I think you don't understand what the interactive declaration is for.

It doesn't mean "this code interacts with the user".  It means it can be
invoked as a command, with a keybinding or via M-x.  In your case,
you're calling your function from a hook, which is as non-interactive as
it gets :-)

When we clarify that point, we can get to _how_ to use interactive; you
don't do that right either, even if it made sense to provide the
function as a command.
