# Developmental Editing — Developmental Editing Methodology

Specialized editing knowledge used by the manuscript-editor agent when structurally editing manuscripts.

## Why Developmental Editing

Proofreading (spelling/grammar) is only 10% of editing. **Developmental editing** diagnoses and improves the manuscript's structure, narrative, characters, and pacing — the core work that determines a book's quality.

## Manuscript Structure Diagnostics: SPINE Check

| Element | Check Item | Diagnostic Question |
|---------|-----------|-------------------|
| **S**tructure | Overall structure | Does the table of contents create a logical flow? Does each chapter contribute to the whole? |
| **P**acing | Pacing | Are there sagging sections? Is the climax timing appropriate? |
| **I**ntention | Intent | Is the author's core message clear? |
| **N**arrative | Narrative/Logic | (Fiction) Is the narrative arc complete? (Non-fiction) Is the argumentation solid? |
| **E**ngagement | Reader engagement | Does the reader want to keep reading? Is the first chapter compelling? |

## Genre-Specific Editing Standards

### Business/Self-Help

| Editing Criterion | Ideal State | Common Problem |
|------------------|-------------|----------------|
| **Core Message** | Summarizable in one sentence | Multiple topics scattered randomly |
| **Structure** | Problem->Cause->Solution->Action or framework-centered | Anecdote listing with no system |
| **Case Studies** | At least 1 concrete case per chapter | Theory only, no cases |
| **Actionability** | Reader can take immediate action | Only abstract advice listed |
| **First Chapter** | Directly targets reader's pain/desire | Starts with author self-introduction |

### Fiction

| Editing Criterion | Ideal State | Common Problem |
|------------------|-------------|----------------|
| **Opening** | Tension/curiosity from the first page | Starts with scenery description or setting explanation |
| **Characters** | Protagonist has deficiency + desire + change | Flat, no change |
| **Conflict** | Conflict or tension in every chapter | Events listed without conflict |
| **Dialogue** | Unique speech patterns per character | All characters speak the same way |
| **Ending** | Emotional satisfaction + narrative resolution | Abrupt conclusion |

### Essay

| Editing Criterion | Ideal State | Common Problem |
|------------------|-------------|----------------|
| **Unique Perspective** | Author's distinctive viewpoint emerges | Generic observations anyone could make |
| **Sensory Description** | Concrete scenes, sensory details | Abstract emotional statements |
| **Structure** | Flow and thematic connections between essays | Random arrangement |
| **Depth** | Reflection beyond the surface | Diary-level recording |

## Pacing Analysis Tools

### Chapter Energy Mapping

Rate each chapter's energy level 1-10 and map:

```
Energy
10|        *
 8|    *       *
 6|  *   *       *   *
 4|*       *       *   *
 2|                       *
  +------------------------- Chapter
  1  2  3  4  5  6  7  8  9  10
```

### Pacing Problem Diagnosis

| Pattern | Problem | Solution |
|---------|---------|----------|
| Constantly high (8,9,8,9,8) | Reader fatigue, emotional numbness | Insert relaxation chapters |
| Constantly low (3,4,3,2,3) | Boredom, drop-off | Add conflict/crisis, merge chapters |
| Low first chapter (2) | Reader never starts | Move a powerful mid-section scene forward |
| Low ending (3) | Anti-climax | Redesign the ending |
| Midpoint slump (7,8,3,3,3,8) | Mid-section drop-off | Insert "midpoint reversal" |

## Editing Feedback Writing

### 3-Tier Editing Notes

| Tier | Scope | Example |
|------|-------|---------|
| **Macro** | Overall structure | "Swapping chapters 3 and 5 would improve logical flow" |
| **Medium** | Chapter/section level | "The latter half of this chapter drags. Keep only 1 core case study" |
| **Micro** | Sentence/paragraph | "This metaphor obscures the core message" |
