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 verification and archiving process so completed changes are closed out consistently without losing spec updates. ## 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 items. - 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, failing cleanly if the target already exists. - Use Case: After finishing implementation of a feature 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 into the archive with a summary report. ## Quick Start Archive the completed change "add-user-auth" and sync its delta specs to the main specs before moving it.
