20+ practice questions focused on Agents and the Agent SDK — one of the most tested topics on the Claude Certified Developer exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Agents and the Agent SDK PracticeRefer to the exhibit. An agent is consistently failing to use the provided tool. What is the most likely cause based on the provided JSON definition?
Explanation: The JSON schema lacks a 'required' field for the 'query' property. While optional properties are valid, many LLMs struggle to infer whether they should invoke a tool if the input schema is ambiguous or lacks explicit requirements. Including the 'required' array ensures the model understands that the 'query' parameter is mandatory for successful tool execution, improving reliability in agentic workflows.
When using the 'tool_use' capability in the Anthropic SDK, what is the significance of the 'stop_sequences' parameter?
Explanation: The 'stop_sequences' parameter provides a way to explicitly instruct the model to stop generating text when a specific sequence is encountered. In agentic loops, this is useful for preventing the model from continuing to 'reason' after it has decided to invoke a tool. This ensures the output can be parsed as a valid tool-use block immediately, improving the efficiency of the orchestration loop.
A developer is building an agent that must coordinate between three different specialized tools. During testing, the agent occasionally enters a loop where it calls the same tool repeatedly with identical arguments. Which architectural pattern within the Agent SDK is most effective for preventing this behavior while maintaining autonomous reasoning?
Explanation: Implementing state-aware monitoring and iteration limits is essential for robust agent design. By tracking tool execution history within the agent's memory, developers can detect redundant patterns before they consume excessive tokens. This approach ensures the agent remains cost-effective and prevents infinite recursion in complex reasoning loops where the model fails to progress towards a final answer effectively.
Which TWO of the following are primary benefits of using the Model Context Protocol (MCP) when building agents with the Anthropic SDK?
Explanation: MCP standardizes how agents interact with external data sources and tools, reducing the need for custom integration code for every new service. By decoupling the tool implementation from the agent logic, developers can create more modular and reusable components that can be shared across different projects, enhancing the scalability of complex agentic ecosystems.
A team is building a customer-support agent on the Anthropic SDK. They define three tools with clear descriptions and valid input schemas, yet the agent sometimes answers from memory instead of calling search_knowledge_base, and occasionally invents a tool name that was never registered. The team wants to make tool invocation more reliable. (Choose two.)
Explanation: Reliable tool use comes from constraining the model toward tool calls and making each tool's purpose unambiguous. Forcing a tool call with a tool_choice setting of any prevents memory-based answers, while precise descriptions and schemas ensure the model picks the registered tool whose semantics actually match the request. Together these reduce both skipped calls and invented tool names.
