NEW QUESTION # 44
Your content curation agent discovers articles, analyzes each for relevance, then adds selected articles to themed collections. With separate discover_articles(topic), analyze_article(id), and add_to_collection(article_id, collection_id) tools, you observe 18+ sequential tool calls per request, causing latency issues. The agent must make editorial judgments about which articles fit a collection's theme - this requires seeing all candidates with their analysis scores simultaneously to select a cohesive set. What tool composition best addresses efficiency while preserving editorial judgment?
Answer: D
Explanation:
Combining discovery and analysis into a single tool call returns all candidate articles with their scores at once, allowing the agent to make informed editorial decisions efficiently. Keeping the collection addition separate preserves selective control while reducing sequential calls and latency.
NEW QUESTION # 45
The coordinator agent has AgentDefinition objects configured for all four specialized subagents, each with appropriate descriptions, prompts, and tool restrictions. During testing, you notice that the coordinator correctly reasons about when to delegate-it generates messages such as, "I'll ask the web-search agent to find sources on this topic"-but no subagent execution occurs. The coordinator then proceeds as if the delegation happened and continues with incomplete information. Logs show no errors. What is the most likely cause?
Answer: B
Explanation:
Option B identifies the missing executable capability. Defining specialized agents makes their configurations available, but the coordinator must still be permitted to call the tool that invokes them. Without that tool, Claude can describe an intended delegation in ordinary text but cannot create a subagent execution.
The current Claude Agent SDK documentation requires " Agent " in allowedTools to auto-approve subagent invocations. The tool was renamed from " Task " to " Agent " in Claude Code 2.1.63, so the terminology in the original candidate question required correction. Older integrations may still expose " Task " in initialization or permission records.
Option A is unlikely because properly written AgentDefinition.description values already tell Claude when each agent should be used. Option C misinterprets context isolation: the parent supplies the subagent's assignment through the Agent tool's prompt, and no additional automatic forwarding setting is required.
Option D would normally produce truncation evidence or a max_tokens stop reason rather than silent absence of every invocation. The coordinator needs both agent definitions and permission to use the invocation tool.
NEW QUESTION # 46
You are building a structured data extraction system using Claude. The system extracts information from unstructured documents, validates the output using JavaScript Object Notation (JSON) schemas, and maintains high accuracy. It must handle edge cases gracefully and integrate with downstream systems.
Your system extracts event metadata (date, location, organizer, attendee_count) from news articles using a JSON schema with all nullable fields. During evaluation, you observe the model frequently generates plausible but incorrect values for fields not mentioned in the article--for example, outputting "500" for attendee_count when the source contains no attendance information.
What's the most effective way to reduce these false extractions?
Answer: C
Explanation:
The schema already supports the correct representation of missing evidence: null. The remaining defect is behavioral. Claude must be explicitly instructed that absence of information is a valid outcome and that values may be populated only when directly supported by the supplied article.
Anthropic's hallucination-reduction guidance recommends explicitly permitting Claude to express uncertainty, grounding outputs in the source, and retracting claims that lack supporting evidence.
It also recommends restricting the model to the provided documents rather than allowing unsupported external knowledge. Option C translates those controls directly into the extraction contract: when no source evidence exists, the model returns null.
NEW QUESTION # 47
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, and Glob-and integrates with Model Context Protocol (MCP) servers.
An engineer asks the agent to find every file in a monorepo that imports the @company/auth package to understand how authentication is used across services.
Which built-in tool is most appropriate for this task?
Answer: A
Explanation:
Option C directly searches source-file contents for imports of @company/auth . Anthropic's Claude Code tools reference states that Grep locates patterns within files, while Glob matches filenames and paths. The search can account for the repository's supported module syntaxes, including static imports, require() calls, dynamic imports, and re-exports. It can also restrict results by file type or directory when appropriate. Option A identifies packages that declare the dependency but does not prove which source files import or invoke it; workspace-level dependency declarations may cover many packages. Option B finds authentication-related filenames, which are unrelated to whether a file imports the package. Option D searches directory names and therefore has the same limitation. After Grep returns the matching files and line numbers, the agent can read the surrounding code to determine whether each import supports middleware registration, token verification, authorization checks, or re-exporting. This produces an accurate usage inventory while minimizing context consumption and unnecessary file reads.

Answer: D
Explanation:
Grep searches file contents across the repository, making it the correct tool for locating every source file that imports @company/auth. Glob searches filenames and paths, not code content.
