🔒 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: SKILL.md, README.md critical

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

Prompt injection patterns detected in: SKILL.md, scripts/firewall-scan.sh, README.md high

Mitigation: Review SKILL.md for hidden instructions. Do not use with untrusted input.

Unauthorized tool use: INSTRUCTED_BINARY_INSTALL, TOOL_ABUSE_SYSTEM_MODIFICATION, MCP_SYS_FILE_DESTRUCTION, MCP_SYS_PERMISSION_MANIPULATION, MCP_SYS_CRITICAL_ACCESS critical

Mitigation: Avoid instructing agents to install arbitrary binaries; bundle dependencies or use sandboxed environments

Command injection risk: TIRITH_PLAIN_HTTP_EXEC high

Social engineering indicators: SOCIAL_ENG_VAGUE_DESCRIPTION low

Mitigation: Provide clear, detailed description of skill functionality

Tool poisoning: hidden behaviors detected (MCP_TOOL_POISONING_SENSITIVE_DATA) high

Mitigation: Remove references to sensitive data collection.

Data exfiltration patterns: MCP_EXFIL_EXTERNAL_UPLOAD high

Mitigation: Document all external data transfers. Remove suspicious upload references.
