Implementation Reference
- src/index.ts:381-460 (handler)The handler function for the 'get-a-subject-with-detail' tool. It takes enrollment_grade and freeword parameters, fetches matching subjects from the ZEN University syllabus API using fetchAllPages, filters and formats the data, and returns a text response with a list of subjects and detailed info for the first one.
