๐Ÿ”’ Containment

Level: maximum

Required:
  • SANDBOX_CONTAINER: Code execution capability
Recommended:
  • LOG_ACTIONS: Audit trail for all actions

โšก Risks

Unauthorized tool use: TOOL_ABUSE_SYSTEM_MODIFICATION, INSTRUCTED_GIT_CLONE_AND_BUILD critical

Mitigation: Remove system modification commands

Command injection risk: MCP_SCRIPT_TAGS, MCP_SQL_BLIND, TIRITH_DOTFILE_OVERWRITE high

Mitigation: Remove embedded script tags and encoded payloads.

Social engineering indicators: SOCIAL_ENG_VAGUE_DESCRIPTION low

Mitigation: Provide clear, detailed description of skill functionality

Data exfiltration patterns: DATA_EXFIL_NETWORK_REQUESTS, DATA_EXFIL_ENV_VARS medium

Mitigation: Ensure network access is necessary and documented
