What problem does it solve? It turns raw course transcripts, screenshots, and beginner questions about cybersecurity into clean, original Markdown study notes and book chapters in Brazilian Portuguese, without copying the instructor's speech or exposing sensitive lab data. ## Core Features & Use Cases - Transcript-to-chapter conversion: Cleans machine-translated transcripts, removes noise, and rewrites the lesson as an original narrative following the order the topic was learned. - Beginner-depth explanations: Defines jargon on first use, explains network components, ports, protocols, and data flow, and links to canonical notes instead of repeating explanations. - Interactive quiz generation: Creates 6-12 per-lesson quiz questions with four plausible alternatives, balanced answer lengths, and a mandatory validation checklist before publishing. - Screenshot sanitization: Selects only didactically relevant captures, redacts secrets and identifiers, and stores copies in an assets folder with relative links. - Use Case: After watching a Cloud-Based Hacking lesson, paste the transcript and screenshots; the Skill produces a publishable MkDocs chapter with sanitized images and a linked quiz. ## Quick Start Use the cyber-study-book skill to turn this lesson transcript into a study note chapter with a quiz.
