> LLM-written ones are almost entirely additive

I have noticed Claude's extreme and obtuse reluctance to delete code, even code that it just wrote that I told it is wrong. For example, it might produce a fn:

   fn foo(bar)

And then I say, no, I actually wanted you to "foo with a frobnitz", so now we get:

   fn foo(bar) // Never called
   fn foo_with_frobnitz(bar)
