Most recently I ask first CC to create a design document for what we are going to do. He has instructions to look into the relevant parts of the code and docs to reference them. I review it and few back-and-forths we have defined what we want to do. Next step is to chunk it into stages and even those to smaller steps. All this may take few hours, but after this is well defined, I clear the context. I then let him read the docs and implement one stage. This goes mostly well and if it doesn't I either try to steer him to correct it, or if it's too bad, I improve the docs and start this stage over. After stage is complete, we commit, clear context and proceed to next stage.
This way I spend maybe a day creating a feature that would take me maybe 2-3. And at the end we have a document, unit tests, storybook pages, and features that gets overlooked like accessibility, aria-things, etc.
At the very end I like another model to make a code review.
Even if this didn't make me faster now, I would consider it future-proofing myself as a software engineer as these tools are improving quickly
