Their sample prompt takes me back a year or two:

> Find unused code in our web app. Exclude generated files and test fixtures, and check for indirect references before recommending a removal.

If I "/goal remove unused code" in Claude today, I would not even think to specify "check for indirect references" and "don't consider generated code dead code," those sorts of intuitions have been "built in" to the frontier models for a while now.

So I'm pretty confused by this, what does it do that I can't with an agent swarm?
