What problem does it solve? SDD artifacts like spec.md, plan.md, and tasks.md often drift away from the canonical template structure over time, making them inconsistent and harder for AI agents to consume. This Skill normalizes existing artifacts to the canonical format without losing any original content. ## Core Features & Use Cases - Canonical Reorganization: Maps existing sections of spec.md, plan.md, tasks.md, CLAUDE.md, and llms.txt to their canonical template structures. - Content Preservation: Guarantees no original content is discarded; unmatched content moves to a Notes section and placeholders like {{...}} stay intact. - Confirmation-First Workflow: Always presents a diff summary of renamed, moved, and added sections and requires user approval before writing changes. - Use Case: You inherited a project where spec.md uses custom headings and plan.md mixes architecture decisions with task lists. Run this Skill to normalize both files to the canonical SDD templates while keeping every sentence of the original. ## Quick Start Ask the assistant to refactor the artifact at specs/features/001-login/spec.md into the canonical SDD format and show the diff before saving.
