Live repository

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 ballred/obsidian-claude-pkm at ef1e4da2f3.

    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

What it does

This skill, check-links, verifies the validity of URLs within a given text. It can determine if links are broken or redirecting unexpectedly and provide feedback on their status. The tool is designed to improve content quality by ensuring all external references remain functional.

When to use it

  • Content Audits: Before publishing articles or blog posts, verify that all linked resources are still accessible.
  • Website Maintenance: Regularly check internal and external links on a website for broken connections.
  • Research Validation: Confirm the accuracy of sources cited in research papers or reports.
  • Knowledge Base Updates: Ensure links within documentation or help articles remain valid as websites evolve.

Key capabilities

  • URL validation
  • Broken link detection
  • Redirect status reporting

Example prompts

  • "Check these links: [list of URLs]"
  • "Verify the validity of all URLs in this document."
  • "Are any of these links broken? [text containing URLs]"

Tips & gotchas

The skill's accuracy depends on network connectivity; intermittent issues may affect results. It is best used with a stable internet connection for reliable link verification.
