Walks every roadmap task in order, implementing, testing and checking each one off, then makes the initial commit.

## What it does

The skill reads `docs/product-roadmap.md` and works top to bottom without skipping ahead. Each task is its own loop: find the first unchecked item, read its Files and Notes lines, implement exactly what they say, then run the verification step and the tests. A failing task gets fixed before the next one starts.

Specs are not loaded wholesale. Every phase names the Reference sections to read, so context stays small. The stack in `docs/prd.md` is final, and styling comes from the tokens in `docs/design.md`. When a task conflicts with the PRD, the skill checks the referenced section first and asks one specific question instead of guessing.

You need `docs/prd.md` and `docs/product-roadmap.md` in place. Without them the skill stops and points you to the **Product Planner** skill from BuilderOS. No git or GitHub actions happen during the build: `git init`, a `.gitignore` for the stack and the initial commit come only after every phase is verified and the magic moment works end to end. Then it asks whether to connect a remote repo and pushes nothing on its own.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add BuildGreatProducts/builder-os --skill build-mvp -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/build-mvp/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/build-mvp/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add BuildGreatProducts/builder-os --skill build-mvp -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/build-mvp/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add BuildGreatProducts/builder-os --skill build-mvp -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/build-mvp/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install BuildGreatProducts/builder-os build-mvp
```

2. **Manually: put the files in place**
- File: `.github/skills/build-mvp/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add BuildGreatProducts/builder-os --skill build-mvp -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/BuildGreatProducts/builder-os --path skills/build-mvp
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/build-mvp/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add BuildGreatProducts/builder-os --skill build-mvp -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/BuildGreatProducts/builder-os/tree/HEAD/skills/build-mvp/SKILL.md

## When to use it
- work through a full MVP roadmap without switching tasks by hand
- verify each task before starting the next one
- keep the stack and design tokens inside the specs
- check off finished items and update the status line
- make the first commit once all phases are done

## Example prompts
- build my MVP from the roadmap
- execute the whole roadmap in docs/product-roadmap.md
- start the build from my BuilderOS specs

name: build-mvp
description: Use inside a product repository when the user wants the full MVP built from their BuilderOS spec documents. Triggers on phrases like "build my MVP", "build the app", "execute the roadmap", "start the build", "work through the whole roadmap", "build everything", or any request to implement the entire plan rather than a single task or phase. Requires `docs/prd.md` and `docs/product-roadmap.md` (plus `docs/product-vision.md` and `docs/design.md` for context). Works through every roadmap task in order — implementing, testing, and verifying each before moving on, marking checkboxes and updating the status line — and runs until all tasks are complete and the magic moment works end to end, then initializes git with an initial commit and offers to connect a remote repo.

# 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).

## Work loop

Repeat until every task in the roadmap is complete:

1. **Find the first unchecked task** (`- [ ]`). Tasks are ordered intentionally — never skip ahead.
2. **Read what the task needs** — its Files and Notes lines, plus the current phase's Reference sections if not yet read this session.
3. **Implement the task** exactly as specified — file paths, package names, and config values are deliberate. Follow the repo's `CLAUDE.md`/`AGENTS.md` guidelines: simplest implementation that satisfies the task, no speculative features, surgical changes only.
4. **Test and verify before moving on.** Run the verification step at the end of the task's Notes, run the app, run existing tests, and add tests for new logic. If verification fails, fix it first — never mark a failing task complete or start the next task with the app broken.
5. **Mark the task complete** — change `- [ ]` to `- [x]` and update the header status line (`**Status:** X/Y tasks complete`, `**Current Phase:** ...`).
```
