Skill

· v0.6.1

High Risk

"Security audit tool for ClawHub skills. Scans a skill directory with 65 detection patterns, anti-obfuscation analysis, and dual rating system (Security + Compliance). v0.6.1 fixes batch scan performance by skipping venv/node_modules directories. Use when: installing a new skill, reviewing skill safety, or auditing permissions."

🔒 Containment

Level: maximum

Required:

SANDBOX_CONTAINER: Code execution capability

Recommended:

LOG_ACTIONS: Audit trail for all actions

⚡ Risks

Pipe-to-shell pattern detected (curl|bash) in: scripts/scan.py, scripts/test_scan.py critical

Mitigation: Do not execute. Review source for malicious intent.

Keychain/credential store access in: scripts/scan.py, SKILL.md high

Mitigation: Block keychain access or use isolated environment.

Code obfuscation detected in: scripts/scan.py medium

Mitigation: Deobfuscate and review code before use.

Unauthorized tool use: MCP_SYS_FILE_DESTRUCTION, MCP_SYS_PERMISSION_MANIPULATION, TOOL_ABUSE_SYSTEM_MODIFICATION critical

Mitigation: Remove destructive file operations.

Command injection risk: COMMAND_INJECTION_EVAL, COMMAND_INJECTION_SHELL_TRUE critical

Mitigation: Avoid eval(), exec(), and compile(). Use safer alternatives like ast.literal_eval()

Social engineering indicators: SOCIAL_ENG_VAGUE_DESCRIPTION low

Mitigation: Provide clear, detailed description of skill functionality

Data exfiltration patterns: DATA_EXFIL_ENV_VARS medium

Mitigation: Minimize access to environment variables
