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 rohitg00/awesome-claude-code-toolkit at ebdf1d596d.

    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 provides guidance and code examples for implementing various authentication patterns. It helps agents understand and apply common techniques like OAuth 2.0, JWT (JSON Web Tokens), and passwordless authentication to secure applications and APIs. The skill focuses on practical implementation details rather than abstract concepts.

When to use it

  • Integrating with third-party services: When your agent needs to access data or functionality from external platforms that require authentication.
  • Building a secure API: To ensure only authorized users can access and interact with an application's backend.
  • Implementing user registration and login flows: For creating robust and secure account management systems.
  • Modernizing legacy authentication: When refactoring older systems to use more contemporary and safer authentication methods.

Key capabilities

  • OAuth 2.0 implementation examples
  • JWT generation and verification guidance
  • Passwordless authentication strategies
  • Secure token storage recommendations

Example prompts

  • "Generate a Python script for authenticating with Google using OAuth 2.0."
  • "Show me an example of how to verify a JWT in Node.js."
  • "What are the best practices for storing refresh tokens securely?"

Tips & gotchas

This skill assumes some basic understanding of web development and security principles. Be mindful that implementing authentication correctly can be complex, and thorough testing is crucial to prevent vulnerabilities.
