# gap-analysis

Unified gap analysis with natural language routing to specialized skills.

## Triggers

- "gap analysis"
- "find gaps"
- "what's missing"
- "what are we missing"
- "coverage gaps"
- "ready for audit"
- "audit gaps"
- "compliance gaps"
- "security gaps"
- "test gaps"
- "requirements gaps"

## Purpose

This skill provides a single entry point for all gap analysis needs by:
- Parsing natural language to understand analysis intent
- Routing to appropriate specialized skills
- Aggregating results into unified gap matrix
- Comparing to historical reports for trending
- Generating actionable remediation roadmaps

## Behavior

When triggered, this skill:

1. **Parse analysis intent**:
   - Extract analysis target from user request
   - Identify constraints (framework, phase, scope)
   - Determine focus (audit prep, release readiness, general health)
   - Handle compound requests ("security and coverage gaps")

2. **Route to specialized skills**:
   - Map intent to skill combination
   - Launch skills in parallel where possible
   - Pass relevant context to each skill

3. **Aggregate findings**:
   - Collect gap findings from all invoked skills
   - Normalize severity classification
   - Deduplicate overlapping findings
   - Generate stable gap IDs for tracking

4. **Compare to history**:
   - Detect previous reports with matching scope
   - Calculate delta (new gaps, closed gaps, unchanged)
   - Track gap age for unchanged items

5. **Generate unified report**:
   - Executive summary with key findings
   - Gap matrix with full details
   - Historical comparison section
   - Prioritized remediation roadmap

6. **Offer criteria saving** (if custom analysis):
   - Detect custom parameters used
   - Prompt user to save for reuse
   - Generate criteria YAML file

## Intent Extraction

### Analysis Targets

| Target | Keywords | Routes To |
|--------|----------|-----------|
| Security | security, vulnerabilities, OWASP, STRIDE, threat, attack | security-assessment |
| Compliance | SOC2, HIPAA, GDPR, PCI, ISO, compliance, audit, regulatory | flow-compliance-validation |
| Traceability | requirements, coverage, implemented, tested, orphan, traced | traceability-check |
| Test Coverage | test, coverage, untested, testing gaps | test-coverage |
| Gate Readiness | gate, transition, ready, phase, LOM, ABM, IOC, PRM | gate-evaluation |
| Workspace | workspace, artifacts, documentation, alignment, freshness | workspace-health |
| General | gaps, missing, issues, problems | traceability-check + workspace-health |

### Constraint Extraction

```yaml
constraint_patterns:
  framework:
    patterns: ["for (SOC2|HIPAA|GDPR|PCI-DSS|ISO27001)", "(SOC2|HIPAA|GDPR) audit"]
    maps_to: compliance_framework

  phase:
    patterns: ["for (Inception|Elaboration|Construction|Transition)", "before (Elaboration|Construction)"]
    maps_to: target_phase

  timeline:
    patterns: ["by (next week|end of month|Q[1-4])", "urgent", "before release"]
    maps_to: priority_boost

  scope:
    patterns: ["(auth|payment|api|database) module", "for (component|module) X"]
    maps_to: analysis_scope
```

### Compound Intent Handling

When multiple targets are detected:

```yaml
compound_routing:
  "security and compliance":
    skills: [security-assessment, flow-compliance-validation]
    execution: parallel

  "ready for SOC2 audit":
    skills:
      - security-assessment
      - flow-compliance-validation (framework: soc2)
      - traceability-check
    execution: parallel

  "full gap analysis":
    skills:
      - traceability-check
      - test-coverage
      - security-assessment
      - workspace-health
    execution: parallel
```

## Skill Integration

### Invocation Pattern

Each skill is invoked via Task tool with structured output requirements:

```
Task(
    subagent_type="{appropriate-agent}",
    description="Run {skill-name} gap analysis",
    prompt="""
    Execute {skill} analysis.

    Context:
    - Scope: {scope}
    - Focus: {focus}
    - Constraints: {constraints}

    Return findings in gap matrix format:
    - Gap ID: GA-{CATEGORY}-{HASH}
    - Category: {skill-category}
    - Severity: Critical/High/Medium/Low
    - Description: What is missing or wrong
    - Impact: Business/technical impact
    - Remediation: Specific action to close gap
    - Owner: Suggested owner (team or role)
    """
)
```

