A quicktechie.com developer is designing a schema to extract contract terms. Source documents sometimes lack a 'termination_fee' clause. How should the schema be designed to prevent the model from fabricating a value?

• A.Add a capitalized warning in the system prompt to avoid hallucination.
• B.Design the field as strictly required and let the model infer a standard default.
• C.Design the field as optional or nullable, such as ["number", "null"].
• D.Set tool_choice. :"auto" so the model can skip the tool entirely.

When implementing an agentic loop using the Claude API, what is the only architecturally reliable signal to determine whether the loop should terminate or continue executing?

• A.Parsing the assistant's natural language text output for completion keywords like 'task complete'.
• B.Inspecting the stop_reason field of the API response for tool_use versus end_turn.
• C.Implementing a hard maximum iteration cap of 5 loops to prevent infinite execution.
• D.Monitoring the total token count and exiting when it reaches the context window limit.

When planning complex multi-flle architectural changes, such as a monolith-to-microservices migration, why is it recommended to use plan mode rather than direct execution?

• A.Plan mode automatically generates missing unit tests for legacy code before executing.
• B.Plan mode utilizes the Message Batches API to reduce token costs by 50 percent.
• C.Plan mode restricts Claude to using only read-only tools to explore the codebase, design a strategy, and get developer approval before making costly modifications.
• D.Plan mode overrides the token limit context window by executing across multiple continuous sessions automatically.
