I built a 9-agent AI dev team in a Claude Code plugin — here's what happened

The moment I realized AI coding assistants were broken I was building a side project - a simple task manager app. I opened Claude Code, typed: "Add user authentication with email and password login" …and hit enter. Twenty minutes later, I had code. Authentication logic, routes, middleware, even some basic tests. But there was a problem. The frontend (me, on a different day) had assumed a different API shape. The tests only covered the happy path. There was no architecture decision to reference - I just picked JWT because it felt right. And the docker-compose.yml? It didn't exist yet.
