name: ln-600-docs-auditor description: Audit project documentation quality across 6 categories (Hierarchy, SSOT, Compactness, Requirements, Actuality, Legacy). Use when documentation needs quality review, after major doc updates, or as part of ln-100-documents-pipeline. Outputs Compliance Score X/10 per category + Findings + Recommended Actions.

Documentation Auditor

Audit project documentation quality. Universal for any tech stack.

Purpose

• Proactively compress - find all opportunities to reduce size while preserving value
• Eliminate meaningless, redundant, and verbose content
• Convert prose to structured formats (tables, lists)
• Verify documentation hierarchy with CLAUDE.md as root
• Detect duplication and enforce Single Source of Truth
• Ensure docs match current code state

Invocation

• Direct: User invokes for documentation quality review
• Pipeline: Called by ln-100-documents-pipeline (Phase 5, if auditDocs=true)

Workflow

1. Scan: Find all .md files in project (CLAUDE.md, README.md, docs/**)
2. Build Tree: Construct hierarchy from CLAUDE.md outward links
3. Audit: Run 6 category checks (see Audit Categories below)
4. Score: Calculate X/10 per category
5. Report: Output findings and recommended actions

Audit Categories

#	Category	What to Check
1	Hierarchy & Links	CLAUDE.md is root; all docs reachable via links; no orphaned files; no broken links
2	Single Source of Truth	No content duplication; duplicates replaced with links to source; clear ownership
3	Proactive Compression	Eliminate verbose/redundant content; prose→tables; remove meaningless info; compress even under-limit files; see size_limits.md
4	Requirements Compliance	Correct sections; within size limits; no code blocks (tables/ASCII-схемы/text only); stack-appropriate doc links
5	Actuality (CRITICAL)	Verify facts against code: paths exist, functions match, APIs work, configs valid; outdated docs are worse than none
6	Legacy Cleanup	No history sections; no "was changed" notes; no deprecated info; current state only
7	Stack Adaptation	Links/refs match project stack; no Python examples in .NET project; official docs for correct platform

Output Format

## Documentation Audit Report - [DATE]

### Compliance Score

| Category | Score | Issues |
|----------|-------|--------|
| Hierarchy & Links | X/10 | N issues found |
| Single Source of Truth | X/10 | N duplications |
| Proactive Compression | X/10 | N compression opportunities |
| Requirements Compliance | X/10 | N violations |
| Actuality | X/10 | N mismatches with code |
| Legacy Cleanup | X/10 | N legacy items |
| Stack Adaptation | X/10 | N stack mismatches |
| **Overall** | **X/10** | |

### Critical Findings

- [ ] **[Category]** `path/file.md:line` - Issue description. **Action:** Fix suggestion.

### Recommended Actions

| Priority | Action | Location | Category |
|----------|--------|----------|----------|
| High | Remove duplicate section | docs/X.md | SSOT |
| Medium | Add link to CLAUDE.md | docs/Y.md | Hierarchy |

Scoring Rules

Score	Meaning
10/10	No issues
8-9/10	Minor issues (formatting, small redundancies)
6-7/10	Moderate issues (some duplication, missing links)
4-5/10	Significant issues (orphaned docs, outdated content)
1-3/10	Critical issues (major mismatches, broken hierarchy)

Reference Files

• Size limits and targets: references/size_limits.md
• Detailed checklist: references/audit_checklist.md

Critical Notes

• Fix content, not rules: NEVER modify standards/rules files (*_standards.md, *_rules.md, *_limits.md) to make violations pass. Always fix the violating files instead.
• Verify facts against code: Actively check every path, function name, API, config mentioned in docs. Run commands. Outdated docs mislead - they're worse than no docs.
• Compress always: Size limits are upper bounds, not targets. A 100-line file instead of 300 is a win. Always look for compression opportunities.
• Meaningless content: Remove filler words, obvious statements, over-explanations. If it doesn't add value, delete it.
• No code in docs: Documents describe algorithms in tables or ASCII-схемы. Code belongs in codebase.
  • Forbidden: Code blocks, implementation snippets
  • Allowed: Tables, ASCII diagrams, Mermaid, method signatures (1 line)
  • Instead of code: "See Official docs" or "See src/file.cs:42"
• Format Priority: Tables/ASCII > Lists (enumerations only) > Text (last resort)
• Stack adaptation: Verify all documentation references match project stack. .NET project must not have Python examples. Check official doc links point to correct platform (Microsoft docs for C#, MDN for JS, etc.)
• Code is truth: When docs contradict code, always update docs. Never "fix" code to match documentation.
• Delete, don't archive: Legacy content should be removed, not moved to "archive"
• No history: Documents describe current state only; git tracks history
