You can spot AI-built UI from across the room.
Inter everywhere. Purple-to-blue gradients. Cards nested in cards. A rounded icon tile above every heading.
Every model trained on the same SaaS templates.
Impeccable gives your coding agent taste:
→ 24 design commands (polish, audit, critique, distill, harden...)
→ 61 slop detectors that run with no LLM, no API key
→ A hook that checks every UI edit while the agent works
→ PRODUCT.md first, so design starts from audience & purpose
