Nothing as heavy as the above but here's my small anecdote:

I was putting off security updates on my npm dependencies in my personal project because it's a pain to migrate if the upgrade isn't trivial. It's not a critical website, but I run npm scripts locally, and dependabot is telling me things.

I told Claude Code to make a migration plan to upgrade my deps. It updated code for breaking changes (there were API changes, not all fixes are minor version upgrades) and replaced abandoned unmaintained packages with newer ones or built-in Node APIs. It was all done in an hour. I even got unit tests out of it to test for regressions.

In this case, I was able to skip the boring task of maintaining code and applying routine updates and focus on the fun feature stuff.
