LLM Wiki: Health Check

Audit the wiki for structural issues, content gaps, and maintenance needs.

Step 1: Inventory

1. Glob all .md files in wiki/ recursively.
2. For each file, read frontmatter and extract:
   • title, type, tags, sources, created, updated
3. Scan each file's content for all [[wikilinks]].
4. Build a page inventory and a link graph.

Step 2: Structural Checks

Broken Wikilinks

• Find all [[Target]] references across the wiki
• Check if a page with that title exists (case-insensitive filename match)
• Report any broken links (target page doesn't exist)

Orphan Pages

• Pages with zero inbound links from other wiki pages
• Exclude index.md and log.md from this check
• Orphans are pages nobody references — they may be forgotten or poorly integrated

Missing Pages

• Wikilinks that point to non-existent pages — these are implicit "wanted pages"
• Rank by how many pages link to them (higher = more important to create)

Frontmatter Issues

• Pages missing required frontmatter fields (title, type, created)
• Pages with type that doesn't match their directory (e.g., type: entity in concepts/)
• Pages with empty or placeholder content

Naming Convention Violations

• Files not using lowercase kebab-case
• Files with spaces or special characters
• Extremely long filenames

Step 3: Content Checks

Stale Content

• Pages where updated date is more than 30 days old AND newer sources exist that mention the same entities/concepts
• Source summaries whose original source file has been modified since the summary was written

Contradictions

• Use parallel subagents to spot-check key claims across pages:
  • Find pages about the same entity/concept
  • Compare claims, numbers, dates between them
  • Flag any inconsistencies with specific quotes from each page

Thin Pages

• Pages with very little content (< 100 words excluding frontmatter)
• Pages that are just stubs with no real information
• Source summaries that lack key takeaways

Coverage Gaps

• Entities mentioned in 3+ sources but lacking their own page
• Concepts that appear frequently in tags but have no dedicated page
• Topics where only one source covers them (single-source risk)

Step 4: Source Drift Check (Manifest)

Read wiki/.manifest.json and verify source integrity:

1. For each entry in the manifest, compute the current MD5 of the source file:

   md5 -q <file>
   

2. Compare against the stored hash. Report:
   • Modified sources: MD5 differs — the source has changed since last ingest. Wiki pages may be stale. Suggest running /llmwiki:ingest to re-process.
   • Deleted sources: File no longer exists on disk. Wiki pages referencing it may be orphaned.
   • Untracked sources: Files in raw/, docs/, notes/ that aren't in the manifest at all — never ingested.
3. Summarize: N modified, N deleted, N untracked out of N total tracked sources.

Step 5: Index & Log Checks

Index Accuracy

• Compare wiki/index.md entries against actual files
• Pages in the wiki but missing from the index
• Index entries pointing to deleted/renamed pages

Log Completeness

• Check that recent file changes have corresponding log entries
• Identify files with no ingest log entry (possible manual additions)

Step 6: qmd Health

Check qmd status:

qmd status

• Is the wiki collection registered?
• How many documents are indexed vs. exist on disk?
• Are embeddings up to date?

If out of sync, suggest running qmd update and/or qmd embed.

Step 7: Generate Report

Present findings organized by severity:

Critical (fix now)

• Broken wikilinks
• Contradictions between pages
• Index out of sync
• Modified sources with stale wiki pages (run /llmwiki:ingest)

Warning (fix soon)

• Orphan pages
• Stale content
• Thin pages
• Frontmatter issues

Info (nice to have)

• Missing pages (wanted but not created)
• Coverage gaps
• Synthesis opportunities
• Naming convention issues

Statistics

• Total pages: N (entities: N, concepts: N, sources: N, comparisons: N, synthesis: N)
• Total wikilinks: N (broken: N)
• Orphan pages: N
• Average page age: N days
• Most connected pages (top 5 by link count)
• Least connected pages (excluding new pages)

Suggested Actions

Prioritized list of maintenance tasks:

1. Fix broken wikilinks (list specific fixes)
2. Resolve contradictions (list specific pages)
3. Create wanted pages (list top 5 by demand)
4. Update stale pages (list specific pages)
5. Write synthesis pages for well-covered topics

Step 8: Log

Append to wiki/log.md:

## [YYYY-MM-DD] health | Wiki health check
- Total pages: N
- Broken links: N
- Orphans: N
- Contradictions: N
- Stale pages: N
- Health score: N/100

Calculate health score:

• Start at 100
• -5 per broken wikilink
• -3 per orphan page
• -10 per contradiction
• -2 per stale page
• -1 per thin page
• -2 per index mismatch
• -5 per modified source not re-ingested
• -3 per deleted source with orphaned wiki pages
• Floor at 0
