Markdown Proxy URL to Markdown 将任意 URL 转为干净的 Markdown。支持需要登录的页面、PDF、专有平台。 Trigger Priority（先触发，再分流）用户给出 URL 并要求“读取、抓取、提取、解析、转 Markdown”时，优先使用本 Skill。用户要求“读取这篇链接后再写稿、总结、翻译、做播客或分析”时，先用本 Skill 取回原文，再把 Markdown 交给下游 Skill；不要因为最终任务是写作而跳过抓取。 mp.weixin.qq.com 和飞书文档属于专用路由。不要先试普通网页打开或通用内容解析器。用户已经贴出全文时不触发。YouTube 交给 qiaomu youtube download ，普通搜索问题交给搜索工具。 URL Routing (先判断再执行) 收到 URL 后，先判断类型，不同类型走不同通道： URL Pattern Route To Reason mp.weixin.qq.com scripts/fetch weixin.sh 先代理，验证码页自动回退 Playwright feishu.cn/docx/ feishu.cn/wiki/ larksuite.com/docx/ scripts/fetch feishu.py 需飞书 API 认证 youtube.com youtu.be qiaomu youtube download skill YouTube 有专用工具链 huggingface.co/papers/ 提取 arXiv ID → scripts/extract tex.py HuggingFace 论文页实际是 arXiv 镜像，先找到 arXiv 链接再走 LaTeX 提取 arxiv.org/abs/ arxiv.org/pdf/ scripts/extract tex.py 从 LaTeX 源码提取结构化内容 (章节/图表/公式) .pdf (URL or local path) scripts/extract pdf.sh PDF 专用提取 All other URLs scripts/fetch.sh 代理级联自动 fallback Workflow Step 1: Route by URL Type Step 2: Display Content After fetching, show to user: Step 3: Continue or Save Composite request （“读取后写稿/总结/分析”）：把提取结果直接交给下游任务，在同一轮继续；除非用户要求，不必额外保存源文件。 Extraction only request （“只读取/转 Markdown”）：保存到 ~/Downloads/{title}.md ，使用 YAML frontmatter。 Filename: use article title, remove special characters. Format: YAML frontmatter (title, author, date, url, source) + Markdown body. Tell the user the saved path. Skip saving if the user says “just preview” or “don't save”. Only stop after extraction when extraction was the complete request. If the user asked for a downstream deliverable, continue to that deliverable. Examples General URL X/Twitter Post WeChat Article Feishu Document arXiv LaTeX Source PDF (Remote) PDF (Local) With Custom Proxy Notes r.jina.ai and defuddle.md require no API key fetch.sh handles proxy cascade with automatic fallback Content validation: filters error, login wall, and WeChat verification pages; requires 5 lines WeChat wrapper prefers dependency free proxies, then uses local Playwright; when Python packages are missing and uv is available, it runs them in an isolated environment Playwright fallback requires a Chromium runtime; install once with python3 m playwright install chromium if absent Feishu script requires: FEISHU APP ID + FEISHU APP SECRET env vars PDF extraction tries: marker pdf → pdftotext → pypdf For detailed method documentation, see references/methods.md
