What problem does it solve? When a change plan evolves, its existing planning artifacts (proposals, designs, specs, tasks) drift out of sync with each other. This Skill revises an OpenSpec change's existing artifacts and keeps them mutually consistent without ever touching implementation code. ## Core Features & Use Cases - Change Selection: Infers the target change from context or lists the most recently modified changes via openspec list --json when ambiguous. - Coherence Review: Reads all existing artifacts reported by openspec status --change <name> --json and reconciles contradictions, gaps, and duplication in any direction. - Confirmed Edits Only: Proposes each revision, writes only after user confirmation, and never creates new artifacts or edits code. - Use Case: After deciding the design now uses a different storage approach, ask the Skill to update the change; it revises the design artifact and reconciles the proposal and tasks to match. ## Quick Start Ask the assistant to update the current OpenSpec change so its design reflects the new decision and the other artifacts stay consistent.
