Implements Magento 2 interceptors to modify core and third-party module behavior without inheritance or core code modifications.

This skill provides Claude with the specialized knowledge required to develop Magento 2 plugins (interceptors), a core architectural pattern for extending platform functionality. It guides the creation of before, after, and around methods, ensures correct di.xml configuration, and adheres to Adobe Commerce best practices. By automating the boilerplate and logic for intercepting public methods, it enables developers to customize checkout, product logic, and API responses while maintaining upgradeability and preventing conflicts between modules.
