Build MVP from Spec

Creates structured specifications before writing code to clarify requirements, surface assumptions, and define success criteria, reducing rework and miscommunication.

Turn a design or spec document into a working MVP by planning thin vertical slices, scaffolding the first slice, then building iteratively with test-driven development and gated commits.

Drive development with tests by writing a failing test before implementing code, and reproduce bugs with tests before fixing them.

Enforces running verification commands and confirming output before claiming work is complete, fixed, or passing, to prevent false success claims.

Turns product strategy into a production-grade MVP or shipped full-stack application using Next.js, Supabase, and Vercel with disciplined scope and quality standards.
