I find the increased speed to be an opportunity to slow down and focus on certain things, particularly the architectural changes of the feature I'm looking to introduce.

If you're able to blaze through feature tickets using GenAI on existing projects of any major complexity, there's almost certainly something which would produce better code that you're skipping.

I have plenty of info and agents for Claude Code to take into account when I use it to make features in our projects, but what it can't know is the cadence of what our business partners expect, the unknown unknowns, conversations that humans have about the projects, and the way end-users feel about the project. My job is to direct it with those factors in mind, and the work to account for those factors takes time.
