What problem does it solve? Finalizing a completed change in an OpenSpec workflow involves several manual checks—artifact completion, task status, and delta spec synchronization—before the change directory can be safely moved to the archive. This Skill automates that verification and archival process so completed changes are closed out consistently without losing spec updates. ## Core Features & Use Cases - 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, optionally runs an inline sync merge, and verifies the result before archiving. - Store-Aware Archiving: Supports registered OpenSpec stores via --store <id> and moves the change directory into a date-prefixed archive folder. - Use Case: After finishing implementation of a user-auth change, ask the agent to archive it; the Skill confirms all artifacts are done, syncs spec deltas into the main specs, and moves the change to changes/archive/2025-01-15-user-auth. ## Quick Start Ask the agent to archive the completed change named add-user-auth and confirm any warnings about incomplete tasks.
