Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install better-auth-typescript-setup

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent applies 42 rules ranked by impact: auth instance, database adapter, route handlers, session cookies, OAuth, email verification and plugins. You get authentication configured to Better Auth guidance, with migration from NextAuth, Clerk, Auth0 or Supabase Auth if needed.
