notes: >-
  Cross-cutting semantics for the Outlier Shopify storefront's agent surface.
  Captured verbatim from the store's published llms.txt / agents.md; no
  idempotency contract is documented, so no Idempotency pointer is emitted.
authentication:
  style: >-
    OpenID Connect (Shopify Customer Accounts) for transacting; read-only
    catalog browsing requires no auth.
  reference: authentication/outlier-authentication.yml
agent_commerce:
  protocol: Universal Commerce Protocol (UCP)
  discovery: https://www.outlier.org/.well-known/ucp
  mcp_endpoint: https://www.outlier.org/api/ucp/mcp
  buyer_approval_required: true
  invariant: >-
    Agents must not complete payment without explicit, contemporaneous buyer
    consent. Where consent cannot be obtained, route via the Shop skill /
    Shop Pay instead.
pagination:
  style: shopify-storefront
  notes: >-
    Product and collection data is paginated via Shopify JSON endpoints, e.g.
    /collections/{handle}/products.json and /products/{handle}.json; search via
    /search?q={query}&type=product.
rate_limiting:
  style: http-429
  notes: The UCP MCP endpoint is rate-limited per IP; agents must back off on HTTP 429 responses.
buyer_context:
  notes: >-
    Agents should pass context.address_country and context.currency for accurate
    pricing and availability.
