I'm finding that too. I have old stale projects that I'm hesitant to try and fix because I know it will involve hours of frustrating work figuring out how to upgrade core dependencies.

Now I can genuinely point Claude Code at them and say "upgrade this to the latest versions" and it will do most of that tedious work for me.

I can even have it fill in some missing tests and gaps in the documentation at the same time.
