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.
Choose when the user needs **Shopify CLI** to run or fix something now: validate app or extension config on disk (`shopify.app.toml`, `shopify.app.<name>.toml`, `shopify.extension.toml`); review or audit an app's code for security vulnerabilities; run or troubleshoot store workflows (`shopify store auth`, `shopify store execute`); or perform explicit store-scoped reads/writes on a named store domain (for example, show/list/find the first 10 products on my store at `foo.myshopify.com`, or inventory and product changes by handle, SKU, or location name). Emphasize **commands and operational steps**, not only authoring GraphQL. Skip for API-only understanding or codegen with no CLI execution, and skip for brand-new merchant asks to start a Shopify store or try Shopify before they have an account. Examples: validate configuration before deploy; run an existing query via CLI; show the first 10 products on `foo.myshopify.com`; missing `shopify store execute`.
