material-3-skill bakes MD3 rules into Claude Code

This is less a generic “design prompt” and more a codified design system pack for agents, which is the right direction if you want AI-generated UI that stops drifting into generic slop.

• –The Compose-first stance matters: it anchors the skill to the most current Material 3 implementation path instead of hand-wavy cross-platform advice
• –The token coverage is the real value, because MD3 quality usually breaks at color roles, shape, and typography before it breaks at components
• –The audit mode is practical; it turns style guidance into something closer to a lint pass for UI conformity
• –The explicit note that web support is limited and Material Web is in maintenance mode is a useful constraint, not a flaw
• –If teams adopt skills like this broadly, the bottleneck shifts from “can the model generate UI?” to “did it follow the design system correctly?”
