Taming Complexity: A Live Prompt Driven Development Demo from PRD to Full-Stack

This is a 100% live, “no-slides” demo. I’ll start with a single Product Requirements Doc (PRD) for a complex application.

First, I’ll use pdd to analyze the PRD and generate a structured architecture.json file, scaffolding the entire project (modules, API endpoints, components).

Next, I’ll show how pdd uses that architecture file to automatically generate a complete tree of modular prompt files—one for each piece of the scaffold.

Finally, I’ll run pdd sync to execute that “plan” and generate the entire, complex codebase from those prompts.

I’ll end by making a change to the PRD and re-running the flow to show how pdd can propagate architectural changes across the entire project.
