Skill: Spec Traceability

Overview

This skill generates traceability matrices:

• Map requirements to test cases
• Identify coverage gaps
• Calculate coverage percentages
• Generate compliance reports

Purpose

Ensure complete test coverage of requirements. Use this skill:

• Before releases
• During audits
• For compliance validation
• When requirements change

Execution Flow

1. PARSE requirement documents
2. PARSE test specifications
3. EXTRACT requirement IDs
4. MAP tests to requirements
5. CALCULATE coverage metrics
6. IDENTIFY gaps
7. GENERATE matrix report

Input Parameters

Parameter	Type	Description	Required
requirementsPath	string	Path to requirements doc	No
testsPath	string	Path to test files	No
threshold	number	Minimum coverage %	No
format	string	matrix, list, graph	No

Output Format

# Traceability Matrix Report

**Generated:** [timestamp]
**Source:** docs/requirements.md
**Tests:** tests/**/*.spec.ts

## Summary

| Metric | Value |
|--------|-------|
| Total Requirements | 24 |
| Covered Requirements | 21 |
| Coverage Percentage | 87.5% |
| Gaps | 3 |
| Orphan Tests | 2 |

## Coverage by Priority

| Priority | Total | Covered | Coverage |
|----------|-------|---------|----------|
| P1 - Critical | 8 | 8 | 100% |
| P2 - High | 6 | 5 | 83% |
| P3 - Medium | 6 | 5 | 83% |
| P4 - Low | 4 | 3 | 75% |

## Detailed Matrix

### Requirements → Tests

| Req ID | Requirement | Test Cases | Coverage |
|--------|-------------|------------|----------|
| REQ-001 | User login | TC-001, TC-002 | ✅ Full |
| REQ-002 | Password reset | TC-003 | ⚠️ Partial |
| REQ-003 | Session timeout | - | ❌ Gap |
| REQ-004 | SSO integration | TC-004, TC-005, TC-006 | ✅ Full |

### Tests → Requirements

| Test ID | Test Description | Requirements |
|---------|------------------|--------------|
| TC-001 | Login with valid credentials | REQ-001 |
| TC-002 | Login with invalid credentials | REQ-001 |
| TC-003 | Password reset email | REQ-002 |
| TC-004 | SSO redirect | REQ-004 |

## Gap Analysis

### Uncovered Requirements

1. **REQ-003: Session Timeout**
   - Priority: P1 - Critical
   - Risk: High
   - Suggested Tests:
     - TC-NEW-1: Verify 30-minute timeout
     - TC-NEW-2: Verify session refresh
     - TC-NEW-3: Verify timeout warning

2. **REQ-010: Bulk User Import**
   - Priority: P2 - High
   - Risk: Medium
   - Suggested Tests:
     - TC-NEW-4: CSV import
     - TC-NEW-5: Error handling

### Orphan Tests (No Requirements)

| Test ID | Description | Recommendation |
|---------|-------------|----------------|
| TC-099 | Helper utility | Remove or document |
| TC-100 | Edge case | Link to requirement |

## Compliance Status

| Standard | Requirement | Status |
|----------|-------------|--------|
| ISO 27001 | A.14.2.9 | ⚠️ Partial |
| SOC 2 | CC8.1 | ✅ Compliant |
| GDPR | Art. 32 | ⚠️ Partial |

## Recommendations

1. **Critical:** Add tests for REQ-003 (Session Timeout)
2. **High:** Complete coverage for REQ-010 (Bulk Import)
3. **Medium:** Link or remove orphan tests
4. **Documentation:** Update spec comments

Example Usage

Example 1: Generate Full Matrix

USER: /spec-traceability

SKILL OUTPUT:
# Traceability Matrix Report

## Summary
- Total Requirements: 24
- Covered: 21 (87.5%)
- Gaps: 3

## Critical Gaps
1. REQ-003: Session Timeout (P1)
2. REQ-010: Bulk Import (P2)
3. REQ-022: Audit Log (P3)

**Action Required:** Add 8 tests to reach 100% coverage

Example 2: Coverage by Category

USER: /spec-traceability --by-category

SKILL OUTPUT:
# Coverage by Category

| Category | Total | Covered | % |
|----------|-------|---------|---|
| Authentication | 5 | 5 | 100% |
| User Management | 6 | 5 | 83% |
| Payments | 4 | 4 | 100% |
| Reporting | 5 | 4 | 80% |
| Admin | 4 | 3 | 75% |

**Lowest Coverage:** Admin (75%)
**Recommendation:** Focus testing on Admin features

Example 3: Compliance Report

USER: /spec-traceability --compliance SOC2

SKILL OUTPUT:
# SOC 2 Compliance Report

## Control Coverage

| Control | Requirement | Tests | Status |
|---------|-------------|-------|--------|
| CC6.1 | Access Control | TC-001-005 | ✅ |
| CC6.6 | Security | TC-010-015 | ✅ |
| CC7.1 | Monitoring | TC-020-025 | ⚠️ |
| CC8.1 | Change Mgmt | TC-030-035 | ✅ |

## Compliance Status: 87.5%

⚠️ **Warning:** CC7.1 Monitoring incomplete
- Missing: Log retention tests
- Missing: Alert tests

**Remediation:** Add TC-NEW-6, TC-NEW-7 for CC7.1

Best Practices

1. Consistent IDs - Use standard ID patterns
2. Bidirectional Links - Tag tests AND requirements
3. Regular Updates - Regenerate matrix on changes
4. Gap Prioritization - Focus on high-risk gaps
5. Automation - Run in CI/CD pipelines

Integration

This skill integrates with:

• coverage-analysis: Combined test coverage
• spec-validation: Validate spec completeness
• Jira/Azure DevOps: Import requirements
• TestRail/Zephyr: Export test mappings
