Complete implementation of md-explode command for transforming single markdown files into organized directory structures: Core Implementation: - MarkdownSection class for hierarchical document modeling - extract_headings() - Parse markdown headings with levels - parse_markdown_structure() - Build section hierarchy from content - generate_safe_filename() - Convert headings to filesystem-safe names - explode_markdown_file() - Main explosion functionality - DirectoryStructureBuilder - Create organized file/directory structures CLI Integration: - md-explode command with comprehensive options - --dry-run for previewing structure - --verbose for detailed output - --max-depth for limiting nesting - --output-dir for custom output location Key Features: - Hierarchical structure preservation (# → ## → ###) - Smart filename generation with Unicode support - Front matter handling and preservation - Content integrity maintenance - Cross-platform filesystem compatibility - Comprehensive error handling and validation Refactoring Applied: - Eliminated code duplication between filename functions - Extracted front matter processing into dedicated function - Modularized CLI command with helper functions - Improved error handling and user feedback Documentation: - Complete API documentation with docstrings - Comprehensive user documentation (docs/md-explode-command.md) - Usage examples and troubleshooting guide - Integration instructions with other MarkiTect commands Testing: 47 comprehensive tests covering all functionality Status: Production-ready, full TDD8 cycle completed Performance: Efficient for documents with thousands of sections 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
