What is the primary downside of using tools for structured data extraction?	Having to write and manage large JSON schemas.
What is the "trick" proposed to alleviate the pain of managing large JSON schemas?	Using a single, flexible schema (e.g., `to_json`) that accepts an object with as many properties as Claude wants to add.
When using the flexible schema trick, where is the actual desired data structure (properties and types) defined?	Inside the prompt.
How is the flexible schema trick executed?	By telling Claude to call the tool and pass arguments that follow the structure listed in the prompt.
What is a key advantage of defining the data structure within the prompt?	It allows for easy modification of the required data structure by making a simple edit to the prompt.
What is the main limitation of using the flexible schema method?	The results may not be as good as a dedicated schema, especially at extreme levels.
When should a user choose a dedicated, hard-coded schema over the flexible prompt method?	When performing a very critical data extraction task.
