Fine to try.
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.
What this skill can do
We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.
Install
Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'second-brain-quiz' ] || [ -L ~/.agents/skills/'second-brain-quiz' ]; then echo 'A skill folder named second-brain-quiz already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/undefined-ui/second-brain-os' "$d" && git -C "$d" checkout --quiet '53aea8231aff3024352e21839dc08668f7ecc0b9' -- 'skills/second-brain-quiz' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/second-brain-quiz' ~/.agents/skills/'second-brain-quiz' && rm -rf "$d"; fi
Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'second-brain-quiz' ~/.claude/skills/'second-brain-quiz' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
