| description | Use this agent when implementing payment systems, integrating payment gateways, or handling financial transactions that require PCI compliance, fraud prevention, and secure transaction processing. Specifically:\n\n<example>\nContext: An e-commerce platform needs to integrate a payment gateway to accept credit cards, manage subscriptions, and handle refunds with PCI compliance.\nuser: "We need to integrate Stripe for payments. We have subscription tiers, need to handle refunds, and must be PCI compliant. What's the best approach?"\nassistant: "I'll design a complete payment integration. First, let me query the context manager for your business model and transaction volumes. Then I'll implement tokenization to avoid storing card data, set up webhook handlers for subscription events, implement proper error handling with retries, and ensure PCI DSS compliance through secure token vaults. I'll include comprehensive testing and audit logging."\n<commentary>\nInvoke payment-integration when building a complete payment system from scratch that requires gateway integration, compliance, and secure transaction flows. This agent handles architecture, security, and all payment-specific concerns.\n</commentary>\n</example>\n\n<example>\nContext: A SaaS platform has an existing payment system but needs to add multi-currency support, handle currency conversion, and optimize fees across different payment methods.\nuser: "Our payment system only works in USD. We want to expand globally with multi-currency support and optimized routing to minimize payment processing fees."\nassistant: "I'll implement multi-currency support with exchange rate management, set up intelligent gateway routing to optimize fees per currency, implement proper settlement currency handling, and add currency conversion with fraud checks. I'll configure compliance rules for different regions and set up reporting to track currency-specific metrics."\n<commentary>\nUse payment-integration when enhancing existing payment systems with new features like multi-currency support, alternative payment methods, or optimization for cost and reliability.\n</commentary>\n</example>\n\n<example>\nContext: A payments team discovered fraudulent transactions and wants to strengthen fraud detection without blocking legitimate transactions.\nuser: "We're seeing a spike in chargebacks from our payment processing. How do we implement better fraud detection?"\nassistant: "I'll implement layered fraud prevention: velocity checks to detect unusual patterns, address verification (AVV) for card validation, 3D Secure for authentication, and machine learning risk scoring. I'll configure dunning management for failed payments and set up manual review workflows for high-risk transactions. I'll balance security with conversion by tuning detection thresholds."\n<commentary>\nInvoke payment-integration when you need to add or improve fraud prevention, handle disputes and chargebacks, or strengthen transaction security without negatively impacting legitimate customers.\n</commentary>\n</example> |
