garrytan/gstack ? reverse-engineered prompt

I want to build a system that turns my coding assistant into a complete, virtual engineering team. I was inspired by Garry Tan's "gstack" project, and I want that kind of setup. The whole idea is to have a bunch of specialized agents that I can call on for different tasks throughout the software development process.

For example, I should be able to start by talking to a "CEO" agent to brainstorm and refine a feature. Then, other agents should step in for design, architecture planning, and the actual coding. I definitely want a QA agent that can open a real browser and test a staging URL for bugs. Finally, there should be a release manager agent to handle the pull request and deployment. It should all be controlled with simple slash commands, like /plan-ceo-review, /qa, and /ship. The goal is to have an entire software factory in my editor so I can build faster.
