What problem does it solve? Finalizing a completed change in an OpenSpec workflow involves several manual checks—artifact completion, task status, delta spec synchronization, and moving files into a dated archive—which are easy to skip or perform inconsistently. ## Core Features & Use Cases - Guided Change Selection: Resolves the target change from user input, conversation context, or an interactive prompt listing active changes. - Completion Verification: Checks artifact status via openspec status --json and counts incomplete tasks in tasks.md before archiving, warning but not blocking on gaps. - Delta Spec Sync Assessment: Compares delta specs against main specs, optionally runs an inline sync workflow, and verifies the result before moving anything. - Dated Archiving: Moves the change directory into an archive folder with a YYYY-MM-DD- prefix, preventing duplicate targets. - Use Case: After finishing implementation of a user-auth change, ask the assistant to archive it; it confirms all artifacts are done, syncs the delta specs into the main specs, and moves the change to the archive with a dated name. ## Quick Start Archive the completed change named add-user-auth and sync its delta specs into the main specs before moving it to the archive.
