What problem does it solve? Knowledge bases accumulate structural rot over time: broken wikilinks, hardcoded user paths, tag drift, stale verification stamps, and broken supersede chains. This Skill audits an entire vault for these hygiene issues and optionally applies the two mechanically safe fixes, so you can keep a vault trustworthy without manually inspecting every note. ## Core Features & Use Cases - Vault-wide hygiene audit: Detects 16 rule violations across six categories including unresolved wikilinks, basename collisions, hardcoded /Users/ paths, tag aliases, taxonomy drift, stale verification, and supersede-chain defects, each with a severity level. - Conservative auto-remediation: With --apply, performs only the two mechanically safe fixes: tag canonicalization (delegated to kb-edit) and path-only wikilink rewrites that preserve aliases, anchors, and link style. Everything else stays report-only with a named follow-up command. - Structured JSON output: Returns findings partitioned by severity, a summary, and per-fix results, with categorical error codes like invalid-config, no-kb-resolvable, and readonly-kb. - Use Case: Run a read-only report on your coding knowledge base with a 30-day staleness threshold, review the findings, then apply the safe fixes and manually handle the report-only items using the named kb-edit follow-up commands. ## Quick Start Ask the agent to audit the coding knowledge base for hygiene issues and apply the safe fixes.
