better-auth

What it does

This skill integrates the better-auth library into AI agent workflows to handle secure authentication and session management. It enables agents to verify user identities, manage login states, and protect application endpoints with industry-standard security practices.

When to use it

• Securing API Endpoints: Protecting sensitive routes that require user verification before processing requests.
• User Session Management: Handling login, logout, and session persistence for multi-step agent interactions.
• OAuth Integration: Implementing third-party authentication flows like Google or GitHub for easier user onboarding.
• Role-Based Access Control: Restricting specific agent capabilities based on authenticated user roles or permissions.

Key capabilities

• Unified authentication logic across different platforms and frameworks.
• Built-in support for social logins (OAuth providers).
• Automatic session token generation and validation.
• Middleware hooks for intercepting and validating requests before execution.

Example prompts

• "Set up a secure login flow using better-auth so the agent can verify my identity before accessing my project files."
• "Configure OAuth authentication with Google to allow users to sign in directly via the agent interface."
• "Implement session management logic that expires user tokens after 30 minutes of inactivity for security compliance."

Tips & gotchas

Ensure your backend environment is properly configured with a valid secret key before initializing the better-auth instance, as this is critical for token signing. Be mindful of rate limiting settings to prevent brute-force attacks on authentication endpoints.
