AI agents call sg_net_formations 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 and calculates aggregate metrics (net formations) from public government data sources. It is a read-only query operation with no side effects, no ability to modify underlying data, and no destructive or financial implications. The low severity reflects that misuse would only result in potentially accessing or analyzing publicly available statistical information without causing harm.
