How would you design safeguards for an AI system that can take actions on behalf of a user?

To design safeguards for an AI system acting on behalf of a user, I would implement a multi-layered approach focusing on control and transparency.

1. Strict Permissions and Read-Only Default: The AI agent should operate in a read-only mode by default. Any action requiring modification or execution must be explicitly enabled and tightly controlled.
2. User Confirmation Workflow: For any action that modifies data or performs an operation, a robust user confirmation step is essential. This ensures the user is aware and explicitly approves the action before it's executed.
3. Idempotent Action Keys: Implement a system where each actionable request is associated with a unique, unguessable idempotent key. This key should be generated by the orchestrator and required as an argument for action execution. The AI model should not be able to generate or bypass this key, reinforcing that it's a control mechanism outside the model's direct influence.
4. Orchestration Layer Control: All critical logic, including permission management, confirmation workflows, and key generation/validation, should reside in the orchestrator layer. The AI model's role should be limited to suggesting actions or providing information, treating it as a 'dumb' component that relies on the orchestrator for execution and safety.
5. Auditing and Logging: Maintain detailed logs of all AI suggestions, user confirmations, and executed actions for accountability and post-incident analysis.
