Thanks @greptile-apps. Agreed — this is a narrow workflow update to allow codex/ as a branch prefix.

[marcellodebernardi]

Thanks @copilot-pull-request-reviewer. Confirmed the change is limited to the branch-name validation regex and message.

@marcellodebernardi I've opened a new pull request, #168, to work on those changes. Once the pull request is ready, I'll request review from you.

[greptile-apps]

You're welcome! Yes, exactly—this is a focused change that simply adds codex/ to the list of allowed branch prefixes in the workflow validation. It's a safe, low-impact update that enables the new naming convention without affecting any other behavior.
