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

What it does

This skill enables AI agents to handle secure user authentication using the better-auth library. It manages login sessions, token validation, and user identity verification across web applications.

When to use it

  • Implementing secure sign-in flows for new web projects requiring email or OAuth providers.
  • Managing session persistence and token refresh logic for long-running agent interactions.
  • Integrating existing better-auth instances into AI workflows that require protected endpoints.
  • Handling user registration and profile management within a trusted authentication framework.

Key capabilities

  • Seamless integration with the better-auth ecosystem for standardized security practices.
  • Support for multiple authentication providers including email/password and OAuth.
  • Automatic session management and secure token handling.
  • Centralized configuration for access control and user permissions.

Example prompts

  • "Set up a secure login page using better-auth for my new dashboard application."
  • "How do I configure OAuth2 authentication with Google using the better-auth skill?"
  • "Create a function to validate a user session token before granting API access."

Tips & gotchas

Ensure your backend environment has better-auth installed and configured before deploying agents relying on this skill. Always verify that environment variables for secrets (like database URLs or OAuth client IDs) are securely set, as the skill depends on proper initialization of the underlying library.
