[!NOTE] vet supports special mode for Agent Skills. Run vet scan --agent-skill <owner/repo> to scan an Agent Skill hosted in a GitHub repository.

Why vet?

70-90% of modern software is open source code — how do you know it's safe?

Traditional SCA tools drown you in CVE noise. vet takes a different approach:

• Shadow AI discovery — Discover AI tool usage signals across various tools and configurations
• Catch malware before it ships — Zero-day detection through static and dynamic behavioral analysis (requires SafeDep Cloud access)
• Cut through vulnerability noise — Analyzes actual code usage to surface only the risks that matter
• Enforce policy as code — Express security, license, and quality requirements as CEL expressions
• CI/CD integration — Zero-config security guardrails in CI/CD

Free for open source. Hosted SaaS available at SafeDep.

Quick Start

Install in seconds:

# macOS & Linux
brew install safedep/tap/vet

# Using npm
npm install -g @safedep/vet

or download a pre-built binary

Get started immediately:

# Scan for malware in your dependencies
vet scan -D . --malware-query

# Fail CI on critical vulnerabilities
vet scan -D . --filter 'vulns.critical.exists(p, true)' --filter-fail

# Get API key for advanced malware detection
vet cloud quickstart

Architecture

vet follows a pipeline architecture: readers ingest package manifests from diverse sources (directories, repositories, container images, SBOMs), enrichers augment each package with vulnerability, malware, and scorecard data from SafeDep Cloud, the CEL policy engine evaluates security policies against enriched data, and reporters produce actionable output in formats like SARIF, JSON, and Markdown.

Key Features

Malicious Package Detection

Real-time protection against malicious packages powered by SafeDep Cloud. Free for open source projects. Detects zero-day malware through active code analysis.

Vulnerability Analysis

Unlike dependency scanners that flood you with noise, vet analyzes your actual code usage to prioritize real risks. See dependency usage evidence for details.

Policy as Code

Define security policies using CEL expressions to enforce context specific requirements:

# Block packages with critical CVEs
vet scan --filter 'vulns.critical.exists(p, true)' --filter-fail

# Enforce license compliance
vet scan --filter 'licenses.contains_license("GPL-3.0")' --filter-fail

# Require minimum OpenSSF Scorecard scores
vet scan --filter 'scorecard.scores.Maintained < 5' --filter-fail

Multi-Ecosystem Support

Package managers: npm, PyPI, Maven, Go, Ruby, Rust, PHP Container images: Docker, OCI SBOM formats: CycloneDX, SPDX Source repositories: GitHub, GitLab

Malicious Package Detection

Real-time protection against malicious packages with active scanning and behavioral analysis.

Quick Setup

# One-time setup for advanced scanning
vet cloud quickstart

# Scan for malware with active scanning (requires API key)
vet scan -D . --malware

# Query known malicious packages (no API key needed)
vet scan -D . --malware-query

Example detections:

• MAL-2025-3541: express-cookie-parser
• MAL-2025-4339: eslint-config-airbnb-compat
• MAL-2025-4029: ts-runtime-compat-check

Key security features:

• Real-time analysis against known malware databases
• Behavioral analysis using static and dynamic analysis
• Zero-day protection through active code scanning
• Human-in-the-loop triaging for high-impact findings
• Public analysis log for transparency

Advanced Usage

# Specialized scans
vet scan --vsx --malware                    # VS Code extensions
vet scan -D .github/workflows --malware     # GitHub Actions
vet scan --image nats:2.10 --malware        # Container images

# Analyze specific packages
vet inspect malware --purl pkg:npm/[email protected]
