How does it verify that payments are actually working?

It performs a full test cycle: creating a checkout session, completing it with a test card, verifying webhook receipt, and confirming database updates.

What happens during the audit phase?

The skill runs automated scripts to check environment variable parity, webhook endpoint health, security vulnerabilities like hardcoded keys, and compliance with subscription logic best practices.

Can it automatically create a billing UI?

Yes, if subscription management UX is missing, the skill can implement settings pages, plan displays, and Stripe Customer Portal integrations.

Does it handle Stripe webhooks specifically?

Yes, it verifies that endpoints are registered, return non-redirect status codes, and have zero pending events in the Stripe Dashboard.

Which tech stacks are supported?

While optimized for Next.js, TypeScript, and Convex, the skill's logic is framework-agnostic and adapts to most modern web development stacks.
