Audit Aggregator

Audit Aggregator Agent

Purpose: Merge findings from 6+ domain-specific audit reports into a single comprehensive, priority-ranked report with cross-domain insights and deduplication.

Input: Multiple audit report files (markdown format) Output: COMPREHENSIVE_AUDIT_REPORT.md with executive summary, priority rankings, and cross-cutting analysis

Input Requirements

Expected Files:

• docs/audits/comprehensive/audit-code-report.md
• docs/audits/comprehensive/audit-security-report.md
• docs/audits/comprehensive/audit-performance-report.md
• docs/audits/comprehensive/audit-documentation-report.md
• docs/audits/comprehensive/audit-refactoring-report.md
• docs/audits/comprehensive/audit-process-report.md

Required Format (in each report):

Each individual audit report should contain findings in this structure:

## Findings

### [ID] [Title] (Severity: S0-S3, Effort: E0-E3, Confidence: High/Medium/Low)

**File:** `path/to/file.ts:123` **Category:** [Category Name] **Description:**
[Detailed description] **Evidence:** [Code snippets, metrics, etc.]
**Recommendation:** [How to fix]

Processing Steps

Step 1: Parse All Reports

Read all 6 audit reports and extract findings into structured format:

{
  id: "CODE-001",
  title: "Missing error handling",
  severity: "S1",
  effort: "E1",
  confidence: "High",
  file: "src/auth.ts",
  line: 45,
  category: "Code Quality",
  domain: "code",
  description: "...",
  evidence: "...",
  recommendation: "..."
}

Parsing Rules:

• ID Format: {DOMAIN}-{NUMBER} (e.g., CODE-001, SEC-012, PERF-003)
• Severity: S0 (Critical) > S1 (High) > S2 (Medium) > S3 (Low)
• Effort: E0 (Trivial) < E1 (Hours) < E2 (Day) < E3 (Major)
• Confidence: High > Medium > Low (affects priority weighting)
• File:Line: Extract from "File: `path/to/file.ts:123`" format

Handle Missing Fields:

• If severity missing → assume S2 (Medium)
• If effort missing → assume E1 (Hours)
• If confidence missing → assume Medium
• If file:line missing → categorize as "General" finding

Step 2: Deduplicate Findings

Deduplication Logic:

Group findings by (file, line) pair:

// Pseudo-code
const groups = groupBy(findings, (f) => `${f.file}:${f.line}`);

for (const group of groups) {
  if (group.length > 1) {
    // Multiple audits flagged same location
    merged = {
      id: `COMP-${nextId++}`, // New composite ID
      domains: group.map((f) => f.domain), // ["code", "security"]
      severity: maxSeverity(group), // Take worst severity
      effort: maxEffort(group), // Take highest effort estimate
      confidence: maxConfidence(group), // Take highest confidence
      title: mergeTitles(group), // Combine titles
      description: mergeDescriptions(group), // Combine contexts
      category: "Cross-Domain", // Flag as spanning multiple domains
      ...
    };
  }
}

Merge Rules:

• Severity: Take worst (S0 > S1 > S2 > S3)
• Effort: Take highest (E3 > E2 > E1 > E0)
• Confidence: Take highest (High > Medium > Low)
• Title: Combine unique titles (e.g., "Missing error handling + Exception vulnerability")
• Description: Concatenate all descriptions with domain labels
• Category: Change to "Cross-Domain" if 2+ domains

Example Deduplication:

Before:
  CODE-001: Missing error handling (S1, E1) at auth.ts:45
  SEC-012: Exception vulnerability (S0, E1) at auth.ts:45

After:
  COMP-001: Missing error handling + Exception vulnerability (S0, E1, Domains: 2)
    Category: Cross-Domain (Code + Security)

Step 3: Identify Cross-Cutting Patterns

Pattern Detection:

A. Hotspot Files (appear in 3+ audits):

// Count how many audits mention each file
const fileCounts = {};
for (const finding of findings) {
  fileCounts[finding.file] = (fileCounts[finding.file] || 0) + 1;
}

// Files with 3+ mentions
const hotspots = Object.entries(fileCounts)
  .filter(([file, count]) => count >= 3)
  .sort((a, b) => b[1] - a[1]);

B. Related Findings (fixing one helps another):

Look for pairs where:

• Same file, different concerns (e.g., performance + security in same function)
• Dependency chain (e.g., missing docs for complex code)
• Contradiction patterns (e.g., over-engineered simple function)

C. Domain Overlaps:

Count overlaps between domain pairs:

Security + Performance: 12 findings
Code + Refactoring: 18 findings
Documentation + Code: 8 findings

D. Category Patterns:

Group by category across domains:

Authentication: 5 findings (2 security, 2 code, 1 process)
Error Handling: 8 findings (3 code, 3 security, 2 performance)
Testing: 12 findings (6 code, 4 refactoring, 2 process)

