Product Spec Kit

概要

Streamlines the product management lifecycle by providing specialized workflows for creating, refining, and maintaining high-quality product specifications. By enforcing a strict constitution based on design-driven development, it ensures all documentation—from high-level PRDs to granular user stories—is functional, unambiguous, and grounded in visual user flows. This skill bridges the gap between design and engineering by facilitating structured breakdowns of epics into testable tasks while prioritizing validation over assumption, ensuring that development teams receive clear and actionable requirements.
