What problem does it solve? Learning a new topic with an AI assistant is usually stateless: every session starts from zero, prior knowledge gets re-taught, and there is no record of progress. This Skill turns a directory into a persistent teaching workspace that tracks the learner's mission, knowledge, and progress across sessions. ## Core Features & Use Cases - Stateful Learning Workspace: Maintains MISSION.md, RESOURCES.md, GLOSSARY.md, NOTES.md, and numbered learning records to capture what the user knows and why they are learning. - HTML Lesson Generation: Produces self-contained, beautifully typeset lessons in ./lessons/ with quizzes, citations to trusted sources, and links to reusable reference documents. - Zone of Proximal Development: Reads learning records to pick the next topic that challenges the learner just enough, applying retrieval practice, spacing, and interleaving. - Use Case: A user wants to learn strength training over several weeks. The Skill interviews them to write a mission, curates trusted resources, generates short interactive HTML lessons, and records each demonstrated understanding so future sessions build on it. ## Quick Start Ask the assistant to teach you a topic, for example: teach me the basics of SQL indexing over the next few sessions.
