I use it like having a bunch of L3/L4 engineers. I give them a description of the changes I want to be made, sometimes chat a bit with it to help them design the features and then tell them to have a go at it. Then I create PRs and review them and have them clean up/improve the code and merge it. I try to balance giving it enough stuff to build so I can switch to another agent, and not giving them too much so that they make a weird assumption and run really far with it.

I got really good at reviewing code efficiently from my time at Google and others, which helps a lot. I'm sure my personal career experience influences a lot how I'm using it.

FWIW, I use Codex CLI, but I assume my flow would be the same with Claude Code.
