Thread title is auto-generated with malformed/error-like text (e.g. _invalid correction, Oops invalid JSON? I)

What version of the Codex App are you using (From “About Codex” dialog)?

What subscription do you have?

Pro

What platform is your computer?

Darwin 25.3.0 arm64 arm

What issue are you seeing?

In the thread list, some conversation titles are automatically saved with malformed suffix text that looks like parser/correction output, instead of a clean summary of my prompt.

What steps can reproduce the bug?

1. Open Codex desktop app and create a new thread.
2. Ask Codex to perform a task that may trigger tool/runtime errors (in my case: creating a new skill).
3. Let the run hit an error-like response (examples I saw: missing dependency message like PyYAML not installed, or a fork/collab-related error during git/fork workflow).
4. Return to the thread list and check the auto-generated title.
5. Sometimes the title is corrupted with error/correction-like fragments instead of a clean summary.

It occurs intermittently. My guess is that it tends to happen when an error occurs in the thread.

What is the expected behavior?

Thread title should always be a clean natural-language summary of the conversation, without parser/correction/error-like fragments.
