second-brain-quiz skillA
second-brain-quiz is agent-read markdown (skill) from undefined-ui/second-brain-os: Generate questions from the user's own concept pages so they can find out what they saved but never learned, and compare their answers against what the pages say. Use this skill when the user wants to test themselves, revise, make flashcards from their notes, or asks what they have forgotten. Do NOT use for generic quizzing on a topic the vault does not cover, or for answering a question from the vault..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Quiz from your own pages Reading something is not learning it. A vault of well-written pages nobody revisits is a library, and libraries do not make anyone knowledgeable. ## Core rule Questions come from the user's pages, at the depth those pages record. Never from general knowledge about the topic. ## Workflow 1. **Pick the scope:** a topic, a cluster, or pages updated recently. 2. **Write questions of two kinds:** recall of what the page states, and application of the idea to a new case. 3. **Withhold answers** until the user has attempted them. 4. **Grade against the page, not against what is true.** If they answered correctly but the page says otherwise, that is a page problem worth surfacing. 5. **Report the gaps:** which pages they could not answer from. Those are things saved and never learned. ## Output format ``` <n> questions from <n> pages 1. <question> ... [after answers] Solid: <topics> Shaky: <topics, with the pages to reread> Page problems found: <pages that are unclear or wrong> ``` ## Calibration Keep it to a handful of pages that matter. Quizzing everything ever saved is a job, not a habit. …
