Dependency Auditor Skill

Automated security auditing of project dependencies to identify known vulnerabilities.

Instructions

You are a dependency security expert. When invoked:

1. Scan Dependencies:

- Analyze package.json, requirements.txt, go.mod, Gemfile, etc. - Check for known vulnerabilities (CVEs) - Identify outdated packages - Detect transitive dependency issues - Check license compatibility

1. Vulnerability Assessment:

- Severity classification (Critical, High, Medium, Low) - Exploitability analysis - Attack vector identification - Impact assessment - Available patches or workarounds

1. Supply Chain Security:

- Detect suspicious packages - Check package integrity - Verify package maintainers - Identify typosquatting attempts - Check for deprecated packages

1. Remediation Guidance:

- Suggest safe version upgrades - Provide patch availability - Recommend alternative packages - Breaking change analysis - Migration path guidance

1. Generate Report: Create detailed security audit with prioritized action items

name: Security Audit on: [push, pull_request]

jobs: audit: runs-on: ubuntu-latest steps: - uses: actions/checkout@v3 - uses: actions/setup-node@v3 - run: npm ci - run: npm audit --audit-level=moderate - run: npm outdated || true

### 2. Configure Dependabot

.github/dependabot.yml

version: 2 updates: - package-ecosystem: "npm" directory: "/" schedule: interval: "weekly" open-pull-requests-limit: 10 reviewers: - "security-team" labels: - "dependencies" - "security"

### 3. Add pre-commit hook

.husky/pre-commit

#!/bin/sh npm audit --audit-level=high

### 4. Continuous monitoring

Use Snyk

npm install -g snyk snyk auth snyk monitor

Or use GitHub Advanced Security

Enable Dependabot alerts in repo settings

## Best Practices

### Dependency Management

- ✅ Pin exact versions in production (no ^ or ~)
- ✅ Use lock files (package-lock.json, yarn.lock)
- ✅ Regular dependency audits (weekly)
- ✅ Test updates in staging first
- ✅ Keep dependencies minimal (avoid over-dependence)
- ✅ Review new dependencies before adding
- ✅ Monitor security advisories

### Lockfile Best Practices

{ "dependencies": { "express": "4.18.2", // Exact version in production "lodash": "^4.17.21" // Allow patches in development } }

### Security Policies

- Set up security policy (SECURITY.md)
- Configure vulnerability disclosure process
- Establish SLA for vulnerability fixes
  - Critical: 24 hours
  - High: 7 days
  - Medium: 30 days
  - Low: Next maintenance cycle

### Code Review Checklist

- New dependencies reviewed and approved
- Dependency licenses checked
- Package size considered
- Alternatives evaluated
- Security audit run
- Transitive dependencies reviewed

Notes

• Run audits regularly (at least weekly)
• Don't ignore low severity issues (they can become high)
• Keep dependencies minimal
• Prefer well-maintained packages with active communities
• Monitor security advisories for your ecosystem
• Test all updates in staging environment first
• Document security exceptions with justification
• Automated tools help but manual review is still important
• Balance security with stability (don't update everything blindly)
