Obsidian Study Vault Builder

Comprehensive patterns for building exam-ready study vaults in Obsidian

Build structured, mobile-compatible academic study vaults with systematic error prevention, quality assurance, and efficiency patterns extracted from real-world projects.

⚠️ IMPORTANT: See REFERENCE.md for complete battle-tested patterns from 828KB/37-file vault projects.

When to Use This Skill

Invoke when building academic study materials in Obsidian for:

• Final exam preparation (any subject)
• Course knowledge organization (CS, medicine, business, law, etc.)
• Self-study material structuring
• Technical documentation vaults
• Large-scale study projects (10+ files, 200KB+)

Works across all subjects:

• Computer Science (algorithms, data structures, systems)
• Medicine (anatomy, pharmacology, pathology)
• Business (finance, marketing, operations)
• STEM (physics, chemistry, engineering)
• Humanities (history, literature, philosophy)

Core Methodology

Checkpoint-Based Workflow (Critical)

Never generate all chapters upfront. Use progressive validation:

1. Chapter 1 Generation → STOP
2. User Review → Approve format, structure, quality
3. Chapters 2-N → Continue with validated pattern
4. Final QA → Systematic verification

Why this matters:

• Catches format issues before they multiply across 30+ files
• Validates approach matches user needs early
• Adjusts course when cheap (Chapter 1) vs expensive (Chapter 8)
• Prevents 5+ hours of rework

Time breakdown: Chapter 1 (30 min) → Review (15 min) → Remaining (90 min) → QA (30 min) = 2.5 hours vs 80 hours manual

Memory File Hierarchy

Three-level context structure (see REFERENCE.md for details):

• Level 1: Root vault (CLAUDE.md)
• Level 2: Subject folder (School/CLAUDE.md)
• Level 3: Course project (School/algorithms/CLAUDE.md)

Universal Obsidian Features (Mobile-First)

✅ Use only: Mermaid diagrams, LaTeX math, standard callouts, internal links, tables, code blocks ❌ Never use: Dataview queries, custom callouts, plugins

See REFERENCE.md for complete patterns.

Error Pattern Recognition (8 Patterns)

Pattern 1: Unicode Corruption in Mermaid

• Symptom: Diagrams fail to render
• Diagnosis: grep -r "≤\|≥\|∞\|∈\|≠\|→" *.md
• Fix: Replace with ASCII (<=, >=, infinity, in, !=, ->)

Pattern 2: Broken Tables (LaTeX Pipes)

• Diagnosis: grep -r "| \$.*|.*\$" *.md
• Fix: Escape pipes: | → \|

Pattern 3: Missing Collapsible Solutions

• Diagnosis: grep -A 5 "## Problem" practice-problems.md | grep -v "\[!example\]-"
• Fix: Use > [!example]- Solution

Pattern 4-8: See REFERENCE.md

• Inconsistent navigation
• Missing learning objectives
• Inconsistent TOC
• Empty core concepts
• Broken cross-references

Content Quality Patterns

Applied Understanding (Not Memorization)

Good questions:

• "Design [system] for [context]. Current [problem]. Describe solution to achieve [goal]. Analyze trade-offs and justify."

Adapts to subject:

• CS: Algorithm design scenarios
• Medicine: Case-based diagnosis
• Business: Strategic analysis
• Physics: Experimental design

Comprehensive Coverage

Every topic from source materials must appear. Validation: cross-reference source outline with vault TOC.

Cross-Reference Pattern

Link related concepts everywhere with [[links]].

See REFERENCE.md for complete examples.

Standard Vault Structure

course-name/
├── 00-overview/          # Course map, schedule, strategy
├── 01-chapter-name/      # Core concepts, quick-ref, practice
├── cross-chapter/        # Comparisons, patterns, catalog
└── mock-exams/           # Practice tests + solutions

---

Quality Assurance (Summary)

Before marking complete:

• Structural consistency (navigation, objectives, TOC)
• Content completeness (all topics covered)
• Format correctness (no Unicode in Mermaid, LaTeX pipes escaped)
• Mobile compatibility (no plugins)
• Assessment alignment (practice matches exam style)

See REFERENCE.md for complete 50+ item checklist.

Common Anti-Patterns

1. "I'll Fix It Later" → Fix immediately
2. Generating Without Checkpoints → Chapter 1 → Review → Continue
3. Forgetting Mobile Users → Universal features only
4. Surface-Level Practice → Scenario-based with reasoning

---

Success Metrics

Typical project:

• Files: 30-40
• Size: 600-900KB
• Coverage: 100% of source topics
• Rendering errors: 0
• Time saved: 80+ hours
• Practice problems: 80-100
• Mock exams: 2-3

Integration Patterns

Task Agents for Large Analysis

For 100+ pages of materials, use Task tool with subagent_type=Explore.

Git Workflow

git commit -m "Initial vault structure"
git commit -m "Complete Chapter 1 (checkpoint)"
git commit -m "Complete: Study vault (37 files, 828KB)"
