Note Split (Atomization)

Goal

Turn one long, fuzzy document into multiple notes that can stand alone and connect cleanly.

Quick start

• Identify 3–7 candidate atomic concepts.
• For each new note: one-sentence core + original source location + ≥2 link suggestions.

Workflow

Step 1: Concept identification (three layers)

1. Surface concepts (explicit terms)
2. Implicit concepts (assumptions / premises)
3. Core insight (what the author really claims)

Step 2: Boundary test

• If removing any part breaks the concept, it’s not atomic yet.
• If the concept can explain other phenomena, it’s a good atomic note.

Step 3: Split plan

Provide a mapping table:

• original section → new note title → core concept → note type (concept/method/case)

Step 4: Title patterns

• Definition: “What is X? core elements”
• Method: “Method X: key steps”
• Insight: “On [topic]: [insight]”

Step 5: Links

Include:

• sibling links (notes split from the same source)
• topical links (same theme)
• contrast links (alternative view / counterexample)

Output template

## 📋 Split Plan

### Source note
- **File**: [name]
- **Length**: [words/lines]
- **Concepts identified**: [N]

### Proposed new notes

#### 1) [New note title]
- **Core concept**: [one sentence]
- **Source location**: [section/paragraph]
- **Suggested links**: [[Link 1]] [[Link 2]]

### Keep-as-index suggestion
- Keep the original as an index note? yes/no (why)

Quality checks

• Each new note is atomic and independently understandable
• Each includes source location
• Clear linking between split notes and the wider network
