Cursor AI is a productivity multiplier in the same way an espresso machine is — it makes the rote parts faster, but it does not decide what kind of coffee shop you are running.
What I let it do
Boilerplate. Type definitions from API responses. Test scaffolds. Refactors that are mechanical (rename, extract, inline). First-pass component drafts I will rewrite half of anyway.
What I do not let it do
Architecture. Trust decisions (auth, payments, security). Database schemas. Anything I have not read line-by-line. Code review of my own code — that has to come from a human, even if it is just future-me at 6am.
