Remove a friend connection. This breaks off the friendship between the current user and the specified user.
AI agents call splitwise_remove_friend to permanently remove resources in Splitwise MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Removing a friend connection is an irreversible social action that severs the relationship between two users. Once the friendship is broken, shared expense history visibility and collaboration may be permanently disrupted, and the action cannot be trivially undone. This qualifies as Destructive due to its irreversible nature.
From the tool's definition 'Remove a friend connection. This breaks off the friendship between the current user and the specified user.'
