4-Phase Development Workflow

A structured approach from requirements to production-ready code

1

Specification

PM Role

Generate Gherkin specifications from user requirements. Define clear acceptance criteria and business scenarios.

$ /sdd-spec <requirement>
2

Architecture

Architect Role

Design high-level architecture from Gherkin specs. Define data models and service interfaces.

$ /sdd-arch <feature_file_path>
3

Implementation

Engineer Role

Implement code based on architecture design. Satisfy all Gherkin specifications automatically.

$ /sdd-impl <feature_file_path>
4

Verification

QA Role

Verify implementation against specifications. Generate comprehensive verification reports.

$ /sdd-verify <feature_file_path>

Automatic Mode

Execute all 4 phases with a single command

$ /sdd-auto <requirement>
