qiaomu-markdown-proxy

name	qiaomu-markdown-proxy
description	Read, fetch, extract, parse, or convert a URL or link into clean Markdown. Use FIRST whenever a user asks to read source content from a webpage, especially WeChat/微信公众号 mp.weixin.qq.com, Feishu/Lark docs, X/Twitter, PDFs, arXiv papers, or a URL that will feed a later summary, rewrite, article, podcast, or analysis. For WeChat and Feishu, prefer this specialist extractor over generic web open or generic content parsers. Exclude YouTube, pure web search, already-pasted text, and local non-PDF files.

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

if URL contains "mp.weixin.qq.com":
    → bash ~/.agents/skills/qiaomu-markdown-proxy/scripts/fetch_weixin.sh "URL"
    → Done

if URL contains "feishu.cn/docx/" or "feishu.cn/wiki/" or "larksuite.com/docx/":
    → python3 ~/.agents/skills/qiaomu-markdown-proxy/scripts/fetch_feishu.py "URL"
    → Done

if URL contains "huggingface.co/papers/":
    → First fetch the page (WebFetch) to find the arXiv URL
    → Then python3 ~/.agents/skills/qiaomu-markdown-proxy/scripts/extract_tex.py "{arxiv_url}"
    → Done

if URL contains "arxiv.org/abs/" or "arxiv.org/pdf/":
    → python3 ~/.agents/skills/qiaomu-markdown-proxy/scripts/extract_tex.py "URL"
    → Done

if URL contains "youtube.com" or "youtu.be":
    → Call qiaomu-youtube-download skill
    → Done

if URL ends with ".pdf" or is local PDF path:
    if remote URL:
        → Try: curl -sL "https://r.jina.ai/{url}"
        → If fails: download + extract_pdf.sh
    if local path:
        → bash ~/.agents/skills/qiaomu-markdown-proxy/scripts/extract_pdf.sh "PATH"
    → Done

else:
    → bash ~/.agents/skills/qiaomu-markdown-proxy/scripts/fetch.sh "URL"
    → Done

Step 2: Display Content

After fetching, show to user:

Title:  {title}
Author: {author} (if available)
Source: {platform} (公众号 / 飞书文档 / 网页 / PDF)
URL:    {original_url}

Summary
{3-5 sentence summary}

Content
{full Markdown, truncated at 200 lines if long}

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

bash ~/.agents/skills/qiaomu-markdown-proxy/scripts/fetch.sh "https://example.com/article"

X/Twitter Post

bash ~/.agents/skills/qiaomu-markdown-proxy/scripts/fetch.sh "https://x.com/username/status/1234567890"

WeChat Article

bash ~/.agents/skills/qiaomu-markdown-proxy/scripts/fetch_weixin.sh "https://mp.weixin.qq.com/s/abc123"

Feishu Document

python3 ~/.agents/skills/qiaomu-markdown-proxy/scripts/fetch_feishu.py "https://xxx.feishu.cn/docx/xxxxxxxx"

arXiv LaTeX Source

python3 ~/.agents/skills/qiaomu-markdown-proxy/scripts/extract_tex.py "https://arxiv.org/abs/1706.03762"

PDF (Remote)

curl -sL "https://r.jina.ai/https://example.com/paper.pdf"

PDF (Local)

bash ~/.agents/skills/qiaomu-markdown-proxy/scripts/extract_pdf.sh "/path/to/paper.pdf"

With Custom Proxy

bash ~/.agents/skills/qiaomu-markdown-proxy/scripts/fetch.sh "https://example.com" "http://127.0.0.1:7890"

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
