AI agents call cart_rule_get to retrieve information from Voog without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves a cart rule by identifier using a GET request. It performs no modifications, deletions, or financial transactions—purely a read operation querying existing ecommerce configuration data. The blast radius of misuse is minimal (information disclosure of cart rule settings).
