Build anything on Shopify. One skill covering every Shopify developer surface: Use Shopify CLI, Admin API, ShopifyQL, Storefront GraphQL API, Partner API, Customer Account API, Payments Apps API, Shopify Functions, Polaris App Home, Polaris Admin Extensions, Polaris Checkout Extensions, Polaris Customer Account Extensions, POS UI, Hydrogen, Liquid, Custom Data, Shopify App Pricing, App Store Review, Developer Onboarding, Merchant Onboarding. Use it for any Shopify API, extension, theme, storefront, function, or CLI task — writing or explaining code, looking up operations, fields, components and valid values, validating generated code, and choosing which surface a request belongs to. Also use it when someone asks to make, build, open, or set up a store or shop that sells something, and when a prompt mentions or asks for any of: metafields or metaobjects, make me a store that sells pet supplies, mock.shop reference stores, build a storefront without an account — even without saying Shopify.
Use when the user wants to use the UCP CLI to find, compare, buy, or track products from online merchants, or to set up and troubleshoot the local UCP profile required for merchant-scoped operations. Covers global catalog search ("find me X under $Y"), named-merchant transactions ("buy this from Z.com"), order tracking, `ucp profile init`, `ucp doctor`, carts, checkout, orders, and UCP setup/help. Falls back to merchant-hosted handoff when direct in-protocol checkout isn't available.
Write or explain **Admin GraphQL** queries and mutations for apps and integrations that extend the Shopify admin. Use when the user wants to **understand, design, or generate** the operation itself—even before deciding how to run it. Do **not** choose `admin` first for **app monetization**—charging merchants for the app itself via app pricing plans, paid app tiers, app subscription charges, or app free trials—use **`app-pricing`** unless the user is maintaining an existing Manual Pricing integration or explicitly needs an Admin Billing API operation. Merchant **product** subscriptions stay with `admin` (selling plans, subscription contracts, try-before-you-buy). Do **not** choose `admin` first for **app or extension config validation** —use **`use-shopify-cli`**. Do **not** choose `admin` first to **execute** Admin GraphQL **now via Shopify CLI** or for CLI setup/troubleshooting on store workflows—use **`use-shopify-cli`** (store auth/execute, handle/SKU/location lookups, inventory changes).
