What does the Workflow Engine Generator do?

It automates the creation of step handlers, retry policies, and processing logic for stateful workflows in Java applications using Domain-Driven Design.

What testing is included with the generated workflows?

The generator produces unit tests for step definitions and retry policies, as well as integration tests for store leases and state transitions.

Is the generated code idempotent?

Yes, the skill follows strict implementation rules to ensure all generated workflow steps are replay-safe and idempotent, preventing side effects during retries.

Does it support complex branching logic?

By default, it generates linear execution chains based on a responsibility chain pattern, but it provides the foundation to be extended for more complex logic.

API Development

Automates the creation of robust workflow engines, step handlers, and retry policies for Java-based DDD applications.

The App Common Workflow Generator is designed to streamline the implementation of stateful, linear workflows within the app-common module of a Java DDD scaffold. It automates the generation of idempotent step handlers, configurable retry policies, and core services for starting and signaling workflows. By enforcing architectural patterns such as guarded state transitions and responsibility chains, it ensures that developers can quickly build fault-tolerant business processes while maintaining consistency across the codebase.
