Critical

E006: Malicious code pattern detected in skill scripts.

What this means

Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.

Why it was flagged

High-risk offensive playbook: it contains explicit path-traversal payloads and instructions to locate vulnerable sinks and confirm unauthorized file read/write, which can be used to exfiltrate sensitive files and enable unauthorized access.

Report incorrect finding
Medium

W013: Attempt to modify system services in skill instructions.

What this means

The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.

Why it was flagged

The playbook explicitly lists payloads targeting sensitive system files (e.g., /etc/passwd) and instructs the tester to "Confirm unauthorized file read/write outside allowed directory," which encourages attempting writes or reads that can modify or expose system state outside intended bounds.
