Spec-Driven Development Skill

A comprehensive SDLC workflow that creates specifications BEFORE implementation, ensuring alignment, traceability, and regression prevention.

Core Philosophy

1. Specifications are Executable - Specs generate working implementations
2. Mandatory Approval Gates - No proceeding without explicit user approval
3. Regression Prevention - Document unchanged behavior to protect existing functionality
4. Progressive Refinement - Clarify → Specify → Validate → Implement
