Install with the CLI

npx --yes palatekit@latest install nextjs15-supabase-security-rule

First time: connect the CLI with

npx --yes palatekit@latest login

Cursor applies 27 architecture rules: getUser() on the server instead of getSession(), awaiting params in Next.js 15, avoiding deprecated imports, enabling RLS and keeping Stripe keys server-side. The description says it also targets Claude Code.
