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 secondsky/claude-skills at 8837836131.

    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

The better-auth skill enables AI agents to manage user authentication and session handling within applications. It provides a robust framework for securing access by verifying identities and maintaining secure login states.

When to use it

  • Implementing secure sign-up and sign-in flows for new user registration.
  • Managing persistent user sessions across different application environments.
  • Enforcing access control policies based on verified user credentials.
  • Integrating third-party authentication providers into existing systems.

Key capabilities

  • Comprehensive authentication management for AI-driven applications.
  • Session handling and state verification mechanisms.
  • Secure identity verification protocols.
  • Support for diverse login scenarios within the secondsky/claude-skills ecosystem.

Example prompts

  • "Set up a secure user registration flow using better-auth for my new project."
  • "How can I implement session management with better-auth to protect user data?"
  • "Integrate third-party login options into my application using the better-auth skill."

Tips & gotchas

Ensure your application environment supports the specific authentication protocols required by better-auth. Always verify that session tokens are stored securely to prevent unauthorized access.
