Do **not** choose `admin` first for **app or extension config files** (`shopify.app.toml`, `shopify.app.<name>.toml`, `shopify.extension.toml`), pre-deploy config errors, or invalid TOML—use **`use-shopify-cli`** and **`shopify app config validate --json`** (no TOML validator here). 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).

NOT for Web Components - if the prompt mentions HTML tags like <shopify-store>, <shopify-cart>, use storefront-web-components instead.

Source

shopify-use-shopify-cli

skills/[email protected] by Shopify

Choose before `admin` 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`) with **`shopify app config validate --json`** (not Admin GraphQL; MCP has no TOML validator); run or troubleshoot store workflows (`shopify store auth`, `shopify store execute`); inventory or product changes by handle, SKU, or location name; or CLI setup, auth, upgrade issues. Emphasize **commands and operational steps**, not only authoring GraphQL. Skip for API-only understanding or codegen with no CLI execution. Examples: validate before deploy; run an existing query via CLI; list products; missing `shopify store execute`.
