🔒 Containment

Level: maximum

Required:

SANDBOX_CONTAINER: Code execution capability

Recommended:

LOG_ACTIONS: Audit trail for all actions

⚡ Risks

Base64 decode + execute pattern in: scripts/core/utils.ts critical

Mitigation: Decode and review obfuscated content before use.

Prompt injection patterns detected in: scripts/core/config.ts high

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

Unauthorized tool use: TOOL_ABUSE_SYSTEM_MODIFICATION, INSTRUCTED_GIT_CLONE_AND_BUILD critical

Mitigation: Remove system modification commands

Command injection risk: TIRITH_DOTFILE_OVERWRITE, MCP_SQL_BLIND high

Social engineering indicators: SOCIAL_ENG_VAGUE_DESCRIPTION low

Mitigation: Provide clear, detailed description of skill functionality
