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

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 zxhfighter/skills-hub at ac33458514.

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

About this skill

What it does

This skill checks Markdown text for syntax errors and potential formatting issues. It identifies problems like incorrect indentation, unclosed brackets, or misused Markdown elements. The tool aims to improve readability and ensure consistent formatting of documents written in Markdown.

When to use it

  • Blog Post Editing: Before publishing a blog post, use the skill to catch any Markdown errors that might render incorrectly on the live site.
  • Documentation Review: Ensure technical documentation adheres to established Markdown style guidelines.
  • Note-Taking Consistency: Maintain consistent formatting across notes and documents created using Markdown.
  • Collaborative Writing: When multiple people contribute to a Markdown document, use this skill to ensure everyone is following the same conventions.

Key capabilities

  • Markdown syntax error detection
  • Formatting issue identification
  • Style guideline enforcement (implied)

Example prompts

  • "Check this Markdown for errors: [paste markdown text here]"
  • "Can you validate this document's Markdown formatting? [paste markdown text here]"
  • “Find any syntax issues in the following: [paste markdown text here]”

Tips & gotchas

The skill’s effectiveness depends on a clear understanding of Markdown conventions. While it identifies errors, it may not always suggest the best fix – review suggestions carefully.
