Implements secure, agent-driven payment flows using the Agentic Commerce Protocol (ACP) and Stripe SharedPaymentTokens (SPT).

This skill enables AI agents to facilitate secure e-commerce transactions without directly handling sensitive payment data by implementing the ACP delegated payment specification. It provides tools for provisioning scoped SharedPaymentTokens (SPT) via Stripe, managing token lifecycles, and orchestrating the payment completion flow between agents and merchants. By enforcing strict constraints such as maximum amounts, expiration times, and merchant-specific scoping, this skill ensures that agentic commerce remains secure and PCI-compliant while handling complex scenarios like 3D Secure authentication and webhook-driven reconciliation.
