v0.6.3

Patch Changes

• cc166b2: Correct and clarify the bundled UCP agent skill's Shopify Global Catalog guidance:

  • Seller identity: match a buyer-named brand or first-party store on seller.url (the buyer-facing storefront); seller.domain is the permanent handle for addressing the API (--business), not a brand signal.
  • Checkout: eligible.native_checkout indicates whether a checkout can be finalized in-protocol — false still supports building and negotiating a cart/checkout in-protocol, with finalizing handled via escalation (continue_url); it is not a redirect-only dead end.
  • Currency: prices are returned in each seller's market presentment currency (keyed off context.address_country), so a result set can span multiple currencies — read price_range.min.currency per item.
  • get_product: copy selected option names/labels verbatim from the response's options[]; options may be null (no variant picker — use the featured variant or hand off to the product url).
  • filters.attributes: names/values come from the Shopify Standard Product Taxonomy (category-specific; canonical name or GID), with a pointer to the public taxonomy.

  Also consolidates the duplicated response-field documentation into references/CATALOG.md.
