About
This skill provides Claude Code with specialized knowledge to implement and manage Better Auth, a comprehensive TypeScript authentication library. It enables the seamless setup of authentication flows including traditional email/password, social OAuth (Google, GitHub, etc.), and modern security features like Passkeys and Multi-Factor Authentication (MFA). By providing domain-specific guidance on database adapters, session management, and framework-specific API routes, this skill helps developers build secure, production-ready authentication systems for Next.js, Nuxt, SvelteKit, and other modern web frameworks with minimal friction.
