Architecture Documentation Auditor

A systematic audit system that evaluates Architecture Documentation against a comprehensive 188-item viewpoint-based checklist, detecting gaps, classifying severity, identifying technical debt signals, scanning for architecture anti-patterns, and generating actionable remediation roadmaps. Implements the GAP-AUDIT pattern (PATTERN-08) to produce CONTRACT-07 compliant GAP-INVENTORY output with Architecture Health Score extensions.

1. Purpose

This skill provides 12 core capabilities:

#	Capability	Phase	Description
1	Framework Detect	1	Identify architecture framework (TOGAF, C4, arc42, IEEE 42010)
2	Document Parse	1	Extract architecture structure, diagrams, and decision records
3	Viewpoint Map	2	Apply 14-viewpoint coverage framework to document sections
4	Item-by-Item Verify	3	Check each of 188 checklist items against content
5	Gap Detect	3	Identify missing, incomplete, or inconsistent elements
6	Classify Gap Type	4	Categorize gaps using 6-type taxonomy
7	Score Severity	4	Apply RUBRIC-07 (impact, likelihood, detectability)
8	Anti-Pattern Scan	5	Detect 25 architecture anti-patterns
9	Debt Signal Detect	5	Identify 25+ technical debt indicators
10	Quality Attribute Validate	4	Verify ISO 25010 quality attribute coverage
11	Remediate Suggest	5	Generate fix recommendations with effort estimates
12	Synthesize Report	6	Produce GAP-INVENTORY + Health Score + Debt Roadmap

2. When to Use

Ideal for:

•Architecture review gates before implementation
•ADR validation before development starts
•C4 diagram completeness verification
•Technical debt assessment and tracking
•Pre-implementation readiness check
•Governance and compliance audits
•Design document handoff to development teams
•Architecture decision board preparation
•System modernization planning
•Security architecture review

Avoid when:

•Document is code, not architecture (use code review)
•Operational runbook review (use operations auditor)
•Early ideation phase (architecture not yet defined)
•Quick clarifying questions (formal audit adds overhead)
•Infrastructure-as-Code review (use IaC auditor)
•API specification only (use API spec auditor)

4. Six-Phase Workflow

Phase 1: Document Intake & Framework Detection

Purpose: Load document and establish audit context.

Steps:

•Receive architecture document (inline or file reference)
•
Detect architecture framework:
- •C4: Look for Context/Container/Component/Code levels
- •arc42: Look for 12-section template structure
- •TOGAF: Look for ADM phase artifacts
- •IEEE 42010: Look for formal viewpoint definitions
•Load architecture-checklist.md reference
•
Calibrate checklist based on document_type:
- •Filter items by viewpoint applicability
- •Adjust severity levels for document type
- •Set critical items that must be present
•
Parse document to identify structure:
- •Extract section headers and hierarchy
- •Identify diagram references and types
- •Note ADRs (Architecture Decision Records)
- •Detect technology stack references
•Load viewpoint-catalog.md for structural validation
•Initialize gap tracking structure with empty findings

Techniques Used:

•document_structure_extraction - Parse document hierarchy
•framework_detection - Identify architecture methodology
•checklist_calibration - Adjust criteria for context

Quality Gate: Framework identified; checklist calibrated for document type; structure parsed with sections identified

Output: Calibrated checklist (N items) + Document structure map + Detected framework

Phase 2: Viewpoint Mapping & Scope Definition

Purpose: Map document sections to architecture viewpoints and identify structural gaps.

Steps:

•
Load viewpoint framework from viewpoint-catalog.md:

