setup

You are wiring the current target project so UIForge can source components cleanly through the shadcn registry. The shadcn MCP server (shipped by this plugin's .mcp.json) reads the registry list from this project's components.json — so registry entries must live here, in the target repo, not in the plugin. The default shadcn/ui registry needs no entry; the @motion-primitives registry does. Do the following, reporting each result. (For the design foundation itself — tokens, type, color — that's the uiforge:design-tokens skill; this command only prepares the plumbing.)

1. Confirm this is a shadcn project

• Check for components.json at the project root (ls components.json).
• If it is missing, tell the user this project isn't shadcn-initialized and offer to run npx shadcn@latest init (do not run it unprompted — it writes config and may pick a style/base-color). Stop here until they confirm.

2. Ensure the @motion-primitives registry entry

Open components.json. Ensure it contains a registries map with this exact entry (the URL is confirmed from Motion-Primitives' own installation-cli source — do not alter it):

{
  "registries": {
    "@motion-primitives": "https://motion-primitives.com/c/{name}.json"
  }
}

• If registries is absent, add it with this entry.
• If registries exists but lacks @motion-primitives, add the key — do not disturb other registries.
• If @motion-primitives already points at this URL, leave it and say so.
• {name} is a literal placeholder shadcn substitutes at install time (add @motion-primitives/text-effect → .../c/text-effect.json). Keep the braces.

3. Ensure runtime prerequisites

• Detect the package manager first from the lockfile so you never mix managers: pnpm-lock.yaml → pnpm, yarn.lock → yarn, bun.lockb or bun.lock → bun (Bun ≥1.2 writes the text bun.lock), else package-lock.json/none → npm. Use that manager's add syntax for every offer below (pnpm add …, yarn add …, bun add …, or npm install …).
• motion and lucide-react are installed (check package.json dependencies). If missing, offer to install them with the detected manager.
• A cn helper exists at the path this project's components.json aliases.utils resolves to (default lib/utils.ts). If absent, create it — match the project's language: for a TypeScript project write .ts; for a JS-only project (components.json has "tsx": false) write lib/utils.js with the type annotations dropped:
