Show HN: Spec Driven Development Plugin for Claude Code (github.com)

Claude Code has unveiled a new plugin, ShipSpec, aimed at enhancing spec-driven development for large features. While Claude’s native plan mode works well for smaller tasks, larger feature development often results in vague and high-level outlines, leading to implementation errors and misaligned architecture decisions. ShipSpec addresses these challenges by introducing structured Product Requirements Documents (PRDs) and Software Design Documents (SDDs), ensuring that the development process stays anchored to the original requirements and design intent throughout the implementation phase. The plugin introduces several key features: it facilitates clear requirements gathering through interactive Q&A sessions, creates detailed technical designs connected to the existing codebase, and generates manageable implementation tasks with acceptance criteria. Additionally, integrated verification processes ensure each task aligns with the expected outcomes. By systematically breaking down complex features into well-defined tasks, ShipSpec promotes a coherent and organized approach to development, reducing the risk of "hallucinations" during coding and ensuring that architectural decisions are consistently applied. This robust framework stands to significantly streamline the development process for AI/ML applications, enhancing both productivity and quality.