Core Viewpoints (Always Assess):
- •V1: Context & Scope (system boundary, external actors)
- •V2: Container Architecture (major components, technology choices)
- •V3: Component Design (internal structure, interfaces)
- •V4: Deployment Topology (infrastructure, scaling)
- •V5: Data Architecture (data stores, flows, ownership)
- •V6: Integration & APIs (contracts, protocols, versioning)
- •V7: Security Architecture (auth, encryption, compliance)
- •V8: Operational Concerns (monitoring, SLOs, runbooks)
- •V9: Cross-Cutting Concerns (logging, caching, config)
- •V10: Decision Record (ADRs, rationale, consequences)
Conditional Viewpoints (If Applicable):
- •V11: Multi-tenancy (SaaS/multi-tenant systems)
- •V12: Event Architecture (event-driven systems)
- •V13: Migration Path (legacy modernization)
- •V14: Compliance Matrix (regulated industries)
•
Map each document section to viewpoints:
- •Assign based on content, not just header
- •Flag orphan sections (don't fit any viewpoint)
- •Flag missing viewpoints (no sections mapped)
•
Identify structural gaps:
- •Core viewpoint with no coverage = CRITICAL structural gap
- •Core viewpoint with partial coverage = HIGH structural gap
- •Conditional viewpoint missing when applicable = MEDIUM gap
•
Check for applicable conditional viewpoints:
- •Multi-tenancy: Evidence of tenant-based requirements
- •Event architecture: Event-driven patterns mentioned
- •Migration: Legacy system references
- •Compliance: Regulatory requirements mentioned
•
Calculate initial coverage score per viewpoint

Techniques Used:

•completeness_verification (CAT-PR-GA) - Verify all viewpoints addressed
•viewpoint_mapping - Map sections to architectural concerns

Quality Gate: All applicable viewpoints assessed; structural gaps flagged

Output: Viewpoint coverage map with scores and structural gap list

Phase 3: Systematic Coverage Verification

Purpose: Verify each checklist item against document content.

Steps:

For each checklist item (V1-01 through V10-20):

code

1. LOCATE RELEVANT SECTION
   └─ Based on viewpoint mapping from Phase 2

2. ASSESS PRESENCE
   ├─ PRESENT: Item clearly addressed
   ├─ PARTIAL: Item mentioned but incomplete
   └─ ABSENT: No evidence of item

3. EVALUATE QUALITY (if present)
   ├─ CLEAR: Unambiguous and actionable
   ├─ AMBIGUOUS: Multiple interpretations possible
   ├─ INCONSISTENT: Contradicts other content
   ├─ INCOMPLETE: Missing key details
   └─ OUTDATED: Stale or deprecated references

4. RECORD EVIDENCE
   ├─ Location: Section/diagram reference
   ├─ Quote: Supporting text from document
   └─ Assessment: Pass/fail with rationale

5. FLAG FOR GAP CLASSIFICATION (if needed)
   └─ Any non-PRESENT or non-CLEAR items

Verification Rules by Viewpoint:

Viewpoint	Items	Critical Items	Verification Approach
V1: Context	V1-01 to V1-15	V1-01, V1-02, V1-03	Check boundary definition, external actors
V2: Container	V2-01 to V2-25	V2-01, V2-02, V2-05	Verify technology choices documented
V3: Component	V3-01 to V3-18	V3-01, V3-02	Check internal structure clarity
V4: Deployment	V4-01 to V4-22	V4-01, V4-05, V4-10	Verify infrastructure defined
V5: Data	V5-01 to V5-18	V5-01, V5-02, V5-05	Check data stores and flows
V6: Integration	V6-01 to V6-15	V6-01, V6-02, V6-05	Verify API contracts exist
V7: Security	V7-01 to V7-25	V7-01, V7-02, V7-05, V7-10	Check auth, encryption, audit
V8: Operations	V8-01 to V8-18	V8-01, V8-05, V8-10	Verify monitoring, SLOs defined
V9: Cross-Cutting	V9-01 to V9-12	V9-01, V9-05	Check logging, config patterns
V10: Decisions	V10-01 to V10-20	V10-01, V10-02, V10-05	Verify ADR structure and coverage

Techniques Used:

•completeness_verification (CAT-PR-GA) - Check presence of each item
•negative_space_analysis (CAT-PR-GA) - Identify what's NOT documented
•consistency_check (CAT-PR-ECR) - Cross-reference between viewpoints

Quality Gate: 100% of applicable checklist items evaluated

Output: Verification matrix with item-level results and evidence

Phase 4: Quality Attribute Validation

Purpose: Validate coverage of ISO 25010 quality attributes.

