This skill is limited to planning and scaffolding. It does not provide instructions or code for live provider execution. Never produce or modify code that: If a user asks for any of the above, stop and provide a security handoff note. - installs or imports an external provider SDK - reads or writes provider credentials/secrets - creates live checkout sessions - processes provider callbacks - performs live transaction state changes - Define provider-agnostic contracts ( CheckoutProvider interfaces). - Create mock server adapters with deterministic fake IDs. - Implement UI states and polling logic against mock status endpoints. - Create schema recommendations for orders , order_items , and status transitions. - Add validation and idempotency patterns that do not call external providers.
