MCQs where the wrong answers are actually wrong for the right reasons.
Ask an LLM for multiple-choice questions and you tend to get a correct answer that's noticeably longer, more specific, or more "serious" sounding than the three distractors around it — guessable without knowing the subject at all. This skill is a set of writing rules that closes that gap: balanced option length, distractors that require real subject knowledge to eliminate, and a small script to check the result instead of just trusting it.
/plugin marketplace add Simooo45/quiz-generator
/plugin install quiz-generator@quiz-generator
Send these as two separate messages — the install only sees the marketplace once the first one has landed. Then just ask for what you want:
"Write 10 MCQs on photosynthesis for a high-school bio quiz"
and Claude reaches for the skill on its own — or invoke it directly with
/quiz-generator:quiz-generator. Prefer not to touch the plugin system at
all? Jump to manual install, it's one
cp.
The most common tell in a generated question bank: the correct option runs longer than the other three, because it's the one built from a real, dense fact and the distractors are filler. Once you know to check for that, it's an easy pattern to write around — but nobody writing a hundred questions by hand keeps it in mind on every single one. This skill keeps you honest: length and register balanced across all options, distractors that need subject knowledge (not tone or absurdity) to rule out, and a role-swap technique for the "these two are basically the same" trap, which is the hardest distractor shape to fake convincingly.
scripts/verify-quiz.mjs runs the length check for real, on a plain JSON
export of your question bank, zero dependencies:
node scripts/verify-quiz.mjs questions.json
Skills work the same whether they come from a plugin or sit directly in a skills folder:
git clone https://github.com/Simooo45/quiz-generator.git
cp -r quiz-generator ~/.claude/skills/quiz-generator # available in every project
# or
cp -r quiz-generator .claude/skills/quiz-generator # this project onlyInvoke it as /quiz-generator.
