AI loves inserting comments like this.

Either that or 20-line comments documenting the bugs in the old code, what this code does differently, and the exact implementation.

Comments describing the exact implementation become stale very quickly. Comments shouldn't explain what the code does (eg "add two to rowCount"); they should explain why it does it (eg "count for header and footer row too"). Extra details are what the commit message is for, and history is what source control is for.

I call it out in a lot of my code reviews ("code looks good but clean up the AI slop comments before landing") but a lot of other developers don't care as much about code and documentation quality.
