What problem does it solve? Keeping main specifications in sync 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 into the main specs, without archiving the change. ## Core Features & Use Cases - Intelligent Merging: Reads each delta spec and merges requirements into main specs while preserving existing scenarios and content the delta does not mention. - Store-Aware Operation: Supports registered OpenSpec stores via --store <id> so specs in standalone repositories can be synced from anywhere. - Safe Capability Retirement: Deletes a capability's spec.md only when strict conditions hold (empty requirements, valid Purpose, retire_capabilities: true marker), and validates results with openspec validate --specs. - Use Case: After finishing a change that adds scenarios to the user-auth capability, run the sync to update openspec/specs/user-auth/spec.md in place while keeping the change active for continued work. ## Quick Start Ask the assistant to sync the delta specs from a named change into the main specs, for example: sync the specs from my add-billing-invoices change without archiving it.
