Uizze gives coding agents a free anti-ui-slop Skill and optional full MCP access to live UI references, license-clear materials, and rendered safety checks. Use the skill to inspect the product and design system, write a design contract, cover required states, and run a bounded finish gate. The MCP answers one concrete unresolved UI question with strong full-screen references, finds license-clear materials for a concrete role, or optionally checks rendered UI for observable breakage, accessibility, privacy, and task-blocking composition. The free preview MCP exposes a deterministic source check only.
