What problem does it solve? Creating interactive study or exam apps for kids normally requires a build toolchain, hosting setup, and frontend work. This Skill turns a subject and grade level into one self-contained HTML file that runs offline by double-click or Netlify Drop, with gamification and progress tracking built in. ## Core Features & Use Cases - Single-file generation: All CSS and JS inline, zero dependencies, no CDN, no build step; Hebrew RTL by default with LTR support for other languages. - Gamified engine: XP, levels, milestone badges, streaks, localStorage persistence with continue-where-you-left-off, and optional Hebrew text-to-speech that degrades silently. - Four question types: Multiple choice, true/false, numeric with tolerance, and short fill-in, each with immediate feedback, explanations, and an answer-review screen. - Anti-fabrication safeguards: Uses supplied source material verbatim, flags AI-generated question sets with an on-screen review banner, and enforces answer-key consistency checks. - Use Case: A parent asks for a grade-8 chemistry practice app on atoms and molecules from the מטח textbook; the Skill fills the EXAM object in the template, validates the answer keys, and delivers a ready-to-deploy HTML file plus a hub card snippet. ## Quick Start Ask your assistant to create a grade-8 Hebrew math exam app on fractions and it will generate the single HTML file ready for Netlify Drop.
