  Two packaged skills covering the two things an agent actually does at this store: read the
  catalog, and transact. Every operation named in the frontmatter was verified present — tool
  names against a live tools/list response, GraphQL field names against the introspected
  QueryRoot and Mutation types. No operation is invented. Johnnie-O publishes no skills of its
  own; its llms.txt points agents at Shopify's cross-store skill at https://shop.app/SKILL.md,
  which is Shopify's artifact and is deliberately not copied in here.
