What problem does it solve? Versioning canonical documentation in the mj-agent repository requires coordinated file moves, frontmatter state changes, archive banners, and corpus-wide wikilink audits. Doing this manually risks broken links, inconsistent states, and lost history. This Skill orchestrates the full Major.Minor archive workflow per ADR-011 and ADR-014. ## Core Features & Use Cases - Standard version archive: Moves the old version to docs/archive/<subdir>/ via git mv, flips state to deprecated, adds an archive banner, and promotes the new version to active. - Skeleton-first delayed promote: Handles the ADR-014 variant where a new draft coexists with the old active version across multiple PRs before a single promote PR. - Living vs frozen reference audit: Greps the corpus for wikilinks to the old version, classifies each as living (upgrade to new version) or frozen (pin to archive path), and syncs INDEX.md. - Use Case: When promoting mj-agent docs from v2.0 to v2.1, run this Skill to archive the old trio, activate the new trio, update all references, and validate with check_frontmatter.py and check_wikilinks.py. ## Quick Start Ask the agent to archive the old version and promote the new one, for example: run the doc migrate workflow to move STANDARD Meta Framework v2.0 to archive and promote v2.1 to active.
