What's Wrong?

/ultraplan Please check whether an Electron app or a tiny Swift app is better. The initial screen is a
terrible idea, it should be mimicking the expereince of the original ms-dos app entirely, not try to make
something new. The TurboPascal code on launch, would show a screen that told you the number of waiting
roosevelts. All of the commands could be there. The text 'editor' could be exactly the same, but it could
accept a command-v paste if someone wanted to dump in a bunch of pre-written text. And probably tighten the
requirements for the agent coding the API, examples and what is needed for the client to operate well.

The Claude GitHub app must be installed on this repository first.

⏺ Ultraplan keeps hitting the same wall despite the app being installed correctly. This might be a transient
backend issue or something specific to newly created repos.

What Should Happen?

Ultraplan should launch
