What problem does it solve? Finalizing a completed change in an OpenSpec workflow involves several error-prone manual steps: checking artifact completion, verifying tasks, syncing delta specs into main specs, and moving the change directory into a dated archive. This Skill automates that entire finalization sequence with built-in verification and confirmation prompts. ## Core Features & Use Cases - Completion Verification: Checks artifact status via openspec status --json and counts incomplete tasks in tasks.md, warning before archiving unfinished work. - Delta Spec Sync Assessment: Compares delta specs against main specs, summarizes pending adds, modifications, removals, and renames, and optionally runs an inline sync before archiving. - Dated Archive Move: Moves the change directory into an archive/ folder with a YYYY-MM-DD- prefixed name, failing safely if the target already exists. - Use Case: After implementing a feature tracked as an OpenSpec change, ask the assistant to archive it; the Skill verifies all artifacts and tasks, syncs specs if needed, and moves the change into the archive with a summary report. ## Quick Start Ask the assistant to archive the completed OpenSpec change, optionally naming the change to archive.
