What issue are you seeing?

Codex is completely unable to use gh or git.

With default permissions, commands that do not require permissions to run do not work. Commands that ask for permissions work.

With full permissions, virtually nothing at all works. After going to great lengths to re-feed it my gh auth token, it's still unable to use git, running in circles about ACLs and sandbox permissions and writing increasingly convoluted scripts to try and simply check files in.

extent analysis

TL;DR

The issue may be related to permission settings, and adjusting the permissions or re-configuring the authentication token could potentially resolve the problem with Codex using git.

Guidance

  • Verify that the gh auth token is correctly configured and valid, as commands that require permissions seem to work.
  • Check the ACLs and sandbox permissions settings to ensure they are not overly restrictive, causing issues with git commands.
  • Try resetting the permissions to default and then gradually increase them to identify the specific permission causing the issue.
  • Re-evaluate the scripts generated by Codex to check files in, as they may be overly complex and contributing to the problem.

Notes

The provided image and quote do not offer technical insights into the issue, so their relevance is unclear. The problem seems to be related to the interaction between Codex, git, and permission settings.

Recommendation

Apply workaround: Adjust the permission settings and re-configure the authentication token, as this seems to be the most direct approach to resolving the issue with Codex using git.
