Delete an attribute from an instance. Args: - path (string): Instance path - name (string): Attribute name Returns: Confirmation message.
AI agents call delete_attribute to permanently remove resources in Melo — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes an attribute from a Roblox instance. Deletion is irreversible and cannot be undone through normal means. While the blast radius is constrained to a single attribute on a single instance (not system-wide), the destructive nature of the operation and its use in an agentic context where an AI could target wrong instances or attributes makes this high severity.
From the tool's definition Tool name 'delete_attribute' with description 'Delete an attribute from an instance.' The verb 'Delete' indicates irreversible removal of data.
