Check storage quota usage across users
AI agents call check_storage_usage to retrieve information from Google Workspace Compliance Audit Tool 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 storage quota data across users for audit and compliance reporting purposes. It has no side effects, does not modify or delete data, and does not execute external operations. It is purely informational, consistent with other audit tools on this server (check_2fa_status, check_admin_roles, check_api_access, etc.) that read configuration and status data.
From the tool's definition Tool name 'check_storage_usage' and description 'Check storage quota usage across users' indicate a query operation that retrieves and reports storage metrics without modifying, deleting, or executing any operations.
