## What it does

The skill scans for a `StudyVault/` directory in your project workspace and reads markdown notes across sections. It generates a 4-question multiple-choice quiz adhering to rules that forbid hints in question text or options. Before quizzing, it prompts you to choose a session type: run a diagnostic, drill known weak spots, or pick a specific section.

Every answered quiz updates both an aggregated dashboard and area files in `concepts/{area}.md`. The tracker logs attempt counts, dates, status badges, and error notes explaining specific misunderstandings. If no `StudyVault` directory exists in the workspace, the skill stops immediately.

## Requirements
- Works with: Obsidian

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add bevibing/tutor-skills --skill tutor -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/tutor/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/tutor/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add bevibing/tutor-skills --skill tutor -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/tutor/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add bevibing/tutor-skills --skill tutor -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/tutor/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install bevibing/tutor-skills tutor
```

2. **Manually: put the files in place**
- File: `.github/skills/tutor/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add bevibing/tutor-skills --skill tutor -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/bevibing/tutor-skills --path skills/tutor
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/tutor/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add bevibing/tutor-skills --skill tutor -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/bevibing/tutor-skills/tree/HEAD/skills/tutor/SKILL.md

## When to use it
- discover blind spots in Obsidian study notes
- drill unresolved concepts flagged in previous quiz sessions
- track mastery rates across subject areas in a markdown dashboard
- run diagnostic assessments across unmeasured learning sections

## Example prompts
- quiz me on my study vault notes
- /tutor
- let's drill my weak areas from the dashboard

  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

1. Glob `**/StudyVault/` in project
2. List section directories
3. Glob `**/StudyVault/*dashboard*` to find dashboard
4. If found, read it. Preserve existing file path regardless of language.
5. 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:

1. If unmeasured areas (⬜) exist → include "Diagnostic" option targeting those areas
2. If weak areas (🟥/🟨) exist → include "Drill weak areas" option naming the weakest area(s)
3. Always include "Choose a section" option so the user can pick any area
4. 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

1. Read markdown files in target section(s)
2. If drilling weak area: also read `concepts/{area}.md` to find 🔴 unresolved concepts — rephrase these in new contexts (don't repeat the same question)
3. 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

### Phase 5: Grade & Explain

1. Show results table (question / correct answer / user answer / result)
2. Wrong answers: concise explanation
3. 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)
