workflow-erd

Generate ERDs from functional specs, PRDs, or domain descriptions. A solid ERD design leads to better UI design and more reliable API implementation. This is a Layer 2 skill (optional harness).

Why ERD matters in the workflow

/workflow-idea → PRD + Functional Spec
       ↓
/workflow-erd → ERD (data relationships become concrete)
       ↓
  Better understanding of domains → better UI design, better API design

The functional spec tells you "what to build". The ERD tells you "what data exists and how it connects". This concreteness cascades into everything downstream.
