Clerk Billing skill: what it does and how to install it

What it does. Configures Clerk Billing for user and organisation subscriptions by enabling billing, defining plans and features, rendering PricingTable and checkout UI, and checking entitlements with has(). It covers seat-limited B2B plans, subscription status, verified Clerk webhooks, and CLI-based billing configuration.

When to use it. Use it when implementing SaaS pricing, trials, plan or feature access, checkout, invoicing or subscription lifecycle handling in a Clerk app. It does not treat Stripe as the plan catalogue; Clerk stores plans, while production payment processing requires Stripe.
