Health-check the wiki for contradictions, orphan pages, stale claims, and missing cross-references. Use when the user says "audit", "health check", "lint", "find problems", or wants to improve wiki quality.

Second Brain — Lint Health check the wiki and report issues with actionable fixes. Audit Steps Run all checks below, then present a consolidated report. 1. Broken wikilinks Scan all wiki pages for [[wikilink]] references. For each link, verify the target page exists. Report any broken links. Cross reference against actual files in wiki/ . 2. Orphan pages Find pages with no inbound links — no other page references them via [[wikilink]] . For each .md file in wiki/sources/ , wiki/entities/ , wiki/concepts/ , wiki/synthesis/ : Extract the page name (filename without extension) Search all other wiki pages for [[Page Name]] If no other page links to it, it's an orphan 3. Contradictions Read pages that share entities or concepts and look for conflicting claims. Flag when: Two source summaries make opposing claims about the same topic An entity page contains information that conflicts with a source summary Dates, figures, or factual claims differ between pages 4. Stale claims Cross reference source dates with wiki content. Flag when: A concept page cites only old sources and newer sources exist on the same topic Entity information hasn't been updated despite newer sources mentioning that entity 5. Missing pages Scan for [[wikilinks]] that point to pages that don't exist yet. These are topics the wiki mentions but hasn't given their own page. Assess whether they warrant a page. 6. Missing cross references Find pages that discuss the same topics but don't link to each other. Look for: Entity pages that mention concepts without linking them Concept pages that mention entities without linking them Source summaries that cover the same topic but don't reference each other 7. Index consistency Verify wiki/index.md is complete and accurate: Every page in wiki/sources/ , wiki/entities/ , wiki/concepts/ , wiki/synthesis/ has an index entry No index entries point to deleted pages Entries are under the correct category header 8. Data gaps Based on the wiki's current coverage, suggest: Topics mentioned frequently but lacking depth Questions the wiki can't answer well Areas where a web search could fill in missing information Report Format Present findings grouped by severity: Errors (must fix) Broken wikilinks Contradictions between pages Index entries pointing to missing pages Warnings (should fix) Orphan pages with no inbound links Stale claims from outdated sources Missing pages for frequently referenced topics Info (nice to fix) Potential cross references to add Data gaps that could be filled Index entries that could be more descriptive For each finding, include: What: description of the issue Where: the specific file(s) and line(s) Fix: what to do about it After the Report Ask the user: "Found N errors, N warnings, and N info items. Want me to fix any of these?" If the user agrees, fix issues and report what changed. Log the lint pass Append to wiki/log.md : [YYYY MM DD] lint Health check Found N errors, N warnings, N info items. Fixed: [list of fixes applied].
