I do the same, and have excellent results. Gemini 3.1 Pro high diagnosed and solved 3 complex issues today that Opus Max was stumbling on for a few hours in one shot. This was even when I started new chats and tried debugging with Ultracode instead with Claude.

As much as people on HN like to dunk on Gemini, I’ve always found it to be pretty good at understanding a code base more than Claude.

What harness do you use Gemini in?
