My process is just getting claude code to generate a plan file and then rinsing it through codex until it has no more advice left.

I'd consider it vibe-coding if you never read the code/plan.

For example, you could package this up in a bash alias `vibecode "my prompt"` instead of `claude -p "my prompt"` and it surely is still vibe-coding so long as you remain arms length from the plan/code itself.
