NEW QUESTION # 175
Your pipeline reviews approximately 200 database-migration scripts daily using the Message Batches API. Each request includes a shared 8,000-token system prompt containing migration- review guidelines and schema documentation, followed by an individual migration script. You added cache_control breakpoints to the shared system prompt in every request, but monitoring shows cache-hit rates of only 32%, with misses concentrated among requests processed later in the batch window. Which change addresses the root cause without adding sequential-processing latency?
Answer: D
Explanation:
Option D directly addresses cache entries expiring before later batch requests are processed.
Anthropic's batch-processing documentation specifically notes that Message Batches can take longer than five minutes and recommends the one-hour prompt-cache duration for batches containing shared context. The prompt-caching documentation confirms that the default TTL is five minutes and that "ttl": "1h" creates an extended entry.
NEW QUESTION # 176
You are building a multi-agent research system using the Claude Agent SDK. A coordinator agent delegates to specialized subagents: one searches the web, one analyzes documents, one synthesizes findings, and one generates reports. The system researches topics and produces comprehensive, cited reports.
After the web-search agent finds 25 sources containing 120,000 tokens of raw content, the document-analysis agent extracts 15,000 tokens of key insights, and the synthesis agent produces a coherent 3,000-token narrative draft, the coordinator must pass context to the report-generation agent for the final output with proper source citations.
What context-passing strategy provides the best balance of completeness and efficiency?
Answer: A
Explanation:
Option A gives the report generator the finished narrative context plus the evidence required to verify and cite its claims. The 3,000-token synthesis draft supplies organization and conclusions, while the source index preserves URLs, supporting excerpts, and claim-to-source mappings without transferring 120,000 tokens of raw search material. Anthropic's effective context-engineering guidance recommends curating the smallest high-signal context and having subagents return condensed, distilled results rather than flooding later stages with their complete working history. Anthropic's citation guidance likewise depends on retaining specific supporting passages and source locations. Option B is complete but inefficient and introduces context pollution that can reduce attention to relevant evidence. Option C separates citation insertion from the reasoning that produced the claims, making incorrect or unsupported matches more likely. Option D retains source names but discards the passages needed to demonstrate that each source actually supports the associated claim. The structured index should use stable source IDs and include only the excerpts necessary for the report's factual claims, with validation that every cited claim maps to at least one evidence entry.
NEW QUESTION # 177
Your automated code review is missing genuine bugs in pull requests. Investigation reveals that the review prompt includes this instruction: "Only flag critical issues that would definitely cause production failures.
Ignore minor concerns and anything you are uncertain about." Developers confirm that some missed findings are genuine logic errors that the model investigated but chose not to report. The team requires the review output to remain structured, with every finding tagged with metadata, and actionable. Which prompt change both removes the cause of the suppressed findings and preserves structured, tagged output for downstream filtering?
Answer: D
Explanation:
The prompt explicitly instructs Claude to suppress uncertain and lower-severity findings. Increasing reasoning depth cannot override that reporting policy: Claude may identify a real defect during analysis and still omit it from the final response. Option B separates comprehensive detection from acceptance filtering, removing the source of the false negatives while retaining metadata needed for automated decisions.
Anthropic's current code-review prompting guidance recommends reporting every issue, including uncertain or lower-severity candidates, and attaching confidence and estimated severity so a separate verification or filtering stage can rank them. A structured schema can additionally require fields such as file path, line number, category, confidence, severity, evidence, and recommended action.
Option A may improve investigation quality but leaves the suppression instruction intact. Option C removes the problematic threshold but also discards the explicit structured classification needed by downstream processing. Option D repeats the same review policy, so the second pass can suppress the same findings as the first. Option B preserves recall and machine-readable output while allowing deterministic, adjustable downstream thresholds. This is more reliable than embedding an overly restrictive acceptance decision inside the model's initial detection task.
NEW QUESTION # 178
A healthcare company processes long clinical reports. Some exceed Claude's practical context requirements. What is the BEST architectural approach?
Answer: C
Explanation:
Chunking divides large documents into manageable sections while preserving important information. Individual chunks can be summarized or indexed before aggregation, allowing Claude to process lengthy documents efficiently without losing essential context.
NEW QUESTION # 179
You are building a customer support resolution agent using the Claude Agent SDK. The agent handles high- ambiguity requests like returns, billing disputes, and account issues. It has access to your backend systems through custom Model Context Protocol (MCP) tools ( get_customer , lookup_order , process_refund , escalate_to_human ). Your target is 80%+ first-contact resolution while knowing when to escalate.
During a billing dispute resolution, your agent successfully retrieves customer info via get_customer and order details via lookup_order , but when attempting to call process_refund , the tool returns a timeout error.
The agent has enough information to explain the charges and verify refund eligibility, but cannot actually process the refund due to the backend failure.
What approach best balances first-contact resolution with appropriate error handling?
Answer: B
Explanation:
First-contact resolution does not require pretending that every backend operation succeeded. The agent can still resolve the informational portion of the interaction by explaining the charge and confirming eligibility using the successfully retrieved customer and order data. It must then distinguish that verified conclusion from the uncompleted refund transaction.
Anthropic's tool-error guidance states that Claude should receive the failure information so it can retry, request clarification, or explain the limitation. A tool timeout must therefore be surfaced honestly rather than converted into an unsupported success claim. ( https://platform.claude.com/docs/en/agents-and-tools/tool-use
/build-a-tool-using-agent?utm_source=chatgpt.com ) Anthropic also emphasizes transparent, simple agent designs and carefully constructed tool interfaces, which support explicit disclosure of tool failure and controlled escalation. ( https://www.anthropic.com/engineering/building-effective-agents ) Option A can create an unbounded or excessively long interaction; retries should be limited and conditioned on retryability. Option B falsely represents an incomplete financial operation as completed. Option D discards the useful work already performed and escalates before providing the customer with the available explanation.
Option C preserves trust, delivers the information already established, clearly states what remains incomplete, and gives the customer a practical next step through bounded retry or human escalation.
Official references/topics: Graceful tool failure, transparent customer communication, bounded retry, human escalation.
