My recent experience demonstrates this. I had a couple weeks of happily cranking out new code and refactors at high speed with Claude’s help, then a week of what felt like total stagnation, and now I’m back to high velocity again.
What happened in the middle was I didn’t know what I wanted. I hadn’t worked out the right data model for the application yet, so I couldn’t tell Claude what to do. And if you tell it to go ahead and write more code at that point, very bad things will start to happen.
