Claude-skill-registry crawl-to-markdown

Use this skill only after the built-in

web.run

tool fails to return usable content for a page.

What this skill does

• Crawls one or more URLs with Crawl4AI.
• Returns raw Markdown for each URL.

How to run

This script uses uv inline metadata. If

uv

is available just run:

uv run scripts/crawl_to_markdown.py https://example.com

Multiple URLs:

uv run scripts/crawl_to_markdown.py https://example.com https://example.org

Or pipe a newline-delimited list:

printf "https://example.com\nhttps://example.org\n" | uv run scripts/crawl_to_markdown.py

Troubleshooting

Crawl succeeds but output is blank

Some sites don't match the default

--selector

and can return empty/whitespace Markdown. The script will retry without CSS selection automatically, but you can also force it explicitly:

uv run scripts/crawl_to_markdown.py --selector '' https://example.com

uv cache permission errors

If

uv

fails accessing its cache directory (e.g.

~/.cache/uv

), either point it at a writable cache directory:

uv --cache-dir .uv-cache run scripts/crawl_to_markdown.py https://example.com

Or avoid the cache entirely:

uv --no-cache run scripts/crawl_to_markdown.py https://example.com

Output format

For each URL, the script prints a header and raw Markdown content:

URL: https://example.com
<raw markdown>
---

If a crawl fails, the output includes an error block for that URL.
