Shadcn registry first

Darkmatter pays for the @shadcnblocks block registry and wires both it and the free @shadcn registry into the shadcn MCP. That means most common UI surfaces — heroes, navbars, footers, pricing tables, feature grids, dashboards, login screens, data tables — already exist as production-quality, accessible, themeable blocks you can install in one command. Reaching for them first is faster and produces better output than writing JSX from a blank file.

The default failure mode this skill corrects: an agent silently hand-rolls a hero or a pricing table that the registry already has, burning tokens and shipping something less polished. Before you write a new component from scratch, check whether the registry already carries it.