Step 4: Priority Ranking

Priority Score Formula:

priority = severityWeight × crossDomainMultiplier × confidenceWeight / effortWeight;

// Weights
severityWeight = { S0: 100, S1: 50, S2: 20, S3: 5 };
crossDomainMultiplier = 1 + (domains.length - 1) * 0.5; // 1.0, 1.5, 2.0, 2.5...
confidenceWeight = { High: 1.0, Medium: 0.8, Low: 0.5 };
effortWeight = { E0: 0.5, E1: 1.0, E2: 2.0, E3: 4.0 };

Ranking Rules:

1. S0 Critical always rank first (regardless of other factors)
2. Cross-domain findings bubble up (multiplier effect)
3. High confidence preferred over low confidence
4. Low effort (quick wins) preferred when severity equal

Example Scores:

Finding A: S0 Critical, 1 domain, High confidence, E1 effort
  → 100 × 1.0 × 1.0 / 1.0 = 100 (Rank #1)

Finding B: S1 High, 3 domains, High confidence, E1 effort
  → 50 × 2.0 × 1.0 / 1.0 = 100 (Rank #2 - tie, resolved by severity S0 > S1)

Finding C: S2 Medium, 2 domains, High confidence, E0 trivial
  → 20 × 1.5 × 1.0 / 0.5 = 60 (Rank #3 - quick win)

Finding D: S1 High, 1 domain, Medium confidence, E2 day
  → 50 × 1.0 × 0.8 / 2.0 = 20 (Rank #4 - high effort lowers priority)

Step 5: Generate Executive Summary

Summary Components:

A. Statistics:

## Executive Summary

### Audit Overview

- **Raw Findings:** 142 (across 6 audits)
- **Unique Findings:** 97 (after deduplication)
- **Merged Findings:** 45 (appeared in 2+ audits)
- **Cross-Domain Findings:** 18 (3+ audits)

### Severity Breakdown

- **S0 Critical:** 3 (IMMEDIATE ACTION REQUIRED)
- **S1 High:** 24 (fix within sprint)
- **S2 Medium:** 42 (plan for next milestone)
- **S3 Low:** 28 (backlog/nice-to-have)

B. Top Insights:

List 3-5 highest-impact insights:

### Key Insights

1. **Authentication Layer Needs Comprehensive Refactor**
   - 8 files appear in 4+ audits (security, code, performance, documentation)
   - High complexity with poor error handling and missing tests
   - Recommended: Dedicated sprint to harden auth module

2. **Security + Performance Overlap**
   - 12 findings where fixing security also improves performance
   - Example: Rate limiting prevents DoS (security) + reduces server load
     (performance)
   - Recommended: Bundle these fixes together

3. **Documentation Gaps Align with Code Complexity**
   - 5 files with S1 complexity issues also have missing/outdated docs
   - Difficult to maintain or extend without documentation
   - Recommended: Document complex areas first (highest ROI)

C. Recommended Fix Order:

### Recommended Action Plan

**Phase 1: Critical Fixes (Week 1)**

1. FIX S0 findings (3 items - 8 hours)
2. Address top 5 quick wins (E0 - 4 hours)

**Phase 2: High-Priority Fixes (Week 2-3)**

1. Cross-domain findings (18 items - 32 hours)
2. Hotspot files refactor (8 files - 48 hours)

**Phase 3: Systematic Improvements (Month 2)**

1. Remaining S1 findings (21 items - 36 hours)
2. S2 medium-effort fixes (28 items - 56 hours)

**Phase 4: Backlog (Ongoing)**

1. S3 low-priority (28 items - 24 hours)
2. Major refactors (E3 - 96 hours, spread over quarters)

Output Validation

Before Finalizing Report:

1. Verify deduplication worked:

   • Count unique findings vs raw findings
   • Ensure merged findings have correct domain lists
   • No duplicate file:line pairs

2. Verify priority ranking:

   • Top 20 should have highest scores
   • S0 Critical should all be in top 20
   • Cross-domain findings should rank higher than single-domain

3. Verify cross-cutting insights:

   • Hotspot files should have 3+ mentions
   • Domain overlaps should be accurate counts
   • Category patterns should group related findings

4. Verify completeness:

   • All raw findings accounted for (unique + duplicates = raw total)
   • All severity levels represented
   • All 6 audit reports linked in appendix

Error Handling

If Audit Report Missing:

• Note in report: "X audit not available"
• Continue with available audits
• Adjust statistics (e.g., "5 audits analyzed")

If Parsing Fails:

• Log which report/finding failed to parse
• Skip malformed finding
• Note in report: "X findings skipped due to format issues"

If Deduplication Produces Empty Result:

• Verify input reports aren't empty
• Check parsing logic
• Fall back to showing all findings without deduplication
