Initialize Vercel Shop

Ask for the target directory if the user did not provide one. Always pass it explicitly.

1. Inspect the target. If it already contains a Vercel Shop project, stop and use the relevant storefront skill instead. If it is a non-empty directory, ask for a different target rather than overwriting files.
2. Run:

   npx create-vercel-shop@latest <target-directory>
   

   
   Preserve an explicitly requested package manager with --use-pnpm, --use-npm, --use-yarn, or --use-bun.
3. Confirm the generated project contains .vercel-shop/bootstrap.json, AGENTS.md, app/, components/, lib/shopify/, and package.json.
4. Read the generated AGENTS.md before making further changes.
5. If the CLI reports a plugin installation failure, keep the generated project and show the matching retry command:

   npx plugins add vercel/shop --scope project --yes
   npx plugins add vercel/vercel-plugin --scope project --yes
   npx plugins add Shopify/shopify-ai-toolkit --scope project --yes
   

6. Ask one optional follow-up: Connect an existing Shopify store now?
   If yes, ask only for the store's admin URL or .myshopify.com domain, then read references/storefront-token.md and follow its automated Shopify CLI flow. Try to reuse or create a public Storefront token before asking the user to visit the Headless channel.
   If no, finish with the normal environment setup as the next step.

Return the generated project path, whether a Shopify store was connected, and whether plugin installation needs a retry.
