Identify and prevent AI design slop in generated UI -- forbidden visual tells (purple/teal gradients, generic system emoji, soft pastel everything, fake metrics, hand-drawn cartoon humans, rounded-2xl-everywhere) and enforce honest placeholders. Use after generating any HTML/CSS prototype, marketing surface, or…

Extract and codify a brand specification from user-provided sources (URL, screenshot, PDF, existing app) into a deterministic brand-spec.md artifact. Captures palette, typography, voice, motion, and prohibited patterns so downstream design decisions can be defended against the real brand instead of invented from…
