name: crabukit description: Security scanner for OpenClaw skills with Clawdex integration. Analyzes SKILL.md and scripts for dangerous permissions, hardcoded secrets, shell injection vulnerabilities, and malicious code patterns. Automatically uses Clawdex database if installed for known-malicious skill detection. Use when (1) installing a skill from an untrusted source, (2) developing a skill before publishing, (3) auditing installed skills, or (4) running CI/CD security checks. metadata: clawdbot: emoji: "🔒" category: "security" files: - "pyproject.toml" - "crabukit//*.py" - "scripts//" - "tests/**/" - "README.md" - "LICENSE" - "CHANGELOG.md" install: - id: pip kind: pip package: . bins: [crabukit] label: Install crabukit from source

🔒 Crabukit

Security scanner for OpenClaw skills. Prevents installation of malicious or vulnerable skills by static analysis. Integrates with Clawdex for comprehensive protection.

Quick Start

# Safely install a skill (scans before installing)
crabukit install youtube-summarize

# Scan a local skill before installing
crabukit scan ./suspicious-skill/

# Scan an installed skill
crabukit scan /opt/homebrew/lib/node_modules/clawdbot/skills/unknown-skill

# CI mode - fail on high severity or above
crabukit scan ./my-skill --fail-on=high

# List all detection rules
crabukit list-rules

🔌 Clawdex Integration

Crabukit automatically integrates with Clawdex if installed:

# Install Clawdex for database-based protection
clawdhub install clawdex

# Now crabukit will:
# 1. Check Clawdex database (known 824+ malicious skills)
# 2. Run behavior analysis (zero-day detection)
# → Defense in depth!

Layered Protection:

• Clawdex: Database of known-bad skills (fast lookup)
• Crabukit: Behavior analysis for zero-days (static analysis)

What It Detects

Risk Scoring

Crabukit assigns a score (0-100) based on findings:

Exit Codes

• 0 - Scan completed, no findings at or above --fail-on threshold
• 1 - Findings at or above threshold detected
