Paths: File paths (shared/, references/, ../ln-*) are relative to skills repo root. If not found at CWD, locate this SKILL.md directory and go up one level for repo root. If shared/ is missing, fetch files via WebFetch from https://raw.githubusercontent.com/levnikolaevich/claude-code-skills/master/skills/{path}.

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

Severity Mapping

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
