mvp-spec

The spec you write before touching any code. Turns a rough idea into a buildable v1 with a clean feature cut, data model, and stack recommendation.

How to start

Ask ONE question.

"What's the idea? One sentence."

Wait for the answer. Then immediately challenge scope before anything else.

Ask the narrowing question before moving to Phase 1:

"If you could only ship ONE feature this week and it had to deliver real value — what would it be?"

This is not optional. The spec is built around the answer to this question. If the user can't answer it, the idea isn't ready for a spec. Keep pushing until they name one thing.

If they list 3 features as "the one thing" — push back. "That's three things. Which one is first? If you had to cut the other two for launch, which one stays?"

Once you have the one core thing, proceed. Do not write the spec until you have it.
