| 1 | Chapter drafts → scene extraction → illustration prompts → style consistency → placement plan. |
| 2 | |
| 3 | **Input**: PRD.md, STYLE.md, outline.md, drafts/ directory. |
| 4 | |
| 5 | ## Scene Extraction |
| 6 | |
| 7 | Read each chapter draft. Identify 2-4 illustration-worthy moments per chapter using these criteria: |
| 8 | - **Fiction**: Key dramatic moments, character introductions, setting reveals, turning points, climactic scenes |
| 9 | - **Nonfiction**: Key concepts, data visualizations, diagrams, process flows, before/after comparisons |
| 10 | - **Poetry**: Evocative imagery, symbolic motifs, mood-setting landscapes |
| 11 | |
| 12 | For each identified scene, extract: |
| 13 | - Chapter number and approximate location (opening, middle, closing) |
| 14 | - Scene description (1-2 sentences, vivid visual language) |
| 15 | - Narrative context (why this moment deserves illustration) |
| 16 | - Suggested illustration type: `full-page`, `chapter-header`, `inline`, `spot` |
| 17 | |
| 18 | ## Style Bible |
| 19 | |
| 20 | Read STYLE.md for art direction. If no explicit illustration style is defined, infer from genre: |
| 21 | |
| 22 | | Genre | Default Style | Reference Artists | |
| 23 | |-------|--------------|-------------------| |
| 24 | | Fantasy | Oil painting, rich detail, dramatic lighting | Frazetta, Ruth | |
| 25 | | SF | Clean digital, neon/steel palette, geometric | Sparth, Daniel Dociu | |
| 26 | | Thriller | High contrast, noir lighting, fragmented composition | Greg Manchess | |
| 27 | | Romance | Soft watercolor, warm tones, figure-focused | ? |
| 28 | | Literary | Minimalist ink, texture, abstract | | |
| 29 | | Poetry | Abstract watercolor, ethereal, symbolic | | |
| 30 | | Technical | Clean vector, diagram-friendly, 2-color | | |
| 31 | | Children's | Bright, whimsical, character-centric | | |
| 32 | |
| 33 | Generate a **style seed prompt** — a reusable prefix for all illustration prompts to ensure consistency: |
| 34 | ``` |
| 35 | [Style medium], [color palette], [lighting], [composition style], [mood] — |
| 36 | ``` |
| 37 | |
| 38 | ## Prompt Generation |
| 39 | |
| 40 | For each scene, generate prompts in 3 tiers: |
| 41 | |
| 42 | ### Tier 1: Background Art (cover-quality) |
| 43 | ``` |
| 44 | [Style seed] + [Scene description], [Aspect ratio], [Composition], no text, no watermark, no logo --ar [ratio] |
| 45 | ``` |
| 46 | |
| 47 | ### Tier 2: Concept Sketch |
| 48 | ``` |
| 49 | [Style seed] + [Scene description], rough pencil sketch, simple lines, composition study --ar [ratio] |
| 50 | ``` |
| 51 | |
| 52 | ### Tier 3: Spot Illustration (decorative) |
| 53 | ``` |
| 54 | [Style seed] + simplified [scene motif], isolated on white background, small decorative element |
| 55 | ``` |
| 56 | |
| 57 | **Aspect ratios by type**: |
| 58 | - `full-page`: `--ar 2:3` (matches book page) |
| 59 | - `chapter-header`: `--ar 3:1` (wide banner) |
| 60 | - `inline`: `--ar 1:1` (square) |
| 61 | - `spot`: `--ar 1:1` (small square) |
| 62 | |
| 63 | ## Quality Guard |
| 64 | |
| 65 | Skip scenes that: |
| 66 | - Primarily involve dialogue (no strong visual) |
| 67 | - Are too abstract to illustrate concretely |
| 68 | - Would duplicate a similar scene already illustrated in another chapter |
| 69 | |
| 70 | ## Output |
| 71 | |
| 72 | Write to `publish/illustrations/plan.md` with: |
| 73 | |
| 74 | ```markdown |
| 75 | # Illustration Plan: {book title} |
| 76 | |
| 77 | ## Style Seed |
| 78 | {Reusable style prompt prefix} |
| 79 | |
| 80 | ## Illustrations |
| 81 | |
| 82 | ### Chapter {N}: {chapter title} |
| 83 | |
| 84 | #### {N}.1 — {scene name} [{type}] |
| 85 | - **Location**: {opening|middle|closing} |
| 86 | - **Context**: {why this scene} |
| 87 | - **Description**: {visual description} |
| 88 | - **Prompt**: |
| 89 | ``` |
| 90 | {generated prompt} |
| 91 | ``` |
| 92 | - **Palette**: {2-3 dominant colors with hex} |
| 93 | ``` |
| 94 | |
| 95 | Also write a summary to `publish/illustrations/manifest.json`: |
| 96 | ```json |
| 97 | { |
| 98 | "style_seed": "...", |
| 99 | "total_illustrations": N, |
| 100 | "by_chapter": { "ch01": 2, "ch02": 3, ... }, |
| 101 | "by_type": { "full-page": N, "chapter-header": N, "inline": N, "spot": N }, |
| 102 | "generated_at": "ISO-8601" |
| 103 | } |
| 104 | ``` |
