To create a feature design document, you generate a complete skeleton covering the overview, architecture description, critical constraints, domain model, and implementation plan, linking the concept to formal requirements.

A feature design doc must include an overview, architecture description, critical constraints, domain model, module structure, design decisions, and an implementation plan to guide development effectively.

You update an existing design doc by applying new requirements or scope changes to the architecture description and domain model, ensuring traceability between the original concept, requirements, and implementation plan.

Yes, you can scaffold architecture and data flow decisions by generating a formal feature design document that defines the module structure, domain model, and critical technical constraints before implementation begins.

Yes, formal requirements and an existing feature concept are needed beforehand, as the design document enforces traceability and links architecture decisions directly back to the established requirements.
