Clear all completed tasks from a task list
AI agents call clear_completed_tasks to permanently remove resources in Google Connections — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently deletes all completed tasks from a task list. The operation is non-reversible and affects potentially many items at once. While the blast radius is limited to tasks (not financial or life-critical data), the destructive nature and bulk scope justify 'high' severity. Confidence is high because the description explicitly states clearing/deletion of task data.
From the tool's definition clear_completed_tasks: 'Clear all completed tasks from a task list' — uses 'clear' which irreversibly removes data in bulk without recovery mechanism
