markdown.new URL Prefix

Whenever you need to visit a website URL, you must:

  1. rewrite it to go through https://markdown.new/, then
  2. visit the rewritten URL, and
  3. pull the Markdown content from that page for use in your answer/notes.

Rewrite Rule

  1. Normalize the destination into an absolute URL with a scheme (https:// preferred).
  2. Prefix it with https://markdown.new/ (do not drop the original scheme).

Examples

  • https://example.com -> https://markdown.new/https://example.com
  • https://example.com/docs?a=1#b -> https://markdown.new/https://example.com/docs?a=1#b
  • example.com -> https://markdown.new/https://example.com

Agent Workflow (Required)

When you would normally open a website to read it:

  1. Produce the rewritten markdown.new URL.
  2. Visit the rewritten URL first (not the original), but only when it is likely to work (see Policy below).
  3. Extract the page content from the Markdown view (the rendered Markdown and/or the raw Markdown).
  4. Use that extracted Markdown as the source for summaries, quotes, checklists, or copy/pasteable notes.

If the markdown.new view fails to load or breaks critical functionality, fall back to the original URL for browsing, but still prefer markdown.new for any content extraction if possible.

Policy: When To Use markdown.new (Required)

Do NOT route every site through markdown.new. Use it primarily for "read-only" pages where you want clean, extractable text:

  • Documentation pages
  • Blog posts / announcements / changelogs
  • GitHub issues/PR discussions (when you just need readable text)
  • Articles and guides

Skip markdown.new and go straight to the original URL when the destination is likely to be blocked or requires the original site behavior:

  • Login, OAuth, checkout, payment, or any authenticated workflow
  • Sites that gate content behind JS apps, CAPTCHAs, bot detection, or paywalls
  • File uploads, forms, editors, dashboards, interactive widgets
  • Anything where cookies/session state must be preserved

Block/Failure Signals (Treat As Blocked)

If you try markdown.new and see any of the below, stop retrying and fall back to the original URL:

  • HTTP 401/403/429, "Access denied", "Forbidden", "rate limited"
  • CAPTCHA / "verify you are human"
  • Empty/partial content that clearly does not match the page
  • Redirect loops or repeated navigation failures

Fallback Behavior

  1. Attempt markdown.new once when appropriate.
  2. On block/failure, immediately switch to the original URL for browsing.
  3. If you still need extractable text, try to extract from the original page (reader mode / copy text) and clearly note that markdown.new was blocked.

Notes / Exceptions

  • Keep this for reading/browsing. For API endpoints, OAuth flows, file uploads, or anything that depends on cookies/login state, use the original URL if the proxy breaks functionality.
  • Do not rewrite local paths (./README.md) or non-HTTP(S) schemes.

Optional CLI Helper

Convert a URL into its markdown.new-prefixed form:

node skills/markdown-url/scripts/markdown-url.js "https://example.com/docs"

Frequently asked

When should I use markdown.new instead of visiting the original URL?
Use markdown.new for read-only pages like documentation, blog posts, changelogs, and GitHub issues where you need clean, extractable text. Skip it for authenticated workflows, login pages, paywalled content, or interactive features that require the original site behavior.
What do I do if markdown.new fails to load or returns an error?
If you encounter HTTP 401/403/429, CAPTCHAs, empty content, or redirect loops, immediately fall back to the original URL. Try to extract text from the original page directly if you still need content.
How do I rewrite a URL to use markdown.new?
Prefix the absolute URL with `https://markdown.new/`. For example, `https://example.com/docs` becomes `https://markdown.new/https://example.com/docs`. Keep the original scheme and all query parameters and fragments.
Does this work with local file paths or non-HTTP URLs?
No. Do not rewrite local paths like `./README.md` or non-HTTP(S) schemes. Use markdown.new only for absolute URLs with http or https.
