Your agent uses three tools: get_property_details(property_id) returns data including street address, get_price_history(property_id) returns historical pricing, and get_neighborhood_info(address) returns area statistics. You observe that get_neighborhood_info always requires get_property_details first just to extract the address, even when users specify the property by ID. This creates unnecessary latency and failure coupling - if the first call fails, the neighborhood request also fails. What tool design change best addresses this?

• A. Create a lookup_address(property_id) helper tool for retrieving addresses.
• B. Add retry logic and timeout handling to get_property_details.
• C. Consolidate into a single get_property_with_neighborhood(property_id) tool returning both datasets.
• D. Change get_neighborhood_info to accept property_id, resolving the address internally.

An application frequently repeats the same background instructions in every API request. What is a potential downside?

• A. Reduced model capability.
• B. Higher token usage and cost.
• C. Increased hallucinations only.
• D. Lower reliability.

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.
Your agent has analyzed a complex service module -reading 23 source files, tracing request flows, and identifying error handling patterns. A developer wants to compare two testing strategies before committing to one: end-to-end tests with mocked external services vs. snapshot tests capturing expected outputs. They need to independently develop both approaches to evaluate trade-offs. How should you manage the sessions?

• A. Resume the analysis session with fork_session enabled, creating a separate branch for each testing strategy.
• B. Continue in the original session, developing end-to-end tests first, then snapshot tests sequentially.
• C. Start two fresh sessions, having each re-read the relevant source files before beginning.
• D. Export the analysis session's key findings to a file, then create two new sessions that reference this file.

A customer raises three separate issues during one session: a refund inquiry (turns 1-15), a subscription question (turns 16-30), and a payment method update (turns 31-45). At turn 48, the customer asks "What happened with my refund?" The conversation is approaching context limits.
What strategy best maintains the agent's ability to address all issues throughout the session?

• A. Summarize earlier turns into a narrative description, preserving full message history only for the active issue.
• B. Implement sliding window context that retains the most recent 30 turns.
• C. Rely on MCP tools to re-fetch relevant information on demand when the customer references earlier issues.
• D. Extract and persist structured issue data (order IDs, amounts, statuses) into a separate context layer.

An organization wants predictable outputs for automated invoice classification. Which API parameter should generally be LOWER?

• A. Temperature
• B. Context window
• C. Prompt length
• D. Max tokens
