That is actually a gold tip. Codex CLI is way less pleasant to use than Opus, but way better at finding bugs, so I combine them.

Codex is a sufficiently good reviewer I now let it review my hand-coded work too. It's a really, really good reviewer. I think I make this point often enough now that I suspect OpenAI should be paying me. Claude and Gemini will happily sign off work that just doesn't work, OpenAI is a beast at code-review.
