neondatabase/appdotbuild-agent ? reverse-engineered prompt

Build me an AI app builder that can take a single plain English request and turn it into a working app with the basic setup already done for me.

I want it to be able to scaffold real projects, include tests and linting, and prepare whatever deployment bits are needed so the app is actually usable, not just a demo. It should handle data focused apps too, like dashboards, analytics tools, and other business style interfaces. If you need to look up current docs or best practices online, go ahead.

Make it so I can run it as a standalone tool, and also connect it to another agent through MCP so I can say something like, create an app that shows sales by region, and get a full project back. Please keep the workflow simple and practical, with sensible defaults, clear prompts, and generated code that is ready to iterate on.
