I usually use one instance, sometimes two. But this is a reasonable account of Chris Rackaukas using 32 instances at a time to do boilerplate maintenance across a bunch of open source repositories: https://www.stochasticlifestyle.com/claude-code-in-scientifi...

> I have had to spend like 4am-10am every morning Sunday through Saturday for the last 10 years on this stuff before the day gets started just to keep up on the “simple stuff” for the hundreds of repos I maintain. And this neverending chunk of “meh” stuff is exactly what it seems fit to do. So now I just let the 32 bots run wild on it and get straight to the real work, and it’s a gamechanger.
