$ npx skills add microsoft/markitdownHow to use this guide
Decide whether the agent needs markdown, JSON fields, tables, screenshots, or source citations.
Try a real target page with navigation, dynamic content, and imperfect markup.
Pair extraction with RAG, document processing, or data analysis only after the crawler is stable.
Evaluation notes
Scraping quality is about reliability, output shape, and maintainability. A high-star crawler still needs to prove it can return clean data for your target pages.
Use crawling skills for research agents, RAG ingestion, monitoring workflows, lead enrichment, and any agent that needs fresh web context.
