What I had in mind was the kind of bug our scripts/coccinelle/ rules look for.

I agree that fixing the interface is better, but do we want to push all these
agents there?

So I think it should be a balance. When the skill finds the same defect
in several places, it should also ask whether the interface invites the
mistake, and if so report that the fix belongs there instead of handing
back a list for N maintainers

What do you think?
