Wiki Lint — Knowledge Base Health Check

Systematic audit of wiki health across 8 dimensions.

Resolve target paths from system/config.md when available. If no config exists, use the default STOW layout and write the report to system/lint-report.md.

Usage Template

Prompt

Use wiki-lint on my vault. Check frontmatter, broken links, orphans, stale pages, contradictions, drift, stats, and index health.

Use Case

• Maintaining a growing Obsidian or markdown wiki before it becomes hard to trust or navigate.

Expected Result

• The agent produces a lint report with ranked issues and concrete repair actions.

Output Example

• A lint report grouped by severity with file paths, issue counts, and repair checklist.

Verification Case

• The report includes file paths, issue counts, severity, and at least one recommended fix per high-priority issue.

Verified Effect

• Wiki health becomes visible through ranked issues instead of vague feelings that the vault is disorganized.

Success Metrics

• Report includes issue counts, severity, file paths, and recommended fixes.
• Broken links, orphans, missing frontmatter, stale pages, and source-protection risks are checked or marked not applicable.
• No source files are modified during linting.
• P0/P1 checks can prove main graph health after an ingest: no empty files, missing wiki frontmatter, broken source refs, zero-inlink wiki pages, or wiki pages with fewer than two outbound links.
• Concept-page quality checks separate real understanding from raw summaries: thesis, mechanism, source boundary, uncertainty, and connections.

When to Use

• User says "lint the wiki", "health check", "run lint"
• Periodically (weekly recommended)
• Before/after major batch operations
• When wiki feels disorganized

Check 1: Frontmatter Integrity

Scan every wiki page for:

• [ ] Missing type: field
• [ ] Missing status: field
• [ ] Missing created: field
• [ ] Pages without frontmatter entirely
• [ ] Legacy status values (e.g., seedling → seed)
• [ ] Missing knowledge_stage: or evidence_level: on V5 pages
• [ ] Source files missing source_id, hash, trust_level, or status are reported as provenance debt; do not fabricate values

Check 2: Broken Links

• [ ] Find [[wikilinks]] pointing to non-existent pages
• [ ] Find (Source: [[...]]) references to missing source files
• [ ] Distinguish true missing sources from weak concept/entity links and example-text false positives

Check 3: Orphan Pages

• [ ] Pages with zero incoming [[wikilinks]]
• [ ] Pages with zero outgoing [[wikilinks]] (violates ≥2 rule)

Check 4: Stale Content

• [ ] Pages not updated in >90 days with status: growing or higher
• [ ] Pages with status: stale that should be archived or refreshed

Check 5: Contradictions

• [ ] Conflicting claims across different sources on the same topic
• [ ] Missing > [!warning] Contradiction markers

Check 6: Single-Source Claims

• [ ] Pages with evidence_level: single-source that have accumulated multiple sources

Check 7: Page Structure Standards ⭐

• [ ] Concept pages missing leading quote block (core thesis)
• [ ] Concept pages missing --- separator before timeline
• [ ] Concept pages missing ## 演化时间线 section
• [ ] Concept pages missing ## 关联 or ## Connections section
• [ ] Pages with no ASCII diagram or comparison table for framework-type content
• [ ] New pages without ≥2 outgoing [[wikilinks]]
• [ ] Concept pages that summarize a source without a mechanism, boundary, uncertainty, or reusable insight

Check 7A: Karpathy Understanding Integrity

Flag pages that violate LLM Wiki intent:

Check 8: Statistical Drift

• [ ] Compare actual file counts vs overview.md claims
• [ ] Verify central index includes all pages
• [ ] Verify all new pages appear in the correct index section

Check 9: Clipping Queue and Source Lifecycle

• [ ] Processed clippings are in Clippings/archive/
• [ ] Clippings/README.md queue counts and processed-source table are current when present
• [ ] Duplicate clippings point to canonical source notes instead of creating parallel facts

Check 10: Permissions

• [ ] No unintended modifications to sources/ files
• [ ] Review-queue items addressed
