概要
The sdd-modify skill is a specialized component of the Spec-Driven Development (SDD) workflow designed to automate structural changes to project specifications. It enables developers to seamlessly integrate feedback from plan and fidelity reviews, perform bulk metadata updates, and manage task hierarchies while maintaining a strictly validated source of truth. By leveraging dry-run previews, automatic backups, and post-modification integrity checks, the skill ensures that complex specification updates never compromise project structure or consistency.
