This skill is a disclosed PowPow account-registration and optional payment assistant; it handles credentials and checkout flow, but the behavior is coherent with its stated purpose.
Install only if you trust PowPow and are comfortable letting the agent help create an account using your email, verification code, optional avatar, and password passed via environment variable. For payment, the agent should only create/open the checkout and poll status; you should complete payment yourself and verify the browser is on an official Alipay or PayPal page. Run cleanup at the end to remove the temporary token state.
