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
This skill explicitly instructs bypassing sandbox protections by writing and executing arbitrary scripts and installing packages on the host environment, which enables remote code execution, data exfiltration, credential access, and supply-chain abuse.
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
This skill explicitly instructs the agent to bypass the sandbox by writing and executing arbitrary Python scripts on the host and suggests installing packages (pip3), which enables modification of the machine's filesystem and execution environment and thus bypasses sandbox security even though it doesn't request sudo or create users.
