What problem does it solve? Keeping a project's governing principles consistent across spec-kit artifacts is error-prone when done manually. This Skill fills the constitution template at .specify/memory/constitution.md with concrete values and propagates amendments to dependent templates. ## Core Features & Use Cases - Constitution Authoring: Collects or derives values for every placeholder token (project name, principles, governance dates) and writes a complete constitution. - Semantic Versioning of Governance: Automatically bumps CONSTITUTION_VERSION using MAJOR/MINOR/PATCH rules based on the nature of the changes. - Consistency Propagation: Validates and updates plan-template.md, spec-template.md, tasks-template.md, and related command files, then prepends a Sync Impact Report. - Use Case: After deciding to add a new testing-discipline principle, run this Skill to amend the constitution to a new minor version and flag every template that must reflect the new rule. ## Quick Start Ask the agent to update the project constitution with your new principle and keep all spec-kit templates in sync.
