I read it as "while Claude is actively working on this particular file, I do not touch that file".

Wait, that is completely different from what you said earlier.

"if you don't tell Claude, it will override your change"

Agentic tools do this today.

imagine this, if you set a goal for a robot to build a 9th storeys building, later you interject mid way to build up to 15 storeys. When the robot resumes its task, of course the robot is going to destroy the higher floors to meet its original goal of building to 9th storeys.

what else should we expect here?

the right to do before hitting the resume button is to "communicate" this new intention again.

it is not about being afraid of things
