Example Usage in VS Code

1. Basic PDF Conversion:

   User: "Convert my document.md to PDF"
   → Triggers: convert_markdown_to_pdf

2. Multi-Rendering Optimization:

   User: "Generate the best quality PDF for my research paper"
   → Triggers: multi_render_pdf_optimal

3. Quality Analysis:

   User: "Show me the quality report for my document"
   → Triggers: get_quality_report

📊 Quality Metrics

The system evaluates each PDF variant on six key criteria:

| Metric | Weight | Description | |--------|--------|-------------| | Text Overlap Prevention | 25% | Detects overlapping text, ensures proper spacing | | Typography Consistency | 15% | Font hierarchy, consistent sizing, professional appearance | | Diagram Clarity | 20% | Mermaid diagrams properly sized, clear, within boundaries | | Page Break Quality | 15% | Logical breaks, no orphaned content, proper flow | | Professional Appearance | 15% | Overall document polish, business/academic standards | | Overall Readability | 10% | Easy to read layout, well-structured, accessible |

🧠 Learning System

The system continuously improves through:

• Document Type Recognition - Automatically optimizes for different content types
• Performance Tracking - Records quality metrics for each variant
• User Preference Learning - Adapts based on manual selections
• Pattern Recognition - Identifies successful configurations
• Optimization Strategies - Builds knowledge base of effective approaches
