🔒 Containment
Level: maximum
Required:
- SANDBOX_CONTAINER: Code execution capability
Recommended:
- LOG_ACTIONS: Audit trail for all actions
⚡ Risks
Base64 decode + execute pattern in: templates/scripts/utils.js critical
Mitigation: Decode and review obfuscated content before use.
Prompt injection patterns detected in: lib/browser-utils.sh high
Mitigation: Review SKILL.md for hidden instructions. Do not use with untrusted input.
Unauthorized tool use: TOOL_ABUSE_SYSTEM_MODIFICATION, MCP_SYS_CRITICAL_ACCESS critical
Mitigation: Remove system modification commands
Command injection risk: COMMAND_INJECTION_USER_INPUT, MCP_SCRIPT_TAGS high
Mitigation: Validate and sanitize all user inputs before using in commands
Social engineering indicators: SOCIAL_ENG_VAGUE_DESCRIPTION low
Mitigation: Provide clear, detailed description of skill functionality
