Documentation Structure Auditor (L3 Worker)

Type: L3 Worker

Specialized worker auditing structural quality of project documentation.

Purpose & Scope

• Audit documentation for structural quality across 8 categories
• Scan all .md files in project, build hierarchy from AGENTS.md when present
• Return structured findings to coordinator with severity, location, recommendations
• Calculate compliance score (X/10) for Documentation Structure

Inputs

MANDATORY READ: Load references/audit_worker_core_contract.md, references/docs_quality_contract.md, and references/markdown_read_protocol.md. Optional rule catalog: load references/docs_quality_rules.json only when exact rule IDs, path matrices, or allowlisted placeholder exceptions are needed. Tool policy: follow host AGENTS.md MCP preferences; load references/mcp_tool_preferences.md and references/mcp_integration_patterns.md only when host policy is absent or MCP behavior is unclear.

Receives contextStore with: tech_stack, project_root, output_dir.

hex-line is optional for this doc-only worker. Use it as an accelerator for large markdown outlines and targeted reads when available; otherwise continue with built-in Read/Grep/Glob/Bash.

Workflow

1) Parse Context: Extract tech stack, project root, output_dir from contextStore 2) Load Registry if Present: Use docs/project/.context/doc_registry.json as the first routing source when available 3) Scan Docs: Find all .md files in project (AGENTS.md, CLAUDE.md, README.md, docs/) 4) Read Section-First: For larger docs, outline first, then read header markers + Quick Navigation + Agent Entry + Maintenance 5) Build Tree: Construct hierarchy from AGENTS.md outward links when present, otherwise from CLAUDE.md 6) Audit Categories 1-7: Run structural checks (see Audit Categories below) 7) Collect Findings: Record each violation with severity, location (file:line), effort estimate (S/M/L), recommendation 8) Calculate Score: Count violations by severity, calculate compliance score (X/10) 9) Write Report: Build full markdown report per references/templates/audit_worker_report_template.md, write to {output_dir}/611-structure.md in single Write call 10) Return Summary:** Return minimal summary to coordinator (see Output Format)

Audit Categories

| # | Category | What to Check | |---|----------|---------------| | 1 | Hierarchy & Links | AGENTS.md is canonical root when present; 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](references/size_limits.md) | | 4 | Requirements Compliance | Correct header markers, correct top sections, within size limits, no illegal code blocks, stack-appropriate doc links | | 5 | Freshness Indicators | Detect staleness signals: dates >6 months in content, unsupported 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 unsupported info; current state only | | 7 | Stack Adaptation | Links/refs match project stack; no Python examples in .NET project; official docs for correct platform | | 8 | Import Pattern Compliance | When AGENTS.md exists at repo root, CLAUDE.md must contain exactly one @AGENTS.md line and a bounded harness-specific delta (≤50 lines total). Any content in CLAUDE.md that duplicates AGENTS.md is drift. See references/agent_instructions_writing_guide.md for rationale |

Severity Mapping

| Issue Type | Severity | |------------|----------| | Staleness indicators (old dates, unsupported refs, TODO markers) | MEDIUM | | Broken links, orphaned docs | HIGH | | Content duplication | MEDIUM | | Missing compression opportunity | LOW | | Legacy/history content | MEDIUM | | Wrong stack references | HIGH | | Import pattern drift (duplicated AGENTS.md content in CLAUDE.md, oversized stub, missing @AGENTS.md line) | HIGH |

Scoring Algorithm

MANDATORY READ: Load references/audit_scoring.md.

Output Format

MANDATORY READ: Load references/templates/audit_worker_report_template.md.

Write JSON summary per references/audit_summary_contract.md. In managed mode the caller passes both runId and summaryArtifactPath; in standalone mode the worker generates its own run-scoped artifact path per shared contract.

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, import_pattern_compliance.

Return summary per references/audit_summary_contract.md.

Standalone mode still writes the same JSON summary to a worker-owned run-scoped artifact path per shared contract.

Critical Rules

Apply the already-loaded 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, unsupported 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
• Shared contract precedence: Placeholder policy, template-metadata policy, and no-code exceptions come from docs_quality_contract.md / docs_quality_rules.json

Definition of Done

Apply the already-loaded references/audit_worker_core_contract.md.
