Câu 30: CCA-F: Claude Certified Architect - Foundations

Your order management system requires tools for three distinct operations: issuing refunds (requires amount and reason), canceling orders (requires reason), and requesting reshipments (requires shipping address). Each operation shares an order_id parameter but has different additional requirements. You notice during testing that with your current unified tool design, the agent frequently omits required parameters or includes irrelevant ones. What design change will most effectively improve parameter accuracy?

1. A. Keep one unified tool with a nested operation_details object parameter whose internal structure varies by operation type, documented in the tool description.
2. B. Keep one unified tool but add JSON Schema if-then-else conditionals to enforce that parameters like amount are required only when the operation type is “refund”.
3. C. Split into three separate tools (issue_refund, cancel_order, request_reshipment), each defining only the parameters required for that specific operation. — đáp án hiện tại
4. D. Keep one unified tool with all parameters marked optional, but add detailed few-shot examples in the system prompt showing correct parameter combinations for each operation type.
