Identify user accounts that have not logged in for 90+ days
AI agents call check_inactive_accounts 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 queries and retrieves information about user account login activity to identify inactive accounts. It performs data retrieval and analysis without creating, modifying, deleting, or executing operations. The severity is medium because exposure of inactive account lists could inform targeted phishing or account takeover attacks, but the tool itself only reads data and does not modify or delete anything.
From the tool's definition Tool name 'check_inactive_accounts' and description 'Identify user accounts that have not logged in for 90+ days' indicates a read-only query operation that retrieves account status data without modification, deletion, or execution of external operations.
