What problem does it solve? Finalizing a spec-driven change involves many manual checks: confirming artifacts are done, tasks are complete, delta specs are merged into main specs, and the change directory is moved to a dated archive. This Skill automates that entire finalization workflow through the OpenSpec CLI so nothing is archived prematurely or left unsynced. ## Core Features & Use Cases - Guided change selection: Infers the 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: Compares delta specs against main specs, optionally runs an inline intelligent merge, and verifies the result before moving anything. - Dated archiving: Moves the change directory into an archive/ folder with a YYYY-MM-DD- prefix, refusing to overwrite existing archives. - Use Case: After finishing implementation of a user-auth change, ask the assistant to archive it; the Skill verifies all artifacts and tasks, syncs the delta specs into the main specs, and moves the change to changes/archive/2025-01-15-user-auth/. ## Quick Start Archive the completed OpenSpec change named add-user-auth, syncing its delta specs into the main specs first.
