Skill Scanner

Security scanner for OpenClaw agent skills. Static analysis for red flags.

Usage

node scripts/scanner.js <path-to-skill> [--verbose] [--json] [--summary] [--ignore <path>] [--include-self]

Examples

# Scan a downloaded skill folder before enabling it clawhub inspect some-skill node scripts/scanner.js ./skills/some-skill --verbose # Scan your own skill before publishing node scripts/scanner.js ./skills/my-skill # JSON output for automation node scripts/scanner.js ./skills/my-skill --json # One-line summary output for heartbeat checks node scripts/scanner.js ./skills/my-skill --summary # Include scanner internals (off by default to reduce self-scan noise) node scripts/scanner.js ./skills/skulk-skill-scanner --include-self

What It Catches

SeverityFlags🔴 CriticalData exfiltration, credential access, safety overrides, destructive commands🟠 HighObfuscation (base64/eval), unknown network access, env scanning, privilege escalation, hidden instructions🟡 MediumWrites outside workspace, package installs (supply chain), messaging on user's behalf, persistent timers/automation🔵 InfoAPI key references, broad tool access requests

Scoring

Each unique rule deducts points: critical=30, high=15, medium=5, info=0 Score 75-100: ✅ PASS Score 50-74: ⚠️ WARN Score 0-49 or any critical: ❌ FAIL Exit code 1 on FAIL (CI-friendly)

Safe Domain Allowlist

Known legitimate API domains are allowlisted to reduce false positives on network-related rules. Edit the SAFE_DOMAINS array in scripts/scanner.js to customize.

Limitations

This is static pattern matching — it catches obvious and moderately obfuscated attacks but cannot detect: Sophisticated multi-step social engineering Runtime-generated URLs or dynamic exfiltration Attacks that look identical to legitimate skill behavior It's a first line of defense, not a guarantee. Always review skills manually before granting sensitive access.
