🔒 Containment

Level: maximum

Recommended:

LOG_ACTIONS: Audit trail for all actions

⚡ Risks

Social engineering indicators: SOCIAL_ENG_VAGUE_DESCRIPTION low

Mitigation: Provide clear, detailed description of skill functionality

Tool poisoning: hidden behaviors detected (MCP_TOOL_POISONING_DECEPTION) critical

Mitigation: Remove deceptive language. Tools must be transparent about their behavior.

Data exfiltration patterns: INSTRUCTED_SENSITIVE_SERVICE_ACCESS high

Mitigation: Clearly document which sensitive services are accessed and why; use minimal required permissions
