What problem does it solve? Finalizing a completed change in an OpenSpec workflow involves several manual checks—artifact completion, task status, and delta spec synchronization—before the change directory can be safely moved to the archive. This Skill automates that entire finalization sequence so nothing is archived prematurely or left out of sync. ## 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 unfinished work. - Delta spec sync assessment: Compares delta specs against main specs, optionally runs an inline sync workflow, and verifies the result before archiving. - Safe archiving: Moves the change directory into a date-prefixed archive folder, refusing to overwrite existing archives. - Use Case: After finishing implementation of a user-auth change, ask the assistant to archive it; the Skill confirms all artifacts are done, syncs spec deltas to the main specs, and moves the change to archive/2024-01-15-user-auth. ## Quick Start Archive the completed OpenSpec change named add-user-auth and sync its delta specs to the main specs first.