### Agent Assignments

| Skill | Invocation Agent |
|-------|------------------|
| traceability-check | requirements-analyst |
| security-assessment | security-architect |
| gate-evaluation | executive-orchestrator |
| test-coverage | test-architect |
| workspace-health | documentation-archivist |
| flow-compliance-validation | privacy-officer |

### Parallel Execution

```
Independent (parallel):
├── security-assessment
├── traceability-check
├── test-coverage
└── workspace-health

Sequential (after parallel complete):
├── gate-evaluation (may depend on other results)
└── Report synthesis (aggregates all findings)
```

## Severity Classification

### Unified Severity Levels

| Severity | Definition | Response SLA | Score |
|----------|------------|--------------|-------|
| Critical | Blocks production, high risk of immediate impact | 24-48 hours | 4 |
| High | Should block release, significant risk if unaddressed | 1-2 weeks | 3 |
| Medium | Address in near term, moderate risk | This quarter | 2 |
| Low | Address as capacity allows, minimal immediate risk | Backlog | 1 |

### Normalization Rules

```yaml
severity_mapping:
  # From security-assessment (CVSS)
  cvss_9.0+: Critical
  cvss_7.0-8.9: High
  cvss_4.0-6.9: Medium
  cvss_0.1-3.9: Low

  # From traceability-check
  orphan_critical_requirement: Critical
  orphan_requirement: High
  untested_critical_code: High
  untested_requirement: Medium
  untested_code: Medium
  rogue_code: Low

  # From gate-evaluation
  blocking_criteria: Critical
  conditional_criteria: High
  missing_artifact: Medium
  stale_artifact: Low

  # From test-coverage
  zero_coverage_critical_path: Critical
  below_50_critical: High
  below_threshold: Medium
  declining_coverage: Low
```

## Gap ID Generation

### Stable ID Format

`GA-{CATEGORY}-{HASH}`

Where:
- `CATEGORY`: SEC, TRC, CVR, CMP, ART (3-letter code)
- `HASH`: MD5 of identifying attributes, first 6 chars

### Hash Inputs by Category

```yaml
gap_id_inputs:
  security:
    hash_of: [file_path, vulnerability_type, location]
    example: "GA-SEC-a3f7b2"

  traceability:
    hash_of: [requirement_id, gap_type]
    example: "GA-TRC-c4e8d1"

  coverage:
    hash_of: [file_path, coverage_type]
    example: "GA-CVR-b2a9f0"

  compliance:
    hash_of: [framework, control_id]
    example: "GA-CMP-d7c3e5"

  artifact:
    hash_of: [artifact_type, artifact_name]
    example: "GA-ART-f1b8a4"
```

## Historical Comparison

### Report Detection

```yaml
historical_detection:
  report_pattern: ".aiwg/reports/gap-analysis-{scope}-*.md"

  scope_matching:
    exact: "gap-analysis-soc2-*.md" for SOC2 analysis
    fuzzy: "gap-analysis-security-*.md" includes security-focused
    general: "gap-analysis-full-*.md" for general analysis

  recency_preference:
    1. Most recent with matching scope
    2. Most recent with similar scope
    3. Skip comparison if no match
```

### Delta Calculation

```yaml
delta_algorithm:
  closed_gaps:
    definition: In previous report, not in current
    display: "Gaps Closed Since Last Report"

  new_gaps:
    definition: In current report, not in previous
    display: "New Gaps Since Last Report"

  unchanged_gaps:
    definition: In both reports
    tracking:
      - age_days: days since first detected
      - severity_change: severity in previous vs current
    display: "Unchanged Gaps (with age)"
```

### Trend Visualization

```markdown
### Trend Summary

| Metric | Previous | Current | Delta |
|--------|----------|---------|-------|
| Total Gaps | 15 | 12 | -3 ↓ |
| Critical | 2 | 1 | -1 ↓ |
