FAQPage Schema

How do I generate UML sequence diagrams from use case specifications?▼

To generate UML sequence diagrams from use cases, provide a project usecase-output.json and a domain-model json file. The skill translates these inputs into detailed PlantUML sequence diagrams to visualize runtime interactions.

Can I create multilingual PlantUML sequence diagrams from a domain model?▼

Yes, you can create multilingual PlantUML sequence diagrams. The skill inherits language settings directly from the domain model to produce localized messages for each sequence diagram.

Does this tool output XMI models and JSON payloads for sequence diagrams?▼

Yes, the tool outputs optional XMI models and structured JSON payloads for sequence diagrams. These outputs facilitate downstream automation and integration with other software engineering tools.

How do I visualize extension flows in UML sequence diagrams?▼

To visualize extension flows in UML sequence diagrams, the skill automatically generates per-use-case diagrams that include extension flow diagrams. This covers complex runtime scenarios across the domain model.

What is needed to convert domain models and use cases into sequence diagrams?▼

To convert domain models and use cases into sequence diagrams, you need a usecase-output.json file and a domain-model json. Running the skill with these inputs produces the diagrams and metadata.

What is the best way to document runtime interactions from use cases?▼

The best way to document runtime interactions from use cases is translating specifications into UML sequence diagrams. This approach visualizes runtime behavior and guides implementation using PlantUML and JSON.
