At a glance
Quizzes you on the notes in an Obsidian StudyVault, tracks proficiency per concept and drills weak areas in four-question rounds.
- Works in 7 steps: Detect Language → Discover Vault → Ask Session Type → …
- Taking a diagnostic of what you know across a StudyVault
- SKILL.md covers File Structure, Workflow, Dashboard Template and Concept File Template, plus 1 more section
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
The agent finds the StudyVault in your project, reads its compact dashboard and asks what kind of session you want, offering options based on the dashboard: a diagnostic for unmeasured areas, drilling named weak areas, choosing a section, or a hard-mode review once everything is strong. It answers in your language and stops if no vault exists.
Each round builds exactly four single-select questions with four options each from the section's markdown files, following a quiz-rules reference that allows no hints. Weak concepts are rephrased in new contexts instead of repeated. Results are graded in a table with explanations, and progress is tracked at concept level in per-area files holding attempts, correct counts, dates, status and error notes, while the dashboard keeps only aggregated numbers.
When your agent uses it
- Taking a diagnostic of what you know across a StudyVault
- Reviewing a specific section with a short quiz
- Drilling concepts you got wrong in earlier sessions
- Checking learning progress on the dashboard
Example prompts
- “Quiz me on the networking section of my StudyVault.”
- “Run a diagnostic on everything I have not been tested on yet.”
- “Drill my weak areas from the earlier sessions.”
Requirements
- An Obsidian StudyVault folder in the project
Workflow steps
7 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 397110c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
StudyVault Quiz Tutor loads about 1.4k tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 94 tokens; SKILL.md has 518 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Interactive quiz tutor for Obsidian StudyVault learning. Use when the user wants to: (1) Take a diagnostic assessment of their knowledge, (2) Study or review specific sections/topics, (3) Drill weak areas identified in previous sessions, (4) Check their learning progress or dashboard, or says things like "quiz me", "test me", "let's study", "/tutor", "학습", "퀴즈", "평가".
Tutor Skill
Quiz-based tutor that tracks what the user knows and doesn't know at the concept level. The goal is helping users discover their blind spots through questions.
File Structure
StudyVault/
├── *dashboard* ← Compact overview: proficiency table + stats
└── concepts/
├── {area-name}.md ← Per-area concept tracking (attempts, status, error notes)
└── ...- Dashboard: Only aggregated numbers. Links to concept files. Stays small forever.
- Concept files: One per area. Tracks each concept with attempts, correct count, date, status, and error notes. Grows proportionally to unique concepts tested (bounded).
Workflow
Phase 0: Detect Language
Detect user's language from their message → {LANG}. All output and file content in {LANG}.
Phase 1: Discover Vault
- Glob
**/StudyVault/in project - List section directories
- Glob
**/StudyVault/*dashboard*to find dashboard - If found, read it. Preserve existing file path regardless of language.
- If not found, create from template (see Dashboard Template below)
If no StudyVault exists, inform user and stop.
Phase 2: Ask Session Type
MANDATORY: Use AskUserQuestion to let the user choose what to do. Analyze the dashboard to build context-aware options, then present them.
Read the dashboard proficiency table and build options based on current state:
- If unmeasured areas (⬜) exist → include "Diagnostic" option targeting those areas
- If weak areas (🟥/🟨) exist → include "Drill weak areas" option naming the weakest area(s)
- Always include "Choose a section" option so the user can pick any area
- If all areas are 🟩/🟦 → include "Hard-mode review" option
Present these as an AskUserQuestion with header "Session" and concise descriptions showing which areas each option targets. The user MUST select before proceeding.
Phase 3: Build Questions
- Read markdown files in target section(s)
- If drilling weak area: also read
concepts/{area}.mdto find 🔴 unresolved concepts — rephrase these in new contexts (don't repeat the same question) - Craft exactly 4 questions following
references/quiz-rules.md
CRITICAL: Read references/quiz-rules.md before crafting ANY question. Zero hints allowed.
Phase 4: Present Quiz
Use AskUserQuestion:
- 4 questions, 4 options each, single-select
- Header: "Q1. Topic" (max 12 chars)
- Descriptions: neutral, no hints
Show full SKILL.md (203 more words)Show less
Phase 5: Grade & Explain
- Show results table (question / correct answer / user answer / result)
- Wrong answers: concise explanation
- Map each question to its area
Phase 6: Update Files
1. Update concept file (concepts/{area}.md)
For each question answered:
- New concept: Add row to table + if wrong, add error note under
### 오답 메모(or localized equivalent) - Existing 🔴 concept answered correctly: Increment attempts & correct, change status to 🟢, keep error note (learning history)
- Existing 🟢 concept answered wrong again: Increment attempts, change status back to 🔴, update error note
Table format:
| Concept | Attempts | Correct | Last Tested | Status |
|---------|----------|---------|-------------|--------|
| concept name | 2 | 1 | 2026-02-24 | 🔴 |Error notes format (only for wrong answers):
### Error Notes
**concept name**
- Confusion: what the user mixed up
- Key point: the correct understanding2. Update dashboard
- Recalculate per-area stats from concept files (sum attempts/correct across all concepts in that area)
- Update proficiency badges: 🟥 0-39% · 🟨 40-69% · 🟩 70-89% · 🟦 90-100% · ⬜ no data
- Update stats: total questions, cumulative rate, unresolved/resolved counts, weakest/strongest
Dashboard stays compact — no session logs, no per-question details.
Dashboard Template
Create when no dashboard exists. Filename localized to {LANG}. Example in English:
# Learning Dashboard
> Concept-based metacognition tracking. See linked files for details.
---
## Proficiency by Area
| Area | Correct | Wrong | Rate | Level | Details |
|------|---------|-------|------|-------|---------|
(one row per section, last column = [[concepts/{area}]] link)
| **Total** | **0** | **0** | **-** | ⬜ Unmeasured | |
> 🟥 Weak (0-39%) · 🟨 Fair (40-69%) · 🟩 Good (70-89%) · 🟦 Mastered (90-100%) · ⬜ Unmeasured
---
## Stats
- **Total Questions**: 0
- **Cumulative Rate**: -
- **Unresolved Concepts**: 0
- **Resolved Concepts**: 0
- **Weakest Area**: -
- **Strongest Area**: -Concept File Template
Create per area when first question is asked. Example:
# {Area Name} — Concept Tracker
| Concept | Attempts | Correct | Last Tested | Status |
|---------|----------|---------|-------------|--------|
### Error Notes
(added as concepts are missed)Important Reminders
- ALWAYS read
references/quiz-rules.mdbefore creating questions - NEVER include hints in option labels or descriptions
- NEVER use "(Recommended)" on any option
- Randomize correct answer position
- After grading, ALWAYS update both concept file AND dashboard
- Communicate in user's language
