Add-ons via skills.sh

Vendor skills stay current. This repo only maps them onto db/schema.ts.

npx skills add vercel/ai@ai-sdk

AI chat

Not in package.json until you ask. Gate it behind the existing session.

npx skills add stripe/ai@stripe-best-practices

Stripe

subscriptions table is already here. Checkout is an add-on.
