Summary

  • Convert a web URL into cleaned Markdown with deterministic routing.
  • Use when Codex needs to read article-like content from links and should apply source-aware fetch strategies: default to r.jina.ai for general pages (including X/Twitter), use defuddle.md for YouTube links, and use browser-impersonated extraction for WeChat/Zhihu/Feishu pages with Mozilla Readability cleanup.

Web To Markdown

Convert URLs into usable Markdown by applying domain-aware fetching routes, then return the cleaned content directly.

Quick Workflow

  1. Normalize and validate the input URL.
  2. Select route:
  • r.jina.ai: general web + X/Twitter.
  • defuddle.md: YouTube transcript/content extraction.
  • special-browser-fetch: WeChat/Zhihu/Feishu.
  1. Return markdown text (or JSON metadata if needed).

For generic URLs (non-YouTube, non-WeChat/Zhihu/Feishu), use this fallback chain:

  • try r.jina.ai first,
  • if it fails, fallback to direct HTTP fetch + Readability,
  • if direct fetch still fails or returns shell-like content, fallback to browser extraction.

Commands

Run from this skill directory (skills/web-to-markdown):

npm install
node scripts/url_to_markdown.mjs <url>

Return metadata with markdown:

node scripts/url_to_markdown.mjs <url> --json

Force special-site browser extraction:

node scripts/fetch_special_sites.mjs <url> --json

Routing Policy

  • Default route: https://r.jina.ai/<url>.
  • YouTube (youtube.com, youtu.be): https://defuddle.md/<url>.
  • X/Twitter (x.com, twitter.com): https://r.jina.ai/<url>.
  • WeChat/Zhihu/Feishu: run scripts/fetchspecialsites.mjs.
  • If input is already proxy-formatted (https://defuddle.md/https://... or https://r.jina.ai/https://...), normalize back to the original URL and re-apply routing.

Special-Site Extraction Behavior

Use a two-stage strategy for WeChat/Zhihu/Feishu:

  1. Try cuimp HTTP/TLS impersonation first, then clean HTML with Mozilla Readability.
  2. If stage 1 fails or returns blocked/shell content, fallback to puppeteer-extra browser impersonation.
  • HTTP stage impersonates modern Chrome TLS/HTTP profile via cuimp.
  • Browser stage impersonates a modern Chrome user agent and standard sec-ch-ua headers.
  • Remove known login modals and backdrop overlays (best effort).
  • Scroll the page to trigger lazy-loaded article blocks.
  • Parse cleaned document with Mozilla Readability.
  • Convert extracted HTML body to Markdown via Turndown.
  • Resolve browser executable from CHROME_PATH first, then system Chrome/Chromium/Edge paths.

If special-site extraction fails due to anti-bot checks, account-only pages, or network limits, report failure clearly and ask for fallback input (for example raw page text).

Output Contract

For normal usage, output markdown only.

When --json is used, return:

  • source: backend source (r.jina.ai, defuddle, cuimp, browser-readability).
  • strategy: selected route (r-jina, defuddle, special-http-fetch, special-browser-fetch-fallback).
  • requestedUrl: original input.
  • resolvedUrl: normalized/final URL.
  • markdown: extracted markdown body.
