Dependency Auditor
Audit npm, pip, and Cargo dependencies for vulnerabilities, outdated packages, and license conflicts
What You Can Do
You can perform deep audits of your project dependencies across multiple package ecosystems, identifying security vulnerabilities with CVSS scores, outdated versions, license incompatibilities, and unused packages. The skill generates a prioritized upgrade roadmap that balances security urgency, stability risk, and effort cost—helping you reduce supply chain risk and technical debt without destabilizing production.
Features
Identifies known CVEs and exploits with severity ratings and remediation paths
Flags packages behind latest stable releases with upgrade compatibility info
Detects incompatible or restrictive licenses (GPL, proprietary, commercial mismatches)
Finds imported packages never referenced in code with confidence scoring
Ranks updates by security urgency, stability risk, and implementation effort
Maps circular and deep dependency chains for impact assessment
Audits npm (Node.js), pip (Python), and Cargo (Rust) in one pass
Provides staged update sequences, rollback procedures, and testing gates
Example Output
Example 1: Security Vulnerability Report
CRITICAL: lodash 4.17.15 → 4.17.21 (CVE-2021-23337)
CVSS Score: 9.1 | Prototype Pollution Exploit
Effort: Low (patch update, backward compatible)
Action: Upgrade immediately before next deploy
HIGH: express 4.16.2 → 4.18.2 (3 vulnerabilities)
CVSS Avg: 7.4 | Path traversal, DOS vectors
Effort: Medium (minor breaking changes in middleware)
Action: Stage in test environment, verify routing logic
Example 2: License Conflict Matrix
- ⚠️ GPL-3.0 (libpq) conflicts with proprietary license in main app
→ Recommendation: Replace with MIT/Apache-2.0 alternative
✓ MIT + Apache-2.0 + BSD licenses are compatible
Example 3: Unused Dependencies
unused-package (3.2.1) — Confidence: 98%
Last reference removed 6 months ago
Recommendation: Remove from package.json, save 2.4 MB
