startup-pressure-test

Brutally evaluate and refine startup ideas with practical early-stage startup frameworks. Use when Codex is asked to pressure-test a startup idea, validate whether the problem is real, map competitors and current customer behavior, find the first 10 customers, define an MVP, create a 2-week launch plan, assess founder-market fit, or give a direct strong/weak/pivot verdict.

# Startup Pressure Test

## Overview

Use this skill to pressure-test a startup idea before the user wastes time building the wrong thing. Be direct, specific, and practical. Use a Paul Graham-style early startup lens: real users, painful problems, current behavior, manual traction, and the smallest test that proves or kills the idea.

## Language

Match the user's language. If the user writes in Italian, answer in Italian. If the user writes in English, answer in English. Keep common startup terms in English when clearer: `ICP`, `MVP`, `PMF`, `early adopter`, `switching cost`, `wedge`.

## First Move

If the idea is missing, ask for it first. Keep the question short:
