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 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.target.com, crt.sh, target.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.

    Hosts contacted

  • 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 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.

About this skill

What it does

The security-reviewer skill enables AI agents to analyze code, configurations, and system setups for potential security vulnerabilities. It identifies common issues such as insecure dependencies, misconfigurations, and exposure of sensitive data. This tool helps ensure that applications and infrastructure are hardened against threats.

When to use it

  • Before deploying a new application to production to catch vulnerabilities early.
  • After updating third-party libraries or frameworks to check for newly introduced risks.
  • When reviewing pull requests or code changes for security compliance.
  • During routine audits of system configurations or cloud infrastructure setups.

Key capabilities

  • Scans codebases for known security flaws and best practices.
  • Detects insecure dependencies and outdated packages.
  • Identifies misconfigured environment variables and secrets exposure.
  • Provides actionable recommendations to mitigate risks.

Example prompts

  • "Review this Python script for potential security issues."
  • "Check the Dockerfile for vulnerabilities in base images or exposed ports."
  • "Analyze my AWS configuration files for insecure settings."

Tips & gotchas

  • Ensure that sensitive data such as API keys and passwords are not present in the code being reviewed.
  • The skill may require access to package repositories (e.g., npm, PyPI) to check dependency versions.
