Step 4E: Aggregate NFR Assessment Results

STEP GOAL

Read outputs from 4 parallel NFR subagents, calculate overall risk level, aggregate compliance status, and identify cross-domain risks.

---

MANDATORY EXECUTION RULES

• 📖 Read the entire step file before acting
• ✅ Speak in {communication_language}
• ✅ Read all 4 subagent outputs
• ✅ Calculate overall risk level
• ❌ Do NOT re-assess NFRs (use subagent outputs)

---

MANDATORY SEQUENCE

1. Read All Subagent Outputs

const domains = ['security', 'performance', 'reliability', 'scalability'];
const assessments = {};

domains.forEach((domain) => {
  const outputPath = `/tmp/tea-nfr-${domain}-{{timestamp}}.json`;
  assessments[domain] = JSON.parse(fs.readFileSync(outputPath, 'utf8'));
});

---

2. Calculate Overall Risk Level

Risk hierarchy: HIGH > MEDIUM > LOW > NONE

const riskLevels = { HIGH: 3, MEDIUM: 2, LOW: 1, NONE: 0 };
const domainRisks = domains.map((d) => assessments[d].risk_level);
const maxRiskValue = Math.max(...domainRisks.map((r) => riskLevels[r]));
const overallRisk = Object.keys(riskLevels).find((k) => riskLevels[k] === maxRiskValue);

Risk assessment:

• If ANY domain is HIGH → overall is HIGH
• If ANY domain is MEDIUM (and none HIGH) → overall is MEDIUM
• If ALL domains are LOW/NONE → overall is LOW

---

3. Aggregate Compliance Status

const allCompliance = {};

domains.forEach((domain) => {
  const compliance = assessments[domain].compliance;
  Object.entries(compliance).forEach(([standard, status]) => {
    if (!allCompliance[standard]) {
      allCompliance[standard] = [];
    }
    allCompliance[standard].push({ domain, status });
  });
});

// Determine overall compliance per standard
const complianceSummary = {};
Object.entries(allCompliance).forEach(([standard, statuses]) => {
  const hasFail = statuses.some((s) => s.status === 'FAIL');
  const hasPartial = statuses.some((s) => s.status === 'PARTIAL' || s.status === 'CONCERN');

  complianceSummary[standard] = hasFail ? 'FAIL' : hasPartial ? 'PARTIAL' : 'PASS';
});

---

4. Identify Cross-Domain Risks

Look for risks that span multiple domains:

const crossDomainRisks = [];

// Example: Performance + Scalability issue
const perfConcerns = assessments.performance.findings.filter((f) => f.status !== 'PASS');
const scaleConcerns = assessments.scalability.findings.filter((f) => f.status !== 'PASS');
if (perfConcerns.length > 0 && scaleConcerns.length > 0) {
  crossDomainRisks.push({
    domains: ['performance', 'scalability'],
    description: 'Performance issues may worsen under scale',
    impact: 'HIGH',
  });
}

// Example: Security + Reliability issue
const securityFails = assessments.security.findings.filter((f) => f.status === 'FAIL');
const reliabilityConcerns = assessments.reliability.findings.filter((f) => f.status !== 'PASS');
if (securityFails.length > 0 && reliabilityConcerns.length > 0) {
  crossDomainRisks.push({
    domains: ['security', 'reliability'],
    description: 'Security vulnerabilities may cause reliability incidents',
    impact: 'CRITICAL',
  });
}

---

5. Aggregate Priority Actions

const allPriorityActions = domains.flatMap((domain) =>
  assessments[domain].priority_actions.map((action) => ({
    domain,
    action,
    urgency: assessments[domain].risk_level === 'HIGH' ? 'URGENT' : 'NORMAL',
  })),
);

// Sort by urgency
const prioritizedActions = allPriorityActions.sort((a, b) => (a.urgency === 'URGENT' ? -1 : 1));

---

6. Generate Executive Summary

const resolvedMode = subagentContext?.execution?.resolvedMode ?? 'unknown';
const subagentExecutionLabel =
  resolvedMode === 'sequential'
    ? 'SEQUENTIAL (4 NFR domains)'
    : resolvedMode === 'agent-team'
      ? 'AGENT-TEAM (4 NFR domains)'
      : resolvedMode === 'subagent'
        ? 'SUBAGENT (4 NFR domains)'
        : 'MODE-DEPENDENT (4 NFR domains)';

const performanceGainLabel =
  resolvedMode === 'sequential'
    ? 'baseline (no parallel speedup)'
    : resolvedMode === 'agent-team' || resolvedMode === 'subagent'
      ? '~67% faster than sequential'
      : 'mode-dependent';

const executiveSummary = {
  overall_risk: overallRisk,
  assessment_date: new Date().toISOString(),

  domain_assessments: assessments,

  compliance_summary: complianceSummary,

  cross_domain_risks: crossDomainRisks,

  priority_actions: prioritizedActions,

  risk_breakdown: {
    security: assessments.security.risk_level,
    performance: assessments.performance.risk_level,
    reliability: assessments.reliability.risk_level,
    scalability: assessments.scalability.risk_level,
  },

  subagent_execution: subagentExecutionLabel,
  performance_gain: performanceGainLabel,
};

// Save for Step 5 (report generation)
fs.writeFileSync('/tmp/tea-nfr-summary-{{timestamp}}.json', JSON.stringify(executiveSummary, null, 2), 'utf8');

---

7. Display Summary to User

✅ NFR Assessment Complete ({subagentExecutionLabel})

🎯 Overall Risk Level: {overallRisk}

📊 Domain Risk Breakdown:
- Security:      {security_risk}
- Performance:   {performance_risk}
- Reliability:   {reliability_risk}
- Scalability:   {scalability_risk}

✅ Compliance Summary:
{list standards with PASS/PARTIAL/FAIL}

⚠️ Cross-Domain Risks: {cross_domain_risk_count}

🎯 Priority Actions: {priority_action_count}

🚀 Performance: {performanceGainLabel}

✅ Ready for report generation (Step 5)

8. Save Progress

Save this step's accumulated work to {outputFile}.

• If {outputFile} does not exist (first save), create it using the workflow template (if available) with YAML frontmatter:

  ---
  stepsCompleted: ['step-04e-aggregate-nfr']
  lastStep: 'step-04e-aggregate-nfr'
  lastSaved: '{date}'
  ---
  

  Then write this step's output below the frontmatter.

• If {outputFile} already exists, update:

  • Add 'step-04e-aggregate-nfr' to stepsCompleted array (only if not already present)
  • Set lastStep: 'step-04e-aggregate-nfr'
  • Set lastSaved: '{date}'
  • Append this step's output to the appropriate section of the document.

---

EXIT CONDITION

Proceed to Step 5 when:

• ✅ All subagent outputs read
• ✅ Overall risk calculated
• ✅ Compliance aggregated
• ✅ Summary saved
• ✅ Progress saved to output document

Load next step: {nextStepFile}

🚨 SYSTEM SUCCESS METRICS

✅ SUCCESS:

• All 4 NFR domains aggregated correctly
• Overall risk level determined
• Executive summary complete

❌ FAILURE:

• Failed to read subagent outputs
• Risk calculation incorrect
