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 so nothing is archived prematurely or left out of sync. ## Core Features & Use Cases - Guided Change Selection: Resolves the target change from context, auto-selects when only one is active, or prompts with a list of active changes when ambiguous. - Completion Verification: Checks artifact status via openspec status --json and counts incomplete tasks in tasks.md, warning before archiving with open items. - Delta Spec Sync Assessment: Compares delta specs against main specs, offers to sync via the openspec-sync-specs workflow, and verifies the merge before moving anything. - Use Case: After finishing implementation of a feature change, ask the assistant to archive it; the Skill validates all artifacts, optionally syncs specs into the main spec tree, then moves the change into a date-prefixed archive directory. ## Quick Start Ask the assistant to archive the completed OpenSpec change, optionally naming the change to finalize.
