Markdown.new

Use this skill to convert public URLs into LLM-ready Markdown via markdown.new.

Path Resolution (Critical)

• Resolve relative paths like scripts/... and references/... from the skill directory, not workspace root.
• If current directory is unknown, use an absolute script path.

python3 ~/.codex/skills/markdown-new/scripts/markdown_new_fetch.py 'https://example.com'

cd ~/.codex/skills/markdown-new
python3 scripts/markdown_new_fetch.py 'https://example.com'

Avoid this pattern from an arbitrary workspace root:

python3 scripts/markdown_new_fetch.py 'https://example.com'

Workflow

1. Validate the input URL is public http or https.
2. Run scripts/markdown_new_fetch.py with --method auto first.
3. Re-run with --method browser if output misses JS-rendered content.
4. Enable --retain-images only when image links are required.
5. Capture response metadata (x-markdown-tokens, x-rate-limit-remaining, and JSON metadata when present) for downstream planning.

Quick Start

Commands below assume current directory is the skill root (~/.codex/skills/markdown-new).

python3 scripts/markdown_new_fetch.py 'https://example.com' > page.md

python3 scripts/markdown_new_fetch.py 'https://example.com' --method browser --retain-images --output page.md

python3 scripts/markdown_new_fetch.py 'https://example.com' --deliver-md

Method Selection

• auto: default. Let markdown.new use its fastest successful pipeline.
• ai: force Workers AI HTML-to-Markdown conversion.
• browser: force headless browser rendering for JS-heavy pages.

Use auto first, then retry with browser only when needed.

Delivery Mode

• Use --deliver-md to force file output in .md format.
• In delivery mode, content is wrapped as:
  • <url>
  • ...markdown...
  • </url>
• If --output is omitted, the script auto-generates a filename from the URL.

API Modes

• Prefix mode:
  • https://markdown.new/https://example.com?method=browser&retain_images=true
• POST mode:
  • POST https://markdown.new/
  • JSON body: {"url":"https://example.com","method":"auto","retain_images":false}

Prefer POST mode for automation and explicit parameters.

Limits And Safety

• Treat 429 as rate limiting (documented limit: 500 requests/day/IP).
• Convert only publicly accessible pages.
• Respect robots.txt, terms of service, and copyright constraints.
• Do not treat markdown.new output as guaranteed complete for every page; verify critical extractions.
