Claude Code built it with stripe

Prompt: Add billing to this SaaS: a pricing page, hosted checkout, and a customer portal link.

Grader: The agent installed stripe, wired a pricing page, hosted subscription Checkout, a customer portal route and a signed webhook handler, and the build, lint and typecheck passed. It could not run a live checkout without Stripe keys, which it disclosed, and it hit a pnpm ignored-build error during install that did not block the result.
