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 jeffallan/claude-skills at 1be15d8064.

    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

The fullstack-guardian skill provides comprehensive monitoring and protection for full-stack applications, ensuring security, performance, and reliability across both front-end and back-end components. It includes features like real-time error tracking, automated vulnerability scanning, and performance optimization suggestions.

When to use it

  • When deploying a new full-stack application to ensure it is secure from the start.
  • During routine maintenance to detect and resolve potential issues before they impact users.
  • After updating dependencies or integrating third-party services to check for compatibility and security risks.
  • To continuously monitor application health in production environments.

Key capabilities

  • Real-time error detection and logging
  • Automated vulnerability scanning for known exploits
  • Performance optimization recommendations
  • Integration with CI/CD pipelines for automated testing
  • Alerting system for critical issues

Example prompts

  • "Scan my full-stack app for security vulnerabilities."
  • "Monitor the performance of my web application in real time."
  • "Provide a report on potential bottlenecks in my backend services."

Tips & gotchas

  • Ensure your application is fully deployed and accessible before running scans.
  • Some advanced features may require additional configuration or integration with external tools.
