You'll notice
GitHub-app-missing error message now shows the server's own wording when available
What
When Claude Code reports that the Claude GitHub app isn't installed, it now checks for a message sent by the server (serverMessage) and shows that exact text first, only falling back to its generic built-in instructions if the server didn't provide one.
Why
This lets the server give more specific or up-to-date instructions for fixing a missing GitHub app installation, instead of users always seeing the same generic message.
