A vibe is intuition, so it can't be too much, else it isn't vibe coding. However, the intuition that comes after taking some time is different than after a quick glance. For instance if you read a pull request and then immediately decide after reading it at a measured space that would be different than after skimming it. So yes, Looks OK to me right now, or LGTM, as in a pull request, is what I have in mind.
