Documentation Auditor (L2 Coordinator)

Coordinates 4 specialized audit workers to perform comprehensive documentation quality analysis.

Purpose & Scope

• Coordinates 4 audit workers running in parallel:
  • ln-611 (documentation structure) — 1 invocation
  • ln-612 (semantic content) — N invocations (per target document)
  • ln-613 (code comments) — 1 invocation
  • ln-614 (fact verification) — 1 invocation
• Detect project type + tech stack ONCE
• Pass shared context to all workers (token-efficient)
• Aggregate worker results into single consolidated report
• Write report to docs/project/docs_audit.md (file-based, no task creation)
• Manual invocation by user or called by ln-100-documents-pipeline

Workflow

1. Discovery: Detect project type, tech stack, scan .md files
2. Context Build: Build contextStore with output_dir, project_root, tech_stack
3. Prepare Output: Create output directory
4. Delegate: Invoke 4 workers in parallel
5. Aggregate: Collect worker results, calculate overall score
6. Context Validation: Post-filter findings
7. Write Report: Save to docs/project/docs_audit.md
8. Results Log: Append trend row
9. Cleanup: Delete worker files

Phase 1: Discovery

Load project metadata:

• CLAUDE.md — root of documentation hierarchy
• docs/README.md — documentation index
• Package manifests: package.json, requirements.txt, go.mod, Cargo.toml
• Existing docs in docs/project/

Extract:

• Programming language(s)
• Major frameworks/libraries
• List of .md files in project (for ln-611 hierarchy check)
• Target documents for semantic audit (for ln-612)

Target documents for ln-612:

FOR doc IN [CLAUDE.md, docs/README.md, docs/documentation_standards.md,
            docs/principles.md, docs/project/*.md]:
  IF doc exists AND doc NOT IN [docs/tasks/*, docs/reference/*, docs/presentation/*]:
    semantic_targets.append(doc)

Phase 2: Build contextStore

{
  "tech_stack": {"language": "...", "frameworks": [...]},
  "project_root": "...",
  "output_dir": "docs/project/.audit/ln-610/{YYYY-MM-DD}"
}

Where {YYYY-MM-DD} is current date (e.g., 2026-03-01).

Phase 3: Prepare Output

mkdir -p {output_dir}

Worker files are cleaned up after consolidation (see Phase 9).

Phase 4: Delegate to Workers

MANDATORY READ: Load shared/references/task_delegation_pattern.md.

All workers in PARALLEL via Agent tool:

ln-614 receives only contextStore and discovers .md files internally. Workers follow the shared file-based audit contract and return compact summaries with report path, score, and severity counts.

Invocation:

// Global workers (ln-611, ln-613, ln-614) — 1 invocation each:
FOR EACH worker IN [ln-611, ln-613, ln-614]:
  Agent(description: "Docs audit via " + worker,
       prompt: "Execute audit worker.

Step 1: Invoke worker:
  Skill(skill: \"" + worker + "\")

CONTEXT:
" + JSON.stringify(contextStore),
       subagent_type: "general-purpose")

// Per-document worker (ln-612) — N invocations:
FOR EACH doc IN semantic_targets:
  doc_context = { ...contextStore, doc_path: doc }
  Agent(description: "Semantic audit " + doc + " via ln-612",
       prompt: "Execute audit worker.

Step 1: Invoke worker:
  Skill(skill: \"ln-612-semantic-content-auditor\")

CONTEXT:
" + JSON.stringify(doc_context),
       subagent_type: "general-purpose")

Phase 5: Aggregate Results

MANDATORY READ: Load shared/references/audit_coordinator_aggregation.md.

Use the shared aggregation pattern for summary parsing, worker report reads, severity rollups, and final report assembly.

Category weights:

Calculate overall score as the weighted average of the 4 categories above.

