I'm not the first person to say Agile is perfect, but Agile fixes this. "These are my tasks for this sprint. If you want me to do that task, we have to have a meeting to find out what I wont have time for".

No, agile doesn't. It's not a process problem, it's a people problem. People still overcommit in agile, or commit for the wrong reasons.

+1 for "which other thing should I not get done?"

Not a confrontational question, just a logical one.
