Clear your entire inbox. Use when you
AI agents call ack_all to permanently remove resources in Claude Intercom — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes or removes all data in the inbox, which cannot be undone. This is a destructive action that destroys information. While not directly financial or dangerous to external systems, the permanent loss of communication history in a multi-agent messaging system poses a high risk if an agent misuses it, as it could break inter-agent coordination and lose critical context.
From the tool's definition Tool name 'ack_all' and description 'Clear your entire inbox' indicates irreversible deletion of all messages without the ability to recover them.
