What problem does it solve? When a change plan evolves, its OpenSpec planning artifacts (proposals, designs, specs, tasks) drift out of sync. This Skill revises existing artifacts of an OpenSpec change and reconciles them against one another so the plan stays internally consistent, without ever touching implementation code. ## Core Features & Use Cases - Coherence Review: Reads all existing artifacts of a change and detects contradictions, gaps, and duplication across them in any direction. - Confirmed Revisions: Proposes each edit, explains why, and writes only after user confirmation, one artifact at a time. - Schema-Agnostic Operation: Uses artifact ids and paths reported by openspec status --json, so custom schemas work without hardcoded assumptions. - Use Case: After deciding the design now uses a message queue instead of direct API calls, ask the Skill to update the change; it revises the design artifact and reconciles the proposal, specs, and tasks to match. ## Quick Start Ask the assistant to update the OpenSpec change named "add-caching" so its planning artifacts reflect the new design decision and stay consistent.
