🔒 Containment

Level: maximum

Required:

SANDBOX_CONTAINER: Code execution capability

Recommended:

LOG_ACTIONS: Audit trail for all actions

⚡ Risks

Keychain/credential store access in: scripts/claude-usage.sh, SKILL.md high

Mitigation: Block keychain access or use isolated environment.

Prompt injection patterns detected in: SKILL.md high

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

Unauthorized tool use: MCP_SYS_CRITICAL_ACCESS, TOOL_ABUSE_SYSTEM_PACKAGE_INSTALL high

Mitigation: Avoid accessing system directories unless absolutely necessary.

Social engineering indicators: SOCIAL_ENG_VAGUE_DESCRIPTION, SOCIAL_ENG_ANTHROPIC_IMPERSONATION low

Mitigation: Provide clear, detailed description of skill functionality
