To generate a User Story document from screen mockups and data models, provide the UI mockups and data model ERD to analyze screen-to-data interactions. The process outputs a unified document containing a Mermaid Sequence Diagram, API specifications with validation, and a Rule mapping table.

Screen-to-data flow analysis works by tracing user interactions from the UI through to the data layer to determine read and write operations. This mechanism identifies the necessary data sequences and generates an API specification complete with validation rules and actions.

The Mermaid Sequence Diagram for a Happy Path includes the interaction flow between User, Frontend, and Backend. It specifically excludes the Database object from the diagram, focusing purely on the application layer communication sequence.

Yes, you can use this feature analyzer for planned development features. It applies to features in current or planned development by feeding screen mockups and data models, meaning an existing backend is not required to map the sequence and API specifications.

The best way to map validation rules and actions from UI interactions is to analyze the screen-to-data interactions comprehensively. This produces a compiled Rule mapping table that pairs API endpoints with their specific validation and action requirements.

Yes, you need to provide a data model ERD to generate the API specification and Rule mapping table. The screen mockups supply the interaction flow while the ERD supplies the data structure required to output accurate API validation and rules.
