clean-web-markdown-skill

Retrieve clean markdown from webpages for AI agents using protocol-level content negotiation and crawl-to-markdown fallbacks. Use when users ask to fetch/read/summarize websites with low-noise markdown, to improve web_fetch quality, or to process JS-heavy pages via Jina/Firecrawl. Chinese trigger cues include: "抓网页正文", "提取网页 Markdown", "网页转 Markdown", "读取网页并总结", "这个链接帮我清洗一下".
