Alright, after a full week with Codex, I understand why folks like @chris_mccord and @antirez have been praising it.
It’s far more thorough than Claude Code. When you ask for a change, it does a better job of understanding the system and the different areas that will be affected.
The only downside is that it can sometimes overreach on smaller changes, but that’s partly because I’ve been feeding it piecemeal requests. I’m starting to trust it with larger tasks now, something I didn't feel much comfortable before.
