When designing the role of the coordinator agent in a multi-agent system, which of the following practices are recommended? Choose 2 correct answers.
- A . Routing all inter-subagent communication through the coordinator to maintain observability and consistent error handling.
- B . Analyzing query requirements and dynamically selecting which subagents to invoke rather than always routing through the full pipeline.
- C . Forcing all queries through a flat architecture pipeline to maximize cross-agent state sharing.
- D . Decomposing broad research topics into overly narrow subtasks to save context tokens at the risk of coverage gaps.
Your team wants to use the Message Batches API to reduce costs by 50%. The pipeline includes a real-time blocking pre-merge code review and a nightly technical debt audit.
How should you apply the Batch API?
- A . Use the Batch API for both workflows to maximize cost savings.
- B . Use synchronous API calls for both workflows since the Batch API lacks JSON schema support.
- C . Use the Batch API strictly for the nightly audit, and retain synchronous calls for the blocking pre-merge review.
- D . Switch both to the Batch API but implement a timeout fallback to synchronous calls if it exceeds 5 minutes.
When designing JSON schemas for structured data extraction, which practices help prevent hallucinations and misclassifications? Choose 2 correct answers.
- A . Using nullable fields (e.g., ["string ," "null"]) when data might be absent from the source.
- B . Omitting the required array entirely to provide maximum generation flexibility.
- C . Using an other enum value paired with a detail string field for extensible categorization.
- D . Setting tool_choice: "auto" to allow conversational bypass when data is unclear.
A customer support agent handles high-ambiguity requests.
Which of the following is a valid, architecturally sound trigger for escalating a case to a human agent?
- A . The customer exhibits highly negative sentiment.
- B . The model’s self-reported confidence score drops below 0.7.
- C . The agent detects a policy gap not covered by its existing rules.
- D . The conversation exceeds 10 turns.
What is the primary risk associated with applying progressive summarization techniques to a long-running customer support session?
- A . It bypasses the stop_reason logic of the agentic loop.
- B . It frequently causes the Token Context Window to exceed maximum limits.
- C . It silently condenses and loses critical specific details such as dates, exact amounts, and unique IDs.
- D . It forces the agent to use tool_choice: "auto".
When implementing a multi-agent research system for a enterprise application, a coordinator agent must delegate a market analysis task to a specialized subagent.
What is the correct approach for passing context to this subagent?
- A . Share the entire coordinator conversation history to ensure the subagent has maximum context.
- B . Allow the subagent to access a shared global state object where the coordinator writes its findings.
- C . Pass only the specific, explicit context relevant to the subagent’s assigned subtask in the prompt.
- D . Use the /compact command to summarize the coordinator history before passing it to the subagent.
Which of the following tasks is the MOST appropriate use case for Direct Execution rather than Plan Mode?
- A . Changing the state management library from Redux to Zu stand across a large React application.
- B . Designing an implementation approach for a new API integration with unknown dependencies.
- C . Fixing a specific bug with a clear stack trace in a single TypeScript file.
- D . Restructuring the database schema and updating all corresponding repository models.
What is the primary architectural difference between handling a transient error and handling a valid empty result within an MCP tool’s response payload?
- A . Transient errors use is Error: true with a specific error Category, while empty results use is Error: false and return an empty data array.
- B . Transient errors must bypass the MCP client and communicate directly via WebSockets, whereas empty results use standard HTTP.
- C . Transient errors require the agent to spawn a subagent for resolution, whereas empty results are handled in the main thread.
- D . There is no difference; both scenarios should return a generic HTTP 404 response.
What is the only reliable, deterministic signal in the Claude Agent SDK to evaluate whether an agentic loop should continue executing tools or terminate?
- A . Parsing the assistant’s natural language text output for completion keywords like ‘task complete’.
- B . Inspecting the stop_reason field of the response for tool_use versus end_turn.
- C . Monitoring the total token count and exiting the loop when it reaches the context window limit.
- D . Setting a hard maximum iteration cap of 5 loops to prevent infinite execution.
To optimize a CI/CD pipeline, your manager wants to use the Message Batches API to reduce costs by 50%. The pipeline includes a real-time, blocking pre-merge code review, and a separate nightly technical debt audit.
How should you apply the Batch API?
- A . Use the Batch API for both workflows to maximize cost savings, utilizing status polling for the pre-merge check.
- B . Use synchronous API calls for both workflows, as the Batch API does not support structured JSON schema outputs.
- C . Use the Batch API strictly for the nightly technical debt audit, and retain synchronous real-time calls for the blocking pre-merge review.
- D . Switch both to the Batch API, but implement a timeout fallback that switches to synchronous calls if the batch exceeds 5 minutes.
