ASCII Preview Generate Skill

Purpose

This skill uses AI to create a meaningful ASCII text-based representation of the PDF page layout. The AI:

Analyzes both the PDF page image and extracted text data
Creates a structured ASCII preview showing page organization
Represents heading hierarchy, paragraphs, lists, and tables visually
Provides clear structural context for downstream HTML generation

The ASCII preview serves as a structured representation of page layout, enabling the downstream AI-HTML generator to understand both visual layout and content structure.

What to Do

Load input files
- Read 02_page_XX.png (visual reference)
- Read 01_rich_extraction.json (text spans with metadata)
- Verify all required fields present
Invoke AI to analyze and represent
- Send PNG image to Claude (visual reference)
- Include extracted text data (JSON)
- Request ASCII layout representation
- AI determines structure and relationships
AI generates ASCII preview
- AI analyzes heading hierarchy from extraction data
- AI identifies paragraphs and their relationships
- AI represents lists with proper formatting
- AI shows table layouts if present
- AI creates visual representation using ASCII characters
Validate ASCII output
- Verify output is readable text
- Check that all content elements represented
- Confirm structure is clear and logical
Save to persistent file
- Save to: output/chapter_XX/page_artifacts/page_YY/03_page_XX_ascii.txt
- Include metadata (page number, chapter, timestamp)