Steps:

4.1 Quality Attribute Mapping

Map document content to quality attributes from quality-attributes.md:

Quality Attribute	Primary Viewpoints	Validation Criteria
Performance	V4, V5	Latency targets, throughput requirements, resource limits
Scalability	V4, V2	Scaling strategy, elasticity approach, capacity planning
Security	V7, V6	Auth mechanisms, encryption, audit logging, compliance
Reliability	V8, V4	Availability targets, fault tolerance, DR strategy
Maintainability	V3, V10	Modularity, testability, decision rationale
Interoperability	V6, V1	API standards, protocol choices, versioning
Portability	V4, V2	Platform dependencies, abstraction layers
Usability	V6, V10	API ergonomics, developer experience

4.2 Coverage Assessment

For each quality attribute:

•Identify explicit coverage in primary viewpoints
•Check for implicit coverage in secondary viewpoints
•Assess coverage level: EXPLICIT / IMPLICIT / MISSING
•Note measurement approaches if present

4.3 Gap Identification

Flag quality attribute gaps:

•MISSING in primary viewpoint = HIGH gap
•MISSING in all viewpoints = CRITICAL gap for regulated contexts

Techniques Used:

•quality_attribute_validation - Map concerns to ISO 25010
•coverage_assessment - Evaluate attribute coverage

Quality Gate: All quality attributes assessed with coverage level

Output: Quality attribute coverage matrix

Phase 5: Technical Debt & Anti-Pattern Detection

Purpose: Identify technical debt signals and architecture anti-patterns.

Steps:

5.1 Gap Classification

For each gap identified in Phases 3-4, apply gap taxonomy (from gap-taxonomy.md):

code

IS ELEMENT PRESENT?
├─ NO → MISSING
└─ YES
    ├─ IS IT COMPLETE?
    │   ├─ NO → INCOMPLETE
    │   └─ YES
    │       ├─ DOES IT CONTRADICT OTHER CONTENT?
    │       │   ├─ YES → INCONSISTENT
    │       │   └─ NO
    │       │       ├─ IS IT CLEAR AND UNAMBIGUOUS?
    │       │       │   ├─ NO → AMBIGUOUS
    │       │       │   └─ YES
    │       │       │       ├─ IS IT TECHNICALLY CORRECT?
    │       │       │       │   ├─ NO → INCORRECT
    │       │       │       │   └─ YES
    │       │       │       │       └─ IS IT CURRENT?
    │       │       │       │           ├─ NO → OUTDATED
    │       │       │       │           └─ YES → No gap

5.2 Severity Scoring

Apply SEVERITY-SCORING (RUBRIC-07) with three dimensions:

Dimension	Weight	Scale
Impact	0.5	1=Low, 2=Medium, 3=High, 4=Critical
Likelihood	0.3	1=Rare, 2=Possible, 3=Likely, 4=Certain
Detectability	0.2	1=Obvious, 2=Moderate, 3=Difficult, 4=Hidden

Calculation:

code

severity_score = (impact × 0.5) + (likelihood × 0.3) + (detectability × 0.2)

CRITICAL: score >= 3.5
HIGH: 2.5 <= score < 3.5
MEDIUM: 1.5 <= score < 2.5
LOW: score < 1.5

5.3 Architecture Anti-Pattern Scan

If include_anti_patterns is true, scan for 25 patterns from anti-patterns-catalog.md:

Structural Anti-Patterns:

•full_consistency_matrix (CAT-PR-ECR) - Cross-reference for inconsistencies
•anti_pattern_detection - Match known failure patterns
•debt_signal_detection - Identify technical debt indicators

Quality Gate: All gaps classified with type and severity; anti-patterns and debt signals detected

Output: Classified gap list + Anti-pattern findings + Debt indicators

Phase 6: Synthesis & Governance Reporting

Purpose: Produce final GAP-INVENTORY artifact with Architecture Health Score.

