    About this skill

    The problem

    Integrating payments manually is error-prone and carries significant security risks. Developers often struggle with webhook boilerplate, secret management, and aligning Stripe flows with existing framework conventions.

    What it does

    • Detects your framework and routing patterns to inject Stripe integration that matches your code style.
    • Generates Stripe Checkout sessions and subscription flows using official SDKs.
    • Sets up secure webhook handlers with signature verification and event processing.
    • Automates environment variable scaffolding and dependency management without hardcoding secrets.
    • Creates or updates test suites to ensure payment routes and handlers function correctly.

    Frameworks & tools

    Works with any project utilizing the Stripe Node.js or Python SDKs. Adapts to existing web frameworks like Express, Next.js, FastAPI, or Django.

    Why this beats prompting it yourself

    General prompts often lead to hardcoded keys or insecure custom card handling. This skill enforces a security-first architecture, strictly using environment variables and Stripe-hosted Checkout to minimize PCI compliance burden while matching your specific project structure.

    Use cases

    • Adding a subscription billing flow to a SaaS boilerplate.
    • Implementing a one-time checkout for an e-commerce product page.
    • Setting up webhook listeners to sync payment status with your database.
    • Refactoring insecure legacy payment code to use modern Stripe best practices.

    Known limitations

    Does not support custom payment UI components or direct card data handling to ensure security. It will not create actual products or prices in your Stripe dashboard without specific instructions and credentials.
