Better Auth

The better-auth skill integrates the better-auth library into AI agent workflows to handle secure user authentication. It enables agents to manage login sessions, verify identities, and protect application endpoints using industry-standard security practices. This tool is essential for building trustworthy applications where user data privacy and access control are critical.

When to use it

• Implementing secure sign-in flows (email/password, OAuth) for AI-powered web applications.
• Protecting sensitive API endpoints that require user verification before execution.
• Managing session persistence and token refresh logic within autonomous agent loops.
• Enforcing role-based access control (RBAC) to restrict agent capabilities based on user permissions.

Key capabilities

• Provides a robust authentication layer with support for multiple providers (Google, GitHub, etc.).
• Handles secure cookie management and session validation automatically.
• Offers built-in middleware to protect routes from unauthorized access.
• Simplifies the integration of complex auth logic into AI agent codebases.

Example prompts

• "Set up a secure login system using better-auth for my new AI dashboard."
• "How do I configure OAuth providers with better-auth to allow users to log in via Google?"
• "Create a protected route that requires user authentication before the AI agent can access data."

Tips & gotchas

Ensure your backend environment variables (like database URLs and secret keys) are properly configured before initializing the auth instance. Always validate tokens on the server side, even if client-side checks are in place, to prevent session hijacking.
