anti-slop skillA

anti-slop is agent-read markdown (skill) from gesso-build/skills: Deterministic design critique for HTML/CSS screens. Runs 73 slop guards extracted from the set of rules professional designers use in production-grade designs to catch the tells that make UI read as AI-generated (gradient-clipped headlines, the default indigo accent, puffy shadows, emoji icons, fake dot charts and decorated gauges, badges floated over the hero, eyebrow kickers above the H1, fake magazine mastheads, colored edge-stripe rails, two-tone headlines, over-designed list rows, layout-co.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
