NEW QUESTION # 136
When implementing your lookup_order MCP tool, the backend sometimes returns errors-for example,
"Order not found" or temporary database failures. What is the correct pattern for communicating these errors back to the agent?
Answer: A
Explanation:
Option A follows the MCP error contract. An error originating during execution of a valid tool call-such as an API failure, input-validation problem, or business-logic failure-should be returned inside the tool result with isError: true. The content should explain what happened and, where possible, provide actionable recovery guidance.
The official MCP tools specification distinguishes tool-execution errors from protocol-level errors and specifies that execution failures are reported through tool results using isError: true. Anthropic's tool-using agent tutorial provides the equivalent Claude API pattern using is_error: true, allowing Claude to retry with corrected input, request clarification, or explain the limitation.
Option B falsely represents a failed operation as successful, weakening reliable failure detection. Option C deprives the agent of the information required to determine an appropriate recovery action. Option D may be converted into a tool error by some SDK runners, but uncaught exceptions are not the MCP-level response contract. The strongest implementation returns a concise, sanitized, actionable error result and separately records detailed diagnostics in server logs.
NEW QUESTION # 137
A developer wants Claude to explain every reasoning step internally before answering. Why might this request be inappropriate?
Answer: B
Explanation:
Applications should evaluate Claude based on observable outputs rather than expecting access to internal reasoning processes. Prompting should request useful explanations or evidence instead of relying on hidden reasoning mechanisms.
NEW QUESTION # 138
You are building a structured data extraction system using Claude. The system extracts information from unstructured documents, validates the output using JSON schemas, and maintains high accuracy. It must handle edge cases gracefully and integrate with downstream systems.
Your extraction uses tool use with a JSON schema in which property_type is defined as an enum: house, apartment, condo, or townhouse. After deployment, 8% of extractions fail schema validation. Investigation reveals that listings mention many uncommon property types-"studio," "loft," "duplex," "mobile home,"
"tiny house," and "converted warehouse"-and new types continue appearing regularly.
What is the most effective long-term solution?
Answer: D
Explanation:
Option A is the most sustainable open-world design. The property-type domain is demonstrably not closed:
uncommon values already occur, and new labels continue to appear. An enum is appropriate only when the valid vocabulary is stable and exhaustive. If the source contains a legitimate value outside that vocabulary, the schema either rejects it or pressures the model to map it inaccurately. A free-form string preserves the source meaning, while deterministic post-processing can normalize "studio," "loft," "duplex," and future terms into an evolving canonical taxonomy. Anthropic's Structured Outputs documentation distinguishes structural schema conformance from the semantic decisions made within that schema; it also documents that JSON Schema constraints such as enums govern allowable output shapes and values. Few-shot mapping to the nearest existing enum, option B, discards real distinctions. Continually expanding the enum, option C, creates recurring schema changes and still lags newly observed values. An "other" bucket with detail, option D, is workable but collapses all emerging categories at the primary field and complicates analytics until downstream interpretation occurs. Capturing the raw type first and normalizing it in code provides lossless extraction, testable mappings, and forward compatibility.
NEW QUESTION # 139
Your control_device tool manages smart home devices through external APIs. When a device doesn't respond within the timeout period, the tool returns an error. Production logs show that the agent simply tells users "the device is not responding" without offering helpful next steps. Which error response structure would best enable the agent to provide useful follow-up?
Answer: A
Explanation:
Including the likely cause and actionable troubleshooting steps in the error response allows the agent to communicate helpful guidance to the user, rather than just reporting the failure. This improves user experience and supports effective problem resolution.
NEW QUESTION # 140
You are building developer productivity tools using the Claude Agent SDK. The agent helps engineers explore unfamiliar codebases, understand legacy systems, generate boilerplate code, and automate repetitive tasks. It uses the built-in tools (Read, Write, Bash, Grep, Glob) and integrates with Model Context Protocol (MCP) servers.
An engineer sees an unfamiliar error message "SYNC_CONFLICT: entity version mismatch detected" in production logs but doesn't know which of the 12 services in the codebase generates it. They ask the agent to help locate the source code. What exploration approach will most efficiently find the responsible code?
Answer: D
Explanation:
Searching for the exact error code or unique message fragment is the fastest way to locate where it is defined or emitted. Read can then inspect the surrounding implementation and call path.
