Of course vibe coding is going to be a headache if you have very particular aesthetic constraints around both the code and UX, and you aren't capable of clearly and explicitly explaining those constraints (which is often hard to do for aesthetics).

There are some good points here to improve harnesses around development and deployment though, like a deployment agent should ask if there is an existing S3 bucket instead of assuming it has to set everything up. Deployment these days is unnecessarily complicated in general, IMO.
