AI agents call snow_get_instance_info 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 retrieves or queries ServiceNow instance metadata/configuration information. The verb 'Get' and context of instance information retrieval classify it as a Read operation. While instance information might include configuration details, the tool does not modify, create, delete, or execute anything—it only fetches data.
