List all worksheets (tabs) in a spreadsheet with their properties.
AI agents call list_worksheets to retrieve information from Google Connections without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries metadata about existing worksheets without creating, modifying, or deleting any data. It is a straightforward read operation that retrieves information about spreadsheet structure. The low severity reflects minimal blast radius—even if misused by an agent, it only exposes worksheet names and properties, not sensitive cell data or destructive actions.
From the tool's definition Tool name is 'list_worksheets' and description states 'List all worksheets (tabs) in a spreadsheet with their properties.' The verb 'list' indicates a retrieval operation with no modification or side effects.
