Sample question

Agentic Architecture & Orchestration

A travel company builds a booking assistant directly on the Claude Messages API with four client tools. Its loop ends as soon as a response contains any text block. In testing, the assistant often replies "Let me check the available flights" and the conversation stops there, with no flight search ever executed. How should the loop's control flow be changed?

  1. End the loop after a fixed number of rounds based on the average length of past sessions
  2. End the loop only when Claude's text contains an agreed phrase such as "TASK COMPLETE"
  3. Keep looping while stop_reason is "tool_use", sending back tool_result blocks each round
  4. End the loop when a response contains a text block and no more than one tool_use block
Show the answer and the explanation

Correct answer: C

When Claude wants a client tool, the response carries stop_reason "tool_use" plus tool_use blocks; the application must run the tools, return the results and call the API again. The loop only finishes when Claude produces output with no tool calls.
