[BUG] Ultraplan fails to recognize allowed git repo (first use on repo).

What's Wrong?

Claude CLI fails to connect to a repo for ultraplan. Claude CLI interacts fine with git in other repos, and interacts fine with this repo. It is not a git permissions issue - I have tried "All repos" and selecting specific ones. No difference.

What Should Happen?

I have been using claude code to establish a new repo/codebase. I did a git commit and the work so far is saved in git. Claude has the correct permissions to use git fully (it does so fine on another repo). I am trying to launch ultraplan and it says it does not have access to the repo. I have tried (inside git permissions for claude) to use "all repos" and also to select specific repos. It makes no difference, Claude thinks it does not have access. I showed it a screenshot and it agreed this was a bug.

⏺ Let's verify the app is actually installed. Open this in your browser:
  
  https://github.com/settings/installations

  You should see "Claude" listed under Installed GitHub Apps. If it's there, click
  Configure and confirm reponame is included under repository access. If it's
  not listed at all, visit https://github.com/apps/claude/installations/new and complete
   the full install flow (authorize → select repo → click the green Install button at
  the bottom).

⏺ Try clicking Configure on the Claude app at https://github.com/settings/installations,
   then under Repository access switch from "All repositories" to "Only select 
  repositories", add reponame explicitly, save — then switch back to "All
  repositories" if you prefer. This forces a permission refresh on the specific repo.

  Then retry /ultraplan.

⏺ Let's verify the installation is on the right account. Check this URL directly:

  https://github.com/organizations/redacted/settings/installations
  
  Or if that 404s (meaning it's a personal account, not an org):
  
  https://github.com/settings/installations

  Click Configure next to Claude and confirm:
  1. It's under account redacted (not a different account or org)
  2. reponame is listed under repository access
  
  If the app is installed under a different GitHub account than the one that owns
  redacted/reponame, that would explain the persistent failure — the app
  installation and the repo need to be on the same account.

✻ Churned for 16s

❯ can you see the photo on the clipboard? it shows the adccount and that the repo is    
  allowed.                                                                              
  
⏺ I can't access your clipboard directly — paste or drag the image into the chat and
  I'll be able to see it.

❯ [Image #1]                                                                            
  ⎿  [Image #1]

⏺ The installation looks correct — reponame is listed. One thing I notice:
  scroll down on that page and check if there's a green Save button at the bottom. If
  you added the repo to the list but didn't click Save, the access grant wasn't
  committed. Click Save if it's there, then retry /ultraplan.

✻ Worked for 21s

❯ I reloaded the page after going elsewhere in git. it is saved.                        

⏺ Bash(git -C /Users/redacted/Documents/reponame remote -v)
  ⎿  origin     https://github.com/redacted/reponame.git (fetch)
     origin     https://github.com/redacted/reponame.git (push)

⏺ Remote is correctly set. This looks like it may be a propagation delay or a bug in
  Ultraplan itself — everything on your end is configured correctly. Try waiting 1-2
  minutes and running /ultraplan once more. If it still fails, this is likely a
  platform-side issue worth reporting at
  https://github.com/anthropics/claude-code/issues.

✻ Baked for 16s

※ recap: We're auditing the reponame codebase and trying to launch Ultraplan 
  for remote plan refinement. The GitHub app is installed and configured correctly — 
  just retry /ultraplan now. (disable recaps in /config)

Steps to Reproduce

use /ultraplan in Claude CLI. It will not run, see above outputs.
