I built markdown.new
Put markdown.new/ before any URL → get clean Markdown back.
Cloudflare's Markdown for Agents is great, but only works for enabled sites. markdown.new works for ANY website on the internet.
80% fewer tokens. Also converts PDFs, images, audio.
Free. No signup.
markdown.new
Time to consider not just human visitors, but to treat agents as first-class citizens. Cloudflare’s network now supports real-time content conversion to Markdown at the source using content negotiation headers.

Opus 5.5’s own system prompt:
“Fetches a URL, converts to markdown, and answers prompt against it using a small fast model.”
That’s a summary. Not the page.
For full content you may use → markdown.new/ + URL 📄
🚰 SYSTEM PROMPT LEAK 🚰
Here's the full system prompt for Claude Opus-5.5!! The total count of everything extracted, including all tools, comes in at over 1.9M characters! 🤯
Lots to dig into here. Enjoy! 🫡

Ahrefs to Enterprise: “Here’s the world.”
Ahrefs to everyone else: “Here’s the dropdown. Use it 40 times.”
The feature: All Locations. 😅
The fine print: One location only. Enterprise.
Google wants users to stay on Google instead of clicking through to other sites. That’s a dead end for publishers and content creators.
I don’t think we get an AI Mode-default era without the blue links.
Google is removing the "Show more" button from AI Overviews, making it more like AI Mode by default - this is not great for publishers seroundtable.com/google-ai-o… via @chris_nectiv
No matter how explicitly clear your prompt is, sometimes an LLM just goes full Baby Groot. #happysunday
