Dependency Audit Skill

Summary

Systematic workflow for auditing, updating, and cleaning up project dependencies. Covers security vulnerability scanning, outdated package detection, unused dependency removal, and migration from deprecated libraries.

When to Use

• Weekly/monthly dependency maintenance
• After security advisories (CVE announcements)
• Before major releases
• When bundle size increases unexpectedly
• During code reviews for dependency changes
• Onboarding to legacy projects

Quick Audit Process

1. Check Outdated Packages

# npm
npm outdated

# pnpm
pnpm outdated

# yarn
yarn outdated

# pip (Python)
pip list --outdated

# poetry (Python)
poetry show --outdated

2. Security Vulnerability Scan

# npm
npm audit
npm audit fix          # Auto-fix where possible
npm audit fix --force  # Force major version updates (risky)

# pnpm
pnpm audit
pnpm audit --fix

# yarn
yarn audit
yarn audit --fix

# Python
pip-audit              # Requires: pip install pip-audit
safety check           # Requires: pip install safety

3. Find Unused Dependencies

# JavaScript/TypeScript
npx depcheck

# Output example:
# Unused dependencies
# * lodash
# * moment
# Unused devDependencies
# * @types/old-package

# Python
pip-autoremove --list  # Requires: pip install pip-autoremove
