What problem does it solve? When an OpenSpec change's plan evolves, its existing artifacts (proposal, design, tasks, specs) drift out of sync. This Skill revises those artifacts and keeps them mutually consistent without touching implementation code. ## Core Features & Use Cases - Coherence Review: Reads all existing artifacts of a change and detects contradictions, gaps, and duplication across them. - Guided Revision: Proposes edits one artifact at a time and writes only after user confirmation, using artifact ids and paths reported by the openspec CLI. - Store-Aware Workflow: Supports registered OpenSpec stores via --store <id> and works with custom schemas without hardcoded artifact names. - Use Case: After deciding the design now uses a different approach, ask the Skill to fold that decision into the change; it updates the design artifact and reconciles the proposal and tasks accordingly. ## Quick Start Ask the assistant to update the OpenSpec change named my-change so its artifacts reflect the new design decision and stay consistent.
