dependency-auditor
Audit and manage dependencies across multi-language projects. Identifies vulnerabilities, license conflicts, transitive dependency risks, and safe-upgrade paths. Use when auditing third-party packages before release, investigating a CVE, planning a major version bump, or running a license-compliance review. Examples: 'audit our npm dependencies', 'do we have GPL contamination', 'plan the upgrade to React 19'.

Describe the task
Ask your agent for something this skill covers. It loads dependency-auditor automatically when relevant.
- 03
Review the result

Dependency Auditor
Skill Type: POWERFUL · Category: Engineering · Domain: Dependency Management & Security
Offline, deterministic dependency auditing across 8+ package ecosystems. The three scripts are pattern-matchers over manifests/lockfiles — they do not call live advisory APIs; pair their findings with npm audit / pip-audit / cargo audit for current CVE coverage.
Quick Start
# 1. Scan for vulnerabilities (built-in offline CVE pattern set; exit non-zero on high severity)
python3 scripts/dep_scanner.py /path/to/project --format json --fail-on-high -o scan.json
# 2. Check license compliance and conflicts
python3 scripts/license_checker.py /path/to/project --policy strict --format json -o licenses.json
# 3. Plan upgrades from the scanner's inventory
python3 scripts/upgrade_planner.py scan.json --risk-threshold medium --timeline 90 --format json -o plan.json
Consume the outputs: scan.json findings drive which packages to pin/patch now; licenses.json conflicts go to the user as a legal-risk list; plan.json orders upgrades by risk with rollback notes. --quick-scan skips transitive deps; --security-only limits the plan to security fixes.
Verification loop: after applying upgrades, re-run step 1 and assert 0 high-severity findings before closing the audit.
Supported Ecosystems
| Language | Manifests parsed |
|---|---|
| JavaScript/Node | package.json, package-lock.json, yarn.lock |
| Python | requirements.txt, pyproject.toml, Pipfile.lock, poetry.lock |
| Go | go.mod, go.sum |
| Rust | Cargo.toml, Cargo.lock |
| Ruby | Gemfile, Gemfile.lock |
| Java | pom.xml, gradle.lockfile |
| PHP | composer.json, composer.lock |
| C#/.NET | packages.config, project.assets.json |
License Classification
- Permissive: MIT, Apache 2.0, BSD (2/3-clause), ISC
- Copyleft (strong): GPL v2/v3, AGPL v3 — flags contamination risk in permissive projects
- Copyleft (weak): LGPL v2.1/v3, MPL 2.0
- Proprietary / Dual / Unknown — unknown licenses are surfaced for manual review
The checker analyzes license inheritance through dependency chains and emits conflict pairs with remediation suggestions.
Upgrade Risk Matrix
| Risk | Update type | Handling |
|---|---|---|
| Low | Patch, security fixes | Apply immediately |
| Medium | Minor with new features | Batch into scheduled update |
| High | Major version, API changes | Dedicated migration task + tests |
| Critical | Known breaking changes | Planned migration with rollback procedure |
Prioritization: security patches > bug fixes > feature updates > major rewrites; deprecated features get immediate attention.
Scripts (accurate capability claims)
scripts/dep_scanner.py— multi-format parser; built-in offline vulnerability pattern set (~16 CVE patterns — a smoke layer, not a replacement for live advisories); transitive resolution from lockfiles; JSON + text output.scripts/license_checker.py— license detection from package metadata; compatibility matrix across 20+ license types;--policy permissive|strict; conflict detection with remediation.scripts/upgrade_planner.py— semver-based breaking-change prediction; risk-ordered migration plan with testing checklist and timeline estimation.
Sample fixtures: test-project/ and test-inventory.json in this folder; expected shapes in expected_outputs/.
CI Integration
# Security gate in CI
python3 scripts/dep_scanner.py . --format json --fail-on-high
python3 scripts/license_checker.py . --policy strict --format json
Best Practices
- Prioritize security: address high/critical findings immediately; license compliance before functionality.
- Gradual updates: incremental upgrades with thorough testing; feature flags for risky bumps.
- Cadence: security scans per commit; license audits monthly; full audit quarterly.
- False positives: whitelist with documentation; contact maintainers for license ambiguity.
See README.md for detailed usage and references/ for the vulnerability/license knowledge bases.
FAQ
What does the dependency-auditor skill do?
Audit and manage dependencies across multi-language projects. Identifies vulnerabilities, license conflicts, transitive dependency risks, and safe-upgrade paths. Use when auditing third-party packages before release, investigating a CVE, planning a major version bump, or running a license-compliance review. Examples: 'audit our npm dependencies', 'do we have GPL contamination', 'plan the upgrade to React 19'.
How do I install dependency-auditor?
Run npx skills add https://github.com/alirezarezvani/claude-skills --skill dependency-auditor in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/dependency-auditor/ (personal) or .claude/skills/dependency-auditor/ (project).
Which AI agents can use dependency-auditor?
Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.
Is dependency-auditor safe to install?
No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.
Who maintains dependency-auditor?
It is published by alirezarezvani in alirezarezvani/claude-skills. It has 691 recorded installs.
