What issue are you seeing?

On two separate macOS machines running the same Codex App version, Settings > Configuration > Import external agent config shows a different number of import options.

On one machine, the UI shows 3 options:

• Config
• Skills
• Plugins

On the other machine, the UI shows 4 options:

• Config
• Skills
• Plugins
• AGENTS.md

The difference is the AGENTS.md import option. The behavior is inconsistent even though the app version is the same.

This makes it unclear whether:

• the app is intentionally hiding AGENTS.md when import detection fails, or
• detection is failing silently on one machine.

I am intentionally omitting usernames and local filesystem paths from this report.

What steps can reproduce the bug?

1. Use Codex App version 26.417.41555 (1858) on two macOS machines.
2. On both machines, open Settings > Configuration.
3. In the Import external agent config section, compare the available import items.
4. Observe that one machine shows 3 items and the other shows 4.

In my case, the missing item on one machine is AGENTS.md.

What is the expected behavior?

The UI should behave consistently across machines running the same version.

If AGENTS.md import is a supported migration target, it would be better to either:

• show it consistently, or
• show it in a disabled/unavailable state with an explanation of which prerequisite is missing.

If the option is intentionally conditional, the UI should explain why it is hidden instead of silently omitting it.

Additional information

This may be a detection bug around migration eligibility for AGENTS.md / CLAUDE.md import.

If the current behavior is intentional, the settings UI could still be improved by exposing all possible import targets and clearly indicating which ones are unavailable and why.
