Dependency Scan
Analyze package dependencies for known vulnerabilities.
Quick Start
/dependency-scan # Scan all detected package managers
/dependency-scan --npm # Node.js packages only
/dependency-scan --pip # Python packages only
/dependency-scan --fix # Auto-fix where possible
What This Skill Does
- Identifies package managers in your project
- Parses dependency manifests (package.json, requirements.txt, etc.)
- Checks vulnerability databases for known CVEs
- Reports severity and remediation options
- Optionally auto-fixes by updating to patched versions
Supported Package Managers
| Ecosystem | Files | Tool Used |
|---|
| Node.js | package.json, package-lock.json | npm audit |
| Python | requirements.txt, Pipfile, pyproject.toml | pip-audit, safety |
| Ruby | Gemfile, Gemfile.lock | bundler-audit |
| Java | pom.xml, build.gradle | dependency-check |
| Go | go.mod, go.sum | govulncheck |
| Rust | Cargo.toml, Cargo.lock | cargo-audit |
| PHP | composer.json, composer.lock | composer audit |
| .NET | *.csproj, packages.config | dotnet list --vulnerable |

Auto-Fix Behavior
Safe Fixes
Updates within semver-compatible range:
- Patch versions (1.2.3 → 1.2.4)
- Minor versions if locked to major (^1.2.3 → ^1.3.0)
Breaking Fixes
May introduce breaking changes:
- Major version updates
- Requires
--force flag

Configuration
Ignore Known Issues
Create .dependency-scan-ignore:
# Ignore specific CVEs (document reason!)
ignore:
- id: CVE-2021-23337
reason: "Not exploitable in our usage, lodash template not used"
expires: 2024-12-31
- id: GHSA-xxx-xxx
reason: "Development dependency only"
# Ignore packages
packages:
- name: lodash
versions: ["< 4.17.0"] # Only old versions
Severity Thresholds
# .dependency-scan.yaml
thresholds:
fail_on: critical # Fail CI on critical
warn_on: high # Warn on high
ignore_below: low # Don't report low
fix:
auto_fix: true
allow_major: false # No major version bumps

Dependency Health
Beyond CVEs
/dependency-scan --health
Additional checks:
- Outdated packages : Major versions behind
- Deprecated packages : No longer maintained
- License issues : Incompatible licenses
- Maintenance : Last update, open issues
