What problem does it solve? Creating a new lesson for this bilingual education site requires coordinating many moving parts: correct MDX frontmatter, mirrored English and Spanish files, interactive exercise components, difficulty tiers, dependency wiring, and OG image regeneration. This Skill turns that multi-step authoring process into a single guided workflow. ## Core Features & Use Cases - Bilingual scaffolding: Creates the English MDX file and its peninsular-Spanish twin in the correct locale folders with valid frontmatter (title, description, topic, order, difficulty, dependencies). - Interactive component wiring: Integrates the reusable React islands (MCQ, Quiz, FinalExam, FillBlank, MatchConcepts, Categorize, MindMap) with proper client directives and localized Spanish label props. - Pedagogical structure enforcement: Requires pretest questions per section, at least one teaching animation, spaced-recall exercises, and a mandatory FinalExam lesson closing every topic. - Use Case: Ask to "add a lesson about anchoring bias" and the Skill researches the topic, writes witty analogy-driven copy in both languages, embeds exercises and animations, runs validation checks, and regenerates OG share images. ## Quick Start Ask the assistant to create a new lesson about a specific subject, for example: add a beginner lesson about loss aversion to the mental models site.
