AI agents call reference_get_cargo_description_list to retrieve information from Novaposhta without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves predefined reference data (cargo descriptions) without modifying any state or triggering external operations. The recommendation to cache monthly further confirms it serves as a read-only reference. No side effects, data persistence changes, or external operations are possible. Misuse would at worst retrieve unwanted reference information, posing minimal risk.
From the tool's definition Tool name contains 'get' and description explicitly states 'List cargo descriptions' and 'Returns predefined descriptions'. The verb 'List' and 'Returns' indicate data retrieval with no modification capability.
