You are using Claude Code to accelerate software development. Your team uses it for code generation, refactoring, debugging, and documentation. You need to integrate it into your development workflow with custom slash commands, CLAUDE.md configurations, and understand when to use plan mode vs. direct execution.
You need to add a date validation check ensuring event dates are in the future. This requires adding a conditional statement to one existing function in a single file. What is the most appropriate approach?

• A. Enter plan mode first to create a detailed implementation strategy before making the change.
• B. Start with extended thinking mode enabled to ensure thorough reasoning about the validation logic.
• C. Use direct execution to make the change.
• D. Enter plan mode to analyze how the validation might impact other parts of the reservation flow.

A critical bug is affecting production users. Error logs show exceptions in the OrderProcessing module with a clear stack trace pointing to a specific function. You haven't worked with this module before. What's the most effective approach?

• A. Use plan mode to analyze the error in context of the module's design, enumerate potential root causes, and prioritize fixes systematically.
• B. Enter plan mode to explore the module's architecture and dependencies before attempting any fixes.
• C. Use direct execution to examine the stack trace, read the relevant code, and implement a fix once you identify the root cause.
• D. Start with direct execution to gather initial information, then switch to plan mode to design a comprehensive solution before implementing any changes.

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

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

Your MCP server implements a check_availability tool that queries an external calendar API.
During testing, you encounter three error conditions: (1) the tool is called with a malformed request missing the required user_email parameter, (2) the calendar API returns a 404 because the specified user doesn't exist in the calendar system, and (3) the calendar API returns a 503 because the service is temporarily unavailable. How should each error be reported according to MCP's error handling design?

• A. Report all three as JSON-RPC protocol errors.
• B. Report errors 1 and 2 as JSON-RPC protocol errors; report error 3 as a tool result with isError:
  true.
• C. Report all three as tool results with isError: true.
• D. Report error 1 as a JSON-RPC protocol error; report errors 2 and 3 as tool results with isError:
  true.

Production logs show that when the agent handles complex billing disputes requiring 6+ tool calls, it sometimes exhausts its max_turns limit after gathering data but before completing resolution or escalating. The team's goal is to guarantee that every customer interaction ends with either a completed resolution or a human handoff, regardless of how the agent loop terminates. Which approach achieves this guarantee?

• A. Implement a pre-tool-use hook that counts tool invocations and terminates the loop with an automatic escalation once the agent reaches 80% of its max_turns limit.
• B. Add orchestration-layer code that checks the agent's outcome after each loop termination - if the loop ended without a completed resolution or escalation, programmatically call escalate_to_human with the accumulated conversation context and tool results.
• C. Split the workflow into two sequential agent invocations - a first agent gathers information via get_customer and lookup_order, then a second agent receives that data and handles process_refund or escalate_to_human, each with separate turn budgets.
• D. Add system prompt instructions telling the agent to call escalate_to_human with a summary of its findings whenever it determines it cannot complete resolution within its remaining actions.
