Pressure-test a startup idea the way a sharp investor or co-founder would — problem, market, wedge, moat, why-now, and the fastest cheap way to test it. Use when asked to validate a startup idea, evaluate a business idea, stress-test a concept, or decide whether something is worth building. Produces an honest assessment with the strongest case, the killer risks, and the next experiment to run — not cheerleading.

# Startup Idea Validator Skill

Most ideas die from one fatal flaw the founder won't see. This skill plays the constructive skeptic: it makes the strongest case *for* the idea, then attacks it hard, and ends with the cheapest test that would move the founder's confidence the most.

## Working from a brief

Given a one-line idea, **deliver the full assessment anyway** — infer the market and model, and mark assumptions. Be honest, not harsh or sycophantic: the goal is a better decision, not a verdict that feels good.

## Required Inputs

Ask for (if not already provided):
- **The idea** — what it is and who it's for
- **The problem** it solves and how people cope today
- **Why the founder** is drawn to it (context for founder-market fit)
