Thanks, I think what I needed is in `packaging`.

Do you know what is the alternative, beyond pinning setuptools<81?

Here's one pointer: a notebook shared model has a shared text for an input cell.
github.com/jupyter-serv...
That allows multiple users to type into the cell at the same time. It's a CRDT so conflicts are resolved automatically in real-time. That's how collaboration works in Jupyter. AI could use it.

No, I think most Jupyter AI extensions' workflow is rather to treat the AI as a collaborator and use the real-time collaboration system to modify the shared model of the notebook, not the underlying JSON directly.

Jupyter has integrated AI in the notebook's environment. I think @willmcgugan.bsky.social's Toad is doing the other way around: integrating the notebook in the AI environment.

I've added a tree view to pick files in Toad. ๐ธ
Fuzzy searching is great when you know what you're looking for. But a tree view is more natural when you want to look through your files.
Toad is a unified interface for agentic coding, and all things AI, in your terminal.

FPS is a framework for running asynchronous applications.
Thanks to its borrow checker, async resources can be shared safely. They are torn down when all borrowers have dropped their reference, making sure no "dangling" resource is used.
This is very much inspired by Rust.

Put some final touches to Toad's permission request screen.
When the agent has an update, it pops this screen up. You can review the diffs in unified or split view, then decide if you want to accept or reject the changes.
