    "incantation": "When debugging an Admin API query in Shopify CLI GraphiQL, add `Shopify-Search-Query-Debug=1` in the header editor to forward that custom header to the Admin API. The editor is enabled in CLI GraphiQL; safe custom headers are forwarded while filtered headers are blocked.",

      "Prerequisite: Use Shopify CLI's local GraphiQL instance while running `shopify app dev`; it authenticates as the app and has the app's access scopes.",
      "Prerequisite: The app must be installed on the store.",
