AI agents call sg_tourism_latest to retrieve information from Sgdata without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves tourism data for the most recent year from a Singapore government dataset. It performs a read-only query without creating, modifying, deleting, or executing operations. The blast radius of misuse is minimal—an agent could only access already-public tourism statistics.
From the tool's definition Tool name 'sg_tourism_latest' and description 'Get the most recent year' indicate data retrieval with no modification or side effects. The verb 'Get' and the singular data retrieval pattern align with query/fetch operations.
