Tutor Setup Agent Skill

Tutor Setup — Knowledge to Obsidian StudyVault

CWD Boundary Rule (ALL MODES)

> NEVER access files outside the current working directory (CWD).

> All source scanning, reading, and vault output MUST stay within CWD and its subdirectories.

> If the user provides an external path, ask them to copy the files into CWD first.

Mode Detection

On invocation, detect mode automatically:

• Check for project markers in CWD:
• package.json, pom.xml, build.gradle, Cargo.toml, go.mod, Makefile,

*.sln, pyproject.toml, setup.py, Gemfile

• If any marker found → Codebase Mode
• If no marker found → Document Mode
• Tie-break: If .git/ is the sole indicator and no source code files (*.ts, *.py, *.java, *.go, *.rs, etc.) exist, default to Document Mode.
• Announce detected mode and ask user to confirm or override.

Document Mode

> Transforms knowledge sources (PDF, text, web, epub) into study notes.

> Templates: templates.md

Phase D1: Source Discovery & Extraction

• Auto-scan CWD for /*.pdf, /*.txt, /*.md, /*.html, **/*.epub (exclude node_modules/, .git/, dist/, build/, StudyVault/). Present for user confirmation.
• Extract text (MANDATORY tools):
• PDF → pdftotext CLI ONLY (run via Bash tool). NEVER use the Read tool directly on PDF files — it renders pages as images and wastes 10-50x more tokens. Convert to .txt first, then Read the .txt file.

     pdftotext "source.pdf" "/tmp/source.txt"

• If pdftotext is not installed, install it first: brew install poppler (macOS) or apt-get install poppler-utils (Linux).
• URL → WebFetch
• Other formats (.md, .txt, .html) → Read directly.
• Read extracted .txt files — understand scope, structure, depth. Work exclusively from the converted text, never from the raw PDF.
• Source Content Mapping (MANDATORY for multi-file sources):
• Read cover page + TOC + 3+ sample pages from middle/end for EVERY source file
• NEVER assume content from filename — file numbering often ≠ chapter numbering
• Build verified mapping: { source_file → actual_topics → page_ranges }
• Flag non-academic files and missing sources
• Present mapping to user for verification before proceeding

Phase D2: Content Analysis

• Identify topic hierarchy — sections, chapters, domain divisions.
• Separate concept content vs practice questions.
• Map dependencies between topics.
• Identify key patterns — comparisons, decision trees, formulas.
• Full topic checklist (MANDATORY) — every topic/subtopic listed. Drives all subsequent phases.

> Equal Depth Rule: Even a briefly mentioned subtopic MUST get a full dedicated note supplemented with textbook-level knowledge.

• Classification completeness: When source enumerates categories ("3 types of X"), every member gets a dedicated note. Scan for: "types of", "N가지", "categories", "there are N".
• Source-to-note cross-verification (MANDATORY): Record which source file(s) and page range(s) cover each topic. Flag untraceable topics as "source not available".

Phase D3: Tag Standard

Define tag vocabulary before creating notes:

• Format: English, lowercase, kebab-case (e.g., #data-hazard)
• Hierarchy: top-level → domain → detail → technique → note-type
• Registry: Only registered tags allowed. Detail tags co-attach parent domain tag.

Phase D4: Vault Structure

Create StudyVault/ with numbered folders per templates.md. Group 3-5 related concepts per file.

Phase D5: Dashboard Creation

Create 00-Dashboard/: MOC, Quick Reference, Exam Traps. See templates.md.

• MOC: Topic Map + Practice Notes + Study Tools + Tag Index (with rules) + Weak Areas (with links) + Non-core Topic Policy
• Quick Reference: every heading includes → [[Concept Note]] link; all key formulas
• Exam Traps: per-topic trap points in fold callouts, linked to concept notes

Phase D6: Concept Notes

Per templates.md. Key rules:

• YAML frontmatter: source_pdf, part, keywords (MANDATORY)
• source_pdf MUST match verified Phase D1 mapping — never guess from filename
• If unavailable: source_pdf: 원문 미보유
• [[wiki-links]], callouts ([!tip], [!important], [!warning]), comparison tables > prose
• ASCII diagrams for processes/flows/sequences
• Simplification-with-exceptions: general statements must note edge cases

Phase D7: Practice Questions

Per templates.md. Key rules:

• Every topic folder MUST have a practice file (8+ questions)
• Active recall: answers use > [!answer]- 정답 보기 fold callout
• Patterns use > [!hint]- / > [!summary]- fold callouts
• Question type diversity: ≥60% recall, ≥20% application, ≥2 analysis per file
• ## Related Concepts with [[wiki-links]]

Phase D8: Interlinking

• ## Related Notes on every concept note
• MOC links to every concept + practice note
• Cross-link concept ↔ practice; siblings reference each other
• Quick Reference sections → [[Concept Note]] links
• Weak Areas → relevant note + Exam Traps; Exam Traps → concept notes

Phase D9: Self-Review (MANDATORY)

Verify against quality-checklist.md Document Mode section. Fix and re-verify until all checks pass.

Codebase Mode

> Generates a new-developer onboarding StudyVault from a source code project.

> Full workflow: codebase-workflow.md

> Templates: codebase-templates.md

Phase Summary

| Phase | Name | Key Action |

|-------|------|------------|

| C1 | Project Exploration | Scan files, detect tech stack, read entry points, map directory layout |

| C2 | Architecture Analysis | Identify patterns, trace request flow, map module boundaries and data flow |

| C3 | Tag Standard | Define #arch-*, #module-*, #pattern-*, #api-* tag registry |

| C4 | Vault Structure | Create StudyVault/ with Dashboard, Architecture, per-module, DevOps, Exercises folders |

| C5 | Dashboard | MOC (Module Map + API Surface + Getting Started + Onboarding Path) + Quick Reference |

| C6 | Module Notes | Per-module notes: Purpose, Key Files, Public Interface, Internal Flow, Dependencies |

| C7 | Onboarding Exercises | Code reading, configuration, debugging, extension exercises (5+ per major module) |

| C8 | Interlinking | Cross-link modules, architecture ↔ implementations, exercises ↔ modules |

| C9 | Self-Review | Verify against quality-checklist.md Codebase Mode section |

See codebase-workflow.md for detailed per-phase instructions.

Language

• Match source material language (Korean → Korean notes, etc.)
• Tags/keywords: ALWAYS English
