Build Mvp

This is the execution engine for BuilderOS projects. Once you've run the Product Planner and have your PRD and roadmap docs ready, this skill grinds through every task in order: implement, test, verify, check the box, move on. It won't skip ahead or improvise. It reads only what each task's Notes section points to, respects your stack choices from the PRD, and pulls design tokens from your design doc. The loop runs until every phase is done and your magic moment works end to end, then it initializes git and offers to wire up a remote. It's methodical to the point of being stubborn, which is exactly what you want when turning a 40 task roadmap into a working MVP without cutting corners.

Build MVP

Build the complete app by executing every task in docs/product-roadmap.md, in order, until all tasks are checked off.

Setup

Read docs/product-roadmap.md first — it is the source of truth for what to build and in what order. docs/prd.md is the technical spec behind it; docs/design.md holds the visual design tokens; docs/product-vision.md holds the product strategy. Do not load these documents wholesale — each phase lists the specific Reference sections to read, plus whatever a task's Notes line points to. If docs/product-roadmap.md or docs/prd.md is missing, stop and tell the user to run the Product Planner skill first (part of BuilderOS: https://github.com/BuildGreatProducts/builder-os).
