.claude/skills/markitdown/# MarkItDown - File to Markdown Conversion ## Overview MarkItDown is a Python tool developed by Microsoft for converting various file formats to Markdown. It's particularly useful for converting documents into LLM-friendly text format, as Markdown is token-efficient and well-understood by modern language models. **Key Benefits**: - Convert documents to clean, structured Markdown - Token-efficient format for LLM processing - Supports 15+ file formats - Optional AI-enhanced image descriptions - OCR for images and scanned documents - Speech transcription for audio files ## Visual Enhancement with Scientific Schematics **When creating documents with this skill, always consider adding scientific diagrams and schematics to enhance visual communication.** If your document does not already contain schematics or diagrams: - Use the **scientific-schematics** skill to generate AI-powered publication-quality diagrams - Simply describe your desired diagram in natural language - Nano Banana Pro will automatically generate, review, and refine the schematic **For new documents:** Scientific schematics should be generated by default to visually represent key concepts, workflows, architectures, or relationships described in the text. **How to generate schematics:** ```bash python scripts/generate_schematic.py "your diagram description" -o figures/output.png ``` The AI will automatically: - Create publication-quality images with proper formatting - Review and refine through multiple iterations - Ensure accessibility (colorblind-friendly, high contrast) - Save outputs in the figures/ directory **When to add schematics:** - Document conversion workflow diagrams - File format architecture illustrations - OCR processing pipeline diagrams - Integration workflow visualizations - System architecture diagrams - Data flow diagrams - Any complex concept that benefits from visualization For detailed guidance on creating schematics, refer to the scientific-schematics skill documentatio
