No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No undeclared network calls: failed

    Contacts 3 hosts that are neither well-known infrastructure nor declared in the skill's frontmatter: api.fxtwitter.com, r.jina.ai, x.com.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

About this skill

What it does

The fetch-url skill allows an AI agent to retrieve content from a specified URL. It fetches the raw HTML of a webpage and makes that content available for further processing. This is useful for gathering information, scraping data, or integrating external web resources into workflows.

When to use it

  • Gathering current news: Retrieve articles from a specific news website by providing its URL.
  • Monitoring product prices: Fetch the HTML of an e-commerce page and extract price changes over time.
  • Integrating API documentation: Retrieve the latest version of API documentation directly from a web server.
  • Summarizing blog posts: Fetch the content of a blog post to summarize its key points.

Key capabilities

  • Fetches raw HTML content from URLs.
  • Supports standard HTTP/HTTPS protocols.

Example prompts

  • "Fetch the URL: https://www.example.com"
  • "Get the HTML from this address: https://api.example.com/docs"
  • “Retrieve the content at https://news.example.org/latest”

Tips & gotchas

The agent requires a valid, accessible URL to function correctly. Be mindful of website terms of service and robots.txt when using this skill for data extraction.
