What problem does it solve? When a change plan evolves, its proposal, design, specs, and tasks drift out of sync. This Skill revises an existing OpenSpec change's planning artifacts so they stay consistent with one another after new decisions or edits, 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: Drafts edits in conversation, confirms each one with the user, then applies revisions one artifact at a time using paths reported by the openspec CLI. - Store and Schema Awareness: Supports registered OpenSpec stores via --store <id> and works with custom schemas by reading artifact ids from openspec status instead of hardcoding names. - Use Case: After deciding the design should use a different approach, ask the assistant to update the change; it revises the design artifact and reconciles the proposal and specs to match. ## Quick Start Ask the assistant to update the OpenSpec change named "add-auth" so its design and specs reflect the new decision.
