AI agents call get_spreadsheet_info to retrieve information from Gg without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about spreadsheet structure and properties without creating, modifying, deleting, or executing any operations. It has no side effects and poses minimal security risk—metadata exposure is lower risk than data content access. Classified as Read with low severity due to limited blast radius if misused.
From the tool's definition Tool name is 'get_spreadsheet_info' and description states it retrieves 'metadata about a spreadsheet: title, sheets, and their dimensions.' The verb 'Get' and the focus on querying metadata without modification indicates read-only data retrieval.
