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 - 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 agent-driven sync, and verifies the result before archiving. - Dated archival: 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 agent 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 and sync its delta specs into the main specs first.
