In an automated code review workflow, why is it considered a major architectural anti-pattern to have the same Claude session both generate code and subsequently review its own generated changes?

• A.It exceeds the maximum token limits for the context window during the generation phase.
• B.The reviewer retains the reasoning context and assumptions from the generation phase, creating confirmation bias.
• C.The Message Batches API does not support multi-turn tool calling within a single request.
• D.Tools invoked during the first pass are permanently locked and cannot be reused in the review pass.

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.
A developer asks the agent to investigate why a specific API endpoint intermittently returns 500 errors. The codebase has 200+ files and the developer doesn't know which components are involved. The agent must trace the error through routing, middleware, business logic, and database layers. What task decomposition approach would be most effective?

• A.Have the agent dynamically generate investigation subtasks based on what it discovers at each step, adapting its exploration plan as new information about the error path emerges.
• B.Have the agent first create a comprehensive plan mapping all code paths through the endpoint before beginning any file exploration or code reading.
• C.Run parallel worker agents that simultaneously investigate all four layers, then synthesize their findings to identify where the error originates.
• D.Define a fixed sequence of investigation steps upfront - grep for error patterns, then read error handlers, then check database queries, then examine middleware - executing each step regardless of intermediate findings.

After updating a tool description to perfectly define its purpose and boundaries, Claude still occasionally misroutes specific requests to an older, less appropriate tool. What hidden factor is most likely causing this unintended tool association?

• A.The tool_choice parameter is set to auto instead of any.
• B.Keyword-sensitive instructions embedded in the system prompt are overriding the tool descriptions.
• C.The Model Context Protocol automatically defaults to tools with shorter alphabetical names.
• D.The agent is executing a PostToolUse hook that rewrites the tool execution payload.

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?

• A.Set is_error: true with a structured technical error containing the device ID, timeout duration, and raw API response code for debugging purposes.
• B.Set is_error: true with a brief "Device offline" message and provide a separate tool the agent can call to retrieve context-specific troubleshooting suggestions.
• C.Set is_error: false with an optimistic message indicating the command was dispatched successfully but device acknowledgment is still pending.
• D.Set is_error: true with a message explaining the likely cause and suggesting troubleshooting steps the agent can offer the user.
