rclone_copyurl

rclone_copyurl is a command for coding agents from chaunsin/agent-skills. It costs 12 tokens per session (804 once invoked), scanned A, a copy of rclone_copyurl, Apache-2.0.

A command that downloads content directly from a web address into a destination managed by rclone, without first saving a temporary local copy.

In plain words
What is it for?
Use it to copy one URL, or a CSV list of URLs and filenames, to a remote path; print the content to standard output; and choose filenames automatically or from HTTP headers.
Why use it?
It avoids a separate download-and-upload step when moving web content to cloud or other storage. It can also prevent overwriting an existing destination file.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

rclone_copyurl scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Official documentation: https://rclone.org/commands/rclone_copyurl/

rclone copyurl

Copy the contents of the URL supplied content to dest:path.

Synopsis

Download a URL's content and copy it to the destination without saving it in temporary storage.

Setting --auto-filename will attempt to automatically determine the filename from the URL (after any redirections) and used in the destination path.

With --header-filename in addition, if a specific filename is set in HTTP headers, it will be used instead of the name from the URL. With --print-filename in addition, the resulting file name will be printed.

Setting --no-clobber will prevent overwriting file on the destination if there is one with the same name.

Setting --stdout or making the output file name - will cause the output to be written to standard output.

Setting --urls allows you to input a CSV file of URLs in format: URL, FILENAME. If --urls is in use then replace the URL in the arguments with the file containing the URLs, e.g.:

rclone copyurl --urls myurls.csv remote:dir

Missing filenames will be autogenerated equivalent to using --auto-filename. Note that --stdout and --print-filename are incompatible with --urls. This will do --transfers copies in parallel. Note that if --auto-filename is desired for all URLs then a file with only URLs and no filename can be used.

Troubleshooting

If you can't get rclone copyurl to work then here are some things you can try:

  • --disable-http2 rclone will use HTTP2 if available - try disabling it
  • --bind 0.0.0.0 rclone will use IPv6 if available - try disabling it
  • --bind ::0 to disable IPv4
  • --user agent curl - some sites have whitelists for curl's user-agent - try that
  • Make sure the site works with curl directly
rclone copyurl https://example.com dest:path [flags]

Options

  -a, --auto-filename     Get the file name from the URL and use it for destination file path
      --header-filename   Get the file name from the Content-Disposition header
  -h, --help              help for copyurl
      --no-clobber        Prevent overwriting file with same name
  -p, --print-filename    Print the resulting name from --auto-filename
      --stdout            Write the output to stdout rather than a file
      --urls              Use a CSV file of links to process multiple URLs

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
