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.

❯ ultraplan: cannot launch remote session —
The Claude GitHub app must be installed on this repository first.
https://github.com/apps/claude/installations/new

⏺ 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

Error Messages/Logs

Steps to Reproduce

Try to start ultraplan when Claude Code has not yet created a repository. Claude then creates the repository. Ultraplan will refuse to load.

TL;DR

The issue might be resolved by ensuring the Claude GitHub app is properly installed and configured for the repository, and then retrying the ultraplan launch.

Guidance

  • Verify that the Claude GitHub app is installed and authorized for the specific repository by checking the repository settings and the app's installation page.
  • Check the repository's permissions and access controls to ensure that the Claude GitHub app has the necessary permissions to operate.
  • Try restarting the ultraplan session or reloading the repository to see if the issue persists.
  • If the issue is intermittent, it may be related to a transient backend issue, so retrying the launch at a later time might resolve the problem.

Notes

The provided information suggests that the issue might be related to the app's installation or configuration, but without more detailed error logs or debugging information, it's difficult to pinpoint the exact cause.

Recommendation

Apply workaround: Retry the ultraplan launch after verifying the app's installation and configuration, and check the repository's permissions and access controls.