Phase 6: Context Validation (Post-Filter)

MANDATORY READ: Load shared/references/context_validation.md

Apply Rule 1 + documentation-specific inline filters:

FOR EACH finding WHERE severity IN (HIGH, MEDIUM):
  # Rule 1: ADR/Planned Override
  IF finding matches ADR → advisory "[Planned: ADR-XXX]"

  # Doc-specific: Compression context (from ln-611)
  IF Structure finding Cat 3 (Compression):
    - Skip if path in references/ or templates/ (reference docs = naturally large)
    - Skip if filename contains architecture/design/api_spec
    - Skip if tables+lists > 50% of content (already structured)

  # Fact-checker: Example/template path exclusion (from ln-614)
  IF Fact finding (PATH_NOT_FOUND):
    - Path in examples/ or templates/ directory reference → advisory
    - Path has placeholder pattern (YOUR_*, <project>, {name}) → remove

  # Fact-checker: Planned feature claims (from ln-614)
  IF Fact finding (ENTITY_NOT_FOUND, ENDPOINT_NOT_FOUND):
    - Entity mentioned in ADR/roadmap as planned → advisory "[Planned: ADR-XXX]"

  # Fact-checker: Cross-doc contradiction authority (from ln-614)
  IF Fact finding (CROSS_DOC_*_CONFLICT):
    - docs/project/ is authority over docs/reference/ → report reference doc

  # Comment-specific: Per-category density targets (from ln-613)
  IF Comment finding Cat 2 (Density):
    - test/ or tests/ → target density 2-10%
    - infra/ or config/ or ci/ → target density 5-15%
    - business/domain/services → target density 15-25%
    Recalculate with per-category target.

  # Comment-specific: Complexity context for WHY-not-WHAT (from ln-613)
  IF Comment finding Cat 1 (WHY not WHAT):
    - If file McCabe complexity > 15 → WHAT comments acceptable
    - If file in domain/ or business/ → explanatory comments OK

Downgraded findings → "Advisory Findings" section in report.

Phase 7: Write Report

Write consolidated report to docs/project/docs_audit.md:

## Documentation Audit Report - {DATE}

### Overall Score: X.X/10

| Category | Score | Worker | Issues |
|----------|-------|--------|--------|
| Documentation Structure | X/10 | ln-611 | N issues |
| Semantic Content | X/10 | ln-612 | N issues (across M docs) |
| Code Comments | X/10 | ln-613 | N issues |
| Fact Accuracy | X/10 | ln-614 | N issues |

### Critical Findings

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

### Advisory Findings

(Context-validated findings downgraded from MEDIUM/HIGH)

### Recommended Actions

| Priority | Action | Location | Category |
|----------|--------|----------|----------|
| High | ... | ... | ... |

Scoring Algorithm

MANDATORY READ: Load shared/references/audit_scoring.md.

Critical Notes

• Pure coordinator: Does NOT perform any audit checks directly. ALL auditing delegated to workers.
• Fix content, not rules: NEVER modify standards/rules files to make violations pass
• Fact verification via ln-614: Dedicated worker extracts and verifies all claims across ALL docs
• Compress always: Size limits are upper bounds, not targets
• No code in docs: Documents describe algorithms in tables or ASCII diagrams
• Code is truth: When docs contradict code, always update docs
• Delete, don't archive: Legacy content removed, not archived

Phase 8: Append Results Log

MANDATORY READ: Load shared/references/results_log_pattern.md

Append one row to docs/project/.audit/results_log.md with: Skill=ln-610, Metric=overall_score, Scale=0-10, Score from Phase 7 report. Calculate Delta vs previous ln-610 row. Create file with header if missing. Rolling window: max 50 entries.

Phase 9: Cleanup Worker Files

rm -rf {output_dir}

Delete the dated output directory (docs/project/.audit/ln-610/{YYYY-MM-DD}/). The consolidated report and results log already preserve all audit data.

Definition of Done

• Project metadata discovered (tech stack, doc list)
• contextStore built with output_dir = docs/project/.audit/ln-610/{YYYY-MM-DD}
• Output directory created for worker reports
• All 4 workers invoked and completed
• Worker reports aggregated: 4 category scores + overall
• Context Validation applied to all findings
• Consolidated report written to docs/project/docs_audit.md
• Results log row appended to docs/project/.audit/results_log.md
• Worker output directory cleaned up after consolidation

Phase 10: Meta-Analysis

MANDATORY READ: Load shared/references/meta_analysis_protocol.md

Skill type: review-coordinator (workers only). Run after all phases complete. Output to chat using the review-coordinator — workers only format.

Reference Files

• Context validation rules: shared/references/context_validation.md
