Run this before you write any UI component code. It searches the entire shadcn ecosystem (Magic UI, Aceternity, Tailark, AI Elements, all the registries) to find what already exists, not just what's in your components.json. The official shadcn skill installs things you've decided on. This one answers "wait, does this already exist somewhere?" When someone asks to build a table or modal or animated hero section, this checks first. It's the cheaper move. Ten seconds searching registries beats an hour building something that's been solved three times over. Works with the shadcn MCP when available, falls back to CLI search otherwise.
