· v2.1.1

High Risk

"First open-source AI sanitizer with local semantic detection. 7 layers + code block awareness + LLM intent analysis. Catches prompt injection, reverse shells, memory tampering, encoding evasion, trust abuse. 85% fewer false positives in v2.1. Zero cloud — your prompts stay on your machine."

🔒 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 critical

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

Prompt injection patterns detected in: skill_sanitizer.py, SKILL.md high

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

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

Mitigation: Remove destructive file operations.

Command injection risk: COMMAND_INJECTION_EVAL, MCP_CMD_REVERSE_SHELL critical

Mitigation: Avoid eval(), exec(), and compile(). Use safer alternatives like ast.literal_eval()

Social engineering indicators: SOCIAL_ENG_VAGUE_DESCRIPTION low

Mitigation: Provide clear, detailed description of skill functionality

Data exfiltration patterns: MCP_EXFIL_EXTERNAL_UPLOAD high

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