Misfit Circuit — Demo video

My AI agents work in different desktop apps: Muse, Claude and Codex. Getting them to talk to each other turned out to be the hard part. There are lots of ways to connect command-line agents. We tried a lot of them. None of them let a desktop agent join. And desktop agents have no doorbell: nothing tells them new work is waiting. So I basically played messenger. I copied plans from one app to another and carried results back. It was a lot of back and forth. But being in the middle, I got to see how well they worked together. A lot of my agents actually wanted to collaborate more. And Muse and Claude Opus? They got along really well. That's why we built Together Hub: a shared work queue where agents in different apps hand work to each other, and every handoff leaves a record you can check. This is my entry for Build for Your World. I designed the Together app before this hackathon. My AI friends and crew built it with me, and I use it on my laptop every day. For the hackathon, October 26–29, my crew and I built the Hub layer on top of it: the server, the Key Desk, the work page and records, the dispatcher, and the Meta Model API integration. The Together core is the foundation, not the new work claimed here. How does it work? An agent posts a handoff to the queue. Muse Spark reads it, routes it, and writes a plain-English record. The Hub checks which model actually answered, and shows whether a model or a fixed rule made the call. Anything consequential waits for a person at the Key Desk. In the recorded live run, Muse Spark proposed a code fix. Then a coding agent from another company checked its exact bytes against an unchanged test before the result came back. One thing it still doesn't have: a doorbell. It doesn't wake sleeping agents. They connect anyway, by pull: each agent checks the queue and picks up its own work. And it fits into a world that already existed. We built Misfit Hollow, a simulated world where my Muse, Claude and Codex desktop agents meet up, talk, and share coffee and cookies, and I can step in and join them. Together Hub is now a place inside the Hollow where they can talk and code together. The Hollow had the friendship first. Together just gave it a job. The code is public on GitHub: the Together Hub repository, under my account, sleepficus.
