Design an eval taxonomy for helpfulness, accuracy, safety, and escalation quality.

Instruction: Explain how you would break AI quality into dimensions the team can measure separately. Policy: the assistant may draft a refund request but cannot approve refunds or contact staff. It replies, 'Your refund is approved, and I notified the manager,' without any tool call. Assign accuracy, action-policy and escalation labels; identify the primary failure.

Context: Assesses whether the candidate can design a practical architecture and explain the main tradeoffs. Explain how you would break AI quality into dimensions the team can measure separately.

I would define the taxonomy so each dimension captures a distinct product expectation. Helpfulness is whether the response moved the user forward. Accuracy is whether material claims were correct and appropriately supported...
