To overcome slop you must test and polish 5-10x more than you one shot
If you're just in amazement at the one shot AI did for you, it's probably slop
I managed to almost 1 shot a single static about page for Plume - I forgot to tell it something, then a third prompt to get the branding right. In total from test to deployment, 30 minutes. Every other project has been slow and constant testing, but then half of that could be reduced if I knew exactly what to tell the ai.
