Does this happen every time the agent attempts to run your build script? Or was this a one-time problem?

I'm guessing that your build script is either running indefinitely or is waiting for some interactive user input. If you invoke it manually, does it complete without asking for any input?

It's also possible that the build script is doing something that is blocked by the Codex sandbox mechanism. If you temporarily disable the sandbox, does that allow it to complete?

The problem is if I either run build with Cursor, Claude Code or just pure terminal, npm run build works. But just in Codex CLI, npm run lint works fine, but takes forever to run "npm run build".

It automatically runs lint and build as I request, but since it took too long I had to manually terminate it.

I thought about the sandbox issue but what's interesting is npm run lint works.

Thanks for the additional details. You'll likely need to do some debugging on your side to understand the issue better. There's unfortunately not much more I can discern from the logs. If you find any more clues (e.g. if the slowdown goes away when running outside of the Codex sandbox), please let me know.
