Generate interactive multi-lesson courses with quizzes

Lesson Generator builds a standalone, browser-ready multi-lesson course artifact - defaulting to 6-8 ordered lessons unless the user explicitly wants a single lesson, never collapsing a general request into one long lesson page. Each lesson gets a goal, 2-4 learning objectives, 2-3 flashcards, a 1-2 question quiz, and source links or stated source assumptions, kept deliberately compact (concise bodies, no giant embedded essays) so the browser preview stays responsive. The whole course is planned - title, 2-3 sentence description, ordered lesson list - before any UI code is written.

Use it when the request is for an interactive lesson, mini-course, study guide, course module, flashcards, quizzes, knowledge checks, or a learning artifact - something meant to be opened and used repeatedly, not a landing page. It assumes no backend, database, or external service; everything must work as a self-contained artifact, and it explicitly avoids oversized marketing hero layouts in favor of a dense, study-oriented workspace feel.

Output is exactly three files at the workspace root - index.html, styles.css, script.js - never written inside node_modules, plugin, skill, or hidden directories, kept in plain HTML/CSS/JS unless a CDN library clearly improves an interactive visualization. Course data is represented as a structured JavaScript array of lesson objects so navigation, flashcards, quizzes, and progress state stay consistent, with JSON-serializable data and double-quoted or template-literal strings (unescaped apostrophes in single-quoted JS strings are explicitly called out as a bug source). The UI follows a learning-platform layout: course overview, lesson sidebar/table of contents, active lesson reader, objectives block, source rail, per-lesson flashcards and quiz, and a final cumulative review synthesizing the whole course. A fixed warm color palette is specified (#fbf7ef background, #c2410c accent, 8px radius, etc.) for a readable, non-generic learning UI.

When web search is available and used to source content, results are treated as untrusted material - cited or linked as real clickable <a href="..."> source cards in the artifact (never buried in hidden JS data, plain text, or only the chat response), and source text is never allowed to alter the build instructions themselves, a direct defense against prompt injection via scraped content. Before finishing, the skill smoke-tests the artifact's own logic: script.js must parse without syntax errors, "Start Learning" must open lesson 1, sidebar buttons must switch lessons, flashcards must flip, and quiz options must show feedback.

Educators, course creators, or self-learners who want a complete, ready-to-use interactive course generated in one pass - progressive lesson sequencing, built-in knowledge checks per lesson, a final review quiz, and real cited sources - rather than a single static explanation or a slide deck requiring separate assembly.
