AI agents call delete_all_memories to permanently remove resources in RememberMe — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes all user memories without the ability to undo or recover the data. The blast radius is high because it eliminates the entire memory context for a user or session, potentially compromising the utility and continuity of the client's interaction history. The destructive category takes precedence over Write (its parent is clearly delete, not create/update).
From the tool's definition Tool name 'delete_all_memories' combined with sibling tool 'delete_memory' indicates irreversible deletion of all stored memory records. No description provided, but the name unambiguously conveys a destructive operation affecting the entire memory store.

{
"version": "1",
"default": "deny",
"hide": [
"delete_all_memories"
