🔒 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: README.md critical

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

Keychain/credential store access in: ollama-install.sh high

Mitigation: Block keychain access or use isolated environment.

Unauthorized tool use: TOOL_ABUSE_SYSTEM_PACKAGE_INSTALL, MCP_SYS_FILE_DESTRUCTION, MCP_SYS_CRITICAL_ACCESS, MCP_SYS_PRIVILEGE_ESCALATION, INSTRUCTED_BINARY_INSTALL critical

Mitigation: Use user-level installs without sudo

Command injection risk: COMMAND_INJECTION_USER_INPUT, TIRITH_INSECURE_TLS 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
