name: dependency-audit description: Audit npm dependencies for security vulnerabilities, outdated packages, unused deps, license compliance, and bundle impact. Use regularly for security hygiene, before major releases, or when bundle size grows unexpectedly.

Dependency Audit

Comprehensive audit of project dependencies for security, maintenance, and efficiency.

Scope

1. Security Vulnerabilities

• Run npm audit for known vulnerabilities
• Check severity levels (critical, high, medium, low)
• Identify transitive dependency risks
• Review Dependabot/security advisories if available

2. Outdated Packages

• Compare current vs latest versions
• Identify packages with major version gaps
• Check for deprecated packages
• Review changelogs for breaking changes

3. Unused Dependencies

• Dependencies in package.json not imported anywhere
• devDependencies that should be dependencies (or vice versa)
• Duplicate functionality (multiple packages doing same thing)
• Per AGENTS.md: "Remove unused deps promptly"

4. License Compliance

• Identify licenses of all dependencies
• Flag copyleft licenses (GPL, AGPL) if problematic
• Check for license compatibility
• Document any commercial license requirements

5. Bundle Impact Analysis

• Large dependencies affecting client bundle
• Dependencies that should be dynamically imported
• Server-only packages accidentally in client bundle
• Tree-shaking effectiveness

6. Supply Chain Risk

• Packages with very few maintainers
• Packages with no recent updates (abandoned)
• Packages with suspicious update patterns
• Typosquatting risks

7. Core Dependency Health (project-specific)

Check health of key dependencies:

• Next.js - Framework updates, security patches
• Drizzle ORM - Database layer stability
• Supabase client - Auth/storage compatibility
• TanStack Query - Caching layer
• Radix UI / shadcn - Component primitives
• TipTap - Rich text editor
• dnd-kit - Drag and drop
• date-fns - Date handling
• Zod - Validation schemas

Actions

1. Run npm audit and capture output
2. Run npm outdated to list version gaps
3. Search for unused imports with grep patterns
4. Check package.json against actual imports
5. Analyze bundle with build output

Output Format

Security Findings

Copy[SEVERITY: CRITICAL|HIGH|MEDIUM|LOW]
Package: package-name@version
Vulnerability: CVE or advisory ID
Description: What the vulnerability allows
Fix: Upgrade path or mitigation

Outdated Packages

CopyPackage: package-name
Current: x.y.z
Latest: a.b.c
Risk: Breaking changes likelihood
Action: Upgrade/Hold/Investigate

Unused Dependencies

CopyPackage: package-name
Type: dependency|devDependency
Evidence: Not found in codebase
Action: Remove from package.json

Bundle Impact

CopyPackage: package-name
Size: XXkB (gzipped)
Location: client|server|both
Issue: Should be server-only / dynamically imported

Dependency Management Rules (from AGENTS.md)

• Install via npm install <package>@latest
• Record rationale in PRs
• Remove unused deps promptly
• Do not edit package.json or lockfiles directly (use CLI)

Post-Audit

Generate:

• Security remediation priority list
• Safe upgrade commands
• Packages to remove
• Bundle optimization opportunities
• Maintenance risk assessment
