The Prompt Nobody Types
An MVP is Not a Product
An MVP is a survey. V1 is what you build once you have the answers.
The MVP's only job is to ask the market a question. Do you want this? Will you pay? Where do you get stuck? What do you actually need that I haven't thought of yet? V1 is the product that gets built once those answers come in. No answers, no V1. Just another MVP, Just guessing with extra steps.
For years, slow builds accidentally made founders good at collecting answers. Three months of development meant three months of logging, debugging, watching. Instrumentation crept in during debug cycles. You were emotionally invested by launch day — you had earned the right to be nervous.
The slow build was doing invisible work. It was teaching you to listen.
Fast Code, Missing Data
Now, with vibe coding, Friday night you have an idea. Sunday night you have a product. You deploy, share the link, maybe post it somewhere. That feeling is real — you actually built something, and it only took a weekend. The prompt was clean: "build me an MVP for X." Functional. Fast. Deployed.
But nobody typed the rest of the prompt.
No event tracking. No error logs. No funnel visibility. No record of who came, what they clicked, where they stopped, or why they left.
Beautiful survey form. No pen.
A week passes. Maybe a month. Either nothing happened — or everything happened. You're staring at silence either way.
Two Bad Choices
Now you have two choices, both bad.
You Repeat
The Infinite LoopSpin up MVP2 over the next weekend. Different UI, tweaked copy, new guess. But you're not iterating on data, you're iterating on instinct. You're not moving forward, you're just painting the same wall a different color.
You Give Up
The Premature ExitClose the tab, call it a failed idea, move on. Maybe it was. Or maybe 60 people visited, someone spent 8 minutes on the pricing page, three people tried to sign up and hit a broken form. You'll never know. You just buried a product that had answers in it.
Either way, you wasted the one thing vibe coding was supposed to give you more of — time.
Add the Pen
The fix is simple, one line added to your prompt:
"add full observability — user events, errors, funnel tracking, and return visit data."
That's the pen. Without it you don't have an MVP. You have a very fast guess.
Vibe coding gave you a superpower. You can ship in a weekend what used to take a quarter. But someone very wise once said —
with great power comes great responsibility.
Use that speed to build the survey. Then use it again to add the pen. The power was never the problem. Forgetting to collect the answers is.
