What problem does it solve? Bilingual education sites must keep every English lesson and its Spanish twin in perfect parity — same slugs, order, headings, and interactive component labels — which is tedious and error-prone to maintain by hand. ## Core Features & Use Cases - Locale-aware translation: Produces peninsular Spanish (es-ES, Castilian) with vosotros register and Spain-specific vocabulary, never Latin-American variants. - Structural parity enforcement: Keeps frontmatter fields (order, minutes, icon, accent), heading hierarchy, imports, code blocks, and client directives identical across the en/es pair. - Component label localization: Translates interactive island props (MCQ, Quiz, MatchConcepts, FillBlank, MindMap labels) so UI chrome renders in Spanish. - Use Case: After authoring a new English lesson on mental models, run this Skill to generate the mirrored es-ES MDX file, then verify parity with bun run check and regenerate OG cards. ## Quick Start Translate the English lesson at src/content/lessons/en/biases/anchoring.mdx into its Spanish twin and keep all frontmatter and component labels in parity.
