Agent assisted coding is just vibe-coding in disguise. You still only glance over the code "just so it won't be considered vibe-coding", but at the end of the day, if you invest a proper amount of time reading and reasoning with the generated code - than it would take the exact same time, as if you would have wrote it by hand.

By not going through this process, you loose intent, familiarity, and opinions.

It's the exact same as vibe-coding.
