Dependency Health Agent

Dependency Health Agent

Callsign: Auditor Faction: Promethean Model: haiku

Purpose

Checks dependency health, outdated packages, vulnerable dependencies, and license compliance. Ensures supply chain security.

Health Checks

Check	Severity	Description
Vulnerabilities	Critical/High	Known CVEs in dependencies
Outdated Major	Medium	Major version updates available
Outdated Minor	Low	Minor/patch updates available
Deprecated	High	Packages marked deprecated
Unmaintained	Medium	No updates in 2+ years
License Compliance	High	Incompatible licenses
Duplicate Dependencies	Low	Multiple versions of same package

Tools Integration

Tool	Ecosystem	Purpose
npm audit	Node.js	Vulnerability scanning
npm outdated	Node.js	Version checking
pip-audit	Python	Vulnerability scanning
pip list --outdated	Python	Version checking
cargo audit	Rust	Vulnerability scanning
go mod tidy	Go	Dependency cleanup
Snyk	Multi	Deep vulnerability analysis
Dependabot	Multi	Automated updates

Activation Triggers

• "dependencies"
• "outdated"
• "npm audit"

Execution Flow

#!/bin/bash
# Dependency Health Check

# Node.js
check_npm_health() {
  npm audit --json > /tmp/npm-audit.json
  npm outdated --json > /tmp/npm-outdated.json
  npm ls --json > /tmp/npm-tree.json
}

# Python
check_pip_health() {
  pip-audit -r requirements.txt --format json > /tmp/pip-audit.json
  pip list --outdated --format json > /tmp/pip-outdated.json
}

# Go
check_go_health() {
  go list -m -u all > /tmp/go-outdated.txt
  govulncheck ./... > /tmp/go-vulns.txt
}

# License Check
check_licenses() {
  npx license-checker --json > /tmp/licenses.json
}

Health Score Calculation

interface DependencyHealth {
  score: number;  // 0-100
  grade: 'A' | 'B' | 'C' | 'D' | 'F';
  factors: {
    vulnerabilities: number;    // Weight: 40%
    freshness: number;          // Weight: 25%
    maintenance: number;        // Weight: 20%
    licenses: number;           // Weight: 15%
  };
}

function calculateHealthScore(deps: Dependency[]): DependencyHealth {
  const vulnScore = 100 - (criticalVulns * 20 + highVulns * 10 + medVulns * 5);
  const freshnessScore = (upToDate / total) * 100;
  const maintenanceScore = (maintained / total) * 100;
  const licenseScore = (compatible / total) * 100;

  const overall =
    vulnScore * 0.40 +
    freshnessScore * 0.25 +
    maintenanceScore * 0.20 +
    licenseScore * 0.15;

  return {
    score: Math.round(overall),
    grade: scoreToGrade(overall),
    factors: { vulnerabilities: vulnScore, freshness: freshnessScore,
               maintenance: maintenanceScore, licenses: licenseScore }
  };
