Same experience here - I built a similar tool, for reviewing both plans and code - https://crit.md (shameless plug), browser based as opposed to TUI.

Having said that, I don't review the code until going through a few iterations of reviews from Claude. Each round it does find some "obvious" issue, so as long as I'm not close to maxing my subscription for the week I let it run an audit -> validator checks the claims -> fix issues before I get to it.
