NEW QUESTION # 99
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.
A user expands the research system beyond its original web-search agent by adding specialized data sources.
A financial API agent returns structured JSON containing revenue, margins, and growth rates. A news- monitoring agent returns prose summaries of recent developments. A patent-analysis agent returns structured lists of technology areas. The synthesis agent combines these results into executive briefings. Currently, it converts everything into bullet points, causing financial comparisons to lose tabular clarity and news summaries to lose their narrative flow.
What change would most improve briefing quality?
Answer: B
Explanation:
Option C preserves the information structure that makes each source useful. Financial metrics share comparable fields and therefore benefit from rows, columns, aligned units, and reporting periods. News findings require connected prose to preserve chronology and causal relationships, while patent technology areas are naturally represented as categorized lists. Anthropic's output-consistency guidance recommends specifying the exact output format needed for the task rather than relying on an unspecified default. Anthropic' s discussion of its multi-agent research system also recognizes specialized output stages for reports, structured data, and visualizations because specialist prompts can produce better results than generic coordinator processing. Option A destroys the comparative structure of numerical data. Option D can provide a useful provenance contract internally but does not determine how the executive briefing should present heterogeneous content. Option B risks creating a lowest-common-denominator representation that discards source-specific advantages. The synthesis contract should preserve normalized facts and provenance internally while directing the report generator to select presentation forms according to the content's semantic structure and the executive reader's needs.
NEW QUESTION # 100
During testing, when a customer says, "I need a refund for my recent purchase," the agent immediately invokes process_refund but populates the required order_id parameter with a plausible-looking fabricated value instead of first calling lookup_order. The refund fails because the invented order identifier does not exist. Which change directly addresses the root cause of the fabricated order_id?
Answer: C
Explanation:
Option A corrects the missing tool contract that permits Claude to guess a required parameter. The process_refund description should state its prerequisite explicitly: invoke lookup_order, use only the exact order_id returned by that successful call, and ask for additional identifying information when lookup cannot resolve an order. An input example can demonstrate the correct two-tool sequence.
Anthropic's tool-definition guidance identifies detailed descriptions as the most important factor in tool performance. Descriptions should explain when a tool should and should not be used, what every parameter means, and all important limitations. The tool-use overview confirms that Claude selects and populates tools based on the request and their descriptions.
Option B forces some tool call but does not tell Claude which tool must run first or where the identifier originates. Option C is an essential defence-in-depth control, but it detects the fabricated value after Claude has already made the incorrect decision. Option D works only when the customer supplies an identifier and does not cover "recent purchase." Explicit prerequisite and provenance instructions directly prevent the model from inventing the required argument.
NEW QUESTION # 101
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.
Your agent needs to insert a new helper function into the middle of a 150-line utility module, between two existing functions. The Edit tool fails because its old_string parameter cannot find unique text to match-the file has repetitive docstrings, variable names, and structural patterns.
What is the most reliable way to complete this insertion?
Answer: C
Explanation:
Option D is the closest match to Claude Code's documented editing procedure. The Claude Code tools reference explains that Edit performs exact string replacement and requires old_string to appear exactly once.
When the text occurs multiple times, the prescribed response is to include sufficient surrounding context to identify one occurrence uniquely. For this insertion, the match should span a distinctive boundary between the preceding function and the following function. It does not literally need 30 lines; it needs the smallest exact block that is demonstrably unique, but option D is the only answer expressing that method.
Option A would modify every occurrence of a repeated pattern and could insert the helper function multiple times. Option B places the function at the end rather than at the required architectural location. Option C can technically work, but Write replaces the complete file and increases the change surface. Anthropic explicitly states that Write creates or overwrites full files, while partial modifications should use Edit. A targeted, uniquely anchored Edit preserves all unrelated content and produces a smaller, safer diff.
NEW QUESTION # 102
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.
Engineers frequently ask the agent to cross-reference code changes with Jira tickets during reviews- checking ticket descriptions, acceptance criteria, and recent comments. This currently requires manually copying and pasting content into conversations. The team wants the agent to access this standard Jira ticket data directly.
What is the most effective approach?
Answer: D
Explanation:
Option D uses the established integration mechanism without creating unnecessary infrastructure. Anthropic's Claude Code MCP documentation specifically recommends connecting an MCP server when users repeatedly copy information from an external system, such as an issue tracker, into conversations. Once connected, the server exposes Jira operations through named, schema-defined tools that Claude can discover and invoke directly. This allows the agent to retrieve ticket descriptions, acceptance criteria, comments, and metadata while preserving the server's authentication and access controls.
Option A exposes authentication details to shell commands and requires the agent to construct requests and parse responses repeatedly. Option B is justified only when no existing server provides the required capabilities or the workflow requires highly specialized operations. The question requires standard Jira information, so building and maintaining another server is unnecessary. Option C creates stale, manually synchronized copies that lose permissions, current comments, and authoritative ticket state. The team should therefore select a trusted Jira MCP implementation, configure appropriate read-only scopes where possible, and verify its tool descriptions and data-access boundaries before enabling it.
NEW QUESTION # 103
A chatbot frequently receives greetings, policy questions, and technical support requests. Which architecture improves maintainability?
Answer: C
Explanation:
Prompt routing directs requests to specialized workflows optimized for different tasks. Separate prompts and tools improve accuracy, simplify maintenance, and reduce conflicts between unrelated instructions.
