twelve-factor-backing-services

What problem does it solve?

This skill helps teams analyze the Twelve-Factor App Factor IV (Backing Services) to validate that external services are treated as attachable resources configured via environment settings, ensuring portability and replaceability across deployments.

Core Features & Use Cases

• Validate that external services (databases, caches, message queues, SMTP, and APIs) are consumed through configuration rather than hard-coded references.
• Provide an audit trail and guidance for refactors to increase decoupling and maintainability.
• Use cases include migrating from code-bound dependencies to environment-driven bindings in audits, designs, and documentation.

Quick Start

Identify all external backing services used by your app and verify they can be swapped via configuration without code changes.
