Skill instructions

Skill Security Scanner

Scan skills for malicious patterns before installation. Detects credential exfiltration, suspicious network calls, obfuscated code, prompt injection, and other red flags.

Quick Start

# Scan a local skill folder
python3 scripts/scan.py /path/to/skill

# Verbose output (show matched lines)
python3 scripts/scan.py /path/to/skill --verbose

# JSON output (for automation)
python3 scripts/scan.py /path/to/skill --json

Workflow: Scan Before Install

  1. Download or locate the skill folder
  2. Run python3 scripts/scan.py <skill-path> --verbose
  3. Review findings by severity (CRITICAL/HIGH = do not install)
  4. Report results to user with recommendation

Score Interpretation

Score Meaning Recommendation
CLEAN No issues found Safe to install
INFO Minor notes only Safe to install
REVIEW Medium-severity findings Review manually before installing
SUSPICIOUS High-severity findings Do NOT install without thorough manual review
DANGEROUS Critical findings detected Do NOT install — likely malicious

Exit Codes

  • 0 = CLEAN/INFO
  • 1 = REVIEW
  • 2 = SUSPICIOUS
  • 3 = DANGEROUS

Rules Reference

See references/rules.md for full list of detection rules, severity levels, and whitelisted domains.

Limitations

  • Pattern-based detection — cannot catch all obfuscation techniques
  • No runtime analysis — only static scanning
  • False positives possible for legitimate tools that access network/files
  • Always combine with manual review for HIGH/MEDIUM findings
