create-auth

Scaffolds authentication into TypeScript/JavaScript apps using Better Auth. Detects your framework and database, configures adapters and route handlers, adds OAuth providers, and generates auth UI pages. Covers new projects, additions to existing codebases, and migrations from other auth libraries. Manually wiring Better Auth requires coordinating adapters, route handlers, CLI migrations, and client setup across multiple files — this skill handles the entire sequence in one guided flow, with framework-specific defaults pre-filled from your existing code.
