description	Use AI to merge individual page HTML files into a unified chapter document. Creates continuous document format for improved reading experience and semantic consistency.

AI Chapter Consolidate Skill

Purpose

This skill uses AI to intelligently merge individual page HTML files into a single, continuous chapter document. Rather than simple concatenation, the AI:

Removes duplicate headers/footers from continuation pages
Ensures consistent heading hierarchy across pages
Maintains semantic structure throughout
Preserves all content without loss or repetition
Creates smooth content flow (no page breaks)

The result is a unified chapter document in the continuous format (single page-container, single page-content).

What to Do

Collect all page HTML files for chapter
- Gather 04_page_XX.html files for all pages in chapter
- Verify all files exist and are valid
- Sort by page number (ascending)
Extract content from each page
- Load each HTML file
- Extract main content from <main class="page-content">
- Preserve semantic classes and structure
Prepare consolidation inputs for AI
- Page 1: Full content including chapter header
- Pages 2+: Extract content sections, remove chapter header/nav
- Preserve all text and structure
- Note any special sections (exhibits, tables, etc.)
Invoke AI consolidation
- Send all page contents to Claude
- Request merging into single continuous document
- Specify structural requirements
- Request heading hierarchy normalization
Process AI output
- Extract consolidated HTML from response
- Verify structure integrity
- Ensure all pages represented
- Check heading hierarchy
Save consolidated document
- Save to: output/chapter_XX/chapter_artifacts/chapter_XX.html
- Create metadata/log file
- Calculate statistics

Input Files

Per-page HTML files (validated by previous gate):

output/chapter_XX/page_artifacts/page_16/04_page_16.html (Chapter opening)
output/chapter_XX/page_artifacts/page_17/04_page_17.html (Continuation)
output/chapter_XX/page_artifacts/page_18/04_page_18.html (Continuation)
... (all pages in chapter)

Chapter metadata (from analysis):

Page range (first and last page of chapter)
Chapter number
Chapter title
Expected page count

AI Consolidation Prompt

The prompt sent to Claude:

You are merging individual page HTML documents into a single, continuous chapter.

INPUT PAGES:

Page 1 (Opening - include chapter header):
[HTML content from page 1]

Page 2 (Continuation):
[HTML content from page 2]

Page 3 (Continuation):
[HTML content from page 3]

... (all pages)

TASK:
Merge these pages into a single HTML document that reads as one continuous chapter.

REQUIREMENTS:

1. Structure:
   - Create single <div class="page-container"> wrapping everything
   - Create single <main class="page-content"> for all content
   - Remove page-break indicators or comments
   - Create truly continuous document (no paginated elements)

2. Chapter Header:
   - Keep chapter header from Page 1 (chapter number, title)
   - Remove chapter headers/titles from continuation pages
   - Keep section navigation if present on Page 1
   - Remove duplicate navigation from other pages

3. Content Preservation:
   - Include ALL text content from all pages
   - Preserve exact wording (no paraphrasing)
   - Maintain all lists, paragraphs, tables
   - Include all semantic classes
   - Keep all HTML structure

4. Heading Hierarchy:
   - Normalize heading levels across merged pages
   - Page 1 h1 = Chapter title (stays as h1)
   - First section in each page = h2 (main sections)
   - Sub-sections = h3 or h4 as needed
   - Ensure no hierarchy jumps (h1 → h3 without h2)
   - Number consecutive headings logically

5. Content Flow:
   - Remove page-specific headers/footers
   - Merge seamlessly so content flows naturally
   - No artificial breaks or transitions
   - Paragraphs continue logically
   - Lists maintain coherence

6. Exhibits and Images:
   - Preserve all tables and figures
   - Keep exhibit titles and captions
   - Include all images with proper paths
   - Maintain table of contents if present

7. CSS Classes:
   - Preserve all semantic classes (section-heading, paragraph, etc.)
   - Keep consistent class usage throughout
   - Ensure classes match chapter opening page style
   - Do not add or remove classes

8. Metadata:
   - Include title tag: "Chapter N: Title - Pages X-Y"
   - Keep meta charset and viewport
   - Link stylesheet: <link rel="stylesheet" href="../../styles/main.css">

OUTPUT:

Return ONLY a single, valid HTML5 document:

```html
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Chapter [N]: [Title] - Pages [X-Y]</title>
    <link rel="stylesheet" href="../../styles/main.css">
</head>
<body>
    <div class="page-container">
        <main class="page-content">
            <!-- All content from all pages, merged seamlessly -->
        </main>
    </div>
</body>
</html>

VALIDATION:

Single HTML5 document
All pages represented
No page breaks or transitions
Proper heading hierarchy
All text preserved


## Page Content Extraction Logic

Before sending to AI, extract content strategically:

### Page 1 (Opening):
- **Include**: Entire page HTML content
- **Reason**: Contains chapter header, navigation, first section
- **Preserve**: All elements (header, nav, dividers, content)

### Pages 2-N (Continuation):
- **Extract**: Only content after chapter header
- **Skip**: Chapter number, chapter title, section navigation
- **Preserve**: Section headings, paragraphs, lists, exhibits
- **Include**: All semantic content sections

### Example extraction:
```html
<!-- Page 1: Keep everything -->
<div class="chapter-header">
    <span class="chapter-number">2</span>
    <h1 class="chapter-title">Rights in Real Estate</h1>
</div>
<nav class="section-navigation">...</nav>
<h2 class="section-heading">REAL PROPERTY RIGHTS</h2>
<p class="paragraph">...</p>

<!-- Page 2: Skip header, keep content -->
<!-- <div class="chapter-header">...</div> SKIPPED -->
<!-- <nav class="section-navigation">...</nav> SKIPPED -->
<h4 class="subsection-heading">Physical characteristics.</h4>
<p class="paragraph">...</p>
<ul class="bullet-list">...</ul>

<!-- Page 3: Continue same pattern -->
<h4 class="subsection-heading">Interdependence.</h4>
<p class="paragraph">...</p>

Implementation

Execute consolidation via Python wrapper:

cd Calypso/tools

# Run consolidation
python3 consolidate_chapter.py \
  --chapter 2 \
  --pages 15-28 \
  --output "../output" \
  --mapping "../analysis/page_mapping.json"

# Or invoke directly via Claude API:
# The orchestrator sends the AI prompt with all page contents

Quality Checks

Before passing to next gate:

File created
- chapter_XX.html exists
- File is valid HTML (parseable)
- File size reasonable (> 50KB typical)
Structure validated
- Single <div class="page-container">
- Single <main class="page-content">
- All tags properly closed
- No duplicate content
Content completeness
- All pages represented
- No missing sections
- Paragraph/heading counts reasonable
- All text content present
Heading hierarchy
- Starts with h1 (chapter title)
- h1 count = 1
- h2 = major sections
- h3/h4 = subsections
- No hierarchy jumps
Metadata logged
- Consolidation timestamp recorded
- Pages merged count documented
- Content statistics calculated
- Log file saved

Success Criteria

✓ All pages merged into single document ✓ Chapter header preserved from page 1 ✓ Duplicate headers removed from continuation pages ✓ Content flows naturally (continuous format) ✓ Heading hierarchy is correct ✓ All text content preserved ✓ Semantic classes maintained ✓ Ready for semantic validation

Error Handling

If page HTML is incomplete:

Note in consolidation log
Include whatever content is available
Proceed to validation (validation will catch issues)

If heading hierarchy is ambiguous:

AI makes best judgment
Semantic validation gate will refine if needed
Document decision in log

If content appears duplicated:

AI deduplicates automatically
Verify word count is reasonable
Log any unusual content patterns

Next Steps

Once consolidation completes:

Quality Gate 2 (semantic-validate) checks semantic structure
Skill 5 (quality-report-generate) generates final report
Quality Gate 3 (visual-accuracy-check) validates appearance

Design Notes

This skill is AI-powered (uses probabilistic consolidation)
Relies on AI's understanding of document structure
Produces continuous format (no page breaks)
Merges intelligently (not just concatenation)
Output will be refined by validation gates

Testing

To test consolidation on Chapter 2:

# Input: 14 individual page HTML files (pages 16-29)
# Process: AI merges into single continuous chapter
# Output: chapter_02.html (single, unified document)

# Verify:
# - File size is sum of all pages
# - Content flows logically
# - Heading hierarchy makes sense
# - No duplicate sections
