DojoGenesis Dependency Auditor
Skill Type: POWERFUL
Category: Engineering
Domain: Dependency Management & Security
Overview
The Dependency Auditor is a comprehensive toolkit for analyzing, auditing, and managing dependencies across multi-language software projects. This skill provides deep visibility into your project's dependency ecosystem, enabling teams to identify vulnerabilities, ensure license compliance, optimize dependency trees, and plan safe upgrades.
In modern software development, dependencies form complex webs that can introduce significant security, legal, and maintenance risks. A single project might have hundreds of direct and transitive dependencies, each potentially introducing vulnerabilities, license conflicts, or maintenance burden. This skill addresses these challenges through automated analysis and actionable recommendations.
Core Capabilities
1. Vulnerability Scanning & CVE Matching
Comprehensive Security Analysis

- Matches Common Vulnerabilities and Exposures (CVE) patterns
- Identifies known security issues across multiple ecosystems
- Analyzes transitive dependency vulnerabilities
- Provides CVSS scores and exploit assessments
- Tracks vulnerability disclosure timelines
- Maps vulnerabilities to dependency paths
Multi-Language Support
- JavaScript/Node.js: package.json, package-lock.json, yarn.lock
- Python: requirements.txt, pyproject.toml, Pipfile.lock, poetry.lock

2. License Compliance & Legal Risk Assessment
License Classification System
- Permissive Licenses: MIT, Apache 2.0, BSD (2-clause, 3-clause), ISC
- Copyleft (Strong): GPL (v2, v3), AGPL (v3)
- Copyleft (Weak): LGPL (v2.1, v3), MPL (v2.0)
- Proprietary: Commercial, custom, or restrictive licenses
- Dual Licensed: Multi-license scenarios and compatibility
- Unknown/Ambiguous: Missing or unclear licensing
Conflict Detection
- Identifies incompatible license combinations
- Warns about GPL contamination in permissive projects
- Analyzes license inheritance through dependency chains
- Provides compliance recommendations for distribution
- Generates legal risk matrices for decision-making
3. Outdated Dependency Detection
Version Analysis
- Identifies dependencies with available updates
- Categorizes updates by severity (patch, minor, major)
- Detects pinned versions that may be outdated
- Analyzes semantic versioning patterns
- Identifies floating version specifiers
- Tracks release frequencies and maintenance status
Maintenance Status Assessment
- Identifies abandoned or unmaintained packages
- Analyzes commit frequency and contributor activity
- Tracks last release dates and security patch availability
- Identifies packages with known end-of-life dates
- Assesses upstream maintenance quality
4. Dependency Bloat Analysis
Unused Dependency Detection
- Identifies dependencies that aren't actually imported/used
- Analyzes import statements and usage patterns
- Detects redundant dependencies with overlapping functionality
- Identifies oversized packages for simple use cases
- Maps actual vs. declared dependency usage
Redundancy Analysis
- Identifies multiple packages providing similar functionality
- Detects version conflicts in transitive dependencies
- Analyzes bundle size impact of dependencies
- Identifies opportunities for dependency consolidation
- Maps dependency overlap and duplication
5. Upgrade Path Planning & Breaking Change Risk
Semantic Versioning Analysis
- Analyzes semver patterns to predict breaking changes
- Identifies safe upgrade paths (patch/minor versions)
- Flags major version updates requiring attention
- Tracks breaking changes across dependency updates
- Provides rollback strategies for failed upgrades
Risk Assessment Matrix
- Low Risk: Patch updates, security fixes
- Medium Risk: Minor updates with new features
- High Risk: Major version updates, API changes
- Critical Risk: Dependencies with known breaking changes
Upgrade Prioritization
- Security patches: Highest priority
- Bug fixes: High priority
- Feature updates: Medium priority
- Major rewrites: Planned priority
- Deprecated features: Immediate attention
6. Supply Chain Security
Dependency Provenance
- Verifies package signatures and checksums
- Analyzes package download sources and mirrors
- Identifies suspicious or compromised packages
- Tracks package ownership changes and maintainer shifts
- Detects typosquatting and malicious packages
Transitive Risk Analysis
- Maps complete dependency trees
- Identifies high-risk transitive dependencies
- Analyzes dependency depth and complexity
- Tracks influence of indirect dependencies
- Provides supply chain risk scoring
7. Lockfile Analysis & Deterministic Builds
Lockfile Validation
- Ensures lockfiles are up-to-date with manifests
- Validates integrity hashes and version consistency
- Identifies drift between environments
- Analyzes lockfile conflicts and resolution strategies
- Ensures deterministic, reproducible builds
Environment Consistency
- Compares dependencies across environments (dev/staging/prod)
- Identifies version mismatches between team members
- Validates CI/CD environment consistency
- Tracks dependency resolution differences
