Implemented comprehensive content command family for MarkdownMatters CLI following TDD8 methodology and MarkdownMatters specification. ## TDD8 Cycle 1 - Content Commands ### Core Implementation - Content parser for extracting main content without matter zones - Content statistics calculator (words, lines, paragraphs, characters) - CLI commands: `content-get` and `content-stats` - Full integration with existing markitect CLI ### MarkdownMatters Compliance - Correctly removes YAML/TOML/JSON frontmatter - Correctly removes tailmatter blocks (`yaml tailmatter`, `json tailmatter`) - Preserves contentmatter (MultiMarkdown key-value pairs within content) - Follows three-zone specification from wiki/MarkdownMatters.md ### Module Structure ``` markitect/content/ ├── __init__.py # Module exports ├── parser.py # ContentParser with matter zone removal ├── stats.py # ContentStats data class └── commands.py # CLI commands implementation ``` ### CLI Commands Added - `markitect content-get --file [path]` - Extract pure content - `markitect content-stats --file [path]` - Calculate content statistics ### Test Coverage - 16 comprehensive tests covering all scenarios - Test fixtures for different document types - CLI integration tests with Click testing - Edge case handling (file not found, empty content, etc.) ### Validation Results - All tests pass (16/16) - Manual CLI testing confirmed - Proper matter zone separation validated - Statistics calculation accuracy verified ## Technical Architecture ### ContentParser Class - `extract_content()` - Remove frontmatter and tailmatter - `calculate_stats()` - Generate comprehensive statistics - `_remove_frontmatter()` - YAML frontmatter removal - `_remove_tailmatter()` - Tailmatter block removal ### ContentStats Data Class - word_count, line_count, paragraph_count, character_count - JSON serialization support via `to_dict()` ## GAMEPLAN Progress - ✅ TDD8 Cycle 1: Content Commands (COMPLETE) - 🔄 Next: Cycle 2 - Frontmatter Commands - Remaining: Contentmatter, Tailmatter command families This implements the foundation for Issue #38 with 6 remaining cycles planned for complete MarkdownMatters CLI functionality. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
