Not sure if I do anything wrong but Codex with Sol made such slow progress on my work, I iterated several days to do a redesign of my UI and it kept making small piecemeal changes then stopping and asking me for confirmation again and again even though I tried to get it to get bigger chunks done. Switched to Claude Code and had the redesign done in a short session within a day.

Maybe just the system prompt or my settings or the harness? Anyway, it seemed to me Codex was just deliberately being overcareful and wasting tons of tokens for a low-risk CSS / HTML refactoring with very minor breakage risk, while Claude got the job done immediately.
