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(excludenode_modules/,.git/,dist/,build/,StudyVault/). Present for user confirmation.
- Extract text (MANDATORY tools):
- **PDF →
pdftotextCLI 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.txtfirst, then Read the.txtfile.
pdftotext "source.pdf" "/tmp/source.txt"
- If
pdftotextis not installed, install it first:brew install poppler(macOS) orapt-get install poppler-utils(Linux).
- URL → WebFetch
- Other formats (
.md,.txt,.html) → Read directly.
- **Read extracted
.txtfiles** — 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 보기fold callout
- Patterns use
> [!hint]-/> [!summary]-fold callouts
- Question type diversity: ≥60% recall, ≥20% application, ≥2 analysis per file
## Related Conceptswith[[wiki-links]]
Phase D8: Interlinking
## Related Noteson 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.
