This integrates GitHub's Spec-Kit CLI to walk you through constitution-based feature development in seven phases, from establishing project principles to implementation. It automates the workflow of creating numbered spec directories, running the right CLI commands, and detecting which phase you're in based on what files exist. You'd use this when you want structured, principle-driven development instead of jumping straight to code. The constitution phase is interesting because it forces you to write down your project's values and decision criteria before writing any specs. Requires Python 3.11+, uv, and the spec-kit CLI installed. Works in Chinese and English.
