Design Exercise
Design an API-based agent that handles customer refund requests. The agent receives a refund request with an order ID and a reason.
- 1Tool list: Define three tools the agent needs (what APIs should they call?)
- 2Authentication: What authentication method would each API use?
- 3Error handling: List three error scenarios and what the agent should do in each
- 4Retry logic: Which errors should be retried? Which should escalate immediately?
- 5Output: What should the final observation look like when the refund succeeds?
- 6Human approval: At which step should the agent pause for human approval?
