What this actually is
Munder Difflin is a desktop app, not a prompt pack. You install it, it opens a small 2D office, and every character sitting at a desk on that floor is a real command-line agent running on your own machine. You brief one of them, and it hands parts of the work to the others while you watch it happen.
That distinction matters more than it sounds. Almost every "AI agent team" you have seen is a folder of markdown role definitions you copy into a prompt. This is a running program with state: each agent has its own working directory, its own memory that survives the app being closed, and its own mailbox that other agents post into.
- Repository: github.com/chaitanyagiri/munder-difflin
- 6,161 stars on GitHub at the time this was written
- Source code is MIT licensed. The pixel-art tileset is licensed separately from LimeZu and needs credit, so the app is free to use but the art is not yours to lift
- Runs on macOS, Windows and Linux. Marked pre-release at v0.4.6
- It uses the CLI subscription you already have rather than metered API keys
One thing to be clear about before you install anything. This is early software with a busy issue tracker, and an office of agents left running unsupervised will happily produce an office of nonsense. Everything below is written on the assumption that you will point it at a real repository, give it a real briefing, and leave the permission gate switched on. That gate is the feature, not the friction.
