pci-dss-rails

What problem does it solve?

Rails applications that accept credit or debit card payments risk costly PCI-DSS violations, expensive full-scope audits, and data breaches if they accidentally handle, store, or log sensitive cardholder data like full card numbers (PAN) or CVV codes. This skill eliminates that risk by enforcing industry-standard compliant payment patterns.

Core Features & Use Cases

• Minimal PCI Scope Enforcement: Guides implementation of Stripe Elements, Braintree Hosted Fields, or Stripe Checkout to keep all card data off your servers, reducing PCI audit scope to the lightest SAQ-A level.
• Card Data Protection Rules: Explicitly prohibits storing, logging, or transmitting sensitive card data, with concrete examples for filtering card fields from Rails logs and error tracking tools like Sentry.
• Compliant Payment Workflows: Provides production-ready patterns for payment intent creation, saved card tokenization, EU/UK SCA/3DS2 handling, and Stripe webhook integration that never exposes full card data. Use case: A Rails e-commerce team adding card payments can use this skill to implement a compliant checkout flow, avoid accidental PAN logging, and pass PCI audits without expanding their compliance burden.

Quick Start

Use the pci-dss-rails skill to implement a Stripe Elements checkout flow that keeps all card data off your Rails servers and maintains SAQ-A PCI compliance.
