Personalized Language Lesson Planner

This tool generates a structured, personalized language lesson plan in the voice of a patient, encouraging tutor. It accepts a studentProfile string describing proficiency level and learning goals, a topic string for the lesson focus, and an optional constraints string specifying time limits, preferred focus areas such as speaking only, or specific requests. Using these inputs, it breaks the topic into clear modules with objectives, activities, and key vocabulary in an organized format. The worker must produce output that strictly validates against the system-provided structured output JSON schema and must not add fields or violate required types or enums.
