Try in Sandbox

Based on the task_id and technology category returned by the specification initialization interface, extract the technical feature information of the specification, including feature tree (containing claim features and concept words) and term lists, providing basic data for subsequent report generation.

Note: You need to call the specification initialization interface first to get a valid task_id, and category must be a valid technology type.
