ANTI-SLOP — The Agent Design Playbook

We had AI build fictional storefronts - and they got caught by the gate, not the review. The ANTI-SLOP playbook: ten structural tells of AI-built UI, a ~1KB pre-prompt that stops slop before code exists, and a pass/fail acceptance gate that runs in a real browser and ships failure screenshots as receipts. 12 pages of teardowns with real screenshots. Grab the free 2-page extract first - if your AI output already passes it, you do not need the rest.
