What problem does it solve? When a spec-driven change plan evolves, its proposal, design, specs, and task artifacts drift out of sync. This Skill revises an existing OpenSpec change's planning artifacts and reconciles them against each other, without 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 and detects contradictions, gaps, and duplication in any direction across the build order. - Confirmed Edits Only: Proposes each revision, waits for user confirmation, and edits only files in existingOutputPaths — never creating new artifacts or writing to glob patterns. - Use Case: After deciding the design now uses a different storage approach, ask the assistant to update the change; it revises the design doc, reconciles the proposal and specs, and points you to /opsx-apply for the code delta. ## Quick Start Ask the assistant to update the OpenSpec change named "add-auth" so its design and specs reflect the new decision to use token-based sessions.
