At least for me, I can have five of these processes running at once. I can also use Deepresearch for generating the designs with a survey of literature. I can use NotebookLM to analyse the designs. And I use Sourcery, CodeRabbit, Codex and Codescene together to do code review.

It took me a long time to get there with custom cli tools and browser userscripts. The out of the box tooling is very limited unless you are willing to pay big £££s for Devin or Blitzy.
