What problem does it solve? Finalizing a completed change in an OpenSpec workflow involves several error-prone manual checks: confirming artifacts are done, verifying tasks are complete, syncing delta specs into main specs, and moving the change directory into a dated archive. This Skill automates that entire finalization sequence with the openspec CLI. ## Core Features & Use Cases - Change Selection & Validation: Resolves the target change from user input or conversation context, checks artifact completion via openspec status --json, and counts incomplete tasks before archiving. - Delta Spec Sync Assessment: Compares delta specs against main specs, prompts to sync, runs the sync workflow inline, and verifies every capability matches before proceeding. - Safe Archive Execution: Creates the archive directory, generates a YYYY-MM-DD- prefixed target name without double-dating, detects name collisions, and moves the change directory. - Use Case: After finishing implementation of a feature change, ask the assistant to archive it; the Skill warns about 2 incomplete tasks, syncs the delta specs into the main specs, and moves the change to changes/archive/2025-01-15-my-change/. ## Quick Start Archive the completed change named add-user-auth and sync its delta specs into the main specs before moving it.
