Critical

E005: Suspicious download URL detected in skill instructions.

What this means

Detected a suspicious URL in the skill instructions that could lead the agent to download and execute malicious scripts or binaries. This includes links to executables from untrusted sources, typosquatting of official packages, URL shorteners that obscure the destination, and personal file hosting services.

Why it was flagged

The git clone URL points to an unknown/unverified GitHub user repository which is a direct source of executable code (potential malware distribution), while the 127.0.0.1 API endpoint is a local Jupyter server address and not an external download source.

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 skill instructs running a headless JupyterLab server with token/password disabled (bypassing authentication) and cloning code into the user's home, which risks compromising the machine's state and security.
