Two related defects encountered while trying to use /ultrareview against PRs in my own GitHub repo:

  1. /install-github-app opens an interactive dialog that cannot be dismissed: ctrl-c, esc, and enter all do nothing. I had to ctrl-z the process and kill %1 to escape.

  2. /ultrareview <PR#> fails with a single error string regardless of which piece is misconfigured:

    Ultrareview could not start the remote session: GitHub repository access check failed — re-authorize GitHub in settings

    The error gives no signal on which of these is missing:

    • The claude GitHub App (https://github.com/apps/claude) installed on the repo
    • Claude.ai-side OAuth grant (the fix in my case was /logout && /login)
    • gh CLI auth
    • The CLI's local OAuth store
    • Repo allow-list scope inside the App install

    I had to try each of them in turn to isolate the cause. /config does not surface a GitHub integration row, so there's no "current status" to inspect.

Summary

Two related defects encountered while trying to use /ultrareview against PRs in my own GitHub repo:

  1. /install-github-app opens an interactive dialog that cannot be dismissed: ctrl-c, esc, and enter all do nothing. I had to ctrl-z the process and kill %1 to escape.

  2. /ultrareview <PR#> fails with a single error string regardless of which piece is misconfigured:

    Ultrareview could not start the remote session: GitHub repository access check failed — re-authorize GitHub in settings

    The error gives no signal on which of these is missing:

    • The claude GitHub App (https://github.com/apps/claude) installed on the repo
    • Claude.ai-side OAuth grant (the fix in my case was /logout && /login)
    • gh CLI auth
    • The CLI's local OAuth store
    • Repo allow-list scope inside the App install

    I had to try each of them in turn to isolate the cause. /config does not surface a GitHub integration row, so there's no "current status" to inspect.

Repro (issue 1 — freeze)

  1. Run /install-github-app in the REPL.
  2. Dialog renders. No key (ctrl-c, esc, enter, q) closes it.
  3. Only ctrl-z + kill %1 recovers.

Terminal: standard Linux terminal (Ubuntu 25.10, kernel 6.17.0-20-generic). Claude Code 2.1.119.

Repro (issue 2 — opaque error)

  1. Install https://github.com/apps/claude on the target repo.
  2. Run /ultrareview <PR#> against a PR you own.
  3. Error fires. There is no diagnostic that distinguishes "App not installed" from "Claude.ai OAuth stale" from "wrong account" from "repo not in App allow-list".

In my case the actual fix was /logout && /login, which I only found after several other dead ends.

Suggested fixes

  • Freeze: make ctrl-c always dismissable in /install-github-app.
  • Error: have the access check report which specific precondition failed (App install, OAuth grant, repo scope, account match), and link to a specific remediation. A /ultrareview --doctor style command would also help.

Environment

  • Claude Code 2.1.119
  • Linux 6.17.0-20-generic x86_64
  • bash

extent analysis

TL;DR

To resolve the issues with /ultrareview, try checking the installation of the claude GitHub App, ensuring a valid Claude.ai-side OAuth grant, verifying gh CLI authentication, and confirming the repo's allow-list scope.

Guidance

  • Verify that the claude GitHub App is installed on the repository and that the repository is in the App's allow-list scope.
  • Check the Claude.ai-side OAuth grant by running /logout && /login to ensure a valid authentication.
  • Confirm that gh CLI authentication is properly set up and that the CLI's local OAuth store is correctly configured.
  • Consider using a diagnostic command like /ultrareview --doctor to identify specific preconditions that may have failed.

Example

No specific code snippet is provided as the issue is more related to configuration and authentication rather than code.

Notes

The provided information suggests that the issues are related to configuration and authentication rather than a code problem. Therefore, the focus should be on verifying and correcting the setup of the GitHub App, OAuth grants, and CLI authentication.

Recommendation

Apply the suggested fixes by checking the installation of the claude GitHub App, ensuring a valid Claude.ai-side OAuth grant, and verifying gh CLI authentication, as these steps directly address the reported issues and can help resolve the problems encountered with /ultrareview.
