80% of My Vibe Coding Was QA, Not Vibing

I built a production app entirely through an agent. The "vibe" part—describing what I wanted—was maybe 20% of the work.

The other 80% was the same discipline as any build. Catching a timezone off-by-one. A file upload limit rejecting real photos. Missing auto-capitalization. Refusing to accept "it's fixed" without proof.

Vibe coding didn't skip the engineering. It relocated it. Instead of writing code, I was writing precise instructions and doing QA like a hawk.

Has your split matched that, or did you find a different bottleneck?
