markitdown

Quick Review

Excellent skill with comprehensive documentation. The description clearly covers all capabilities (15+ file formats, OCR, transcription, AI-enhanced descriptions). Task knowledge is outstanding with detailed installation, API usage, CLI commands, and 6+ real-world use cases with complete code examples. Structure is very clear with logical sections, though SKILL.md is somewhat lengthy - however, this is justified given the complexity and breadth of features, and referenced files (batch_convert.py, convert_with_ai.py, api_reference.md, etc.) appropriately handle additional details. Novelty is strong: while file conversion exists, orchestrating MarkItDown with OCR, audio transcription, AI vision models, and batch processing across 15+ formats meaningfully reduces token costs and complexity versus a CLI agent attempting this manually. The integration with OpenRouter for AI-enhanced image descriptions and the scientific workflow examples add significant value. Minor deduction on novelty as basic file conversion is somewhat common, but the comprehensive multi-format support with advanced features justifies high scoring.