Steps:

6.1 GAP-INVENTORY Compilation

Compile all findings into CONTRACT-07 compliant structure:

•Populate source_reference with document identifier
•Set source_type to "architecture"
•Build audit_criteria with viewpoint-based checklist
•Compile gaps array with all classified gaps
•Add anti_patterns array if detected
•Add technical_debt section with indicators
•Calculate summary statistics

6.2 Architecture Health Score

Calculate overall architecture health:

xml

<architecture_health>
  <overall_score>[0-100]</overall_score>
  <by_viewpoint>
    <!-- Score per viewpoint -->
  </by_viewpoint>
  <by_quality_attribute>
    <!-- Coverage per ISO 25010 attribute -->
  </by_quality_attribute>
  <technical_debt_summary>
    <!-- Debt indicator counts by category -->
  </technical_debt_summary>
  <c4_maturity>
    <!-- Completeness of C4 levels if applicable -->
  </c4_maturity>
</architecture_health>

Health Score Calculation:

code

viewpoint_score = (items_passed / items_total) × 100 per viewpoint
overall_score = weighted_average(viewpoint_scores) - severity_penalties

Severity Penalties:
- CRITICAL gap: -10 points
- HIGH gap: -5 points
- Anti-pattern: -3 points
- Debt indicator: -2 points

Health Status Thresholds:

Status	Score Range	Interpretation
HEALTHY	80-100	Ready for implementation
ADEQUATE	60-79	Minor gaps, proceed with awareness
AT_RISK	40-59	Significant gaps, address before proceeding
CRITICAL	0-39	Major gaps, not ready for implementation

6.3 Summary Statistics

Generate:

•total_gaps: Count of all gaps
•by_severity: {critical: N, high: N, medium: N, low: N}
•by_category: {missing: N, incomplete: N, inconsistent: N, ...}
•by_viewpoint: Gap count per viewpoint
•overall_assessment: Based on health score
•blocking_issues: List of gap IDs that must be fixed
•coverage_score: Percentage of checklist items passed

Assessment Thresholds:

Assessment	Criteria
critical_issues	Any CRITICAL gap OR overall_score < 40
significant_gaps	No CRITICAL but score 40-59 OR >3 HIGH gaps
minor_issues	Score 60-79, only MEDIUM/LOW gaps

•Priority 2: Short-term (before implementation)
•Priority 3: Medium-term (during implementation)
•Priority 4: Long-term (continuous improvement)
•Effort/impact quadrant
•Quick wins identification
•Strategic investments

6.6 Output Selection

Based on output_format parameter:

•executive: Executive Summary only
•debt_roadmap_only: Technical Debt Roadmap only

Techniques Used:

•artifact_synthesis - Compile structured output
•health_score_calculation - Compute architecture health
•stakeholder_communication - Tailor for audience

Quality Gate: Output validates against CONTRACT-07 schema with architecture extensions

Output: GAP-INVENTORY artifact + Architecture Health Score + requested summaries

5. Gap Taxonomy

The 6 Gap Types

#	Type	Definition	Architecture Detection Signal	Remediation
1	MISSING	Required element completely absent	No viewpoint coverage, no ADRs found, deployment undocumented	Add content
2	INCOMPLETE	Present but lacking required detail	TBD in diagrams, partial API specs, rationale missing	Expand content
3	INCONSISTENT	Contradicts other sections	Context shows 5 services, container shows 8; ADR contradicts implementation	Reconcile content
4	AMBIGUOUS	Multiple interpretations possible	"Scalable architecture" without metrics, "secure by design" without controls	Clarify content
5	INCORRECT	Technically wrong information	References deprecated API, shows removed service, wrong technology	Correct content
6	OUTDATED	Was correct but no longer current	Shows v1 API when v3 current, references decommissioned database	Update content

Reference: See references/architecture-checklist.md for detailed detection heuristics per checklist item.

9. Behavioral Guidelines

•Systematic not judgmental: Report gaps objectively, not as criticism
•Evidence-based: Every gap must have cited evidence from the document
•Constructive: Focus on remediation, not just problems
•Calibrated: Severity reflects actual implementation impact
•Complete: Check every applicable item, don't skip viewpoints
•Framework-aware: Respect the architecture methodology being used
•Debt-conscious: Surface technical debt signals for proactive management
•Actionable: Every gap should have a clear path to resolution
