Not pinned. Installing fetches whatever the repository holds at the time you run the command.

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 passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    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 obfuscated payloads: passed

    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

    Scanned jwynia/agent-skills at e02ec7e226.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

scraper-builder

What it does

This skill enables AI agents to construct custom web scrapers directly from natural language instructions. It automates the process of building tools to extract specific data from websites without requiring manual coding or configuration.

When to use it

  • You need to gather structured data (like prices, articles, or contact info) from a public website quickly.
  • Your agent requires a reusable tool to monitor changes on a site over time.
  • You want to bypass the need for manual browser automation setup for one-off data extraction tasks.

Key capabilities

  • Generates functional web scraper code based on user prompts.
  • Configures scraping logic to target specific elements or patterns on a page.
  • Outputs ready-to-use scripts that can be executed by the agent's environment.

Example prompts

  • "Build a scraper to extract all product titles and prices from this e-commerce homepage."
  • "Create a tool that scrapes recent blog posts and their publication dates from a news site."
  • "Write a script to collect email addresses listed in the contact section of multiple company websites."

Tips & gotchas

Ensure the target website allows automated scraping by checking its robots.txt file and terms of service to avoid legal issues. Be mindful of rate limits; if the scraper fails repeatedly, add delays between requests to prevent being blocked.
