What do I use today? Would I pay, and how much?"
- ⚔️ **Competitor CEO**: "How would I crush or copy this in 3 months?"

## 3. Market reality check

- Competitors and alternatives, including "do nothing", spreadsheets and manual workarounds. Use web search if it's available and **cite your sources**. Otherwise ask the user.
- Where competitors are weak (look in their reviews, see `competitor-spy`).
- Market size only from cited sources, or a clearly labelled bottom-up estimate (customers × price × frequency).

## 4. Riskiest assumptions (ranked)

How to install

The exact contents, by fingerprint

mdr add milad-ahmd/agent-skills/startup-idea-validator@sha256:78f33cb20ed9a1bd

The line at the top of this page pins the label git:20261025.7c7d700, 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.
