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 bobmatnyc/claude-mpm-skills at 718070a7d6.

    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

The better-auth-core skill provides a robust, production-ready authentication layer for AI applications. It handles secure user registration, login sessions, and password management without requiring complex custom implementations. This core module ensures your agents can verify identities safely before executing sensitive tasks.

When to use it

  • Rapid Prototyping: Integrate secure login flows into new AI projects in minutes instead of days.
  • Session Management: Maintain persistent user sessions across different AI agent interactions and API calls.
  • Multi-Provider Support: Enable users to authenticate via email/password or social providers like Google and GitHub.
  • Security Compliance: Enforce standard security practices for handling credentials and protecting user data in unstructured environments.

Key capabilities

  • Secure user registration and login logic
  • Session persistence and token management
  • Password hashing and verification
  • Social authentication integration (Google, GitHub)
  • Middleware for protected routes

Example prompts

  • "Initialize a secure authentication system for my new AI chatbot using better-auth-core."
  • "How do I configure session expiration for users accessing sensitive agent features?"
  • "Set up Google OAuth so my AI agent can verify user identity before processing payments."

Tips & gotchas

Ensure your backend environment has the necessary dependencies installed before attempting to initialize the auth server. While this skill handles core security, you must still configure environment variables for database connections and secret keys to prevent vulnerabilities in production deployments.
