Having used agents some I think 'addictive behavior' is really the closest thing to the feeling it gives me as well. I don't find it engaging my critical thinking brain, and in fact it often subverts that in favor of 'get the next dopamine hit faster' behavior (ie just rerun it, leading to the metaphor the OP is using). It takes a conscious effort for me to get back out of that cycle and start thinking of the fine details of what the code really does, or why I wanted it to do that in the first place. I have called it 'smoking vibes' and 'chasing rAInbows' in my sillier moments. It really does feel good... too good :P
