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 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 proceeding. - Delta spec sync: Compares delta specs against main specs, optionally runs an inline intelligent merge, and verifies the result before archiving. - 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 feature change, ask the assistant to archive it; the Skill validates everything, syncs specs if needed, and produces a summary of what was archived. ## Quick Start Ask the assistant to archive the completed change named add-user-auth using the openspec archive workflow.
