I spent the last weeks building Guildhall: any GitHub repo becomes a living 3D world, and AI agents walk through it as heroes. I'm not a game developer. So I wrote down everything it took: 6 deep dives, real numbers, real mistakes. 🧵

What does 13 years of React look like? I built Guildhall: it turns any GitHub repo into a living 3D world. Folders become villages, the biggest package the capital, and its history grows the land, commit by commit. When AI agents work on it, you watch them. 🏝️

Cockpit 0.9 is out: the instruments @opencode doesn't ship with. Shells that keep running, subagents you can watch, PR review in the terminal, a statusline that shows the context filling — and now Trail. cockpit.codestz.dev

Cockpit 0.7 is out, with a new bay: Subagents. OpenCode shows a subagent as one line in the chat. Now each one sits in the sidebar with what it's doing right now, and a click opens its whole run beside the conversation.

OpenCode 2.0 is out from @opencode, with a built-in shell and a diff view. Good basics. Cockpit is what I built for past the basics: four open-source instruments that make long-running, agent-driven work something you can watch and steer.
