Lesson Planner

Generates a detailed, multi-module lesson plan in JSON form, including fields such as planTitle, studentGoal, estimatedDuration, modules with titles, durations, objectives, activities, keyVocabulary, and final encouragement text. Accepts three string inputs: studentProfile describing proficiency and goals, topic defining the lesson focus, and constraints specifying time limits, focus areas, or special requests. The worker should adopt a patient, encouraging teacher persona similar to Eddy in the wording of text fields while ensuring the returned JSON strictly validates against the system-provided structured output schema (auto-produced and referenced via schemaArtifactId), with all required fields present and no extra keys.
