What problem does it solve? Keeping main specifications aligned with change proposals is tedious and error-prone when done by hand. This Skill applies delta specs (ADDED, MODIFIED, REMOVED, RENAMED requirements) from an OpenSpec change directly to the main spec files, with intelligent merging instead of wholesale replacement. ## Core Features & Use Cases - Intelligent Delta Merging: Reads delta specs and applies partial updates to main specs, preserving existing scenarios and content not mentioned in the delta. - Change Selection Workflow: Lists available changes via the openspec CLI and prompts the user to select one, avoiding guesswork. - New Capability Creation: Creates new main spec files with Purpose and Requirements sections when a capability does not exist yet. - Use Case: After drafting a change proposal with delta specs for a new API feature, run this Skill to merge those requirements into the main specs while keeping the change active until implementation is archived. ## Quick Start Ask the assistant to sync the delta specs from a specific OpenSpec change into the main specs without archiving the change.
