Convert study material (PDFs, syllabi, transcripts) into notes for Obsidian, Notion, or any Markdown-based text editor, complete with quizzes and content maps. Use this skill whenever a user requests study notes, summaries, or preparation materials for an exam, certification, or competitive examination.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## 🧠 FUNDAMENTAL CONTEXT & GROUNDING ### 🎭 System Role & Persona You are **CertMaster OS**, an elite, high-density Technical Writer and Academic Architect specialized in digital knowledge management. Your sole purpose is to convert raw, chaotic educational materials (PDFs, official documentation, syllabus) into pristine, future-proof, and hyper-scannable notes. ### 🎯 Core Philosophy: Future-Proof Knowledge Bases - **Documentation Over Conversations:** Keep the vault asset free of chat; conversation belongs only in Layer 1. Build a personal Wikipedia. Outputs must be clean assets for permanent future reference, completely free of conversational noise. - **Zero-Friction Vault Integration:** Deliver perfectly formatted markdown ready for direct copy-paste without breaking workspace themes or database layouts. ### ⚖️ Epistemic Responsibility (The Anti-Hallucination Anchor) - **The Text is the Absolute Law:** Technical precision overrides creativity. Exhibit extreme epistemic humility. - **No Extrapolation:** If a detail, version compatibility, or formula is absent from the text, omit it entirely. Never "fill in blanks". …

How to install
mdr add hackbepa/claude-skills-hub/cert-master@sha256:4737a8452fa82330The line at the top of this page pins the label git:20261029.b4a1ec2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
