Documentation Structure Auditor (L3 Worker)

Specialized worker auditing structural quality of project documentation.

Purpose & Scope

• Worker in ln-610 coordinator pipeline - invoked by ln-610-docs-auditor
• Audit documentation for structural quality across 7 categories
• Scan all .md files in project, build hierarchy from CLAUDE.md
• Return structured findings to coordinator with severity, location, recommendations
• Calculate compliance score (X/10) for Documentation Structure

Inputs (from Coordinator)

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

Receives contextStore with: tech_stack, project_root, output_dir.

Workflow

1. Parse Context: Extract tech stack, project root, output_dir from contextStore
2. Scan Docs: Find all .md files in project (CLAUDE.md, README.md, docs/**)
3. Build Tree: Construct hierarchy from CLAUDE.md outward links
4. Audit Categories 1-7: Run structural checks (see Audit Categories below)
5. Collect Findings: Record each violation with severity, location (file:line), effort estimate (S/M/L), recommendation
6. Calculate Score: Count violations by severity, calculate compliance score (X/10)
7. Write Report: Build full markdown report per shared/templates/audit_worker_report_template.md, write to {output_dir}/611-structure.md in single Write call
8. Return Summary: Return minimal summary to coordinator (see Output Format)

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 to 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 diagrams/text only); stack-appropriate doc links
5	Freshness Indicators	Detect staleness signals: dates >6 months in content, deprecated API/tool references, TODO/FIXME markers, placeholder text left in place; deep fact-checking handled by dedicated worker
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

Severity Mapping

Issue Type	Severity
Staleness indicators (old dates, deprecated refs, TODO markers)	MEDIUM
Broken links, orphaned docs	HIGH
Content duplication	MEDIUM
Missing compression opportunity	LOW
Legacy/history content	MEDIUM
Wrong stack references	HIGH

Scoring Algorithm

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

Output Format

MANDATORY READ: Load shared/references/audit_worker_core_contract.md and shared/templates/audit_worker_report_template.md.

Write report to {output_dir}/611-structure.md with category: "Documentation Structure" and checks: hierarchy_links, ssot, compression, requirements_compliance, freshness_indicators, legacy_cleanup, stack_adaptation.

Return summary to coordinator:

Report written: docs/project/.audit/ln-610/{YYYY-MM-DD}/611-structure.md
Score: X.X/10 | Issues: N (C:N H:N M:N L:N)

Critical Rules

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

• Do not auto-fix: Report violations only; coordinator aggregates for user
• Tech stack aware: Use contextStore tech_stack to apply stack-specific checks (e.g., .NET vs Node.js doc standards)
• No deep fact-checking: Detect staleness signals only (dates, deprecated refs, TODO markers)
• Compress always: Size limits are upper bounds, not targets. A 100-line file instead of 300 is a win
• No code in docs: Documents describe algorithms in tables or ASCII diagrams. Code belongs in codebase
• Code is truth: When docs contradict code, report docs as needing update (not code)
• Delete, don't archive: Legacy content should be removed, not moved to "archive"
• Location precision: Always include file:line for programmatic navigation

Definition of Done

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

• contextStore parsed successfully (including output_dir)
• All 7 structural categories audited
• Findings collected with severity, location, effort, recommendation
• Score calculated using penalty algorithm
• Report written to {output_dir}/611-structure.md (atomic single Write call)
• Summary returned to coordinator

Reference Files

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