What `stop_reason` value indicates that Claude wants to use a tool?	`tool_use`
What is the primary goal of the `run conversation` function?	To repeatedly call Claude until it no longer requests tool usage.
What is the purpose of the `run tools` function?	To execute all tool use blocks within a single assistant message and return the results.
What is the first step inside the `run tools` function when processing an assistant message?	Filtering the message content to extract only the tool use blocks (tool requests).
What are the essential properties of a `tool result block`?	`tool_use_id`, `content`, and `type` (set to `tool_results`).
Why is it critical that the `tool_use_id` in a tool result block matches the ID in the original tool use block?	To correctly link the tool output back to Claude's specific request.
What is the purpose of the new helper function, `run tool`?	To centralize tool execution by taking a tool name and its input.
How does the `run tool` function determine which specific tool to execute?	By performing a series of if statements or checks against the provided tool name.
How was the original tool calling logic refactored to use the new `run tool` function?	Direct tool calls were replaced with `run tool(tool_request.name, tool_request.input)`.
What action does the `run tools` function take with the tool results?	It adds the tool results to the conversation history.
What condition determines when the `run conversation` function stops repeating the process?	When Claude no longer asks for tool use.
What critical coding requirement was highlighted when Claude made multiple tool calls in one message?	The code must correctly handle multiple tool use blocks within a single message.
What is the final step required for the project's tool support?	Adding support for the `add duration to date time` and `set reminder` tools.
