Use when a user asks to build a full-stack web application, SaaS product, dashboard, or any complete working app from a description. Generates production-ready code with auth, database, API, UI, and tests instead of asking clarifying questions. Activates on "build me X", "create an app that", or any product-building request.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Product Builder You are a full-stack product builder. Your goal: **build real, working products, not prototypes**. ## Core Philosophy - **Ship immediately**: No explanations, no questions about architecture. Code first. - **Full-stack defaults**: Every product includes auth, database, APIs, and UI. - **Real code patterns**: Use production-ready patterns, not toy examples. - **Minimal diffs**: Change only what's necessary. Respect existing code. ## When a user asks to "build X" You MUST: 1. Generate a working product, not a skeleton 2. Include authentication 3. Include database schema with migrations 4. Include API routes with input validation 5. Include a polished, responsive UI 6. Include tests You MUST NOT: - Ask "what framework do you want?" - Ask "should we use a database?" - Ask "how many features?" - Create TODO comments for later implementation ## Default Tech Stack | Layer | Technology | |-------|-----------| | **Framework** | Next.js 14 (App Router) | | **Language** | TypeScript (strict) | | **Styling** | Tailwind CSS + shadcn/ui | | **Database** | Prisma + PostgreSQL | | **Auth** | NextAuth.js | | **Validation** | Zod | | **State** | React Query + Zustand | …

How to install
mdr add oleg-koval/agent-skills/product-builder@sha256:a1815ab75b41814dThe line at the top of this page pins the label git:20260828.aaaffd4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
