What problem does it solve? Personal knowledge wikis degrade over time: pages become orphaned, links break, information goes stale, and contradictions accumulate silently. This Skill performs a systematic health check across all wiki topic pages and produces a prioritized report so you can fix issues before knowledge quality erodes. ## Core Features & Use Cases - 13-Point Health Audit: Checks orphan pages, dead links, stale pages (90+ days), contradictions, missing cross-references, missing topics, oversized pages, data gaps, ingest activity, infobox integrity, index description quality, facet bloat, and hub block drift. - Report-First, Approval-Gated Fixes: Generates a structured Wiki Health Report and only edits index.md, Related sections, or log.md after explicit user approval. - Use Case: Run a monthly wiki review by asking for a health check; the Skill scans every topic page in 30-knowledge/00-wiki, flags a page whose Last enriched date is 120 days old, finds two dead wikilinks, and proposes index.md additions for three orphan pages. ## Quick Start Ask the assistant to run a wiki health check on the 00-wiki directory and show the report before making any fixes.
