🔒 Containment

Level: maximum

Required:

APPROVE_POST: Can post publicly
SANDBOX_CONTAINER: Code execution capability

Recommended:

LOG_ACTIONS: Audit trail for all actions

⚡ Risks

Pipe-to-shell pattern detected (curl|bash) in: README.md, SKILL.md critical

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

SSH key access patterns in: README.md, setup.sh, SKILL.md, verify.sh high

Mitigation: Verify legitimate need for SSH access. Consider sandboxing.

Keychain/credential store access in: SKILL.md high

Mitigation: Block keychain access or use isolated environment.

Hardcoded secrets detected in: setup.sh, SKILL.md high

Mitigation: Remove hardcoded secrets. Use environment variables instead.

Unauthorized tool use: INSTRUCTED_BINARY_INSTALL, MCP_SYS_CRITICAL_ACCESS high

Mitigation: Avoid instructing agents to install arbitrary binaries; bundle dependencies or use sandboxed environments

Command injection risk: TIRITH_INSECURE_TLS high

Social engineering indicators: SOCIAL_ENG_VAGUE_DESCRIPTION low

Mitigation: Provide clear, detailed description of skill functionality
