SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

PRD provides high-level goals but lacks a concrete, testable SPEC; this Skill transforms PRD into precise, implementable specifications that guide architecture, API design, data modeling, and verification.

Core Features & Use Cases

  • PRD-to-SPEC mapping with full traceability from requirements to endpoints.
  • AC mapping and validation to ensure every PRD acceptance criterion is covered.
  • Phase-driven workflow guidance including architecture diagrams (Mermaid) and Given-When-Then criteria.

Quick Start

Provide the PRD file path or feature name to generate the SPEC.

Frequently Asked Questions about sdd-spec

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I convert a PRD into a testable SPEC for software development?▼

To convert a PRD into a testable SPEC, you translate high-level goals into rigorous specifications covering architecture, API design, data modeling, and verification criteria. This ensures every requirement is concrete and implementable.

What is AC mapping and how does it validate feature requirements?▼

AC mapping links each PRD acceptance criterion to specific SPEC endpoints and validation rules. This ensures full traceability and verifies that every feature requirement is covered by testable Given-When-Then conditions.

How to generate architecture diagrams and phase workflows from a PRD?▼

Generating architecture diagrams and phase workflows from a PRD involves structuring the SPEC into implementation phases. This includes creating Mermaid diagrams for architecture and defining step-by-step phase-driven guidance for development.

Does SPEC generation work for full-stack features spanning both server and client components?▼

Yes, SPEC generation applies to full-stack feature creation spanning both server and client components. It handles end-to-end specifications including PRD-driven data modeling and API design without relying on technology-stack specifics.

What is the best way to ensure traceability from PRD requirements to API endpoints?▼

The best way to ensure traceability from PRD requirements to API endpoints is using PRD-to-SPEC mapping. This transforms high-level goals into precise specifications with full traceability linking every requirement to its corresponding endpoints.
