What is the Epic architecture pattern used here?

It is a three-layer backend structure where integrations live in the Infrastructure layer, separated from Backend Actions and the Frontend to ensure clear separation of concerns.

Does it handle API rate limiting and retries?

Yes, the skill generates a standardized implementation pattern that includes configurable retry logic for transient failures and handles 429 rate limit responses.

Why does the skill include the 'server-only' import?

The 'server-only' import prevents infrastructure code, which often contains sensitive logic or secrets, from accidentally being imported into the frontend client bundle.

Can I use this for non-API business logic?

While primarily for external APIs, this skill is perfect for any complex, reusable business logic that needs to be isolated in the Infrastructure layer.

API Development

Architects and implements external service integrations following the Epic three-layer infrastructure pattern.

This skill streamlines the creation of backend integrations by enforcing a standardized three-layer architecture. It scaffolds robust services for third-party APIs—such as Stripe, OpenAI, or Twilio—ensuring code remains strictly server-side, follows consistent error handling patterns, and incorporates built-in retry logic. It is an essential tool for developers using the Epic architecture who need to maintain clear boundaries between their frontend, backend actions, and external infrastructure layers while ensuring type safety and reliability.
