// WHEN AI AGENTS USE THIS TOOL

AI agents may call delete_relations to permanently remove or destroy resources in Memento. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. Intercept blocks destructive tools by default and requires explicit human approval before enabling them.

// WHY ENFORCE A POLICY ON DELETE_RELATIONS

Without a policy, an AI agent could call delete_relations in a loop, permanently destroying resources in Memento. There is no undo for destructive operations. Intercept blocks this tool by default and only allows it when a human explicitly approves the action.

// RECOMMENDED POLICY

Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

memento.yaml

tools:
  delete_relations:
    rules:
      - action: deny
        reason: "Blocked by default — enable with approval"
