How do you access the input arguments (dictionary) requested by Claude within a tool use block in a response?	By chaining `response content[1].input`.
If a function requires keyword arguments (e.g., `date_format`), how do you pass a dictionary of arguments to it?	By using the double-star operator (`**`), e.g., `function_name(**dictionary)`.
What must the follow-up request to Claude include after a tool has been executed?	The full conversation history, including the original user message, the assistant message with the tool use block, and a new user message containing the tool results.
Where is the tool result block placed in the message history sent back to Claude?	Inside a user message.
What is the purpose of the `tool_use_id` in a tool result block?	To uniquely tie a specific tool result output back to the original tool use request, allowing Claude to match them correctly.
What are the essential properties within a tool result block?	`tool_use_id`, `content` (the result of the function), and optionally `is_error`.
How should the output of a tool function be formatted when placed in the tool result block?	It should be converted into a string, typically by converting it to plain JSON.
Describe the final step in the tool execution process after the tool result is sent back to Claude.	Claude processes the tool result and provides a final response, which usually contains a text block.
