+# 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**
+- Scans dependencies against built-in vulnerability databases
+- 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
+- **Go**: go.mod, go.sum
+- **Rust**: Cargo.toml, Cargo.lock
+- **Ruby**: Gemfile, Gemfile.lock
+- **Java/Maven**: pom.xml, gradle.lockfile
+- **PHP**: composer.json, composer.lock
+- **C#/.NET**: packages.config, project.assets.json
+
+### 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
