CODEX DOCTOR NOW READS THE ROOM

By RepoJournal ยท Filed ยท About OpenAI

Codex added environment diagnostics to its troubleshooting tool, finally giving support the terminal context needed to debug rendering issues across Windows, Linux, and macOS.

The `codex doctor` command [1] now captures OS language, Git metadata, Windows console mode, code page settings, and terminal title inputs that were invisible to support teams investigating TUI startup failures. This solves the diagnosis problem behind issue #23031 [1], where incomplete environment data made it impossible to reproduce terminal rendering regressions in the field. The change is read-only and ships as part of the existing doctor workflow, so it requires no behavior change from users. If you've submitted bug reports about terminal glitches, this update makes the next round of troubleshooting dramatically faster.
