I'm using T3 Code as well. I like that it's completely open source and Theo is beyond transparent about how it works, imo. And he clearly uses it himself.

Then I used Claude to build an app called "Superintendent" that controls T3 Code through its API in a way that maximizes what I get out of my subscriptions.

One thing it does is, if I've got extra capacity building up for some reason (i.e. getting to the end of the week without using my limit), it will take a look at the projects I've pointed it to and ask Opus 5.5. to look at the projects and suggest improvements. Then, if there's capacity, it will build them on a separate worktree and be there for me to review or decline.

I've got some other features like a dashboard that shows the limits and logs its activities and a way to ask it to "refine" random ideas I give it, then I can Approve/Deny them and they'll get queued to get built with whatever capacity I have left over. It pauses gracefully when I use T3 code actively, too.
