I still review the diff, or at least parts of it, but I agree with the article on reviewing intent, even put together a tool whose purpose is to organize the changes by intent (some examples here: https://sshah03.github.io/perspica/)
Basically they shift the process into the code generation by abstraction. But if agents write intent and acceptance criteria into the PR, and this seems to be the case, the point is moot, really. Either you check them there or in the PR and if the code change is acceptable still needs sb to decide.
