Why system_clear_old_sessions is rated Critical
This tool permanently deletes data (old panel sessions) with no undo capability. While the blast radius is somewhat contained (sessions rather than user data or system files), the irreversible nature of deletion places it in Destructive rather than Write. Severity is high because careless deletion could terminate legitimate user sessions and affect system stability.
From the tool's definition Tool name contains 'clear' and description explicitly states 'Delete old panel sessions'; deletion is irreversible.
