What problem does it solve? When a personal knowledge wiki drifts too far from its sources, incremental fixes stop working. This Skill provides a safe, structured way to snapshot the current wiki state, wipe it clean for a full rebuild, or roll back to a previous archive without losing data. ## Core Features & Use Cases - Archive Only: Snapshot the entire wiki (categories, index, log, manifest) into a timestamped _archives/ directory with metadata, leaving the live wiki untouched. - Archive + Rebuild: Archive the current state, clear all category directories, reset index.md and log.md, and prepare the vault for selective re-ingest via wiki-status, claude-history-ingest, codex-history-ingest, and wiki-ingest. - Restore from Archive: List available archives with page/source counts, archive the current state first as insurance, then restore a chosen snapshot and verify it. - QMD Index Sync: Refresh the QMD search index after destructive operations so search results match the live wiki, with graceful fallback when the QMD CLI is unavailable. - Use Case: Your Obsidian wiki has accumulated stale pages after months of ingestion. Run an archive-and-rebuild to snapshot 87 pages, clear the vault, then re-ingest only the sources that still matter. ## Quick Start Ask the assistant to archive the current wiki and rebuild it from scratch, confirming the operation before anything is deleted.
