web-to-markdown

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.

Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
8 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by rookie-ricardo on GitHub. Read the source before you install it.

Installation

Install the Web To Markdown AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/rookie-ricardo/erduo-skills/tree/main/skills/web-to-markdown
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/rookie-ricardo/erduo-skills.git /tmp/erduo-skills
mkdir -p .claude/skills
cp -r /tmp/erduo-skills/skills/web-to-markdown .claude/skills/web-to-markdown

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Web To Markdown in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Web To Markdown on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Web To Markdown is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Web To Markdown

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

Quick Workflow

Normalize and validate the input URL.
Select route:

r.jina.ai: general web + X/Twitter.
defuddle.md: YouTube transcript/content extraction.
special-browser-fetch: WeChat/Zhihu/Feishu.

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):

bash
npm install
node scripts/url_to_markdown.mjs <url>

Return metadata with markdown:

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

Force special-site browser extraction:

bash
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/fetch_special_sites.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:

Try cuimp HTTP/TLS impersonation first, then clean HTML with Mozilla Readability.
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.

scripts/url_to_markdown.mjs: primary entrypoint.
scripts/fetch_special_sites_http.mjs: WeChat/Zhihu/Feishu HTTP impersonation fetcher (cuimp JS).
scripts/fetch_special_sites.mjs: two-stage extractor (HTTP-first, browser-fallback).

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Web To Markdown AI skill do?

Why use Web To Markdown on TypingMind?

Because you install it once and use it with any model. Web To Markdown is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Web To Markdown in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/rookie-ricardo/erduo-skills/tree/main/skills/web-to-markdown. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Web To Markdown?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Web To Markdown?

As many as you like. As long as a model supports skills, you can use Web To Markdown with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Web To Markdown AI skill free?

Yes. It is published on GitHub by rookie-ricardo under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
