The other day I was doing something that required CC to update like 15-20 files in exactly the same way (hoist a specific function out of the component body) and instead of just updating the files, it spun up multiple agents, one of which wrote a perl script to hunt down all the files, do some regex, and replace all occurrences. And then instead of just running tsc to check for errors, it wrote a script to run tsc in each of the subagents and combine the results.
It was actually pretty maddening as what should have taken a minute or two tops took like 10 because it went down this route.
I'm gonna try something much more complex later, but for simple things, it felt like driving a corvette to the mailbox.
