What problem does it solve? Finalizing a completed change in an OpenSpec-driven workflow involves many manual steps: verifying artifacts and tasks, syncing delta specs, moving directories, updating changelogs and feature docs, and closing GitHub issues. This Skill orchestrates that entire archival process with validation gates so nothing is archived prematurely or left inconsistent. ## Core Features & Use Cases - Completion validation: Checks artifact status via openspec status --json, reconciles tasks.md against GitHub tracking issues, and blocks archiving when required work is incomplete unless the user explicitly overrides. - Spec and documentation sync: Compares delta specs against main specs, converts test-plan cases into reusable TS-NNN test scenario files, updates feature docs, and appends a Keep a Changelog entry. - Use Case: After finishing the register-export change, run the archive command to move it into openspec/changes/archive/YYYY-MM-DD-register-export/, sync its delta specs, update CHANGELOG.md, and close the linked GitHub issue in one guided flow. ## Quick Start Ask the assistant to archive the completed change named register-export using the opsx-archive workflow.
