What problem does it solve? Finalizing a completed change in an OpenSpec workflow involves multiple manual checks—artifact completion, task status, and delta spec synchronization—before safely moving the change into the archive. This Skill automates that entire finalization sequence with the openspec CLI. ## Core Features & Use Cases - Guided Change Selection: Resolves the target change from user input, conversation context, or an interactive prompt listing active changes. - Pre-Archive Verification: Checks artifact completion via openspec status --json, counts incomplete tasks in tasks.md, and warns before proceeding. - Delta Spec Sync Assessment: Compares delta specs against main specs, optionally runs an inline sync workflow, and verifies the result before archiving. - Use Case: After finishing implementation of a feature change, ask the assistant to archive it; the Skill validates everything, syncs specs if needed, and moves the change into a date-prefixed archive directory. ## Quick Start Archive the completed change 'add-user-auth' and sync its delta specs to the main specs before archiving.
