What it does

Dependency Auditor is an agent skill from OneWave-AI/claude-skills. Audit npm dependencies for security vulnerabilities, outdated packages, and unused dependencies. Use when checking for security issues, updating packages, or cleaning up dependencies.

Its SKILL.md is about 840 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Security. It works with npm. The repository describes itself as: 200+ production-ready Claude Code skills for sales, marketing, design, engineering, and AI agent architecture. Built and maintained by OneWave AI. The licence is MIT.

When your agent uses it

  • Checking for security issues
  • Updating packages
  • Cleaning up dependencies

Example prompts

  • “/dependency-auditor”

Requirements

  • Node.js

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Run security audit
  2. Check for outdated packages
  3. Find unused dependencies
  4. Analyze bundle size impact
  5. Review and update

What it can do on your machine

Read from SKILL.md and the folder at commit fc5b785. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm
    • npx
    • pnpm
    • yarn

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npm, npx, pnpm and yarn, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Dependency Auditor loads about 835 tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 165 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~51
When it runs · the whole SKILL.md, loaded when a task matches
~835

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Dependency Auditor

Instructions

When auditing dependencies:

  1. Run security audit
  2. Check for outdated packages
  3. Find unused dependencies
  4. Analyze bundle size impact
  5. Review and update

Security Audit

bash
# NPM audit
npm audit

# Get JSON output for processing
npm audit --json

# Fix automatically (safe fixes only)
npm audit fix

# Force fix (may have breaking changes)
npm audit fix --force

# PNPM
pnpm audit

# Yarn
yarn audit

Check Outdated Packages

bash
# NPM
npm outdated

# Interactive update
npx npm-check-updates -i

# Update all to latest
npx npm-check-updates -u
npm install

# Check specific package
npm view <package> versions

Find Unused Dependencies

bash
# Using depcheck
npx depcheck

# With details
npx depcheck --detailed

# Ignore patterns
npx depcheck --ignores="@types/*,eslint-*"
Common False Positives

Depcheck may flag these as unused when they're actually needed:

  • @types/* packages (used by TypeScript)
  • ESLint/Prettier plugins (referenced in config)
  • PostCSS plugins (referenced in config)
  • Next.js plugins
  • Babel presets

Analyze Bundle Size

bash
# For Next.js
npx @next/bundle-analyzer

# General purpose
npx source-map-explorer dist/**/*.js

# Check package size before installing
npx package-phobia <package-name>

# Compare alternatives
npx bundlephobia-cli compare lodash ramda

Dependency Review Checklist

Security
  • No critical/high vulnerabilities
  • Dependencies actively maintained
  • No known malicious packages
  • Lock file committed
Freshness
  • No major version behind (unless intentional)
  • Security patches applied
  • Deprecated packages replaced
Cleanliness
  • No unused dependencies
  • No duplicate packages (check lock file)
  • devDependencies vs dependencies correct

Update Strategies

bash
# Update patch versions only
npm update

# Update specific package
npm install package@latest
Aggressive
bash
# Update everything
npx npm-check-updates -u
npm install
npm test
Interactive
bash
npx npm-check-updates -i

# Options:
# a - update all
# space - toggle selection
# enter - apply selected

Package.json Cleanup

json
{
  "dependencies": {
    // Runtime dependencies only
  },
  "devDependencies": {
    // Build/test tools only
  },
  "peerDependencies": {
    // For libraries only
  },
  "optionalDependencies": {
    // Platform-specific (rare)
  }
}

Lock File Best Practices

  1. Always commit lock files (package-lock.json, pnpm-lock.yaml, yarn.lock)
  2. Use npm ci in CI/CD (not npm install)
  3. Regenerate if corrupted: delete lock file + node_modules, reinstall
  4. Single lock file per project (don't mix package managers)

Automated Monitoring

yaml
# .github/dependabot.yml
version: 2
updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
    open-pull-requests-limit: 10
    groups:
      dev-dependencies:
        dependency-type: "development"
