AI agents call snow_search_catalog to retrieve information from Serac without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a query-like operation that retrieves information about available service catalog items. It has no capability to modify, delete, or execute actions—it only reads and returns catalog data. This is a classic Read category operation with minimal risk if misused by an agent, as the worst case would be retrieving unwanted catalog information.
From the tool's definition Tool description explicitly states it 'Searches service catalog for items, categories, or catalogs' and 'Returns available items for ordering.' The verb 'searches' and 'returns' indicate data retrieval with no modification or side effects.
