AI agents call sku_quantity_available to retrieve information from Gobox without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves current inventory availability information for a SKU. It performs a read-only query operation with no side effects, modifications, or irreversible actions. The use of 'Get' and the passive nature of checking inventory levels confirm this is a Read category tool with minimal risk if misused by an agent.
