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.

  • Declares what it does: failed

    No SKILL.md was found in the skill's directory.

    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 sickn33/antigravity-awesome-skills at 5a4cdd9df8.

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

About this skill

What it does

The broken-authentication skill allows an AI agent to identify and exploit common authentication vulnerabilities. It can detect weaknesses like predictable session IDs, weak password policies, or insecure storage of credentials. This capability helps simulate attacks for security testing purposes and improve application resilience against unauthorized access.

When to use it

  • Penetration Testing: Simulate a malicious actor attempting to bypass authentication mechanisms on a web application.
  • Security Audits: Evaluate the strength of existing authentication systems by probing for common vulnerabilities.
  • Training & Education: Demonstrate real-world attack scenarios and educate developers about secure coding practices.
  • Vulnerability Research: Explore potential weaknesses in authentication protocols and identify novel attack vectors.

Key capabilities

  • Predictable Session ID Detection
  • Weak Password Policy Assessment
  • Insecure Credential Storage Identification

Example prompts

  • "Simulate an attacker attempting to brute-force the login credentials for example.com."
  • "Can you find any predictable session IDs on this website?"
  • "Assess the password policy strength of user registration page at target URL."

Tips & gotchas

The skill requires a clear understanding of authentication principles and potential vulnerabilities. It's crucial to use it responsibly and only within authorized testing environments, as unauthorized access attempts are illegal.
