What problem does it solve? Finalizing a completed change in an OpenSpec workflow involves several manual checks: confirming artifacts are done, verifying tasks are complete, syncing delta specs into main specs, and moving the change directory into an archive. This Skill automates that entire finalization sequence through the openspec CLI. ## Core Features & Use Cases - Guided change selection: Infers the change from context, auto-selects when only one active change exists, 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 but not blocking on gaps. - Delta spec sync: Compares delta specs against main specs, optionally runs an inline sync workflow, and verifies the merge before archiving. - Safe archiving: Moves the change directory into a date-prefixed archive folder, failing safely if the target already exists. - Use Case: After finishing implementation of a user-auth change, ask the assistant to archive it; the Skill verifies all artifacts, syncs spec deltas, and moves the change to changes/archive/2025-01-15-user-auth. ## Quick Start Archive the completed OpenSpec change named add-user-auth and sync its delta specs into the main specs first.
